We use
headphones all the time – to listen to MP3s and DVD’s, play musical
instruments, and more. But how exactly do they work?
Essentially,
headphones are a pair of transducers that receive electrical signals from some
sort of media player or receiver. The headphone’s speakers convert these
signals to sound waves that your ears can then hear. Based on this description,
you may immediately think of how telephones and radios function. And indeed,
headphones preceded both of these inventions.
There are
four basic types of headphones: circumpolar, supra-aural, ear-buds
earphones,
and canal phones. The differences between them are mostly visible – they vary in
size and style. A lot of people these days are concerned only on the looks and
style of the headphone...I feel that's a bad thing. You should be more concerned
about the quality and durability of the headphones you are purchasing, rather
than worry how you are going to look with them on your head. Would you rather
have a great listening experience that will last a long time, or would you
rather look better and have a bad listening experience?
However,
studies have shown that using headphones at a high volume level can lead to temporary
or permanent hearing damage. Companies have responded to this danger, promoting
safer products. Some people believe closed-air headphones, which are sealed,
are actually better for hearing than open-air headphones, which allow outside
interference. This is because people are then less tempted to turn up the
volume because the sound quality is so good already.
When
looking for a new set of headphones, you can visit your local retailer or shop
online. Wireless headphones are a popular trend and they allow users to roam
about while listening to music or other audio, rather than having to sit
stationary next to their MP3 player or computer. Whatever your needs or budget,
you’re sure to find the right headphones for you.
