3
Q
Bulk modulus
A
A material’s resistance to compression
4
Q
Frequency
A
High= high pitched low= low pitched
5
Q
Intensity
A
Amplitude squared is proportional to intensity
- decible scale
- 10log of I/I0 is unitless
6
Q
When intensity of sound drops over a distance
A
Attenuation or sound dampening
7
