Noise Surveys

Noise Surveys

People don’t appreciate how important good hearing is until it is impaired.

Human hearing is damaged by excess noise and can deteriorate significantly if unprotected in a noisy workplace. A Hearing Conservation Programme is directed at identifying and quantifying the noise hazard, and then implementing all practicable steps to control noise and minimise its effects on health and hearing. This involves noise measurement, hearing testing, noise control by engineering or other methods, and hearing protection and education.

Noise Surveys

WOHC can help workplaces comply with the Health and Safety Regulations in relation to noise management. These regulations require any noise hazard to be surveyed using the services of a properly qualified person. We provide a full report which explains the steps that need to be taken to manage noise in order to comply with the law. The noise survey also gives workplaces the information needed to choose the correct type and class of hearing protection.

This is a survey of the work areas of the business assessing the levels of noise exposure in relation to General Risk and Workplace Regulation 2016. The assessment and report are undertaken by staff whom are qualified through the British Occupational Hygiene Society (BOHS) Noise Specialist – Measurement and its Effects issued by the BOHS Faculty of Occupational Hygiene.

A preliminary/walk through survey of common work sites is carried out to determine which areas have a potential noise hazard. This is followed by a measurement of an individual’s actual noise exposure measured by a Personal Dosimeter. The data from both the preliminary survey and the dosimeter is presented in a report that gives recommendations about what actions need to be taken to control employee exposure to the hazard.

Preliminary/Walk through Survey

The purpose of the walk-through survey is to identify what the indicative noise level is in various areas of the factory/work area. If hazardous levels of noise are indicated, dosimetry would be recommended, to determine the exposure level of one or more individual workers. The findings will be provided in a Preliminary Noise Report.


Dosimetry gives an accurate exposure level of the individual worker. This is required by regulation 10 of the Health and Safety in Employment Regulations 1995 to ensure adequate assessment of the noise hazard. If the results from the preliminary noise survey indicate a requirement for dosimetry in the factory area, a dosimeter would be placed on one staff member for the duration of their shift. The measurement obtained would indicate the personal exposure to any hazardous noise. The employees wearing the dosimetry equipment need to be onsite for the day. If any individual wearing the dosimeter vacates the site, this will affect the accuracy of the data for which WOHC HEALTH LTD will accept no responsibility.
