Acoustics Testing Service
A national centre for acoustical
services with ISO accreditation
We are surrounded by the science of acoustics – from shopping malls, homes and
schools to music, medicine and industry.
Acoustics plays a key role in how well we speak and hear in
these environments, from the level and type of background
noise, to the type of insulation used. It’s also important in
understanding how well the structures themselves perform.
At The University of Auckland, the Acoustics Testing Service
(ATS) both tests and researches this interdisciplinary science
to find out how best to manage acoustics – the mechanical
waves in gases, liquids and solids that range from vibration and
sound to ultrasound and infrasound.
ATS is an independent research based
facility that can help your organisation
with:
Reverberation chamber wall test facility
•
Testing the acoustical properties and performance of new
materials, constructions and equipment
Customised facilities
•
Sound measurements (in classrooms, rest-homes, theatres)
•
ATS is home to three reverberation chambers, an IEC listening
room, and an anechoic chamber.
Services to acoustical consultants
•
Research and development of acoustics and noise control
•
Equipment testing for hire
•
Developing sustainable practices around acoustics in urban
design and planning
•
The three Reverberation Chambers are linked by heavy steel
doors and a removable standard concrete floor section. The
three chambers are vibration isolated from one another so
that sound can only pass from one to the other via the test
wall, or test roof/floor section.
•
Removable concrete floor section
Reverberation and Anechoic Chambers. These facilities
were specially designed for acoustical testing to international
(ISO) standards of building materials, sound producing
machinery and audio equipment.
Listening room. Fully compliant with International Electrotechnical Commission (IEC) specifications, the Listening
Room was developed specially for subjective hearing in
domestic environments. All testing and measurements are
computer-controlled with testing accuracy maintained at the
level required for international laboratory accreditation.
ATS has particular expertise in the areas of testing
building insulation, floor ceiling constructions with
improved impact insulation, and the acoustics of
teaching spaces with special applications in primary
schools.
Acoustics is now an integral part
