What is the decibel level of a dog barking with intensity 10−5 watts per square inch? Use a logarithmic model to solve.
1 answer:
Answer:
The sound intensity is about 101.9 dB
Step-by-step explanation:
Sound intensity is the amount of sound energy per unit area.
The intensity of the dog bark is 10⁻⁵ W/in². The intensity of sound in decibels is given by:

I = 10⁻⁵ W/in² = 0.0155 W/m²
Therefore:

The sound intensity is about 101.9 dB
