Prolonged exposure to high-decibel sounds can damage the inner ear in a number of ways, causing hearing loss. Higher frequencies are less detectable, so they're the first to go. For more info, see the link below.
Probably Because They Are Always Playing Such Loud Music
So they can hear themselves sing and play, which is almost impossible to hear due to the crowd noise and the unique amplified and mixed sound that is being heard by the audience. Often due to behind the scenes mixers, a performer can get confused by what they are doing in comparison to the behind the scenes mix that is bring produced for the audience. Simply put, they hear thru their earpiece the raw music they themselves are producing before electronics gets hold of it.
Yes, they wear them ... singers and instrumentalists in a band need to hear the other members so that keep the same tempo and thus be able to blend their voices with the others. Over the powerful amps and crowds they couldn't hear themselves singing without these aids.
A sound that characters in the scene might hear, such as the voices of people that we see, or the sound of music when we see the musicians (or reasonably expect that they are in the scene) like the music playing at a club.A voice that comes from an unseen source, like a narration or musical underscore, is non-diegetic sound.
Binaural beats are are a study and science into the patterns of brainwaves from giving pulsating sound though to calm a person and give a aura of well being. Unlike subliminal messaging it's thought to entertain the brainwaves making a person more subtle.
Absolutely. It is one of the major reasons of rock musicians suffering from hearing loss.
i tones because there was no way to hear tones
They obviously don't
Bacause they can't
Yes, pigs can hear tones from about 40 Hz up to 40KHz. See related link.
Clairvoyance is the ability to see that which is unseen, such as in the future. Clairaudience is the ability to hear that which others do not hear.
because their ears are more developed.
SHE ASKED HIM to speak to the Indians so she could hear his tone
You hear 'beats', or pulses, and these pulses happen at a frequency which is the difference between the frequencies of the nearly identical tones.
cicdas do not have the ability to hear sounds
Yes, they can. They have the ability to hear the heartbeat of a mouse, so a human heart wouldn't be a problem for them to hear.
