Dogs, cats, dolphins, bats, and mice can hear ultrasound.
The maximum upper range of human hearing is about 20 kHz, for dogs about 45 kHz, and for cats, about 64 kHz.
Exposure to loud noises or music thins the protective coat of myelin around the auditory nerve, resulting in hearing loss.
The word "listen" has the same letters as the word "silent."
Hearing is the fastest human sense. A person can recognize a sound in as little as 0.05 seconds.
Because humans hear anywhere from 20 to 100 times faster than they see, everything that they perceive with their ears colors every other perception they have, and every conscious thought they have. Sound gets in so fast that it modifies all the other input and sets the stage for it.
The right ear is more efficient for listening to speech, while the left ear is better at listening to music.
