Finding The Right Hearing Protection

Finding the Right Hearing Protection

Honeywell, a leader in workplace hearing protection, has some excellent advice on selecting the proper hearing protection product to match the tasks your workers are performing.

Depending on your industry, you may have to contend with noise from a variety of  sources - pumps, motors, generators, assembly line equipment, production equipment, welding machines, catalysts and processing units, heavy earth moving equipment, tools and transportation noise.

Work sites often have many things happening at the same time. First, people and equipment are moving about making situational awareness critical for safety. Workers must guard against "over-protection" where the hearing protection is blocking not only hazardous noise, but prevents the user from hearing critical sounds such as communication and warning signals.

Another problem with over-protection actually leads to under-protection. When workers cannot hear their co-workers or the equipment they must monitor, they remove their hearing protection and increase the risks of noise-induced hearing loss. Earplug fit-testing can help workers select the right level of hearing protection for their environment.

Research has shown exposure to certain chemicals such as benzene, toluene and xylenes can cause damage to hearing. No matter the route of transmission, they damage the cells in the ear much like noise does. Combined exposures to both noise and "ototoxic" (ear poison) chemicals are synergistic " far worse than would be expected by noise alone or ototoxins alone.

When noise levels are extreme, the highest amount of protection can be achieved with a well-fit foam earplug, which comes in many shapes and sizes. When noise levels are just loud enough to require raising your voice to talk over, or are intermittent, multiple-use earplugs are a good choice. They can be removed and reinserted as hazardous levels of noise come and go.

If communication is vital, there are better options than removal of the hearing protector. The simplest solution is a "uniform attenuation" hearing protector. Attenuation refers to the amount of noise being blocked by the hearing protector. For most hearing protectors, high frequency sounds are more easily blocked than low frequency sounds.

Uniform attenuation hearing protection either hasfilters or electronics that allow some of the sound through to make speech understanding clearer, while restricting the hazardous noise. If communication errors can result in injuries or fatalities, but a communication system that incorporates hearing protection, active noise reduction and amplification of the communication signal can help workers communicate in dangerous and changing environments.

Finding the right hearing protection for your employees is not only required by regulation but it is the right way for workers to remain safe and sound.
