Summary Statement: Handout for Bricklayers on sources of noise, effects of noise on hearing, and how to protect yourself from noise, including selection of hearing protection. Like many construction workers, you may not hear as well as you once did, and that may worry you.
Noise exposures that are loud enough and last long enough can damage nerves in your inner ear. The legal limit for construction workers in Washington is an 8-hour (full-shift) average noise exposure of 85 decibels. If you must raise your voice to talk to someone an arm’s length away, the noise level is probably over 85 decibels.
University of Washington researchers have been measuring the noise exposures of construction workers.
We looked at whether bricklayers used hearing protectors when their noise levels were above the limit of 85 decibels. Our research shows bricklayers are often exposed to too much noise, and need to be in a hearing loss prevention program. Based on our measurements, most brick-layers will get enough protection if they wear a hearing protector with an NRR of 22 decibels. Hearing protectors are like shoes: one style will not work for all workers and all exposure levels .
Your employer may be able to reduce your exposure by using quieter equipment, blocking noise with shields, or moving noisy equipment away from you. Summary Statement: Handout for Ironworkers on sources of noise, effects of noise on hearing, and how to protect yourself from noise, including selection of hearing protection.
We looked at whether ironworkers used hearing protectors when their noise levels were above the limit of 85 decibels.


Our research shows ironworkers are often exposed to too much noise, and need to be in a hearing loss prevention program. Hearing protectors are like shoes: one style will not work for all workers and all exposure levels.
Summary Statement: Handout for laborers on sources of noise, effects of noise on hearing, and how to protect yourself from noise, including selection of hearing protection. Our research shows laborers are often exposed to too much noise, and need to be in a hearing loss prevention program.
Based on our measurements, most laborers will get enough protection if they wear a hearing protector with an NRR of 24 decibels. Noise-induced hearing loss most often results in permanent damage which cannot be treated medically. Wear hearing protection (foam or silicone plugs or muffs) when around loud equipment such as a lawn mower, power saw or leaf blower. Check with your employer regarding federal noise regulations if you are exposed to loud noise at work. Avoid medications that can be dangerous to your hearing a€“ ask a physician about possible ototoxic effects. Your concerns are real—by retirement, many construction workers have a noticeable hearing loss.
Workers with an average noise exposure above 85 decibels need to wear hearing protectors—either earplugs or earmuffs—and be in a hearing loss prevention program. This program should include noise monitoring, training, efforts to reduce noise, and use of hearing protectors.
For most activities, an NRR higher than 22 decibels will block too much sound and may interfere with communication, including warning signals.


You may have to try several styles before you find one that is comfortable and works for you.
Workers with an average noise exposure above 85 decibels need to wear hearing protectors—either earplugs or earmuffs— and be in a hearing loss prevention program.
All ironworkers should be enrolled in a hearing loss prevention program—find out if your employer has one.
For most activities, an NRR higher than 24 decibels will block too much sound and may interfere with communi-cation, including warning signals. All laborers should be enrolled in a hearing loss prevention program—find out if your employer has one. Prevention tips as well as a chart outlining decibel levels of everyday sounds are included. You and your employer need to take steps to protect your hearing, and this pamphlet will help you do so.
Construction workers in most other states have an 8-hour limit of 90 decibels enforced by OSHA.
Continued excessive exposure often results in decreased sensitivity to other types of sound, eventually impacting speech understanding.
