The Health Effects of Noise and Best Hearing Protection Devices for it.

Health Effects of Noise

Exposure to noise acts as a stressor, activating physiological factors that, over time, can produce a range of adverse health effects.

Although all of the effects and mechanisms are not yet clearly understood, it has been demonstrated that noise can produce both acute and chronic health effects such as:

  1.  Headache
  2.  Elevated Blood Pressure
  3.  Fatigue
  4.  Irritability
  5.  Digestive Disorders
  6.  Increased Susceptibility to Colds and other Minor Infections

One of the main problems is that noise can be an insidious cause of harm. Excessive noise levels over a long period of time will damage hearing so gradually and painlessly that a person may not notice the minor deterioration from one day to the next.

The degree of loss depends on the loudness of the noise and the level of exposure. Some people exposed to excessive noise develop tinnitus, which is described as a constant ringing sound. For most cases of noise‐induced hearing loss, there is no cure. Hearing aids only amplify sounds, and can’t replace normal hearing capability.

Sound pressure is measured in decibels (dB). Like a temperature scale, the decibel scale goes below zero. The average person can hear sounds down to about 0 dB, the level of rustling leaves. Some people with very good hearing can hear sounds down to -15 dB. If a sound reaches 85 dB or stronger, it can cause permanent damage to your hearing.

The amount of time you listen to a sound affects how much damage it will cause. The quieter the sound, the longer you can listen to it safely. If the sound is very quiet, it will not cause damage even if you listen to it for a very long time; however, exposure to some common sounds can cause permanent damage.

With extended exposure, noises that reach a decibel level of 85 can cause permanent damage to the hair cells in the inner ear, leading to hearing loss. Many common sounds may be louder than you think…

Recognize the health effects of noise problem may exist, evaluate the extent of the potential problem, and control it with the following methods.

5 Best Commonly Hearing Protection Devices Used.

 Hearing protection devices provide you with the best line of defense when you cannot be able to eliminate or reduce your overall exposure to extremely loud noise sources. The best method on how to achieve hearing protection is by having  devices that is able to greatly reduce the total decibel level reaching your ear when working in a noisy environment.

Earmuffs: comprise of soft ear cushions and sound attenuating material that has been designed around your hard outer caps and the ear. These are often held together by a headband.

Semi insert ear plugs: they comprise of two ear plugs that are then held over your ear canal by a very rigid headband so as to make sure that they will not fall off.

The hearing protection devices will reduce the total amount of noise that you will be exposed to. In a work situation where hearing protection is necessary, then it will be important that a hearing conservation program be implemented.

Hearing protection devices efficiency will be greatly reduced if your hearing protector does not correctly fit your ears. Additionally, wearing them periodically will also eliminate their efficiency.

You should not modify the hearing protection device in any way if you want them to remain effective.

 Hearing Protection Comparison

 Earplugs are easy to carry around, and can easily be used with other personal protective gear. You can also use the plugs together with your muffs. Many workers consider the plugs to be the most comfortable for use when working long shifts, or when the environment at work is very humid. They are also convenient for use in spaces that are confined. Their downside is that they require a lot of time for them to be properly fitted. They are also very easy to misplace if one is not careful.

The best hearing protection earmuffs are designed in such a way that a single size can fit all types of heads. Compared to the earplugs, this is not easy to misplace, and they can be worn without exposing one to the risk of numerous ear infections. Additionally, earmuffs can be seen from a distance, enabling supervisors to determine who is, and who is not making correct use of their ear muffs. Their downside is that they tend to be heavier, and therefore less portable. Earmuffs are also very uncomfortable for use in environments that are humid, or very hot.
