Noise Pollution Effects
A noise may consist of different type of sound with varying levels of pressure operating for different time intervals. So, let us look at how noise pollution effects in our life.
Do you think how much you produce the noise per day and what are noise pollution effects?
- Loss of hearing
- Health effects
- Interference with communication
- Working efficiency
Loss of Hearing Causes by Noise Pollution
Loss of hearing occurs due to exposure to noise, which termed as the artificial hearing loss.
This loss divided into two types:
Noise-Induced Temporary Threshold Shifts (NITTS)
The NITTS caused due to exposure to loud noise like bursting of crackers. So, this process can recover in a short period.
Noise-Induced Permanent Threshold Shifts (NIPTS)
The NIPTS occurs because of exposure to loud noise for an extended period.
Annoyance in Noise Pollution Effects
There is a subjective matter for a noise. Someone may like classical music; it may annoy other.
General annoyance felt at about 75 to 85 db. Blood vessels get constricted, the breathing rate is affected, and musical tension changes.
Effects on Physical Health
Auditory effects and Non-auditory impact.
They grouped into the short time and long-time effects. Thus, the acoustic trauma caused by a very high-intensity impulsive noise of about 150 db or more from an explosion.
Exposure to loud noise may increase the pulse rate and blood pressure changes.
Body experiences fear reactions and Disturbed brain waves lead to the interference in vision.
Effects on Mental Health
Impact on mental health is less.
Lack of concentration at high noise level and mental disorientation are some of the effects on mental health.
Interference with communication
A person may face the problem of trying to understand another person talking to him/her in an environment with a high background noise level.
Background noise level can thus affect the efficiency of offices, school and other places where communication is of vital importance.
Furthermore, external sounds can also interfere with conversation and use of the telephone.
The working efficiency found to decrease drastically whenever a person works in the noisy environment.
Thus, Experiments indicate that intermittent bursts of noise are more disruptive than steady noises.
Other Noise Pollution Effects
- Sleep interference
- Increased industrial accidents
- Personal comfort interference
- Property value degradation
- Effects on wildlife
Control of Noise Pollution
- Proper maintenance and lubrication of machine can reduce noise.
- Sources of noise pollution like heavy vehicles, airports, noise-producing industries etc. should be located away from populated areas.
- Silence zones should be created around residential areas, educational institutions, and Noisy machines should be installed in the soundproof chamber.
- Planting more trees having broad leaves which can absorb sound.
- And, the use of loud-speakers and amplifiers should restrict to a fixed intensity and fixed hours of the day.
- Occupational exposure to noise can reduce by using protective devices such as the ear.
- Restricting the unnecessary horn blowing bylaws.
