What is the impact of personal music players, earphones and music styles on output and preferred listening levels (PLL)?
Background: In the U.S., more than 48 percent of the general public are regular users of personal music players (PMPs), and an estimated 90 percent of adolescents regularly listen to music on a PMP. For each 3 dB higher than 85 dB, the time required to reach a noise dose (leading to induced hearing loss) is halved.
