SPA3030 Exam 4 Review

When using the method of constant stimuli to find a patient's auditory threshold (indicate ALL that apply)

-the tester controls the stimulus -threshold is calculated as the softest level at which the patient correctly responds to 50% of the stimuli -the patient indicates if they hear a sound or not

Which of the following statement are true about an Equal Loudness Contour?

It denotes the level at which sounds are equal in perceived loudness

The experimenter presents a pair of tones. The listener describes the relationship of the loudness of the two tones in terms of a fraction or multiple. This is called

Ratio estimation

Which of the following statements is NOT TRUE about a critical band?

The critical band is the shortest period of silence, or gap, that can be detected between two bursts of narrow band noise.

_____ states that the size difference you can detect between two stimuli is proportional to the value of the stimuli to begin with

Weber fraction

Which of the following is true of cross-modality matching?

a visual stimulus can be compared to an auditory stimulus

Which of the following is a physical characteristic of sound?

amplitude

For every ten-fold increase in duration, the threshold for a sound______________.

decreases by 10 dB

Which of the following is true of minimum audible field?

it measures thresholds in both ears at once

Temporal summation refers to the fact that sound duration trades with sound intensity for sounds ____________________.

less than 300 ms

A very short tone of about 5 ms will be _______________

like a click

The phon is a measure of

loudness

A 1000 Hz 70 dB SPL tone is presented to an individual. They are instructed to change the frequency of the tone until they just notice a change in pitch. They change the tone to 1090 Hz and say they can just detect a change. If the change is noted as 90 Hz, then the measurement taken was a _____________________.

loudness difference

Which classical measurement method is most similar to how audiologists measure patient's thresholds in the hearing clinic?

method of limits

The mel is a unit of ____________

pitch

Which of the following techniques is being used, if an individual is asked to adjust a dial until the sound is three times louder than another sound.

ratio production

Periodicity pitch states that a pulse train will be perceived to have a pitch the same as the ___________________.

repetition rate of the pulses

Which of the following describes loudness adaptation?

the longer the duration of a sound, the less loud the sound is perceived

Psychoacoustics is the part of hearing science that deals with

the perception of acoustic sound stimuli

Which of the following correctly describes differential thresholds?

the smallest difference between two sounds that an individual can detect
