You stand 30 m from a large speaker at a concert, and the intensity of the sound you hear from that speaker is 4×10−2 W/m2 . How much power is the speaker emitting? What is the intensity of the sound from the speaker at a distance of 60 m ? The pain threshold for humans is a sound intensity level of about 120dB. At what distance from this speaker would the sound be painful?
Normal conversation in an office produces a decibel rating of 50 dB. How many identical voices could you add without exceeding a sound intensity of 100 dB? ___ voices
