|
Term
|
Definition
| when you dont want sound 'spilling' over into the non testing ear |
|
|
Term
| when do you need to use masking? |
|
Definition
| if the difference between two ears (air conduction) is 40 dB or more |
|
|
Term
|

Term
| 40 dB is considered the _______ rate for masking |
|
Definition
|
|
Term
| "as sounds travel from one side of the head to the other, a certain amount of energy is lost in transmission. this loss of intensity of a sound introduced to one ear and heard by the other called ______ |
|
Definition
|
|
Term
| interaural attentuation is the dB HL above whih sound can? |
|
Definition
| cross from one side of the head to the other when testing hearing sentivity |

as soon as we start to test a worse ear by bone conduction, we know that hte better ear is going to respong unless we add some masking noise |
|
Definition
|
|
Term
three types of masking noise?
|
|
Definition
-broadband noise (white noise)
-pink noise (speech weighted noise)
-narrow badn noise |

|
Definition
|
|
Term
