ACOUSTIC SAFETY
The use of headsets with mobile phones has become increasingly popular with customers, particularly those who use the MP3 feature of their phone to listen to music and with gamers. We, therefore, created this website in order to provide customers with best practices for using their headsets.

Security Implementation
/!\ WARNING: Exposure to loud noises from any source for extended periods of time may affect your hearing. The louder the volume sound level, the less time is required before your hearing could be affected.

To protect your hearing, some hearing experts suggest that you:

  • Limit the amount of time you use headsets or headphones at high volume.
  • Avoid turning up the volume to block out noisy surroundings.
  • Turn the volume down if you can't hear people speaking near you.

If you experience hearing discomfort, including the sensation of pressure or fullness in your ears, ringing in your ears, or muffled speech, you should stop listening to the device through your headset or headphones and have your hearing checked.

Information on Hearing Damage

Understanding Noise Induced Hearing Loss
Exposure to loud sounds can damage your hearing, causing hearing loss and tinnitus (ringing or buzzing in the ears). While a variety of things can lead to hearing loss, including aging and side effects of certain medications, the most common cause of non-age-related hearing damage is loud noise. Extremely loud sounds, such as gun shots or firecrackers at close range, can cause immediate hearing damage. Hearing damage can also occur over time due to repeated exposure to loud sounds such as industrial noise or loud music. With continued exposure to loud noises, ears may become accustomed to the sound level, which may result in permanent damage to hearing without any noticeable discomfort.

Temporary and permanent hearing loss
Noise induced hearing loss and tinnitus may be temporary or permanent. Ears typically recover from temporary hearing damage in a short time. However, ears may not recover completely, and some damage may be permanent. Repeated exposure to loud sound can cause more and more damage, and eventually lead to serious hearing problems. Scientists generally agree that, over time, exposure to harmful levels of noise can lead to permanent noise induced hearing loss by damaging and/or destroying the inner ear's sensory hair cells.

Loud sounds + time = hearing loss
The more time you spend exposed to loud sounds, the more likely you are to damage your hearing. All of the loud sounds that you are exposed to during a day add up - continued exposure to loud sounds can prevent your ears from recovering and also cause additional damage.

Symptoms of Hearing Loss
While not all noise induced hearing loss is noticeable, symptoms may include a sensation of pressure or fullness in your ears, ringing in your ears, or muffled speech. If you experience these symptoms or believe you may have experienced noise induced hearing loss, you should have your hearing checked by an ear doctor or audiologist.
