We are exposed to sound on a daily basis. Volume levels vary considerably, and as a general rule, the louder the noise, the quicker it can potentially harm our hearing. Prolonged exposure to even moderately loud noises can be harmful and can cause permanent, irreversible hearing loss. 85 decibels (dB) of sound pressure level is the maximal level that the Occupational Safety and Health Administration (OSHA) deems permissible for an 8 hour workday.
Excess noise exposure isn’t the only cause of hearing damage. Diseases, drugs and injury may all contribute to hearing loss. Fortunately, there are steps you can take to protect your hearing and help prevent hearing impairment.
Protecting Your Hearing from Loud Noise
Noise-induced hearing loss is the most common cause of hearing loss in the U.S. The good news? It is easily preventable. Follow these tips to protect your hearing:
- Wear hearing protection when exposed to loud noise. Earplugs should always be worn in noisy environments such as rock concerts and sporting events. They should also be worn when riding a motorcycle or snowmobile, mowing the lawn, using power tools, etc. If your job exposes you to loud noise, your employer is required by OSHA to supply hearing protection.
- Earplugs must be fully inserted into the ear canal to work to achieve the noise reduction rating marked on the packaging.
- Turn down the volume on amplified sounds. When listening to music or watching television, keep the volume low.
- Limit the number of noisy appliances running at the same time.
- Buy quieter products. Many appliances list dB ratings in their specifications.
Dealing with Sudden Hearing Loss
If you experience a sudden drop in your hearing, you have a much better chance of recovering some or all of that hearing if you seek immediate medical attention. A doctor can prescribe a corticosteroid such as prednisone which can help the ear recover from a sudden hearing loss. Our office prioritizes sudden hearing loss because treatment is time-sensitive, and we will make every effort to see you as soon as possible for diagnosis and treatment. Typically you will see the audiologist first for a hearing test, and then see the ENT doctor who may prescribe medication for you depending on the severity of the loss.
Preventing Hearing Loss from Diseases
Some diseases can cause hearing loss. Viruses that might damage hearing include measles, mumps, whooping cough and rubella. Bacterial diseases such as meningitis and syphilis can also lead to hearing damage. Acoustic neuroma – tumors on the hearing nerve (usually benign) – may contribute to hearing loss. Tips for preventing hearing loss from disease include:
- Make sure your child is vaccinated. Immunizations offer protection from many childhood infections that can cause hearing damage.
- If you are sexually active, use protection to prevent the spread of sexually transmitted diseases, some of which can cause hearing loss.
- Don’t delay seeking medical attention should you fall ill.
Protection from Ototoxic Drugs
Some drugs cause damage to the sensory cells responsible for hearing. These include certain antibiotics, chemotherapy drugs, salicylate pain relievers (e.g., aspirin), quinine (for treating malaria) and diuretics. In order to reduce your odds of hearing loss when taking medications, follow these tips:
- Take medications only as directed.
- If you experience symptoms of hearing loss such as tinnitus while taking new drugs, see your doctor immediately.
Preventing Ear Injuries
Head trauma can damage the temporal bones in the lower lateral walls of the skull, leading to hearing loss. To help prevent this type of injury, take the following precautions:
- Wear a seat belt at all times when in a car.
- Wear a helmet when riding a bike or motorcycle, and participating in contact sports.
- Don’t take unnecessary risks, such as standing on the top rung of a ladder.
There are other general steps you can take to protect your hearing. Refrain from inserting foreign objects in the ears; these can lead to impacted earwax, a perforated eardrum or damage to the skin. Cotton swabs and safety pins are notorious offenders. Use swim plugs when engaging in water activities and be sure to dry your ears thoroughly after swimming or bathing. Seek prompt medical attention if you are suffering from an ear infection.
