Flashcards in 15 Deck (13):
1

What are the factors that affect threshold audibility?

Sound frequency
Listening field
Sound duration

2

Better thresholds are in _ frequencies

Mid

3

What are the listening fields?

Headphones
Earphones
Free field

4

Sound duration is also called:

Temporal integration

5

MAF uses:

Sound field

6

MAP uses:

Headphone

7

There is a _ dB difference between the MAF and MAP

6dB

8

What is the average LDL?

100-120dB

9

_ determines the shape of the minimum audibility curve

ME transfer function

10

What is JND?

Just noticeable difference
The amount something must be changed in order for a difference to be detectable 50% of the time

11

What is Weber's law?

*f/f = k
*f represents difference threshold
f represents initial stimulus frequency
k represents the constant

12

Weber's law holds to what frequencies?

400 - 2000 Hz

13

Example of Weber's law:

k = 0.0015
f = 1000
therefore
*f/1,000 = 0.0015
*f = 0.0015
