A typical eardrum is 9 mm in diameter. You have a speaker which can produce 230 W of sound energy. The speaker radiates sound in all directions. How much sound energy is incident on the eardrum in 1s. a) at the threshold of hearing (0 dB)? o) at the threshold of pain (120 dB)? c) How far away from the speaker is your eardrum if you experience pain from the sound (this is the distance from the speaker and your eardrum, NOT the radius)?
