Acoustic Laboratory

The Technical and Test Institute for Construction Prague (TZÚS Praha, s.p.) offers the services of the unique LASA building acoustics laboratory, which provides acoustic testing in accordance with European standards. The modular system of attaching samples to the test apparatus enables very fast and flexible testing of large numbers of samples.

Building acoustics

Sound insulation measurement of structures in accordance with international standards; verification and final approval measurement (partitions, ceilings, windows, doors, building envelopes)

Measurement of sound insulation of products, components and parts of structures (glazing, windows, doors, skylights, DRw ETICS)

Measurement of acoustic effects of barriers against traffic noise

Measurement of physical-acoustic parameters of building sound insulation products and sound absorbing products (sound absorption and resistance to airflow)

Theoretical calculations and predictions of sound insulation
