Hearing Protection March 27, 2009
Many construction trades are overexposed to noise. In time, overexposure can damage your hearing.
Hearing loss prevents you from hearing other hazards on the job. It also causes problems in your personal life.
Interferes with how you hear normal speech.
Prevents you from socializing.
Can cause high blood pressure.
Hearing loss is preventable. The best prevention is hearing protection.
Noise is any unwanted sound. There are two types – continuous noise, such as an air conditioner, and impulse noise, such as a gunshot.
Noise is measured in decibels (dB). For example, a quick-cut saw produces 115 decibels, a jackhammer 110 decibels, and a drill 100 decibels.
Noise power doubles every time noise increases 3 decibels.
Think about that. When the noise level is 80 decibels and it goes up to 83, the noise is twice as loud.
In the same way, the noise level drops 3 decibels when you double your distance away from it.
Without hearing protection, your safe working limit for an 8-hour day with no other noise exposure is 85 decibels. This is the loudness of a room full of people.
When noise cannot be reduced or controlled, wear hearing protection.
