一般說明

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.

練習和指導練習

手册中包含的指导实践练习

  1. Study and investigation of the relative acoustic properties of different materials.
  2. Determination of the sound absorption coefficient for many of the normal building lining materials such as carpet, cork, fibre board and many of the better acoustic attenuating materials.
  3. Determination of the sound absorption coefficient of the these and some poor absorbers at a range of frequencies between approximately 300 and 4000 Hz.
  4. Determination of the speed of sound in air at ambient temperature and comparison of this with the calculated value.
  5. Sensors calibration.
