Question

Answer 1

Answer:

Sound intensity can be found from the following equation:

I

=

Δ

p

2

2

ρ

v

w

Δ p – change in pressure, or amplitude ρ – density of the material the sound is traveling through vw – speed of observed sound.

The larger your sound wave oscillation, the more intense your sound will be.

Although the units for sound intensity are technically watts per meter squared, it is much more common for it to be referred to as decibels, dB.
