Hearing and Listening


1	An audibility function measures
		A)	perceived loudness as a function of physical intensity.
		B)	threshold intensity as a function of frequency.
		C)	perceived pitch as a function of frequency.
		D)	threshold changes in the component frequencies of complex stimuli.


2	Audibility functions
		A)	do not change as one ages.
		B)	are highly variable across individuals.
		C)	are very good diagnostics for central auditory system disorders.
		D)	can be affected by exposure to loud sounds.


3	Which of these sources of hearing impairments is incorrectly matched with its category?
		A)	build up of ear wax; conduction loss
		B)	presbycusis; sensorial/neural
		C)	otosclerosis; conduction loss
		D)	exposure to noise; conduction loss


4	A transitory reduction in hearing sensitivity following noise exposure is called
		A)	tinnitus.
		B)	temporary threshold shifts.
		C)	otosclerosis.
		D)	phonagnosia.


5	Tinnitus can be temporarily induced
		A)	by smoking.
		B)	by jogging.
		C)	by taking aspirin.
		D)	by consuming salt.


6	If a person has a hearing impairment in the higher frequency range, which of these speech sounds will be the hardest to hear?
		A)	/oo/
		B)	/m/
		C)	/ay/
		D)	/f/


7	Which of these statements is not a criticism of cochlear implants?
		A)	The technology is still at an early stage.
		B)	It could isolate the individual from the deaf community.
		C)	They don't fully restore normal hearing.
		D)	They are unable to achieve even modest levels of speech recognition.


8	The range of frequencies that are audible to an animal
		A)	is shifted toward higher frequencies the smaller the animal.
		B)	are the same across species.
		C)	is wider the smaller the animal.
		D)	are all wider than the range audible to humans.


9	The auditory phenomenon where a background noise makes a weak sound more difficult to hear is known as

		C)	masking.
		D)	diminishing.


10	Band pass noise can vary in
		A)	bandwidth.
		B)	center frequency.

		D)	all of the above.


11	As you increase the bandwidth of band pass noise centered on a frequency, you are trying to detect whether the threshold intensity for that frequency
		A)	steadily increases.
		B)	steadily decreases.
		C)	increases, then remains constant.
		D)	decreases, then remains constant.


12	The limited portion of the energy in broadband noise that is effective in masking a tone is termed a
		A)	critical band.
		B)	relative bandwidth.
		C)	masking range.
		D)	auditory profile.


13	The perceived loudness of a sound is influenced by
		A)	signal intensity.
		B)	signal frequency.
		C)	signal phase.
		D)	both a and b.


14	The ability to detect the change in the intensity of a tone relative to other tones is called
		A)	magnitude estimation.
		B)	the McGurk effect.
		C)	profile analysis.
		D)	loudness matching.


15	The phenomenon of perceiving the missing fundamental is due to the presence of
		A)	perfect pitches.
