Find energy absorbed by the detector

Reference no: EM13305175

A 30-dB sound wave and a 20dB sound wave simultaneously strike a sound detector with an area of 5*10-1 cm2.

1. Find the combined sound level in dB of the two sound sources (note: sound intensities are additive)

2. Find energy absorbed by the detector in 3 hours?
