Prevention of noise-induced hearing loss is possible, but you must first reduce your exposure to loud noise. In other words, break your habit with loudness! Of course, this is virtually impossible for soldiers and military personnel who are bombarded with gunfire, vibrations, blasts and explosions daily. Still, you can take precautionary steps by wearing special earmuffs or ear plugs.
Also, if you are attending a concert, wear ear plugs to protect your hearing and to prevent nerve damage or destruction to the delicate tissues in the ears. If you are using power equipment, wear ear plugs. Or if you travel frequently, consider using ear plugs to lower the exposure to noise and vibrations caused by the airplane.
Most importantly, get your hearing tested annually by an otolaryngologist. This is a medical doctor who specializes in diseases of the ears, nose, throat, neck and head. A hearing test is especially important if you have had a lot of loud noise exposure or are concerned about symptoms of hearing loss.
