This session will review the basic theory of
sound. It will cover the sound pressure,
sound power and sound intensity measurement types and their respective uses, it
will also deal with wavelength, frequency, measurement time weightings and the
effects of this on propagation and measurement. There be an opportunity to carry out a
number of brief experiments to illustrate the theory and link this to the
practical knowledge necessary for regulatory enforcement of noise.
This session will look at
noise measurement and instrumentation types, uses and standards.
Types of sound level meters for measurement of sound levels in different
environments and for different purposes.
The session will explain frequency weightings and time weighting
(‘Fast’, ‘Slow’, ‘Impulse’ averaging times) and their uses, how they affect
environmental measurements. This session
will review a number of case studies to illustrate the key points.
This session will focus
on environmental measurement in accordance with British Standards (in
particular BS 7445 Description and measurement of environmental noise) and
Uncertainty in sound level measurement.
This key session will help provide an understanding of context in review
of sound level measurements and identify how the results may be best displayed.
This session identifies
the basic calibration testing requirements and the standards required for sound
level meters to carry out accurate and reproduceable environmental measurements. It will also cover what to look for in
instrumentation that shows there may be a problem. And discuss the concept of
selection of the correct instrumentation for the measurements required (noise
This session will provide
delegates with an environmental report for measurement of noise. The report will be reviewed, and the errors
(or omissions) within it. It will also
provide an opportunity to review the report for possible enhancements that can
Based on session 5 we
will review some of the basic calculations that can be used to manipulate
measured noise levels. Including adding
and subtracting sound levels, time correcting and distance correcting measured
levels, and conversion of sound pressure to sound power. And yes you will need a calculator!
The Noise 1 Knowledge Check will enable you to review your understanding of the course material from the 6 sessions across Noise 1.
Participants will have three attempts at the Knowledge Check and a score of 75% is required to pass.
