hearing

ch 9

what does amplitude refer to

measured sound pressure levels, also termed as intensity

what is the perception of amplitude referred to as

loudness

what is the perception of amplitude, termed loudness, expressed with

decibels (dB)

what is frequency measured in

hertz (Hz)

what is the term used when referring to the perception of frequency

pitch

what does loudness refer to

the subjective experience of the pressure lvls of a sound

what is decibel (dB) the measurement of

sound intensity (amplitude)

what is hertz (Hz) or cycles per seconds the measurement of

frequency

what does pitch refer to

the DIMENSION/DEPTH of auditory exp in which sounds may vary from low to high

what is the Fourier analysis

mathematical (algebraic) process of a complex pattern into a sum of sine waves of various frequencies and amplitudes.

what is the perception of frequency referred to as

pitch

what does the middle ear consist of

the taut tympanic membrane (eardrum)

what can the taut tympanic membrane also be referred to as

the eardrum

what does the middle ear do

seals the end of the ear canal where ossicles that mechanically couple the tympanic membrane to the inner ear at the oval window

what do soundwaves in the air strike when processing hearing

the tympanic membrane

what do sound waves in the air strike

the tympanic membrane

when soundwaves strike the tympanic membrane what occurs

tympanic membrane vibrates w same frequency as sound

what does the movement of the tympanic membrane cause when sound waves move the chain of ossicles

concentration of tiny mechanical forces of vibration from air particles captured from the large tympanic membrane

what arrangement amplifies sound pressure so that it can produce movement in the fluid of the inner ear

movement od the tympanic membrane

what does the inner ear refer to structure wise

The cochlea and vestibular apparatus

what is the function of the inner ear

works to convert sound into neural acti\vity

what is the auditory portion of the inner ear is a coiled, fluid-filled structure?

the cochlea

what does the middle ear refer to structure wise

cavity between the tympanic membrane and the cochlea

what is the other name for the tympanic membrane

eardrum

what is the tympanic membrane

the division between the external ear and middle ear

what are the ossicles

the three small bones that transmit sound across the middle ear—from the tympanic membrane to the oval window

what is the oval window

the location on the surface of the cochlea where vibrations are received from the ossicles.

what are the ossicle bones called

malleus, the incus, and the stapes

_____ mechanically couples the tympanic membrane to the inner ear at the oval window

what do sound waves strike in which they cause the structure to vibrate with the frequency as the sound

the tympanic membrane

what does the movement of the tympanic membrane cause the movement of within the middle ear

the movement of the chain of ossicles

what does the movement of the chain of ossicles result in

the concentration of the tiny mechanical forces of vibrating air particle from tympanic membrane to the oval window—amplifying sound pressure

what does the amplification of sound pressure allow for

the movement in the fluid of the inner ear

what does the cochlea convert vibrational energy into

“waves of fluid” better said as neural activity!

what does the cochlea contain the cells of

the primary receptor cells for hearing
