1 Review Constants Periodic Table 30 seconds of exposure to 115 dB sound can damage your hearing, but a much quieter 94 dB may begin to cause damage after 1 hour of continuous exposure. Part A You are going to an outdoor concert, and you'll be standing near a speaker that emits 43 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...
