and Vibration Metrology Division
Acoustics and Vibration
Metrology Division maintains a laboratorial and support infrastructure,
occupying an area of 1,166 square meters, which includes an anechoic
chamber , with a volume of 70 cubic meters , and two reverberant
chamber, one with 94 and the other with 210 cubic meters.
It comprises an adequate laboratorial
infrastructure with an anti-vibration suspension isolated room,
free of mechanical interference and endowed with climatization,
as well as physical installations capable of satisfying the requirements
of international rules. It comprises the following metrological
labs: laboratory of acoustics ; laboratory of electroacoustics;
and laboratory of vibrations.
The Division offers services of calibration
of specific instruments and of the standards of acoustics and vibration,
of which are demanded by laboratories accredited by Inmetro pertaining
to the Brazilian Calibration Network, the Brazilian Testing Laboratories
Network and also by laboratories linked to the Brazilian Network
of Legal Metrology and Quality (RBMLQ).
Among the innumerous measuring ranges, types of instruments and
associated uncertainties, the services offered
include: the calibration of microphones, accelerometers, acoustics
calibrators vibration calibrators, acoustics and vibration analyzers
and other specific tests.
