Acoustics

• 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
