Effects of noise pollution
Human health: Noise pollution disturbs our health and behavior in a number of ways including deafness causing lack of sleep, irritability, indigestion, heartburn, high blood pressure, ulcers, and heart disease. Just one noise explosion from a passing truck drastically alters our endocrinal, neurological, and cardiovascular functions in many individuals. If this is prolonged or frequent, the physiological disturbances become chronic and contribute to mental illness. Annoyance: Sometimes, even low levels of noise are irritating and can be frustrating, and high volumes can be annoying. Natural sounds are less irritating than those we find uncontrollable but intermittent sounds such as a tap dripping water can be more irritating than the sound of falling rain. Speech interference: Noise more than 50dB can be very difficult to hear and interpret and cause problems such as partial deafness. Sleep interference: Very high levels of noise can wake people from their sleep with a jerk and keep them awake or disturb their sleep pattern. This could make them irritable and tired the next day. Decreased work performance: Increased noise levels gives rise to a lack of concentration and accuracy at work, and reduce one�s productivity and performance. Difficult tasks can be impaired, and instructions or warnings difficult to be heard and interpreted, causing accidents. Protect Your Hearing
To avoid noise-induced hearing loss, pay attention to the noises around you and turn down the volume whenever possible. Avoid or limit time spent in noisy sports events, rock concerts and night clubs. Wear adequate hearing protection, such as foam ear plugs or ear muffs, when you must be in a noisy environment or when using loud equipment.
