Last week we began a two part series on noise pollution and hearing loss. The third kind of pollution problem recognized by people today is this. Persons laboring for long hours in environments that have loud and continuous noise is extremely likely to have either partial or total hearing loss. Blame it on tractors and other similar machines that run full on long hours. As soon as one is exposed to loud machines and hears constant ringing, he is bound to enter into a hearing problem.
But being exposed to loud noises for just a few minutes occasionally will not be threatening or lead to permanent hearing loss, as reported by industrial hygienists who have researched about hearing problems among those who work in factories. Make sure that all motorized equipment are kept well for this will certainly go a long way toward kicking the bark and bite out of the usual noise generated by the engine. Replacing a muffler gone bad entails that it be done with a specified type. Keeping the exhaust pipe far from the operator and make sure it frequently opens up is a must. Exhaust stacks, one that end under the top of a tractor or combine cab is generally bound to create noise even as you try to muffle it.
But based on a university research, a cab added to their test tractor increased the sound level, instead of helping. The more insulation added to a conventional tractor cab interior, the more significant a decrease the sound levels will have. A one inch fiberglass over all metal surfaces that includes the roof area is enough insulation. On the cab floor, two layers of insulation were placed, followed by the original rubber floor mat covering.
But using just any insulating material might not pull it off. Depending on the material, acoustical properties differ and there is more in some than the rest. The market abounds with so many kits of material used in sound proofing. These come in handy in the aim of improving sound levels in cabs that already exist.
It would be good to move engines, air compressors and other noise makers away from the workers by relocating those machines into a different room. But if not would not come in as practical, try rotating jobs then so that not one person will suffer from prolonged noise exposure and that these people will also be able to recuperate after being exposed in the great noise for some time.
Sound deadening material is sufficient to keep the worker well insulated from the racket. But, in most instances, it will be necessary for the worker to protect his ears from the sound around. This can be done with ear muffs, ear plugs, car stuffing.
Ear muffs can protect the best when in areas of high pitched sounds such as jet airports or large turbocharged engine sites. If fitted on correctly, such styles are highly comfortable. But to create good effects, they must fit the ear perfectly. It may come as a surprise that your ability to hear what is going around your machine is not reduced at all. By cutting out the loud noise, the quieter sounds seem to come through better.
You will be able to see the worth of ear plugs for noise control as they are hand, effective and economical, just like muffs. But in order to make sure that they are sized to be very comfy and effective, they should be fitted by a doctor or a nurse only. They would not feel natural at first but after a while you will barely think they’re in your ear. They can be purchased in different sizes that will suit different workers as they come quite economical.
Controlling sound is impossible when you use ear plugs for swimming. They would not be up to the task. If one wishes to control sound, he has to look for better options than stuffing his ears with cotton.
But then disposal ear plugs can be made from many substances available. Swedish wool is a title it is commonly known to have. If you work around noisy machines and aren’t using some type of protective equipment you are only fooling yourself. 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.
