Not only can noise distract, disturb and interfere with communication and sleep, it can affect your performance, behavior and hearing.
In many cases, hearing loss can be prevented by recognizing sources of damaging noise levels and using appropriate protective equipment. However, excessive noise exposure can cause permanent hearing loss that cannot be treated with medication, or result in constant ringing in your ears called tinnitus. Impaired hearing can reduce your ability to recognize your surroundings and listen for cues of potential danger.
Learn how to protect yourself from future hearing damage with this advice from Guard Your Health, a health education campaign by the Army National Guard:
- Know the safe volume limit to protect yourself from future hearing damage. Noise that is 0 to 80 decibels is generally safe, while noise that is 140 to 200 decibels can be dangerous.
- Noise that exceeds safe parameters, even if it's under 140 decibels, can still cause damage to your hearing over time. A general rule of thumb is the "three feet rule." If you have to shout to someone who is three feet away (about an arm's length), the noise level in that location could be damaging.
- Be aware that a single exposure to a very loud sound (such as weapon fire) can cause permanent hearing loss.
- Using proper hearing protection for the environment can help prevent damage to your eardrum and hearing. There are several types of hearing protection devices available including foam earplugs, silicone earplugs and earmuffs. For example, when shooting at the gun range, noise-activated earplugs can help you avoid sudden eardrum rupture.
- Foam earplugs should be pinched when inserted, allowing the foam to expand in your ear until you achieve a tight, non-painful seal. Silicone earplugs should be inserted only until you feel a slight resistance to avoid damaging your inner ear. To wear ear plugs properly, straighten your ear by gripping the cartilage and stretching it away from your body. Insert the earplug then release your ear. Do a few jumping jacks to test the security of the earplugs; if they fall out, try again or get a smaller size.
- Earmuffs should rest about two finger widths from your jawbone and completely cover your ears for a tight seal on the side of your face.
If you notice signs of hearing problems, ask your doctor to test your hearing. Common symptoms include a muffled sound in your ears after leaving a noisy area or event such as a car race, concert, wood working or hunting; prolonged ringing or buzzing in your ears after exposure to noise; and difficulty understanding what people are saying although you can hear them talking.
