7. (10 points) Given three pure tones with the following frequencies and intensity levels: 100 Hz at 60 d8, 500 Hz at 70 dB, and 1000 Hz at 80 dB. (a) Compute the total loudness in sones of these three pure tones. (b) what is the combined intensity level of the three, and (c) Find the intensity level of a single 2000-Hz pure tone which has the same loudness as all the three pure tones combined

. A sound wave at the 7 decibel level of loudness has what intensity? If the amplitude of this wave were doubled, what would be the 1oudness in decibels? Explain how you would compute the combined loudness level of two sounds which are individually at B dB and β2 dB
A 85.0-Hz sound wave is barely audible at a sound intensity level of 60.0 dB. The density of air at 20.0°C is 1.20 kg/m3. Speed of sound in air at 20.0°C is 343 m/s. What is the displacement amplitude of a 85.0-Hz sound wave?
A 72.0-Hz sound wave is barely audible at a sound intensity level of 60.0 dB. The density of air at 20.0°C is 1.20 kg/m3. Speed of sound in air at 20.0°C is 343 m/s. What is the displacement amplitude of a 72.0-Hz sound wave? Answer in nm
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;...
