Long or repeated exposure to sounds at or above 85 A-weighted decibels (dBA) can cause hearing loss. Sounds at or below 70 dBA are generally considered safe.
Understanding Decibels and Hearing Loss
Sound is measured in decibels (dB). The higher the decibel level, the louder the sound. Prolonged exposure to loud noises damages the delicate hair cells in your inner ear responsible for hearing. This damage is cumulative and can lead to Noise-Induced Hearing Loss (NIHL). The louder the sound and the longer the exposure, the quicker NIHL develops.
Examples of Dangerous Noise Levels:
- 85 dBA and above: Repeated or prolonged exposure can cause hearing loss. This level is comparable to heavy traffic or a noisy restaurant.
- Common sounds above 85 dBA: Power tools, concerts, and some sporting events frequently exceed this threshold.
Protecting Your Hearing:
- Limit exposure: Reduce the time spent in noisy environments.
- Use hearing protection: Wear earplugs or earmuffs in loud environments like concerts or construction sites.
- Turn down the volume: Listen to music and other audio at a safe level. Avoid using headphones at maximum volume for extended periods.
The information provided here emphasizes that consistent exposure to sounds above 85 dBA poses a significant risk to hearing health. While occasional exposure to loud sounds may not cause immediate damage, it contributes to the cumulative effect that can lead to hearing loss over time.
