Central and Temporal Masking

Question 1

Explain when central masking would occur.

Answer 1

Central masking could occur when the target is in one ear and the masker is in the opposite ear.

Question 2

Explain when temporal masking would occur.

Answer 2

Temporal masking could occur when the target and the masker are presented sequentially. Forward masking = masker presented before the target. Backward masking = masker presented after the target.

Question 3

interaction in binaural auditory pathways

Answer 3

central masking

Question 4

more central masking occurs for _____ frequency tones than for ________

Answer 4

high, low

Question 5

When does the greatest amount of central masking occur?

Answer 5

when the masker and the test tones are closer together in frequency

Question 6

what is the common clinical threshold shift produced by central masking?

Answer 6

5-10 dB

Question 7

type of masking when the masker and test signal do not overlap in time

Answer 7

temporal masking

Question 8

two types of temporal masking

Answer 8

backward and forward masking

Question 9

why is forward masking important?

Answer 9

because a vowel can mask a consonant in running speech

Question 10

type of masking in the cochlea

Answer 10

psychoacoustic

Question 11

noise can mask important components of speech

Answer 11

psychoacoustic

Question 12

masking in the same ear

Answer 12

psychoacoustic

Question 13

masking happening in neural pathway with binaural auditory pathways

Answer 13

central

Question 14

noise in one ear can affect thresholds in the other ear

Answer 14

central

Question 15

happens in different ears

Answer 15

central

Question 16

happens in neural pathway and sounds of speech can mask subsequent consonants

Answer 16

temporal

Question 17

happens in the same ear

Answer 17

temporal

Question 18

backward masking

Answer 18

target then the masker

Question 19

forward masking

Answer 19

masker then the target
