auditory system can actually perceive the beat of the music so that's why okay so as I said before the ear is capable of representing or perceiving loud average or soft sounds as well as different frequencies so the human ear can perceive from 20 Hertz to 20,000 Hertz and just to give you a point of reference bats can hear up to about 70,000 Hertz which is why they use echolocation dogs can hear up to about 40 or 50,000 Hertz

much broader than ours but as I said the the cochlea is able to break down all of these frequencies and you know speech is a complex sound complex sound is a sound that's made up of many frequencies and so our ears are able to perceive speech and again make use of that sound which is what we need to communicate in addition the ears play off of one another and the brain compares input from both ears in order
