Sound measurement technology entails more than just decibel measurement. Equipment is available to monitor sound levels over a prolonged period of time, so that an individual's or a place's exposure to noise can be monitored. Sound measurement equipment is now so small that an individual can wear a small badge, known as a dosebadge which will record noise exposure over a period.
So where is this technology used? It actually has a surprising number of applications, the most common of which is in the workplace. Legislation exists to protect individuals from harm at work and in public, known as health and safety legislation. One particular aspect of this legislation is the Control of Noise at Work regulations 2005 which exists to protect workers from loss of or damage to their hearing through exposure to occupational noise. Industries which are commonly affected by excessive noise in the workplace include manufacturing, mining and construction. Sound measurement equipment is commonly worn by workers for the duration of their shift so that exposure to loud sounds can be monitored and prevented and reduced. Monitors may be used daily or only periodically but will always contribute to an employer's knowledge of how to best protect their workers' hearing.
Noise regulation also applies to the entertainment industry. Not only are workers protected but also members of the public. An example of this might be neighbours living near nightclubs or venues used for outdoor concerts. Their exposure to noise levels may be monitored with sound measurement equipment. In cases where local residents oppose planning applications relating to new entertainments venues, or even opening or widening of roads on the grounds that the associated noise levels are unacceptable, noise monitoring equipment might be used to gather evidence to help planners to make an informed decision.
Although normally the preserve of health and safety executive officers, sound measurement equipment is available to buy. It is also offered by many of the companies which manufacture it on a hire basis. This is especially useful for companies who may need to use the monitors but not on a regular enough basis to justify purchasing them. Similarly, the manufacturers of sound measurement equipment often also offer sound measurement training so that employers understand how to measure sound, why it is important to measure it and the ins and outs of their duty of care towards their employees so that health and safety regulations is complied with.
