An opera singer produces a decibel level of 108 dB at a distance of 0.700 m. The area of a typical eardrum is about 5.00 x 105 m. Assume the sound propagates as a spherical wave. Determine the sound intensity I and power P incider on a typical eardrum at distances of 7.00 m and 22.0 m from the singer. (a) 7.00 m from the singer P= 38.9 W/m (b) 22.0 m from the singer W/m An opera singer produces a decibel level of 108 dB at a distance of 0.700 m. The area of a typical eardrum is about 5.00 x 105 m.
