The human ear is an astounding transducer, converting sound energy to mechanical energy to a nerve impulse that is transmitted to the brain. The ear's ability to do this allows us to perceive the pitch of sounds by detection of the wave's frequencies, the loudness of sound by detection of the wave's amplitude, and the timbre of the sound by the ...

Learn about the structure of the ear and what sounds we can and cannot hear and the different uses we have for sound, including ultrasound, in this guide for KS3 physics students aged 11-14...
Normal human hearing encompasses frequencies from 20 to 20,000 Hz, an impressive range. Sounds below 20 Hz are called infrasound, whereas those above 20,000 Hz are ultrasound. Neither is perceived by the ear, although infrasound can sometimes be felt as vibrations.
Key words about the human ear and hearing. Outer ear - Part of the ear you can see. Shaped like a funnel to collect sound waves and send them to the inner ear. Also called the pinna. Ear canal...
The purpose of the external ear is to transmit sounds from the outside world into the more internal parts of the auditory system. While one can simply think of the pinna and ear canal as a simple funnel for collecting sounds, in reality they perform some important functions.
The human ear has a tremendous range and sensitivity. It can give us a wealth of simple information—such as pitch, loudness, and direction. And from its input we can detect musical quality and nuances of voiced emotion.
