Physics and Audio Perception

20Hz-20kHz

Decibels

Hertz

340-343 meters per second

Created the theory of amplitude, frequency, and wavelength

sine wave

All notes have a most basic (fundamental) tone, with harmonics overtop

Describes the intensity of a sound from a certain distance from the original starting point (S/4pi^2=I)

Outer ear (part we can see)

Connects to pinna, where audio from outside goes into

Eardrum

the bone attached to the eardrum (think MIS)

Middle ear bone (Think MIS)

Transmits sound from incus to cochlea (Think MIS)

The part the Stapes connects to

Loops at the top of the ear (above cochlea)

the snail-shaped tube where sound vibrations are converted into nerve impulses by the organ of Corti

connects to the cochlea and brings sound to the brain

above cochlear nerve

Little hole next to cochlea, one of the connections from the middle ear to inner ear

second tube in the deep ear

Loudness level contours

electric current is directly proportional to voltage and inversely proportional to resistance (V=IR)

(wavelength=velocity/frequency) calculates wavelength
