Mechanical Engineering Acoustics & Noise Unit
The Mechanical Engineering Acoustics and Noise Unit (MEANU) was founded in 1984. It has the distinction of being the only full-scale Canadian acoustics laboratory directly associated with a university and, therefore, allows for educational and research use of the facility along with commercial testing. MEANU functions under the Department of Mechanical Engineering, which simplifies access to facilities in the Department.
It has become one of two active laboratories in Canada which carry out standard American Society for Testing and Materials (ASTM) and International Standards Organization (ISO) testing for acoustical materials and systems. Projects such as standard acoustic tests, research contracts or fundamental research can be developed and completed. Consequently, MEANU offers an excellent vehicle for technology transfer between the University, regulatory agencies and the commercial sector.
General Description of the Facilities
The major portion of the facility is contained in a laboratory/office located in south-east Edmonton. The layout of the MEANUS's test chambers is shown on the floor plan (shown at bottom of page) and includes two inter-connected reverberation chambers in which much of the sound transmission, sound absorption and sound power testing is done. The control room uses a digital filter based computerized data acquisition system to automatically measure, record, and process the acoustical data efficiently. The major concern is to obtain precision, which meets or exceeds the requirements of the appropriate testing standards.

Details of Specific Testing Capabilities
MEANU conducts standard tests to provide clients with specific information. These include:
  • Sound Absorption and Sound Absorption Coefficients by the Reverberation Room Method (ASTM C423).
  • Measurement of Airborne Sound Transmission of Building Partitions (ASTM E90).
  • Field Tapping test (ASTM E1007).
