Description
This unit has been designed to provide students with an easy and simple method for understanding and investigating the relative acoustic properties of several materials. It demonstrates acoustic attenuation of a range of building materials as carpet, cork and fibre board.
The unit is very useful for the teaching of students in different areas as: Sound and Vibration, Mechanics, Aeronautics, Building, Architecture, Health and Safety, etc.
An acoustic standing wave unit driven by two loudspeakers and a separate console mounted power amplifiers.
A small microphone traveling in the transparent plastic tube allows the acoustic signal to be fed to the console mounted microphone amplifiers.
The transparent plastic tube combine with a scale and marker allow the microphone axial position to be measured.
Several test samples allow a wide range of tests on differing materials. This unit is supplied with the necessary instrumentation and sensors for controlling and measuring the most representative parameters.
