CPD Dynamics Ltd Workplace Noise
HOME -measurement, analysis and control
A growing recognition of the importance of machinery noise in the workplace and in the environment, and product noise in the home has led to increased regulations and consumer awareness.

The Control of Noise at Work Regulations 2005, Environmental Protection Act 1990 and Pollution Prevention and Control Act 1999 are having a growing impact on a wide range of manufacturing and service industries. In addition, the Machinery Safety Directive, Physical Agents Directive and Noise Emission Directive will all require manufacturing industry to comply with new legislation.

A competitive edge is also gained by those manufacturers who address product noise as a commercial issue. A design for quiet operation is a design which sells.

The Course Due to the wide ranging nature of the subject, this course is offered on a company specific basis. Following initial discusions, a training package will be developed with a syllabus designed to meet the needs of the particular target audience. This flexible approach can incorporate both internal company presentations and external specialist expertise where appropriate to create an inclusive package.

The course provides an introduction to the subject of noise with particular emphasis on noise units, measurement and analysis techniques, the correct use of instrumentation, interpretation of results and basic noise control. A draft outline of a typical 2 to 3 day course is given below.

Emphasis may be placed on topics of particular interest to the company, and the duration of the course may be adjusted as appropriate. Comprehensive notes covering will be prepared and these serve as a valuable reference after the course.
