Detailed explanation-1: -Audio is sound that is within the acoustic range of human hearing. It is the audible portion on the spectrum of sound frequencies, distinct from inaudible sounds heard by certain animals or used in science and medicine.
Detailed explanation-2: -People can hear sounds at frequencies from about 20 Hz to 20, 000 Hz, though we hear sounds best from 1, 000 Hz to 5, 000 Hz, where human speech is centered. Hearing loss may reduce the range of frequencies a person can hear. It is common for people to lose their ability to hear higher frequencies as they get older.
Detailed explanation-3: -When the eardrum moves, the three middle ear bones vibrate. This vibration creates movement of fluid in the inner ear also known as the cochlea. The fluid movement causes sensory receptors in the coiled shaped cochlea, to send a signal along the auditory nerve to the brain-and this is how we hear.
Detailed explanation-4: -This sound which we hear is called an echo.
