Did You Know?
Repeated exposure to loud noise over the years can damage your hearing—long after exposure has stopped.
This is just one of the many informative facts available on CDC’s National Center for Environmental Health’s new hearing loss website.
Think you are aware of how to protect yourself? When it comes to hearing loss, we can all think of the usual suspects: attending sporting events, entertainment venues, and loud concerts. Volume isn’t the only factor to consider. Noise exposure is cumulative. Practice safe listening at home, school, and while commuting by reducing the duration of headphone use.
Everyday activities such as using power tools, mowing the lawn, or attending a fitness or gym class with loud music can damage hearing.
Peruse CDC’s website on noise-induced hearing loss to learn more detailed information on the following topics: “What Noises Cause Hearing Loss?” “How Does Loud Noise Cause Hearing Loss?” “How Do I Know if I Have Hearing Loss Caused by Loud Noise?” “How Do I Prevent Hearing Loss from Loud Noise?” and “What If I Already Have Hearing Loss?”

Is the noise too loud? If you need to shout to make yourself heard, yes.
- Ways to protect your hearing include turning the volume down, taking periodic breaks from the noise, and using hearing protection, such as earplugs and hearing protection earmuffs.
- Signs that you may have hearing loss include difficulty hearing high-pitched sounds (e.g., doorbell, telephone, alarm clock) and difficulty understanding conversations in a noisy place.
By the Numbers
Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine is about 95 dB. Noise above 70 dB over a prolonged period may start to damage your hearing. Loud noise above 120 dB can cause immediate harm.
Hearing loss is the third most common chronic health condition in the United States. Almost twice as many people report hearing loss as report diabetes or cancer. In the United States, about 40 million adults aged 20–69 years have noise-induced hearing loss, and about 1 in 4 adults who report “excellent to good” hearing already have hearing damage.
Think that hearing damage is usually workplace-related? Activities away from work can damage hearing just as much as a noisy job. Over half of all adults with hearing damage do not have noisy jobs.
The average person is born with about 16,000 hair cells within their inner ear. These cells allow your brain to detect sounds. Damaged inner ear cells do not grow back. So, protect your hearing, and if you already have hearing loss, or are experiencing pain, discomfort, or ringing in the ears, take steps to keep it from getting worse.
