Testing Laboratory for Technical Acoustics - Noise and Vibration Measuring

The Testing Laboratory for Technical Acoustics - Noise and Vibration Measuring is part of the Testing Laboratory No 1025 accredited by CIA (Czech Accreditation Institute). 

The testing laboratory of technical acoustics is equipped with the devices of the company Brůel & Kjaer – Denmark (Investigator 2260, multianalyser PULSE 3560-B-110) performs noise measuring and assessment in the working environment for the purposes of work categorization, and in external environment according to the Law No 258/2000 Coll., as amended by valid regulations.  Further, it performs measurement, evaluation and assessment of noise and vibration of machines and devices, hand-operated pneumatic tools and other machine units in open-cast or underground mine operations. It provides expert services in area of technical acoustics which have the character of complementary activity of the testing laboratory (proposals on noise-proof measures, expert opinions).

The measuring and assessment of noise and vibration is performed according to the valid harmonized standards and Government Directive No 148/2006 Coll.

ACTIVITIES
