Activity of the Division of Applied Vibroacoustics focuses on the two following subjects:

• research,
• designing of buildings, objects and equipment.

In the research area we offer:

• acoustic analyses, ecological audits as regards acoustic impact,
• analyses of vibrations,
• numerical models of land and GIS technologies,

• modelling of acoustic field in the environment and closed spaces (with determination of impact range and identification of sound sources),
• concepts for reduction of sound emission and mechanical vibrations,
• forecasting of changes in acoustic climate,
• acoustic maps and programmes for protection of environment against noise,
• vibroacoustic diagnostics as well as assessments of exposure of building/engineering objects to mechanical vibrations.

In the designing area we offer:

• functional-and-spatial programmes,
• designs as regards control of vibroacoustics hazards, including:

-    acoustic screens,
-    sound absorbing-and-isolating shields and casings,
-    silencers,
-    sound absorbing-and-isolating and lector cabins,
-    vibroisolation of objects, machines and equipment,

• designs as regards foundation of machines,
• designs as wellas design-and-construction projects,
• cost calculations and construction take-offs,
• scheduling of construction work,
• supervision over the realization of investments.

We also realize trainings and promotional activity as regards control of noise and vibrations emission.
