What is NIHL?

Noise Induced Hearing Loss (NIHL) results from damage to the auditory hair cells within the inner ear. These small sensory hair cells convert the sound energy into electrical signals that travel to your brain.

At birth you (and your children) have 15,000 auditory hair cells in each ear; you don’t get more and when they are gone they are gone. Exposure to large sound doses destroys your auditory hair cells and permanently damages your hearing. The biggest source of large sound doses for most of us is from the recreational use of headphones and with the exponential growth in digital media (which requires us to use headphones more often for longer) the risks of you or your children suffering from noise induced hearing loss are rapidly increasing.

Deafness Research UK research states that “1 in 3 of the population under 35 has chronic permanent hearing damage as a result of using headphones for music and gaming that is irreparable and irreversible”

NIHL harms cells beyond repair, which will result in the loss of your hearing and have a devastating impact on your everyday life.

The EU recognises NIHL as a serious issue, with scientists warning of the health risks caused from exposure to noise from personal music players.

The World Health Organisation claim that “66% of surveyed MP3 player users are listening to music louder than 85 decibels” (100 decibels is equivalent to hearing a pneumatic drill 10 feet away) and that 1.1 billion teenagers and young adults are at risk of hearing loss due to the unsafe use of personal audio devices, including smartphones.

Deafness Research UK state “58% of 16 to 30 year olds are completely unaware of any risk to their hearing from MP3 players”

Action on Hearing Loss (previously the Royal National Institute for the Deaf) say “39% of 18 to 24 year olds listen to personal music players for at least an hour a day and 42% admitted they thought they had the volume too high, with “A third of people under the age of 35 have experienced ringing in the ears, a sign of hearing damage, after listening to loud music” according to Deafness Research UK.

How LimitEar Helps

LimitEar technologies can be integrated either into the headphone or earpieces or run as a smartphone app to help prevent NIHL. Patented Hearing Dose Management® (HDM®) technology lets you to listen as loud as is safe for as long as you want.
