According to Wikipedia, Earphone also known as headphones, headsets, earbuds, stereophone. The use of earphones, for almost most people, especially teenagers, are very popular for listening to music through earphones connected to the devices such as mp3 music players, iPods or other.
The presence of these earphones are very popular, in addition to generating a more dynamic sound, loud, also gives the impression of private for its users, so only users who may listen to the voice earphonelah being played from the music player.
Be careful with the habit of using earphones, the researchers from the EU's Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR), declared the use of earphones, accidentally it can lead to damage of hearing. The researchers now also believe, the increasing popularity of the music player it will only make all the worse.
The EU's Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) estimates, about 5 to 10 percent of music player users risk permanent hearing loss if they listen to music more than 1 hour a day with high volume levels at least for a period of five years. Whereas for the intensity of the resulting sound through earphones can reach 87-100 dB, and when I hear the voice on the intensity for 8 hours per day may increase the risk of hearing loss significantly.
The intensity of sound below 70 decibels (dB) - such as ringing phones, everyday conversation, the noise in the restaurant, do not pose the risk of hearing impairment (regardless of duration of hearing). Anything louder than 85 dB-like sound of the motor, workshop tools, lawn mowers, can eventually cause loss of hearing.
Before it's too late, it helps us recognize the symptoms of hearing loss caused by noise, these symptoms include:
- Ear buzzing and bordering
- Sound a little muffled
- Difficulty understanding speech, especially in a crowded so you should focus on what was said by someone
