Noise

1. Noise The 2005 Noise regulations replace the 1989 Noise regulations and have reduced the level of noise at which employers need to take action. They refer to daily or weekly exposure and “peak sound pressure” (psp) which usually refers to a loud temporary noise such as a bang. The regulations indicate the action that should be taken within certain values which they call “exposure action values” These are as follows:- • Below Exposure Action Value 80 dB (psp 135dB) No action is needed except to monitor any changes. For example, new machinery may be noisier than 80 dB and would therefore need the action required in the next level • Between Lower Exposure Action Value 80dB and Upper Exposure Action Value 85dB (psp 137dB) If exposure to the noise at this level cannot be eliminated, suitable hearing protection should be made available to all staff who request it  • Above Upper Exposure Value 85 dB Employers should introduce control measures to eliminate or reduce this level of noise (e.g. sound enclosures) If, however, it is unavoidable that employees are exposed to this level the regulations make it mandatory that they should wear suitable ear protection. The regulations also require hearing checks for all workers who are regularly exposed to noise of 85dB and above. • Exposure Limit Value 87dB (psp 140dB) Workers should not be exposed to noise above this level 87dB 85dB 80dB >80dB
