Disclaimer & Safety Notice
These sound generators are provided for education, meditation and personal sound exploration. They are not medical devices and are not intended to diagnose, treat, cure or prevent any physical or mental-health condition. They are not a substitute for professional medical advice, diagnosis or treatment.
Use the generators only in a safe setting. Do not listen while driving, cycling, operating machinery, crossing roads or doing anything else that requires your full attention.
Begin at a low, comfortable volume and keep your first session short. Listening safety is affected by both volume and duration, so take regular breaks and avoid raising the volume to overpower background noise.
Stop listening immediately if you experience ear pain or pressure, dizziness, nausea, headache, agitation, disorientation, changes in hearing or increased ringing in the ears. Seek appropriate medical or audiological advice if symptoms persist or return.
If you experience tinnitus, hyperacusis, hearing loss, migraines, epilepsy, seizures or sensitivity to rhythmic sound, approach these tools with additional care and seek professional guidance when uncertain. If you know that particular sounds, music or rhythms can trigger seizures, do not use rhythmic sound generators without advice from your clinician.
Where a generator offers binaural beats, stereo headphones are required to hear the intended effect. Pure tones, isochronic tones and amplitude-modulated sounds can generally be played through speakers or headphones.
Your response to sound is personal. Choose only tones and listening methods that feel comfortable, and stop whenever a practice does not feel right for you.
