Primers & Handbooks

This booklet deals with environmental noise − for example, noise from industrial sites, road and rail traffic, airports and fairgrounds. It does not cover related issues such as building acoustics, building vibration or domestic noise.

This handbook gives an insight into the theory behind the development of microphones and preamplifiers and explains the terminology used to describe these products. The aim of this volume is to promote a full understanding of measurement microphones and to provide sufficient background information for customers to get the best out of these products. It also gives adequate information for customers to be able to make informed and qualified decisions about the microphone products which are most suitable for their measurement requirements.

This handbook contains specific information about Brüel & Kjær's Falcon™ Range of 1/2" microphone products. It contains a chapter on each of the microphones, a chapter on 1/2" Microphone Preamplifier Type 2669 which can be used with these microphones, and a list of the available accessories which can also be used with these microphones.

This booklet gives an introduction to the design features and operating principles of measuring microphones. Some knowledge about the measurement of sound would be an advantage and so you might wish to consult our companion booklets "Measuring Sound" and "Sound Intensity".

This booklet sets out to explain the fundamentals of sound intensity measurement. Both theory and applications will be covered. Although the booklet is intended as a basic introduction, some knowledge of sound pressure measurement is assumed. If you are unfamiliar with this subject, you may wish to consult our companion booklet "Measuring Sound".

This booklet answers many of the basic questions about occupational noise exposure and hearing conservation.

This booklet is an introduction to human vibration. It explains what is meant by human vibration; why we are, or should be, interested in human vibration; how it is measured and what action can be taken to reduce human exposure to vibration.

Modal analysis is an efficient tool for describing, understanding, and modeling structural behaviour. The study of modal analysis is an excellent means of attaining a solid understanding of structural dynamics. "Structural Testing" consists of a comprehensive introduction to the theoretical background to modal analysis and structural dynamics.

Modal analysis of the data obtained from structural testing, provides us with a definitive description of the response of a structure, which can be evaluated against design specifications. It also enables us to construct a powerful tool, the modal model, with which we can investigate the effects of structural modifications, or predict how the structure will perform under changed operating conditions.

The influence of acoustics on the design of buildings can be observed through the ages from Roman amphitheatres to the modern houses or buildings in which we spend our working hours and our leisure. The great difference, however, between life in ancient Rome and life in our crowded modern cities is the presence of noise from an ever increasing number of sources, from neighbours, traffic and industry.
