That value is the threshold of hearing.

2x to the fourth power minus 162 equals -146
49 - 8 - 6 = 35
4²-3+11-12 = 16-3+11-12 = 12
-68 I think
The standard unit of measurement for sound power is the decibel (dB). It is defined in relation to the intensity of sound waves by comparing the power of the sound to a reference level, which is typically the threshold of human hearing.
10-10 = 0.0000000001 or 1x10-10 in standard form.
+ (plus) - (minus) / (divide) * (multiply) ^ (power) = (equals)

The power of a sound wave directly affects its intensity and amplitude. Higher power results in greater intensity and larger amplitude of the sound wave.
The intensity physics formula used to calculate the intensity of a given phenomenon is I P/A, where I represents intensity, P represents power, and A represents the area over which the power is distributed.
