How do I find my tinnitus frequency?

Play a tone and adjust its pitch until it sits as close as possible to your tinnitus, then refine in small steps. Always run an octave-confusion check (compare the match against tones one octave above and below) because octave errors are the most common mistake.

Why does matching the exact frequency matter so much?

Frequency-targeted therapies (notched noise, ACRN) act on the neural region corresponding to your tinnitus pitch. If the match is an octave or more off, the therapy works on the wrong part of the tonotopic map and is far less effective.

What is octave confusion in pitch matching?

Many people with tinnitus match their tone an octave (or two) away from the true pitch because octaves sound perceptually similar. A deliberate octave-comparison step during calibration catches this.

Can my tinnitus frequency change over time?

It can drift, especially after noise exposure or with hearing changes. Re-checking your pitch match every few weeks, and validating it with a brief residual-inhibition test, keeps therapy accurate.

What is residual inhibition and how does it validate my frequency?

Residual inhibition is a brief, temporary reduction of tinnitus after listening to a matched sound. If a sound centred on your matched frequency produces noticeable short-term quieting, it is good evidence the match is accurate.

How to Find Your Tinnitus Frequency — And Why Precision Changes Everything

Every evidence-based tinnitus therapy — notched sound, ACRN, bimodal stimulation — depends on one number: the frequency of your tinnitus in Hertz. A 500 Hz error doesn’t just reduce effectiveness. It can, in some cases, eliminate it entirely. Here is how to calibrate accurately and why the standard methods often fail.

Why Frequency Accuracy Matters So Much

The mechanism of notched sound therapy — lateral inhibition targeting the exact neuronal population generating the tinnitus — is highly frequency-specific. Studies using MEG neuroimaging have shown that the reduction in cortical activity produced by notched sound therapy is localised to a band approximately ±0.5 octaves around the notch centre. Outside this band, the effect falls off sharply.

A study by Reavis et al. (2014) quantified this directly: at ±0.5 octave error, the inhibitory effect was reduced by approximately 60%. At ±1 octave error, no statistically significant effect was measurable. For ACRN, which uses four precisely ratioed tones, calibration error directly mismaps the tone frequencies relative to the optimal desynchronisation targets, with similar consequences.

The Precision Requirement

Most therapies need calibration within ±0.3 octaves (~25%) of the true tinnitus frequency to show measurable benefit. For a 7,000 Hz tinnitus, this means staying within the 5,600–8,750 Hz range.

Why Pitch Matching Is Harder Than It Sounds

Tinnitus pitch matching is surprisingly difficult, and the standard clinical audiometric pitch match has known reliability limitations. Several factors make it challenging:

1. The audiometric dead zone

Tinnitus most commonly occurs at the edge of, or within, a hearing loss region. The neurons responsible for hearing at the tinnitus frequency may be significantly damaged, making it hard to compare external tones to the internal tinnitus signal with any precision.

2. Octave confusion

This is the most common matching error. Many people match their tinnitus to a frequency exactly one octave below its actual pitch. A 7,000 Hz tinnitus might be reported as 3,500 Hz. This occurs because the harmonic relationship between octaves makes them perceptually similar, especially when comparing an internal sound to an external one across a damaged cochlea.

3. Tinnitus is not a pure tone

Many people have tinnitus that is narrowband noise, a complex tone, or multiple simultaneous tones. Trying to match this to a single pure tone introduces inherent imprecision. The practical approach is to match to the most prominent component.

4. The contralateral pitch match problem

In unilateral tinnitus, the test tone should ideally be presented to the opposite ear from the tinnitus, to avoid acoustic interactions. In bilateral tinnitus, the comparison is more complex.

The Step-by-Step Pitch Matching Method

This is the method Tinnitus Wizard uses, adapted from the Müller-Wehlau and modified bracketing protocols:

Eliminate external sound. Use a quiet room or headphones. Background noise competes with the matching tone and reduces accuracy significantly.
Start with a wide sweep. Play a tone that sweeps slowly from 4,000 Hz to 12,000 Hz. Note the approximate range where it most resembles your tinnitus.
Bracket from above and below. Set a tone 1 octave above where you think your tinnitus is. Does it sound higher or lower than your tinnitus? Step down. Repeat, bracketing from both sides until you have a range of ±500 Hz.
Fine tune in 50 Hz steps. Within the narrow range, alternate between tones 50 Hz apart. Which sounds more like your tinnitus? Move in that direction.
Octave check. Once you have a candidate frequency, play the same tone one octave lower. Does that match better? If yes, your initial match was an octave error — use the lower frequency.
Loudness match. Once frequency is set, adjust volume until the test tone matches the perceived loudness of your tinnitus. This is the Minimum Masking Level — important for calibrating therapy volume.
Repeat on a different day. Run the calibration twice on separate days and average the results if they differ by more than 200 Hz.

Common Errors and How to Avoid Them

Error	How to Detect	Fix
Octave confusion (matched one octave low)	Your match is below 4,000 Hz despite experiencing high-pitched tinnitus	Run the octave check; try the match at double the frequency
Matching to hearing threshold, not tinnitus	Match shifts with volume changes	Match at a fixed moderate volume; the “right” frequency should be obvious regardless of volume
Inconsistency between sessions	Matches differ by >500 Hz across days	Average 3+ sessions; tinnitus does genuinely fluctuate somewhat
Matching to a harmonic	Multiple candidate frequencies all “fit”	Test each candidate for 2 minutes of therapy; the correct one often produces brief post-session suppression (residual inhibition)

How Tinnitus Wizard Calibration Works

The Calibrate tab in Tinnitus Wizard implements a guided bracketing protocol:

A frequency slider covering the 4,000–11,000 Hz therapeutic range
Fine adjustment buttons (±50 Hz, ±100 Hz) for precision tuning
Live tone playback with warble mode option (helps some people match to narrow-band tinnitus)
A “Save Pitch” function to record multiple candidate frequencies
The Residual Inhibition test, which validates the chosen frequency: a 60-second narrow-band masker at the selected frequency should produce brief post-session suppression if the match is correct
The notch visualiser shows the exact spectral notch your therapy will apply

Validation Tip: Use the RI Test

After pitch matching, run the Residual Inhibition test. If you experience even brief (5–30 second) quieting of tinnitus afterwards, your frequency match is in the correct range. No effect may indicate an octave error.

Tinnitus Frequency Drift Over Time

Tinnitus pitch is not fixed. Several studies have documented systematic frequency changes over months, particularly during sound therapy. This makes sense mechanistically: as lateral inhibition therapy progressively suppresses neural activity at the tinnitus frequency, the “centre of gravity” of the tinnitus-generating neural population can shift slightly.

Practically, this means recalibrating every 4–6 weeks, especially if you notice your therapy seems less effective than it did initially. Tinnitus Wizard prompts a re-run of the Setup Wizard periodically to maintain calibration accuracy.

Key Takeaways

Frequency calibration accuracy directly determines therapy effectiveness. A >0.5 octave error reduces the inhibitory effect by ~60% or more.
Octave confusion is the most common matching error: people often match one octave below their actual tinnitus pitch.
The step-by-step bracketing protocol — wide sweep, bracket, fine-tune, octave check — is significantly more accurate than a single-attempt match.
Validate your frequency using the Residual Inhibition test: brief post-session quieting confirms you’re in the right range.
Recalibrate every 4–6 weeks; tinnitus frequency drifts over time, especially during active therapy.
