How does a sine wave happen in ur ear? happens to me now and again? Is it normal? normally goes in a few secs?

Answer 1

I am an MD. I believe you are referring to the perception of a single tone in your ear, that seems to come at random, right? As we are taught, this is a sign of hearing loss. Every time you hear it, you are undergoing a tiny amount of hearing loss. As you get older, the total sum of these hearing losses adds up to a significant amount, to the great pleasure of the hearing aid manufacturing industry. Some believe it is a normal part of aging. Others disagree, citing studies of older humans who have lived all of their lives in a stone age existence, away from technology, who rarely if ever develop any hearing loss whatsoever. I hope this helps.

Sound represents a combination of waves that are generated by a vibrating sound source (or sources) and propagated through the air until they reach the ear. The most elementary sound wave is the sinusoid, or sine wave, which is produced by the regular to-and-fro vibration of the sound source. The sine wave can be characterized by several properties, the most important of which are its frequency and amplitude.
