Noise-Induced Hearing Loss: Causes, Symptoms, and Prevention
Hearing is one of our most precious senses, allowing us to connect with the world around us. However, repeated exposure to damaging noise or even one sudden, loud noise can lead to noise-induced hearing loss. According to the CDC, 17% of adults between the age of 20-69 years have permanent damage to their hearing due to noise. Noise-induced hearing loss, as the name suggests, is a type of hearing impairment caused by exposure to loud noises. It is the second most common cause of hearing loss, after age-related hearing loss (presbycusis).
What is Noise-Induced Hearing Loss?
Noise-induced hearing loss occurs when the delicate hair cells in the inner ear, responsible for transmitting sound signals to the brain, become damaged or die due to excessive noise exposure. This condition is caused by repeated exposure to damaging noise or even one sudden, loud noise-it is also preventable.
Causes of Noise-Induced Hearing Loss
Noise-induced hearing loss is caused by either recreational or occupational noise:
- Recreational Noise: Loud music, concerts, headphone use, etc.
- Occupational Noise: Many jobs involve exposure to high noise levels, including construction workers, factory employees, and musicians working in a factory, industrial sound, working on a construction site without hearing protection.
Symptoms of Noise-Induced Hearing Loss
Noise-induced hearing loss typically develops gradually, making it easy to overlook in its early stages. Typically, noise-induced hearing loss occurs in both ears and is characterized by not being able to hear noises between 3,000 and 6,000 Hertz (hz). The main symptoms of noise-induced hearing loss often go away after the exposure to the noise ends. If the noise exposure is repeated and more cells are destroyed, then you can develop lasting hearing loss.
Prevention of Noise-Induced Hearing Loss
The good news is that noise-induced hearing loss is largely preventable. Noise-induced hearing loss can be prevented by using hearing protection. Hearing protection is widely available online and in stores and comes in many varieties. The cost of the protective gear largely determines the level of protection it provides.
Types of Hearing Protection
- Banded ear muffs - This form of hearing protection is made up of ear muffs connected by a headband.
Additional Preventive Measures
- Lower the Volume: When using personal music players or watching TV, keep the volume at a reasonable level.
- Take Breaks: Give your ears a break from noise.
The Importance of Early Intervention
Early intervention can help catch potential issues before they become significant problems, ensuring that you can continue to enjoy the sounds that matter most to you. Regular hearing check-ups, avoiding exposure to loud noises, and using ear protection when necessary can go a long way in maintaining your hearing health.
Remember, your hearing is invaluable, so take the necessary precautions to preserve it for years to come. Schedule a complimentary hearing assessment to find out if you have noise-induced or any other type of hearing loss.
