International Occupational Hygiene Association
We assess the risks from noise by;
Permanent hearing loss ‘Noise Induced Hearing Loss (NIHL)’
emporary hearing 'Tinnitus' (ringing in the ears)
Permanent damage caused by high ‘peak’ levels of noise
Stress, disturbed sleep patterns
Increased absenteeism and employee turnover
Lowered work performance and communication problems
Contribution to workplace injuries and accidents
Measuring daily noise exposures using dose
meters
Measuring noisy sources using a precision sound level meter
Conducting noise mapping to identify high
noise areas
Evaluating the adequacy of existing noise control measures
Control of Exposures to noise is achieved by;
Assessing the suitability of hearing protection using octave
band analysis
Providing advice on ‘Hearing Conservation Programmes’
Advising on engineering controls to
reduce noise
Providing education/training on risks from noise and ways to minimise such risks
