Side effects of noise. loss of hearing. stress. accidents. behavioural effects. negative impact on health. Noise means different things to different people (e.g. rock music and elderly parents). Noise can get in the way of sounds we would rather hear. We are exposed to noise at work, home and in traffic. If it gets loud enough it can cause problems. Hearing is one of lifes important gifts (babies crying, etc.) How it effects us depends on age, health, frequency of sound, length of exposure. (i) Continuous - music, grinders, engineers running. (ii) Impulse - pneumatic tools, punch press, gun shots - more damaging. Difference - length of time over which the sound occurs, both can create noise at damaging levels. Side effect of noise: (i) Behavioral effects - annoyance and agitation. (ii) Stress induced problems - high blood pressure and stomach ulcers. (iii) Fatigue and impaired concentration causes an increase in errors. (iv) Speech interference - poor communication and safety risks causing. accidents.
