ACOUSTICS
CONTACT FOR SUBSTANTIVE MATTERS
CONTACT
We perform tests of:
-
properties of insulation materials;
-
acoustic insulation against air-borne sounds and noise impact of construction components and building envelope elements;
-
sound absorption coefficient of materials and sound-absorbing systems;
-
coefficients of acoustic evaluation of road noise barriers;
-
dynamical stiffness of elastic materials used in floating floors;
-
resistance of the flow of porous materials;
-
reverberation time and parameters characterising reverberation conditions in rooms with qualified acoustics (e.g. speech transmission indicators, early fading time, sound clarity indicator);
-
noise level (sound pressure and “A” sound level) in the rooms and in the environment, including noise from road traffic, railway traffic, aircraft traffic and industrial plants
-
efficiency of acoustic protections
-
sound power level of machines and devices
-
directional characteristics of sound noises.
We test acoustic parameters under laboratory and field conditions.
We test the following acoustic conditions:
-
in residential buildings, boarding buildings and public buildings, including technical rooms, systems (central heating and hot water, ventilation, lifts) and other components constituting technical infrastructure of the building
-
in rooms with qualified acoustics
-
external environment.
