The effects of noise
pollution depend on the susceptibility of the individual, nature of the noise,
and duration of exposure.
The impact of noise on human health can be classified into the following
categories.
1- Auditory Health Effects
2- Non-auditory Health Effects
1- Auditory Health Effects:
Noise pollution causes hearing loss:
Hearing loss results from prolonged exposure to high noise levels.
Reduced hearing sensitivity: Exposure to occupational noise can significantly
reduce hearing sensitivity.
2- Non-auditory Health Effects:
Non-auditory health effects of noise
pollution are as following:
1- Mental Health
Effects
2- Sleep Disturbances
3- Hypertension
4- Low Performance
5- Cardiovascular and Physiological Effects
1- Mental Health
Effects:
Noise in the industry can
be a direct cause of general health problems. It can create conditions of
psychological stress, which can in turn cause physiological stress reactions.
2- Sleep
Disturbances:
It has been found that
more sleeping medicines are consumed by people living in noisy areas than in
quieter areas.
3- Hypertension:
Prolonged exposure to
high-intensity industrial noise increases the risk of hypertension.
4- Low Performance:
Workers in the industry
with high noise levels show slightly lower productivity than those in
departments with lower noise exposure.
5- Cardiovascular and
Physiological Effects:
High levels of noise are associated with
a high risk of physiological changes such as hypertension, increased levels of
heartbeat rate.
Aircraft noise exposure was related to
more medical treatment for heart trouble and hypertension.
