Noise Consequences and Types of Noise Pollution
Noise is a type of pollution which emits distracting, irritating or damaging sounds that damage the ears. Noise pollution does not constitute physical particles but waves that interfere with the natural reverberation found in the environment. Hence, there is much debate as to what constitutes what we perceive as noise since people in general have various thresholds for it.
But in its narrow sense, noise becomes a disturbance when it already starts to adversely affect wildlife and human activity, which means physical and psychological distress on repetitive intervals. In its broadest sense, noise can be considered as disruptive when it starts to intervene with the natural sounds in any surrounding and causes harm even when it does not occur repetitively. Decibel is the logarithmic unit used to measure the intensity of sounds. It is usually the measurement used to identify the parameters of acceptable and excessive sound levels.
Meanwhile, noise can come from sources that don’t deliberately produce noise. For instance, traffic jams can be called as a form of physical noise. There are also other types of noises. One is psychological noise which is the mental interference that impedes a person from listening or communicating. An example of this is when a person’s mind wanders while another person is talking or when one's attention is distracted.
Another is physiological noise that pertains to physical problems that may impede people from hearing properly. For instance, having a headache or ringing sound inside your head can cause hearing problems. Fortunately, there are hearing aid shops that provide hearing aid brands appropriate for any hearing needs.
Pollution pertaining to physical noise is fast rising due to the increasing utilization of heavy machines and other equipment. Moreover, the continuing construction of urban areas and seaports and airports add to this disturbance. It is said that the acceptable level of sound is around 80 decibels and cannot go beyond that because it causes temporary or permanent deafness. If you think you have experienced ringing sounds and find it hard to communicate, you should consult a doctor who can prescribe hearing aid devices appropriate for you.
Sound intensity of 100 up to 160 decibels commonly found in aircraft engines can cause eardrum rupture and permanent damage when exposed even only for a couple of hours. Permanent hearing damage may mean that people would need the support of hearing devices. Thus prevention is still the best cure when it comes to this problem. Conversely, even for those who cannot hear in normal decibel levels can avail hearing aid devices to amplify their hearing.
