2) A referee whistle has a sound intensity level of 71.45 dB. Find the sound intensity in watts per square meter for the whistle. Compare this to a sound intensity level of 126.0 dB for a loud stadium. Would you be able to hear the whistle in the stadium?
What intensity I1 corresponds to 20.0 dB ? Express your answer in watts per square meter. You are trying to overhear a most interesting conversation, but from your distance of 10.0 m , it sounds like only an average whisper of 20.0 dB . So you decide to move closer to give the conversation a sound level of 60.0 dB instead. How close should you come? View Available Hint(s) IVALO ? 11 = 9.9 W/m² Submit Previous Answers X Incorrect;...
5) An ultrasound wave with an intensity of 46,500 watts per square meter and a frequency of 55.0 kHz is used to shatter a kidney stone. Find the sound intensity level and the wavelength for this ultrasound wave if the wave is traveling in air at room temperature (speed of sound is 343 m/s).

9. Sound levels are measured by the logarithmic decibel scale, named after Alexander Graham Bell. The sound level, L, corresponding to an intensity of I, in watts per square metre, is し= 10 log-, where lo is the minimum intensity audible to the human ear. If amplified rock music has a loudness of 120 dB and ordinary conversation has a loudness of 50 dB, how many times louder than ordinary conversation is amplified rock music?
