If listening brings on a headache, dizziness, nausea or other discomfort, stop the audio and take the headphones off. You do not need to finish a session to find out whether it is useful.

Discomfort does not reveal the cause

A symptom occurring during a track does not tell us what caused it. Volume, headphone fit, the listening environment and unrelated health issues can all be relevant. Research has not established reliable rates or causes of binaural-beat side effects, and this website cannot diagnose them.

Claims that faster beats cause anxiety, that nature sounds prevent side effects, or that a particular carrier frequency is safer should not be presented as established facts.

Protect your hearing

Start with a low volume, take breaks and use your device’s sound-exposure or volume-limiting features if available. Do not turn a track up to force an effect. A sound feeling comfortable does not prove that prolonged exposure is safe. The World Health Organization’s safe-listening guidance explains how volume and duration work together.

When to get help

If dizziness continues, returns or worries you, seek medical advice rather than repeatedly testing a track. The NHS guidance on dizziness describes reasons to contact a clinician.

Sudden hearing loss needs urgent medical attention. Do not assume a new change in hearing is an expected response to a sound session. See the NHS hearing-loss guidance for urgent symptoms and next steps.

Existing conditions and personal advice

This site cannot provide clearance for a health condition or a medical device. If you have concerns about your hearing or about a particular listening experience, ask a clinician familiar with your circumstances. We do not publish blanket claims that ordinary audio is contraindicated in pregnancy or for people with pacemakers.

Avoid immersive listening when you need complete awareness of your surroundings, such as while driving. The previews on this website are intended for adults; they are not a treatment programme for children.

You can choose silence

A session is optional. If you dislike it or feel worse, you can stop without trying another frequency or completing a week of measurements. Personal comfort and preference are useful observations, not proof of a change in brain activity.
