Notched sound generator

Create noise with a smooth frequency band reduced around a chosen centre frequency.

Start quietLower device volume first. Stop if uncomfortable.

Safety check before sound

Do not continue here—seek urgent care for tinnitus with sudden hearing loss, new facial weakness or other neurologic symptoms, severe sudden vertigo, or tinnitus after a head injury. Arrange clinical assessment for a heartbeat-synchronous sound or persistent new one-sided or asymmetric tinnitus.

I have lowered my device volume, none of the urgent warning signs applies, and I will stop if uncomfortable.

Audio duration

Prefer WAV for the notched sound. MP3 is lossy and this release does not decode and re-verify the notch after encoding, so the compressed file may alter the intended spectral reduction.

Reports and audio are created locally. Shared settings are stored after # in the URL and are not included in the web request. MP3 is a lossy format; WAV preserves the locally rendered PCM.

Sources and limits

Clinical cautions follow the NICE tinnitus guideline and safe-listening advice follows the World Health Organization. Tool-specific research is summarized below and in the downloaded report; a reference does not mean that a generated sound has proven therapeutic benefit.

2024 systematic review and meta-analysisNotched music did not significantly outperform ordinary music for tinnitus distress.
2025 systematic review and meta-analysisReported possible benefits across small heterogeneous studies; the conflict reinforces that efficacy remains uncertain.
