An introduction to monitoring noise |

Monitoring the
noise levels in the Workplace General monitoring of the noise levels where people work will give the industrial hygienist a good picture of the likely risk around noisy plant or machinery. Go straight to suitable products > |

Personal Noise dosimetry Personal noise dosimetry can be carried out on individual workers to see exactly what their noise exposure is for their own working day. This involves the monitoring instrument being placed on the individual to collect the different contributions from all the potential hazardous noise sources during the work day.

Choosing hearing protectors Of course measuring the noise exposure may be only part of the problem. Where high noise exposures are identified some form of personal protection will be needed while engineering measures are put into place. Ear plugs and ear muffs must be correctly specified to be effective.

Community noise
assessments Loud parties and other social gatherings can be a nuisance to neighbors where inappropriate behavior goes on. Noise levels that are not dangerous can still annoy others in the wrong location and at the wrong time of the day. Go straight to suitable products > |

Transportation noise measurements Almost all of us are affected by the increasing numbers of vehicles on our roads. Many of us live near to airports or train lines. The pace of life today means that transportation noise is an intrusion into everybody's life either at work or at home or sometimes both. Go straight to

Short
term noise measurements For a number of noisy sources measurements can be made quite quickly, the chiller on the roof, the air conditioning plant or the noisy muffler on a passing motorcycle are such examples where simple hand held measurements usually suffice to give a good representation of the problem.

Long
term noise measurements Living around a busy airport, however, means that longer term studies over perhaps weeks or even months may be in order to correctly categorize the true noise climate and compare with planning limits or zoning requirements. Go straight to suitable products > |

Product noise
assessments Nobody wants to buy noisy products for their homes and nobody would think twice about introducing noisy machinery into their plant when they are trying to reduce worker's exposure to dangerous noise levels. We all want to receive less noise from the items we buy compared to the existing ones we currently use. The sound power of a noise source is often used to predict the likely noise levels that can be expected in certain environments.

Sound quality
measurements How loud is loud? And how acceptable is one noise compared to another? The quality of a sound is part of the design of that product and we expect certain things to sound "just right". But how do we know when we have it right and acceptable to the likely customers of that particular noise source? Sound quality measurements can help to design the right product from the beginning instead of stumbling on it by accident.

Building
acoustics measurements The sounds that we hear are not just the result of the noise source. The environment that we hear them in is important in how a certain sound is perceived. Everyone knows that singing in a bathroom sounds completely different to singing in a room with softer wall and floor coverings. Building acoustics measurements enable us to characterize how sound will behave in an enclosed space such as a cinema or theater or a school classroom. Go straight to suitable products > |
