The discussion revolves around the potential use of destructive interference sound waves to treat tinnitus, a condition characterized by ringing in the ears. Participants explore the feasibility of using hearing aids to cancel out specific frequencies that only the patient can hear, and they express concerns about the medical approach to diagnosing and treating such symptoms.
Participants generally agree on the complexity of diagnosing tinnitus and the need for careful consideration of symptoms, but multiple competing views on the causes and treatment approaches remain unresolved.
Participants express uncertainty about the methodologies used in the medical field, including the adequacy of testing and the interpretation of symptoms. There is also a lack of consensus on the effectiveness of potential treatments and the nature of the underlying issues.
This discussion may be of interest to individuals experiencing tinnitus or similar auditory symptoms, as well as those interested in the intersection of engineering and medical approaches to treatment.
This is not only difficult (as pointed out by @russ_watters), but impossible. Noice cancelling technology relies on a microphone to continually monitor the incoming noice or signal, so an inverted signal can be created to cancel it. Since your ringing is not a real incoming audio wave, no device will be able to cancel it by destructive interference.erobz said:How difficult would it be to send destructive interference sound wave into an ear via hearing aid device, which cancels a ringing frequency/amplitude only I can hear.
Impossible would seem a bit strong? My brain is measuring it, or outputting it. Perhaps impossible with our current understanding of the brain and its signals, but if my brain is observing it must be observable directly/or indirectly? I can just say flat out, "that's the inverted frequency/amplitude" when I observe the absence of significant ringing. The trick would be to have that done actively. Like I said it doesn't vary in frequency (what I'm consciously measuring as the output at least), just amplitude with stress perhaps.Dali said:This is not only difficult (as pointed out by @russ_watters), but impossible.
