According to a
study from the Center for Construction Research and Training, thousands
of construction workers every year experience hearing loss from noise exposure
on the worksite. The same study notes that while OSHA has
listed the official “permissible exposure limit” (PEL) for
construction noise to 90 A-weighted decibels (dBA) over a period of eight
hours, noise-induced hearing loss (NIHL) can result from extended exposure of
just 85 dBA. Here’s what you need to know about avoiding NIHL.

Know the Statistics

Even if it seems like it isn’t affecting you in the present,
NIHL will occur over time if you fail to wear hearing protection. The Centers
for Disease Control (CDC) recognizes
hearing loss as the third most common physical condition
among adults in the U.S. The CDC
reports that about 51% of all construction worker have been exposed
to hazardous noise, and 31% of noise-exposed workers report not wearing hearing
protection. Out of workers who are regularly exposed to noise, about 25% have a
material hearing impairment that impacts their day-to-day activities. About 14%
of all construction workers – not just noise-exposed workers – have hearing
difficulty, and 7% have tinnitus. By knowing these statistics, you can
understand just how pressing of an issue NIHL is for construction workers and
react accordingly.

Different Jobs Mean Different Noise
Levels

Depending on your job function, the level of noise can greatly
vary. According to EHS
Today, the loudest tasks within construction include chipping
concrete, operating bulldozers, and using a grinding wheel. The loudest tools
are a chipping gun, powder-actuated tool, and stationary power tool. If you regularly
perform one of these tasks, you are likely already prepared for protecting
yourself against noise. However, even if you work in a different trade, working
in close proximity to loud noises can still cause hearing loss. Always be
prepared and have hearing protection readily available, even if you’re not
working directly on a loud task.

Pick the Right Hearing Protection

There are many types of hearing protection options to choose
from. OSHA mandates that it is the employer’s responsibility to provide a
variety of suitable hearing protection devices for workers. There are generally
two categories to choose from: ear plugs or ear muffs. Ear plugs mold and shape
to the ear canal, so it is important that you get the correct fit. For this
reason, they come in a variety of sizes, styles, and materials, including both
plastic and foam. Ear muffs provide full protection by sealing around the ear
to protect you from hazardous noises. Electronic ear muffs are specifically
designed to simultaneously block dangerous noises and still manage important
worksite sounds, such as alarms or warning signals. Decide which fit and
material is best for you.
