    Information relating to the training package, its key elements, requirements & means of certification.

    • Session 1: Introduction to Sound

      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.

      • Session 2: Measurement of Sound

        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.

        • Session 3: Measurement of Environmental Noise

          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.

          • Session 4: Calibration and Conformance Testing

            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 floors etc.).

            • Session 5: Case Study Environmental Monitoring

              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 be identified.

              • Session 6: Calculations

                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!

                • Essentials of Noise 1 Knowledge Check, Feedback and CPD

                  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.
