The efficiency of an acoustic material is determined by measuring its absorption coefficient, denoted α. The absorption coefficient is defined as the proportion of acoustic energy that has been absorbed in the material over the total energy.

The static airflow resistivity (SAR), often represented by the Greek letter σ (sigma), is a very important parameter for acoustic material modeling. In fact, one of the first acoustic models presented by Delany & Bazley in 1970 [1] was only relying on this parameter.
Mecanum’s team will be participating at Internoise 2022 in Glasgow from August 21st to 24th as a sponsor! Come chat with us and discover our latest innovations. We will be presenting our new portable 3D acoustic camera among other products and we will be so happy to discuss your innovations as well!
An acoustic absorbent material is a material in which sound waves penetrate and then are dissipated. There are two main families of absorbent materials: fibrous materials and porous materials.
Mecanum Inc. is proud to announce the granting of a $ 150,000 grant which will finance the development of a thermo-acoustic insulating panel as part of the first phase of the Biofoam Insulation Challenge, aimed at developing greener insulation products. Sponsored by Natural Resources Canada, this challenge is part of the Domestic Plastics Challenge of the federal Innovative Solutions Canada (SIC) program.
Mecanum Inc. is proud to announce a $ 481,823 research grant from the Department of Economics, Science and Innovation (MESI) under the Research Support Program, component: Support for International Research and Innovation Initiatives (PSR-SIIRI). The goal is to increase the acoustic insulation of plane fuselage.
