Acoustics Chapter 2

Shelters the eardrum by maintaining constant temperature and humidity and prevents the accumulation of dirt and foreign matter

Not extremely important in humans, but aids in location and intensity judgments.

Delicate bones which transmit vibrations without distortion and increase mechanical efficiency by leverage and area-of-force advantage.

Vibrations of this structure cause a sliding, shearing force on the hair cells attached to the tectorial membrane.

Location of the first systematic connection of the auditory system with the central nervous system.

Serves to equalize air pressure on each side of the eardrum.

Responds to pressure variations of air and converts these into mechanical vibrations.

Actions of these minute structures transduce mechanical energy into electro-chemical impulses.

The entrance to the cochlea and semi-circular canals.

Regulates body orientation in space and the sense of balance.

Connects the auditory sensory receptors with the central nervous system

Transmits vibrations to the oval window of the vestibule.

Acoustical energy is transformed into mechanical energy in the

In order to reach the sensory receptors for hearing, sound must travel medially through the

Contains the sensory receptors of hearing

The action which transforms mechanical energy into neural impulses stimulates the fibers of the

The differential stimulation of the of the hair cells along the basilar membrane of tones of varying frequency is referred to as the

The smallest increment of certain properties of musical sound which will permit the hearer to perceive a change in the stimulus is referred to in psychoacoustical terms as

If a friend of client complains of a ringing in their ears, you should send them to

A disease in which bony growths inhibit the mechanical operation of the ossicles is

The perception of differences between consonance and dissonance is mainly

By using the "mystical" ratio of 3:2, the Greeks developed a musical temperament called

The three ossicles of the middle ear are individually known as the

Shaped like a snail shell, the cochlea contains a partition section and two parallel circular pathways; an upper region called __________ and a lower region known as __________

The space between two neurons in the same neural pathway is called a
