Question

Higher-pitched sounds have ___.

0 A.) higher amplitudes
0 B.) shorter wavelengths
0 C.) mode decibels
0 D.) lower frequencies

Answer 1

c

Step-by-step explanation:

Answer 2

The answer would be c.

The decibel level of a sound having the threshold intensity of 10−12 W/m2 is β = 0 dB, because log101 = 0. That is, the threshold of hearing is 0 decibels. Table 1 gives levels in decibels and intensities in watts per meter squared for some familiar sounds.
