If you work somewhere like a construction site, your employer should provide hearing protection for you. If you work in a noisy environment or enjoy hobbies that involve noise exposure, it’s important to invest in hearing protection… and then actually wear it. Hearing loss caused by noise exposure, also called noise-induced hearing loss, is preventable in most cases. Here are some everyday sounds and their decibel outputs for reference: City traffic at 85 dB can damage your hearing after eight hours or more of exposure, while a 100-dB sound like a motorcycle engine can cause damage in just 15 minutes. The louder a sound is, the more quickly it can damage your hearing. What Level of Sounds Are Safe?Īny sound louder than 85 dB can cause hearing damage over time. Therefore, an 80-dB sound is 10 times louder than a 70-dB sound. This means that for every 10 dB increase on the decibel scale, there is a 10-fold increase in volume. The decibel scale is logarithmic rather than linear. The more amplitude a sound has, the louder it is and the higher the decibel rating. Another way to say this is they measure the amplitude of soundwaves. What Is a Decibel?ĭecibels measure the loudness of sounds. This information includes what the quietest sound that you can still hear is, which is measured in decibels. When you get a hearing test, your audiologist will show you your results on an audiogram, which is a chart that shows the exact specifications of your hearing loss.
