Precautions while using Earphones
Risk from excessive sound level
People who have to listen in a noisy environment, whether they are factory workers, sports commentators having to hear above the noise of a crowd, musicians trying to hear a backing track against the sound of a rock band, or camera operators trying to hear talkback at a live music event.
DJs and other performers. They may feel they need to hear music loudly because it gives them the buzz that helps them to do their job, or maybe they just like it loud. Maybe, even, they already have some noise induced hearing loss but unfortunately this doesnt protect against further damage.
People who have to listen on earphones for most or all of every working day, such as people working in call centres, or those working in the media who need to select or review material for programmes.
