We fostered a two part talk on noise troubles and hearing loss just in the last week. The third kind of pollution problem recognized by people today is this. Anyone who works for long periods of time in conditions of loud and continuous noise is in danger of losing part or nearly all of his hearing. Put the blame on machines that need to be in operation for long hours like tractors and other machines. The kinds of machines that make noise loud enough to make the ears feel a ringing sensation can do harm.

But based on the study conducted by industrial hygienists, permanent hearing damage is not likely among those who only get minimal exposure to loud situations such as factory workers. When you keep motorized equipment in mint condition, you take the first step in eradicating the bark and bite in engine noise. The muffler that goes wrong must be replaced with a type that has been specified. Most importantly, keep the exhaust pipe opening and make sure that it is never near the operator. If an exhaust stack in a tractor or combine cab ends below its top, this is greatly bound to create noise trouble.

But then by adding a cab to the test tractor, the sound grew and did not minimize as what was intended, and this is based on a University research. The interior of a conventional tractor will reduce the sound level significantly once insulation is added. An inch of fiberglass covering upon all metal surfaces even the roof area is good enough insulation. Upon the cab floor, two layers of insulation were set while the original rubber floor mat covering followed after.

But just using anything for insulation might not suffice at all. Materials have more acoustical properties than others. Kits of material for sound proofing are now coming on the market. These come in handy in the aim of improving sound levels in cabs that already exist.

Relocating noisy machines like air compressors into areas that are not worked at by employees should be considered. But then try rotating jobs so that not one person is immersed for more than the minimum time without a chance to recuperate from the extremely loud noise, if the relocation of equipment is not practical.

Insulating the workers from the din can be achieved with the use of sound deadening things. But at times, it is crucial for the worker to protect himself from the surrounding sounds. Ear muffs, ear plugs and car stuffing should be able to carry this out.

Ear muffs can protect the best when in areas of high pitched sounds such as jet airports or large turbocharged engine sites. Once they are properly fitted in, you will find that there is much comfort in wearing these styles. But to create good effects, they must fit the ear perfectly. Surprisingly, they do not reduce your ability to hear what is going on around your machine. By shutting out loud noise, quieter sounds can flow in better.

Noise control ear plugs, like ear muffs, are very economical, effective and handy. But put your trust only on either a nurse or doctor who possess the ability to shape them to be effective and comfortable at all times. You might feel them being foreign objects in the ear but after a few minutes, you will barely feel them there. Being inexpensive, you may afford to buy several sizes which different workers can use.

Ear plugs created only for swimming are not effective sound controllers. They will reject such a task. It is unwise to stuff the ears with cotton if you wish to control noise.

There is a plethora of substances that can create disposable ear plugs. Generally, this is referred to as Swedish wool. Working in an area with noise making equipment without any hearing protection is very foolish. Eventually, as you spend so much on medical treatment and hearing aids, you will wish that back then you already invested in ear protection equipment.
