When the fire truck is at rest

Reference no: EM13317367

A fire truck siren produces a steady single tone of frequency 500 Hz when at rest. When the truck is at rest, the siren produces a sound level of 96 dB at a distance of 2.0 m away. Assume the siren radiates spherical sound waves.

When the fire truck is at rest, what is the sound level at a distance 10 m away from the siren (dB)?
