BUILDING ACOUSTICS

  • measurements of air-borne sound insulation and impact sound insulation in buildings
  • measurements of air-borne sound insulation of facades as well as individual elements - for instance windows in a building by means of two-channel technology - NEW
  • determination of sound proofing of cabins - in situ measurements, identification of acoustically weak spots - NEW
  • assessment of designed building structures with respect to the requirements for air-borne sound insulation and impact sound insulation in accordance with the ČSN 73 0532 standard

TRAFFIC NOISE

  • measurement of noise from road, railroad and air traffic - probes during day and night, 24-hour measurements
  • in situ determination insertion loss of exterior noise barriers of all types
  • measurement of the impact of road surfaces on traffic noise
  • traffic noise analyses - assessment of gas stations, parking lots, round-abouts, etc. - in the environment of the HLUKPLUS programme
  • design of noise barriers and walls including optimisation of wall type, shape, length and height

STATIONARY NOISE SOURCES, NOISY PLACES

  • hygienic measurements in non-working environments - measurements of stationary noise sources (ventilators, cooling units, compressors, elevators, etc)
  • assessment of noise levels within the surroundings of noisy places (discotheques, rock clubs, open-air cinemas, winter sport stadiums, manufacturing premises - as relates to the nearest protected (residential) buildings - based on direct measurements as well as computer simulation using HLUKPLUS

CONSTRUCTION NOISE

  • construction noise analyses by means of the HLUKPLUS programme

INDUSTRIAL NOISE

  • hygienic measurements in work environments - within an employee's reception zone, determination of equivalent level of sound pressure over a entire shift, etc.
  • technical measurements of manufacturing equipment inside and outside production buildings - measurements may be used to design measures to reduce noise level as well as to computer-simulate measurements in different venues
  • staff categorisation - in compliance with Section 37 of Act n. 258/2000 Sb., proposal to include work activities in categories under Section 3 of Regulation n. 89/2001 Sb.
  • based on technical measurements, identification of dominant noise sources both inside and outside production buildings
  • proposing measures for noise sources as well as for the building space, verification of acoustic effect by computer simulation
  • assessment of noise levels inside production buildings - based on direct measurements as well as computer simulation in IZOFONIK and VIZOFONIK environments
  • assessment of noise levels in workplaces outside buildings - based on direct measurements as well as computer simulation using HLUKPLUS

ACOUSTIC LEVEL MEASUREMENTS

  • acoustic level measurements - NEW
  • localisation of noise sources, mapping sound fields by means of intensity probes - NEW
  • identification of acoustically weak spots, transmission leaks, "latent" peripheral transfers - NEW
  • determination of sound power levels of noise sources by means of intensity probes - NEW
  • measurements of sound power levels of home appliances and noisy equipment operated outside (in accordance with Government regulation n. 9/2002 Sb.)

SPECIAL ACOUSTIC MEASUREMENTS

  • measurements regarding sound power of ventilators for type-testing
  • measurements regarding sound power of air-conditioning units for the manufacturer's catalogue sheets
  • searching for manufacturing defects in a series of products by means of frequency analysis and sound recording
  • measurements regarding sound power level of fume silencers
  • impact analysis of judder bars ("sleeping policemen") in the situation of both planned and existing locations

COMPLETION OF ACOUSTIC MODIFICATIONS

  • sound insulating fore-walls, dry-wall non-load bearing walls, metal encapsulation, covers, operator cabins, silencers
  • sound absorbing grid ceilings, baffles, cylinders
  • sound absorbing wall tiling, special tiles
  • acoustic sinus-shaped as well as straight wall covers for offices (combined pre-stretched metal and wood) - NEW
