Note: Acceptance of this disclaimer is required before utilizing any therapeutic modules within the suite.

The Trahreg Tinnitus Therapy Suite is a research-oriented platform built on three core pillars:

• Evidence-Based Tools: Digital implementations of established protocols like Notch Therapy and Acoustic CR.
• Clinical Transparency: Tools to measure Minimum Masking Levels (MML) and track THI progress.
• Privacy-First Design: A "Zero-Knowledge" architecture where all data stays on your local device.

Our goal is to facilitate Habituation—the neuroplastic process where the brain learns to reclassify the tinnitus signal as a neutral, non-threatening background sound.

Therapy Selection Matrix

Before You Begin: System Readiness

• Hardware: Use high-quality, wired, over-ear headphones. Open-back models are preferred for natural spatial imaging. Avoid Bluetooth "Hands-Free" (AG) mode.
• OS Audio: Disable "Spatial Sound," "Dolby Atmos," "Windows Sonic," or any "Bass Boost" effects.
• Sample Rate: Ensure your system is set to 44.1 kHz or 48 kHz. High-frequency filters require this precision to remain stable.
• Safe Levels: Sound therapy should never be painful. Aim for a listening level below 70 dB (comfortable conversation level).
• Environment: Conduct your calibration in a quiet room to ensure accurate Pitch Matching.

Which Therapy Should I Use? (Selection Matrix)

The Five Golden Rules

• Rule 1: The Mixing Point. Therapy volume must be set so the sound and your tinnitus "mix" like two colors of paint. Total masking (hiding the tinnitus completely) prevents habituation; your brain must still perceive the signal to learn it is neutral.

Visual: The Mixing Point

Figure: Both signals must be audible for the brain to habituate.

• Rule 2: Passive Listening. Treat therapy like background "wallpaper." Do not focus on the sound; instead, engage in work, reading, or relaxation while the engine runs.
• Rule 3: Consistency. Neuroplasticity takes time. Aim for 30–60 minutes of focused therapy daily for at least 3 months.
• Rule 4: AI Support. If you experience a "spike" in distress, use the AI-powered CBT Assistant for immediate reframing and coping strategies rather than simply increasing the volume.
• Rule 5: Clinical Visibility. Regularly export your Clinical PDF Reports to share objective progress (THI and MML trends) with your audiologist.
• Rule 6: Audio Integrity. You must disable OS-level enhancements like Windows "Sonic," Dolby Atmos, or "Bass Boost," as these distort the calibrated therapy filters.

Protocol for Success (Phases)

1. Phase 1: Validation. Run System Validation weekly. This ensures your headphones are in-phase and the browser audio engine is delivering accurate signals.
2. Phase 2: Pitch Match. Use the Notch Finder. Accuracy is critical; if your Pitch Match is off by more than 5%, Notch and CR therapies lose clinical effectiveness.
3. Phase 3: Calibration. Set your therapy volume to the Mixing Point (slightly lower than your tinnitus). Total masking prevents the brain from habituating.
4. Phase 4: Active Habituation. Use the session timer and engage in non-auditory tasks. The goal is for the sound to fade into the background.
5. Phase 5: Data Correlation. Review "AI Insights" weekly to identify if sleep, stress, or environment are triggering spikes.
6. Phase 6: Monthly Review. Every 30 days, generate a Clinical PDF. Look for a 7-point drop in THI scores as a marker of success.

• AI Assistant: Integrated into the CBT and Insight modules for real-time reframing and sound recipe suggestions.

Purpose: Tinnitus is often associated with pathological neural synchrony. Decorrelation presents independent, unrelated noise signals to each ear, preventing the brain from "merging" the sound into a central image. This aims to disrupt the synchronized firing patterns in the auditory cortex.

Step-by-Step Tutorial

1. Hardware: Connect high-quality headphones. True decorrelation requires two discrete signals.
2. Sound Choice: Select a noise color (Pink is recommended for long-term comfort).
3. Calibration: Adjust the Decorrelation slider until the sound feels "wide" and fills your head, rather than being a single point.
4. Volume: Set to the Mixing Point.

Field Guide

• Decorrelation Slider: Controls the independence of the L/R channels. 0% is identical (Mono); 100% is fully unrelated noise.
• Noise Color:
  • Pink: Equal energy per octave; mirrors natural sound distribution.
  • White: Equal energy per frequency; effective for aggressive masking.
  • Brown: Heavy low-frequency emphasis; best for low-pitched "roaring" tinnitus.
• EQ Sliders: Manually boost frequencies (2kHz to 12kHz) where you have known hearing loss to reduce "listening effort."

Pro-Tips

• If decorrelation feels "dizzying," reduce the slider to 50% until your brain adjusts to the wider soundstage.

Purpose: Based on Tailored Notched Music Training (TMNMT), this therapy removes sound energy from a narrow band centered on your tinnitus pitch. This stimulates Lateral Inhibition: the stimulated neurons surrounding the notch actively suppress the hyperactive, tinnitus-producing neurons inside the notch. (Ref: Okamoto et al., 2010)

Step-by-Step Tutorial

1. Pitch Match: Use the Notch Finder to determine your Center Frequency.
2. Frequency Entry: Input that frequency into the Notch Center field.
3. Width: Ensure Notch Width is set to 1.0 octaves (the clinical standard).
4. Mixing: Set the volume so you can still perceive your tinnitus "inside" the silent notch in the noise.

Field Guide

• Notch Center (Hz): The frequency of your tinnitus. Every slider movement here shifts the "silence" in the sound.
• Notch Width (Octaves): The size of the frequency "hole." 1.0 is standard; smaller widths require higher pitch-matching precision.
• Source Selector: Choose between Internal Noise, a Custom MP3, or Live Audio (e.g., Spotify processed through the notch).

Pro-Tips

• Re-verify your Pitch Match monthly. Tinnitus pitch can shift slightly as habituation begins.

Purpose: Inspired by bimodal devices like Lenire, this experimental module pairs structured auditory patterns (carrier tones, modulated noise, and tone bursts) with tactile feedback (haptics). By stimulating both the auditory and somatosensory systems simultaneously, the brain is encouraged to re-prioritize external signals over the internal tinnitus signal. (Ref: TENT-A Trial, 2020)

Step-by-Step Tutorial

1. Device: Best used on a smartphone held in the hand.
2. Activation: Enable Tactile Haptic Pulse.
3. Sensitivity: Adjust the Trigger Sensitivity until the phone vibrates only when you hear a distinct audio burst.
4. Rhythm: Use the Pulse Rate slider to match the visual pacer to your resting breathing rate (usually 5-6 BPM).

Field Guide

• Carrier Freq (Hz): Sets the pitch of the tone bursts. Ideally set near your tinnitus frequency or a complementary low tone.
• Noise Mod (Hz): The speed at which the background noise "shimmers" (amplitude modulation).
• Burst Rate (Hz): How many audio pulses occur per second.
• Tone/Noise Mix: Slides between pure bursts (1.0) and pure modulated noise (0.0). A 50/50 mix is standard.
• Haptic Strength: Controls how forcefully the phone vibrates during a trigger.

Pro-Tips

• Use a phone case with good vibration transmission to maximize the somatosensory effect.

Purpose: The foundational tool for Tinnitus Retraining Therapy (TRT). It provides constant, neutral sound enrichment to reduce the "contrast" between the tinnitus signal and a silent environment, preventing the brain's internal gain from increasing.

Step-by-Step Tutorial

1. Selection: Choose a sound you find neutral (Pink Noise) or pleasant (Rain/Ocean).
2. Calibration: Use the Mixing Point rule. The sound should be audible but not hide the tinnitus.
3. Duration: Use for 24/7 enrichment at low levels, or set a 60-minute timer for a focused session.

Procedural Wind Chimes

Dynamic Texture: A generator that creates a randomized, non-repeating sequence of consonant musical 'strikes' using high-Q impulsive oscillators.

• Mathematical Consonance: The chime intervals are based on standard musical ratios (1.2, 1.5, 1.875, etc.) derived from your tinnitus pitch. This ensures the soundscape feels harmonic and grounded.
• Non-Fatiguing: Unlike static noise or looping nature recordings, the procedural nature of the strikes prevents neural adaptation, making it an excellent choice for long therapy sessions.
• High-Frequency Coverage: Because the chimes are centered around your matched pitch, they provide targeted energy for habituation even in high-frequency ranges where nature sounds may be thin.

Field Guide

• Noise Selection: Buttons for White, Pink, Brown, Blue, Violet, and Forest. Pink is the research standard for habituation.
• Wind Chimes: A procedural soundscape utilizing high-Q impulsive oscillators. It creates a sequence of consonant 'strikes' mathematically related to your tinnitus pitch, offering a relaxing, organic alternative to static noise.
• L/R Balance: Moves the sound toward your "tinnitus side." Important if your tinnitus is louder in one ear.
• Sleep Fade: When checked, the volume will slowly ramp down to zero over 60 seconds at the end of your timer to prevent an autonomic "rebound" spike.
• 4-7-8 Pacer: A visual and auditory breathing guide. Inhale for 4s, Hold for 7s, Exhale for 8s. Use during high-distress spikes.

Pro-Tips

• If Pink Noise feels too sharp, switch to Brown Noise, which has a smoother, deeper profile similar to heavy rain.

Purpose: Developed by Prof. Peter Tass, this neuromodulation protocol uses pseudo-random sequences of four tones mathematically calculated relative to your tinnitus pitch. The goal is to desynchronize the pathological neural loops responsible for tonal tinnitus. (Ref: Tass et al., 2012)

Step-by-Step Tutorial

1. Pitch Match: Use the Pitch Bracketing tool to find your exact Center Frequency.
2. Calculation: Enter this frequency into the Center Frequency field and click "Calculate."
3. Balancing: This is critical. Play the sequence and adjust the Bal 1-4 sliders until all four tones sound exactly as loud as each other to your ears.
4. Protocol: Follow the "3-on/2-off" pattern. 60-minute sessions are recommended.

Field Guide

• Tone Grid: Displays the active therapeutic frequencies. A highlighted box indicates which tone is currently firing.
• Bal Sliders (1-4): Adjusts individual tone volumes. Use these to compensate for hearing loss at specific frequencies.
• Cycle Dots: A row of 5 dots. 3 solid dots (Active cycles) and 2 dashed dots (Silence cycles). This ensures the brain does not "adapt" to the sequence.

Pro-Tips

• Do not use CR tones as a masking sound. They should be played at a comfortable, audible level, but generally lower than the Mixing Point used for noise.

Purpose: Utilizes the Frequency Following Response (FFR). By playing two slightly different frequencies in each ear, the brain "perceives" a third, internal beat frequency. This can be used to induce Alpha, Theta (relaxation), or Delta (deep sleep) states, helping to down-regulate a stressed nervous system.

Step-by-Step Tutorial

1. Hardware: Ensure stereo headphones are connected.
2. Selection: Choose Delta for sleep or Theta for relaxation.
3. Calibration: Set volume to a level that is comfortable and soothing.
4. Listening: Close your eyes and focus on your breathing.

Field Guide

• Stereo Separation: You MUST use headphones. Without discrete L/R separation, the binaural effect is lost.
• Delta (1-4Hz): Induces deep, restorative sleep.
• Theta (4-8Hz): Induces meditative, relaxed states; ideal for anxiety management.
• Alpha (8-13Hz): Promotes calm focus.

Pro-Tips

• Binaural beats can be layered with Broadband Sound for enhanced comfort during sleep transitions.

Purpose: A 25-item clinically validated tool that measures the functional, emotional, and catastrophic impact of tinnitus on your life. It categorizes severity into Grade 1 (Slight) through Grade 5 (Catastrophic).

Usage: Take the assessment every 30 days. Your progress is measured by a reduction in this score, not necessarily a change in the volume of the sound.

Purpose: Tinnitus distress is often driven by the Limbic System (the brain's emotion center). This tool uses interactive Thought Records to help you identify negative "Automatic Thoughts" and reframe them into objective "Balanced Thoughts," facilitating habituation.

How to Use

1. Log: Record a situation where tinnitus was distressing.
2. Identify: Write down the thought you had (e.g., "This will never stop").
3. AI Assist: Use the Balanced Thought button to generate a clinical TRT reframing suggestion.

Purpose: Tinnitus and physiological stress exist in a feedback loop. This module provides Progressive Muscle Relaxation (PMR) guides and the 4-7-8 Breathing Pacer to de-escalate the autonomic nervous system.

Purpose: An algorithmic tool that analyzes your THI scores and MML levels to suggest the most effective therapy for your specific grade of tinnitus. For example, high distress levels will prioritize CBT and Relaxation, while lower distress with tonal tinnitus will prioritize Notch therapy.

Mental Health Spike Protocol

If a tinnitus "spike" causes high emotional distress, clinicians recommend switching focus from Sound Therapy to CBT & Wellness. Managing the limbic system's reaction—getting your body out of "fight or flight"—is more important than the acoustic signal during a spike.

Purpose: Accurate pitch matching is the foundation of Notch and CR therapies. The Notch Finder identifies your "Center Frequency"—the specific pitch of your tinnitus.

How to Match Your Pitch

1. Environment: Sit in a quiet room with headphones.
2. Search: Move the Frequency Slider slowly until the external tone matches your internal sound to find the Pitch Match.
3. Bracketing Strategy: Once you find a potential match, move the slider 500Hz above and below. If the tinnitus "disappears" or "beats" with the tone, you are close.
4. Octave Verification: This is the most critical step. Click /2 (Half). If the lower tone still sounds like your tinnitus, the original was a harmonic. The lowest clear match is your fundamental frequency.
5. Two-Tone Comparison: If you are stuck, use the Two-Tone module to compare Tone A and Tone B to "bracket" the sound.

Field Guide

• Frequency (Hz): The current test pitch. Can be entered manually for precision.
• Auto-Sweep Speed: Sets the rate at which the tone automatically climbs the frequency range. Many users find it easier to identify their pitch while the sound is moving.
• Save Frequency: Saves the match globally so it is automatically applied to Notch and CR therapy modules.

Purpose: Diagnostic aid to avoid octave errors. Allows A/B comparison between two distinct frequencies.

Purpose: A 10-second logarithmic sweep from 20Hz to 20,000Hz. Useful for identifying "dead zones" in hearing or specific frequencies that trigger a "reactive" increase in tinnitus volume.

Maps your Minimum Masking Level (MML) across the spectrum. A "steep" curve calculates a high Q-factor, indicating tonal tinnitus, while a flat curve suggests broadband noise-like tinnitus.

Purpose: Measures how your subjective perception of loudness grows relative to objective volume increments. This detects Hyperacusis (sound sensitivity) or Recruitment. Tutorial: Play the tone and rate its loudness from "Very Soft" to "Uncomfortable."

Residual Inhibition (RI): Measures the temporary silence or volume reduction after 60 seconds of high-level sound exposure.

1. Step 1: Play noise at a level that completely hides your tinnitus for 60 seconds.
2. Step 2: The noise stops. Use the stopwatch to time how many seconds it takes for your tinnitus to return to normal.
3. Insight: Increasing RI duration over months is a positive indicator of auditory system responsiveness.

Hearing Range Test: Tinnitus is often a "compensation" for auditory deprivation. Use this tool to explore your audibility thresholds across the spectrum (20Hz to 20kHz) and identify shifts in hearing.

Hearing Profile (Audiogram)

The suite allows you to enter your professional audiogram results (0dB to 110dB HL) for frequencies between 250Hz and 12kHz. This data is used to personalize your therapy.

• The Half-Gain Rule: A clinical standard for hearing compensation. The suite calculates a therapeutic boost equal to half of your recorded hearing loss (e.g., a 40dB loss results in a 20dB boost).
• Digital Safety Ceiling: To prevent clipping or acoustic trauma, the maximum digital boost is capped at 20dB.
• Auto-Compensation: Once saved, your profile automatically adjusts the output of the Sound Therapy, Notch, and Lenire-style modules to ensure frequencies you struggle to hear are properly stimulated.

Tinnitus Side Preset

On the Audiogram page, you can select your Tinnitus Side (Left, Right, or Both). This sets a global intelligent default for the L/R balance in all therapy modules, ensuring the sound is immediately centered or biased toward the appropriate ear upon starting a session.

AI-Powered Features (Gemini): Leverages client-side AI (via your own API key) to provide therapeutic support. All data is anonymized before processing.

• "Spike" De-escalator: Provides immediate CBT reframing during periods of high distress.
• Soundscape Designer: Suggests "Sound Recipes" based on natural language descriptions (e.g., "high-pitched hiss" -> "Pink Noise with Stream").
• Pattern Correlation: Identifies non-obvious links between your sleep, usage, and distress scores.
• Clinical Report Translator: Generates a professional summary of your progress for your doctor.
• Grounding Script Generation: Located in the Thought Record module, this tool generates a personalized 1-minute mindfulness script based on your specific "Balanced Thought."

Spectrogram: A real-time visualizer of audio frequencies. Use this to verify your Notch (look for the "hole" in the graph) or Acoustic CR tone alignment.

Audio Level Meter: Displays real-time environmental volume. Habituation is most effective in environments between 45dB and 60dB.

The feedback tool allows users to submit technical bug reports or feature requests. To maintain clinical privacy, you can generate a technical log file to send via email rather than using a persistent database or third-party tracking.

High-frequency therapy requires extreme technical precision. This engine audits your hardware and browser settings weekly:

• Notch Depth Check: Verifies your filters are achieving at least 40dB of attenuation.
• Phase Test: Ensures L/R channels are not inverted.
• Sample Rate Check: Confirms your system is not running in low-fidelity "Hands-Free" mode.

Automated Audio Watchdog: Browsers often "suspend" audio in background tabs to save power. This background observer detects stalls and automatically attempts to resume the session, ensuring uninterrupted therapy even when the screen is off.

Audio Status Indicator

Located in the top navigation bar, this provides real-time engine feedback:

• ● Audio Active: The engine is processing sound normally.
• ● Audio Suspended: The browser has paused the audio. Simply interact with the page (click any button) to resume playback.
• Recovery Notification: If the engine detects a stall (silence during active therapy), a floating orange notification will appear at the top of the screen as the Watchdog attempts an automated restart.

Purpose: Long-duration exposure to high-energy sounds, particularly low-frequency noise (Red/Brown), can stress audio hardware. The suite includes real-time safeguards to protect your equipment.

• Intelligent RMS Limiter: Monitors the total power of the audio signal. If the sound becomes too intense (risking digital clipping), the limiter smoothly reduces the gain to preserve audio quality while protecting your transducers.
• DC Blocking Filters: Integrated into all procedural noise colors (Pink, Brown, Red, Rain). These filters remove 'DC offset' and sub-sonic drift below 20Hz, preventing voice coil heat buildup during long sessions.
• Saturation Recovery: The Audio Watchdog monitors for 'DC Saturation'. If a signal becomes stuck, the system performs an automated hard reset to restore clinical safety.

Clinical Onboarding: Access to therapy modules is gated behind a mandatory 5-step sequence to ensure user safety and technical accuracy.

• Step 1 (Disclaimer): Mandatory acknowledgement that the suite is a research tool, not a medical device.
• Step 2 (Hearing Aid Check): Critical safety step. If you are wearing hearing aids (physical or Bluetooth) during therapy, the software's Hearing Boost feature is automatically disabled to prevent double-amplification and potential acoustic trauma.
• Step 3 (Calibration): Encourages initial setup of the Hearing Profile and Pitch Match.

Clinical FAQ

Is this a medical device? No. It is an educational and research tool. It is not intended to diagnose or treat medical conditions.

How loud should the therapy be? Always use the Mixing Point. Total masking hides the signal from the brain, preventing it from learning to ignore the tinnitus. Maintain levels below 70dB to avoid acoustic fatigue.

Bluetooth Warning: While convenient, Bluetooth introduces latency (delay). This is acceptable for simple noise, but can disrupt the precise 1.5Hz timing of Acoustic CR and the synchronization of Bimodal Haptics. Wired headphones are recommended for neuromodulation.

Sample Rate Check: Ensure your OS is set to 44.1kHz. Higher sample rates (96kHz+) are supported but unnecessary; rates below 44.1kHz (Bluetooth AG mode) will cause digital aliasing and render therapy ineffective.

Stereo Verification Protocol

Precise stereo separation is required for Decorrelation and Binaural Beats. To verify your hardware:

1. Open the System Validation engine.
2. Run the Phase Test.
3. If the "In-Phase" tone sounds diffuse or wide, your system is incorrectly down-mixing to Mono or using "Virtual Surround." Disable these in your sound settings.

The suite is built to facilitate seamless communication between patients and healthcare providers. Remote Patient Monitoring (RPM) can be configured to support clinicians using CPT code 99454.

Habituation: The neuroplastic process where the brain filters out the tinnitus signal from conscious awareness.

Lateral Inhibition: A physiological process where stimulated neurons suppress the activity of their overactive neighbors (the mechanism behind Notch Therapy).

Minimum Masking Level (MML): The lowest volume level of noise required to just barely hide the tinnitus sound.

Residual Inhibition (RI): The temporary reduction or suppression of tinnitus volume following sound exposure.

Q-factor: A measure of the sharpness of an auditory filter; high Q indicates very tonal tinnitus.

Recruitment: A condition where loudness perception increases abnormally fast, often associated with hearing loss and hyperacusis.

A specialized utility for generating broadband noise with scientific precision, mirroring Python signal-processing behavior. Uses Paul Kellet filter banks for Pink noise and lossy integrators for Brown noise.

Table 1: Protocol Quick Start Summary

This appendix is designed for audiologists and ENTs using the Trahreg Suite for patient monitoring and auditory rehabilitation.

Clinical Metrics Thresholds

• THI Significance: A drop of ≥ 7 points in the Tinnitus Handicap Inventory is the minimum clinically significant difference (MCSD).
• Q-Factor Interpretation: High Q values (> 3.0) suggest tonal tinnitus localized to specific neural clusters. Low Q values (< 1.5) suggest a broader, noise-like perception involving multiple auditory channels.
• RI Depth: Patients exhibiting "Total RI" (complete silence) typically show higher responsiveness to neuromodulation protocols (ACR/Notch).

Therapy Selection Matrix

Remote Monitoring (CPT 99454)

Clinicians can utilize the suite’s automated reporting to satisfy requirements for CPT 99454 (Remote monitoring of physiologic parameter(s) via patient-managed device). Documentation provided in the Clinical PDF includes:

• Patient adherence logs (daily therapy minutes).
• Monthly distress assessments (THI).
• Serial psychophysical measures (MML/RI).

Clinicians should verify specific documentation requirements with their local payers.

Protocol Compliance Checklist (Patient)

Use this checklist to ensure adherence to clinical habituation protocols. Consistency is the primary driver of successful neuroplasticity.

Most technical issues in sound therapy arise from OS-level audio processing or hardware limitations. Follow this guide to ensure your system is providing clinically accurate output.

1. Bluetooth Connectivity Issues

• The "Hands-Free" Trap: Many Bluetooth headphones have two modes: "Stereo" and "Hands-Free AG." Stereo provides high-fidelity audio (44.1kHz+). Hands-Free drops the quality to 8kHz, which destroys the therapy filters. Always ensure your OS output is set to the Stereo profile.
• Latency: Bluetooth has inherent delay. If using Bimodal Haptics (Lenire module), use wired headphones for the most precise synchronization between sound and vibration.

2. Audio "Ducking" & Volume Fluctuations

• Notifications: When your phone or PC receives a notification, it often "ducks" (lowers) the volume of other apps. This disrupts the Mixing Point. Enable Do Not Disturb or Focus Mode during therapy sessions.
• Normalization: Features like "Loudness Equalization" or "Sound Normalization" in Windows/macOS attempt to make all sounds the same volume. This will fight against the suite's calibrated output. Disable these in your System Sound settings.

3. Hardware Phase & Stereo Image

• Centered Image: If the In-Phase tone in the System Validation tool sounds "wide" or "hollow" instead of centered, your headphones may be wired incorrectly or you are using Virtual Surround Sound.
• Action: Disable 7.1 Surround, Dolby Atmos, or Windows Sonic while using the suite. These features introduce phase shifts that invalidate Decorrelation and Binaural therapies.

4. Browser Permission Blocks

• Autoplay: Browsers prevent sites from playing audio automatically. If you don't hear sound, click anywhere on the page to "resume" the audio context.
• Tab Throttling: If audio stops when you switch tabs, ensure you have the suite installed as a PWA (Add to Home Screen) or keep the tab visible. The built-in Audio Watchdog attempts to recover from these stalls automatically.

Clinicians may use this form to establish a baseline for new patients entering an auditory habituation program. Patients should complete this prior to their initial consultation.

Habituation is a gradual process. Use this tracker to identify your progress through the typical stages of auditory retraining. Note that progress is rarely linear; "spikes" are a normal part of the journey.

Below are mockups of the various clinical exports available in the suite. These samples help you understand how your data is presented to healthcare providers.

1. Clinical PDF Report Mockup

2. Email-to-Clinician Sample

3. Raw Data Export (.txt)

• Pink Noise: A sound spectrum where every octave contains equal energy. Preferred for therapy as it mirrors natural acoustic distributions.
• Brown Noise: Higher energy at lower frequencies (bass heavy). Often perceived as "warmer" or "softer" than White noise.
• Carrier Frequency: The main "test tone" or audio signal that is being processed or modulated by another signal.
• Amplitude Modulation (AM): The systematic variation of volume over time, used in bimodal therapy to increase signal saliency.
• LFO (Low Frequency Oscillator): A slow-moving signal (0.1Hz - 20Hz) used to control parameters like volume or filter sweeps.
• Logarithmic Scale: A non-linear scale where equal distances represent equal ratios (e.g., octaves), matching how the human ear perceives pitch.

Precise neuromodulation requires linear frequency response and high signal-to-noise ratios. Below are recommended hardware standards:

1. Headphones

• Preferred: Wired, Over-Ear, Open-Back (e.g., Sennheiser HD600 series, Beyerdynamic DT880/990). Open-back models provide superior spatial imaging for Decorrelation.
• Secondary: High-quality wired IEMs (In-Ear Monitors).
• Avoid: Noise-canceling headphones (ANC) during calibration, as their internal DSP can alter the phase of the therapy signal.

2. Audio Interfaces (DACs)

• Standard laptop/smartphone jacks are usually sufficient. For desktop users, a simple external USB DAC (like the Apple USB-C Dongle) provides a cleaner floor for high-frequency testing.

3. Mobile Considerations

• Use wired connections where possible to eliminate the 150ms-300ms latency inherent in Bluetooth, which can desynchronize Bimodal Haptics.
