Yes. Loud noise can cause a person to go deaf
Ultrasound.
Vibrations are perceived by the human ear as sound. Faster vibrations produce higher-pitched sounds, while slower vibrations sound lower-pitched.

Adults cannot hear if there is a very high pitched ringing sound, but kids can hear it. +++ Sort of. Some adults may be able to hear the same high-pitched sounds as children. More accurately, the healthy ear can detect sound up to about 20kHz, but age and long-term noise exposure reduce the maximum an individual can hear.
It is due to the sensitive hairs found in your ear. This causes noises to vibrate, where we are able to hear them. As we age, are hairs lose their once youthful strength, and some high pitched noises are difficult to hear.
Slower than at a high pitched sound
That high pitched noise is probably a warning signal. You probably put the batteries in backwards or put in the wrong kind of batteries. make sure they're the right type and all oriented properly.
It's a part of the "transducer" that converts air sounds (large, low pressure) into liquid sounds (low amplitude, high pressure) - it connects the ear drum to the inner ear (a thin section of the skull.
Outer ear
No, you have problems to hear the TV when you have listened too loudly and too much to your ear phones. mostly most people cant, but i can and nobody believes that i hear high pitched sounds that other people cant hear...so ur not alone
Bats use echolocation to sense movement and their surroundings. We cannot hear the high pitched noise they emit because it is of a higher frequency than the human ear can register. There are some sounds of a bat that we can hear, but the sounds that we can't hear is because the squeaks are so high that you really need ultrasound to hear it.
Ultrasound simply means that the sound is too high-pitched for the human ear to pick it up.
