Answer 2

Absolute sensitivity

Differential sensitivity

Question 3

the capacity of the auditory system to detect FAINT sounds

Answer 3

Absolute sensitivity

Question 4

the capacity of the auditory system to detect DIFFERENCES or CHANGES in Intensity, Frequency or some other dimension of sound

Answer 4

Differential sensitivity

Question 5

most commonly refers to absolute sensitivity to faint sound.

Answer 5

Hearing sensitivity.Hearing sensitivity is expressed as the number of Decibels above (or below) the average normal-hearing person’s thresholds fro different puretones (0db HL)

Question 6

most accurately to the differential sensitivity , the ability to detect differences in signals that differ in the Frequency domain

Answer 6

Hearing Acuity

Question 7

the level at which a stimulus or change in stimulus is just sufficient to produce a sensation or effect

Answer 7

Threshold

Question 8

the intensity at which a tone is barely audible

Answer 8

Hearing Threshold

Question 9

represents hearing sensitivity as a function of signal frequency.

Answer 9

Minimum audibility curve

Question 10

The Minimum Audibility Curve serves as the basis for pure-tone audiometry and the curve is converted into a graph known as
