We at Aircoustics, provide a full range of building acoustics field testing services to benefit the residential and commercial clients.
Using the most current ISO and/or ASTM standards, as well as industry-leading equipment, we perform building acoustics measurements throughout the MENA Region.
We work with builders, developers, and architects to verify that building partitions meet their required field values.
The most common building acoustics testing services that we offer are:
ASTC – Apparent Sound Transmission Class – is used to determine the airborne sound transmission values of wall and floor partitions. This testing has implications for secure areas, as well as for general residential or commercial use buildings.
AIIC – Apparent Impact Insulation Class – is used to determine the structure-borne (impact sound) transmission of floor partitions. This testing is most often performed in a residential setting.
OITC – Outdoor-Indoor Transmission Class – is used to determine the airborne sound transmission of the exterior facade of building elements, such as walls, windows, and roof partitions. This testing is often performed on buildings that must be proven to be secure areas, as well as general residential or commercial use buildings.
RT- Reverberation Time – is used to determine the length of time that sound takes to decay within an enclosed space. This testing is always performed in conjunction with ASTC, AIIC, and OITC testing, as it is an integral part of the calculation when performing those testing protocols. It can also be performed to determine the suitability of a room for a particular task. Long reverberation times are pleasing in a concert hall (for example) but harmful to speech intelligibility in a classroom.
Airborne Noise Measurement – is used to determine the Noise Levels (decibels (dB)) inside the spaces and actual distribution of frequencies. Typically, the airborne sound might be generated by:
Vibration Testing – which is used to determine vibration from building systems, especially HVAC equipment and Generators. This testing is often performed to evaluate the equipment base’s vibrations and induced in structure through short-circuiting (poor vibration isolation system).
Sure, you can measure noise (of all kinds) with your iPhone or Android phone. That may (or may not) tell you something regarding your facility or area’s noise level. The truth is, though, that is not the whole picture.
What is really important is the actual distribution of the frequencies.
That is where spectral/spectrum analysis comes into play.
We can measure in 1/1 or 1/3 octaves the actual noise levels from 8 Hz on to the 20 kHz band
When Aircoustics appointed at early in the planning process during development or amendments to an Official Plan, or a proposed re-zoning, we provide the study taking the form of a noise feasibility study, evaluating the broad compatibility of locating certain competing land uses adjacent to one another – such as a residential zone next to an industrial zone. Often, these preliminary studies are primarily predictive in nature because the lands in question may be only minimally developed or slated to change land uses. In this case, acoustic computer modeling is used to determine the future sound levels.
Once the existing and future sound and vibration levels at the development site are predicted/known, we determine the applicable assessment criteria. These limits could be set by the municipality, local/federal authorities, or best practices, depending on the jurisdiction.
We investigate acoustic matters on behalf of clients, providing technical advice and preparation of reports for submission in evidence as well as appearing in court as an expert witness. We also undertake employee noise exposure surveys in cases involving work-related noise-induced hearing loss claims.
