When an object is vibrated, its motion is transmitted to the surrounding air producing waves that are detected by our ear, and it is when we perceive the sound. Noise can be defined as an annoying or simply unwanted sound. The minimum decibel (dB) level of a shot is a noise by definition.
The firing of a firearm is at least above 115 (dB) which is already considered as a very dangerous area. Consequently, any shooter who does not want to be deaf or soon must take all the possible precautions. These measures are simple if they are known. The most classical method known, which is not the advisable, are the wax and cotton stoppers.
Characteristic Magnitudes of the Sound
Sound level, expressed in Decibel (dB)
Frequency, measured in Hertz (Hz)
Exposure to high noise levels over prolonged periods leads to deafness or hearing loss.
Characteristics of Hearing Loss due to Noise
It is a deterioration at the level of the inner ear.
It is irreversible.
It affects both ears equally.
Deterioration takes place initially at the frequency of 4,000 Hz. And if proper measures are not taken, the hearing loss turn out to be wider and deeper.
Effects of Noise on Hearing
Exposure to noise produces two effects which are as follows;
It is the sudden hearing loss caused by the impact of noises such as explosions.
Permanent Hearing Loss
It is from the repeated exposure over long periods of time to high intensity noises. It is irreversible for the reason that it destroys the auditory cells of the cochlea that are auditory receptors.
Excessive noise causes incurable deafness and other discomforts such as the following;
You are supposed to take into account the following;
The noise affects your hearing in a long term process and the person does not realize it in time the deterioration suffered.
