Hearing loss exists when there is diminished sensitivity to the sounds normally heard. The term hearing impairment is usually reserved for people who have relative insensitivity to sound in the speech frequencies. The severity of a hearing loss is categorized according to the increase in volume above the usual level necessary before the listener can detect it.

7. Modern World Problem; Recreational Deafness4
The modern world seems bent on destroying our beautifully designed hearing system. “Recreational deafness’’ is a term solidly embedded in today’s scientific terminology.

8. Modern World Problem; Recreational Deafness4
Professional sound mixers working at 110dB levels are flirting with damaged. Some motorcycles and other off- road vehicles can generate hazardous noise levels. The very popular portable music players used with earphones can damage to our ears.

11. Noise-Induced Hearing Loss – Completely Preventable6
A major cause of hearing loss in our society is noise exposure. Tiny hair cells in the ear are damaged when assaulted by loud noise. Once those hair cells are destroyed they cannot be replaced.
Repeated and lengthy exposure to loud sound – whether is it music or a jackhammer - will eventually produce a sensor neural hearing loss.

13. Who is Under the Risk Musicians
Musicians are particularly at risk. It is their job to listen to the sounds that they and their group are producing, and these may be as high as 135 dB. They have no choice to do this as often as daily; this is their career and their lifestyle.
Musicians earplugs are available that can help. The newest and best version reduce the sound equally all across the spectrum, from low to high frequencies. Everything sounds just as good as it did before, only softer.

14. Who is Under the Risk
“If you’re listening to music at 85dB, your hearing is safe for eight hours. Then when it goes up by 3 dB, it cuts the safety time down by half.” So if you consider that the average nightclub soundsystem is around 106 dB, the maths tells you that your ears are safe in such an environment for around 4 minutes. And while hearing protection doesn’t make you immune to the perils loud sound systems, it increases this recommended safety time to 2 hours - a vast improvement...

15. Who is Under the Risk
“People think that tinnitus will never happen to them or that it is just experienced for a short while when they have come out from a club” Monika continues, “and because it goes away after a few hours, they believe it will never get to the point where it may well end up with the condition forever. If they do have it constantly but just in a mild way, they believe that it will not ever get any worse, it can and does unfortunately.7
