The potential risks of occupational noise exposure can be reduced through the accurate measurement of noise. Measurement of noise level is required to be carried out by a diverse range of industries, not just those involved in heavy fabrication. Everything from the entertainment to education, services to agriculture sectors, need to regularly conduct the measurement of sound so that they reduce the risks occupational noise poses to employees.
Measurement sound
One of the most commonly used and accurate ways to carry out the measurement of sound is by using sound level meters. These hand-held instruments contain a microphone, which picks up the sound waves in a given space and takes an accurate measurement of noise levels.
As well as being used in occupational noise assessments, the efficient measurement of noise through sound meters, proves to be an effective method in noise pollution studies, as well as in environmental and aircraft noise.
Measurement noise through dosimetry
Another effective instrument used in the measurement of noise level is the sound dosimeter. These small and highly precise devices are usually necessary within a workplace setting if the levels of noise vary throughout the working day and/or if employees are mobile, for example, they drive vehicles. Another reason a noise dosimeter may be more useful than a noise level meter in the analysis and measurement of noise, is if employees work in areas that may be impractical or unsafe for a noise level meter to be used.
The measurement of noise through these highly accurate instruments, provide employers with knowledge of the intensity of noise levels being produced in their working environment on a daily basis, and the noise levels their employees are regularly exposed to.
Employers can then act accordingly. For example, if through measurement, noise levels are found to be too high and either reach or exceed the limit of noise exposure set by noise health and safety standards, employers must take the necessary measures and precautions to help safeguard the hearing of their employees.
These measures can range from educating and training people about noise exposure and the risks, to providing hearing safety equipment. For employers that rely on noisy machinery and equipment, they may be required to replace noisy machinery with quieter versions, or use dampers to help control the noise at work.
Failing to take these steps and failing to carry out regular and accurate measurements of sound, will mean an employer is at risk of being non-complaint with health and safety legislation and could potentially be putting the hearing health of their workers in jeopardy.
