Acoustic neuromodulation

Explore a conservative multi-tone coordinated-reset style sound pattern.

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.

Reference frequency 4,000 HzThe highest generated tone is 1.4× the reference and remains below the 12 kHz default ceiling.

Research-reference sequence

Four tones at 0.766×, 0.9×, 1.1×, and 1.4× the reference; 150 ms each; 1.5 cycles/second; three active cycles followed by two silent cycles. Tone order is deterministically shuffled.

Audio duration

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.

RESET2 double-blind trialThe device was not superior to placebo on the primary outcome; this is a key reason the tool is experimental.
