CSD: Speech and Hearing Science- Chpt. 1, 8, & 9 Test

Energy

ability to do work

elasticity

property of a material that returns it to its orginal shape

power

rate of work done or energy used in a period of time

speed

distance traveled at any given time

pressure

force acting on a specific surface are

velocity

distance traveled in a given unit of time in a specific direction

volume

quantity of a 3D space occupied

mass

amount of matter in an object

force

any influence that causes an object to undergo a change in speed, direction, or shape

scientific measurement systems are based on __________ system

metric

the main function of this part of the ear is to help channel sound waves in the ear canal

outer ear

a type A tympanogram indicates

normal middle ear function

This part of the inner ear is important for hearing

cochlea

a sound with one single frequency

pure tone

individuals with high-frequency hearing loss have particularly have difficulty perceiving

consonants

what type of tympanogram is this and what would it typically suggest

• abnormal type B

• suggests very little or no movement of the tympanic membrane

• could be caused by pressure in the middle ear or cerumen preventing a proper test

Amplitude corresponds to loudness and frequency corresponds to pitch (T/F)

true

an electronic device designed to directly stimulate the auditory nerve and is typically used for persons with severe to profound sensorineural hearing loss

cochlear implant

diagnostic test of the middle ear system

tympanogram

what is the unit of measurement for frequency

hertz

What separates the outer and middle ear

tympanic membrane

What is an otoacoustic emission (OAE) and what type of patient demographic might we use this test for? What is the difference between how an audiologist might use this test vs. how a speech language pathologist might use this test?

• OAE measures the sounds the inner ear, specifically the cochlea, sends back through the ossicles

• can be used on any patient as the patient does not need to be conscious

  • most likely used on someone suspected of severe hearing loss to show whether the inner and middle parts of the ear are working correctly

• Audiologist: see where damage could be

• SLP: extent of hearing damage and how this could affect speech perception or production

length of time it takes to complete one cycle of a vibration

period

the semicircular canals and vestibule are important for

balance

tympanometry tests three main properties of the middle ear…

• pressure

• compliance

• volume

what does Eustachian tube do?

• keeps middle ear space ventilated

• equalizes pressure between middle ear and atmosphere

• runs from the nasopharynx into the middle ear

Threshold

the maximum or minimum frequency of a sound a person can hear at a certain amplitude

if someone has normal tympanometry results, we cannot assume that they have normal hearing (T/F)

true

a combination of biology and acoustics in the study of sound production and perception in animals including humans

bioacoustics

know where malleus, pinna/auricle, tympanic membrane, cochlea, eustachian tube/auditory tube, semicircular canals, stapes, and incus are on diagram

four major parts of the auditory system

• outer ear

• middle ear

• inner ear

• auditory nerve

three types of hearing loss

• conductive

• sensorineural

• mixed

graph that represents an individual’s hearing threshold at selcted frequencies

audiogram

on an audiogram hearing loss is documented by

decibels and frequency

This test is one of the objective hearing measures discussed in class. It uses electrodes to measure the response from the 8th cranial nerve

auditory brainstem response (ABR)

Which of the following statements is NOT true of otitis media?

• can result from upper respiratory infection

• can result from build-up in the middle ear

• common in young children

• results in a mixed hearing loss

results in a mixed hearing loss

What type of tympanogram is this and what would it typically suggest

• abnormal type C

• suggests extremely negative pressure in the middle ear

• primarily caused by stiffening of the ossicles
