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?
At a recent rock concert, a dB meter registered 120 dB when placed 1.60 m in front of a loudspeaker on the stage. (a) What was the power output of the speaker, assuming a hemispherical radiation of the sound and neglecting absorption in the air? W (b) How far away would the intensity level be a somewhat reasonable 85 dB? m
30 seconds of exposure to 115 dB sound can damage your hearing, but a much quieter 94 dE may begin to cause damage after 1 hour of continuous exposure. Part A You are going to an outdoor concert, and you'l be standing near a speaker that emits 56 W of acoustic power as a spherical wave. What minimum distance should you be from the speaker to keep the sound intensity level below 94 dB? Express your answer to two significant...
