Preparing for a Hearing Test: Do’s and Don’ts
Hearing loss might seem like a big challenge to tackle if you don’t know
Understanding Noise-Induced Hearing Loss and Its Prevention
The Basics of Noise-Induced Hearing Loss
Noise-induced hearing loss occurs when harmful sound levels damage the hair cells in our inner ear. These hair cells convert sound waves into signals for our brain to interpret. Once damaged, they cannot regenerate, resulting in permanent hearing loss. Both a one-time exposure to an intense sound, such as an explosion, or continuous exposure to loud noises over time can cause this damage.Recognizing Dangerous Noise Levels
Noise is measured in decibels (dB). Normal conversation level is around 60 dB, which is safe for our ears. However, regular exposure to noise levels above 85 dB can be harmful. As a reference, the sound of heavy city traffic or a lawn mower is around 85 dB, while concerts and power tools can reach 100-120 dB.Prevention Strategies
Fortunately, noise-induced hearing loss is preventable. Here are some strategies to protect your hearing:- Avoidance and Distance: The simplest strategy is to avoid loud noises when possible. If avoidance is not an option, try to maintain a safe distance from the noise source.
- Using Protective Gear: If you work in a noisy environment or enjoy loud recreational activities, consider wearing earplugs or earmuffs. These devices significantly reduce the sound intensity reaching your eardrums.
- Limit Exposure Time: The duration of exposure to loud noise also contributes to hearing loss. Limiting this time can help protect your hearing.
- Keeping the Volume Down: When listening to music or watching television, keep the volume at a comfortable level. A good rule of thumb is to set the volume at a level where you can still carry a conversation with someone next to you.
