Noise measurements in industrial facilities

Possible noise sources per sector:

  • production facilities, factories
  • construction equipment
  • load-handling equipment
  • single lines and equipment
  • ventilation and heating systems
  • various technological processes
  • other

More than 5% of the world's population (466 million people) suffers from hearing impairment - 432 million adults and 34 million children. It is estimated that by 2050 more than 900 million people (one in ten) may lose their hearing due to a noisy environment. Around 1.1 billion young people (aged 12 to 35) worldwide are at risk of hearing loss due to exposure to noise in recreation and entertainment venues. Experts from the World Health Organization have estimated that about 360 million people have moderate to severe hearing impairment due to various causes, including noise. According to them, it is possible to prevent half of all situations involving hearing impairment. Worldwide, the unresolved hearing loss problems cost $ 750 billion in health care costs, social costs, and disability costs. Not to mention the discomfort and other difficulties faced by people with such problems.

The following rights and obligations have been established for noise source managers:

  • planning to use stationary noise sources in their economic activities - must assess the impact of noise on public health and the environment, following the procedure, established by laws and other legal acts
  • planning construction, repair, installation works in residential areas - must provide the municipal authorities, not later than seven calendar days before the commencement of these works, with information about the place where noise sources will be used, the expected noise level and its duration per day and the noise reduction measures
  • compliance with the established noise limit values and ensure that the noise level of the equipment, engineering structures and systems which will be used in the economic activity, will not exceed the noise limit values set for the area where the noise sources are used
  • operating or carrying out economic activities in noise prevention zones approved by the municipal council:
  • must submit noise prevention action plans to the municipal administrative body within 30 days after the approval of these zones
  • must submit annual reports to the municipal administrative body regarding the implementation of noise prevention action plans.

According to LST ISO 1996-1: 2017, LST ISO 1996-2: 2017 and LST EN ISO/IEC 17025

  • we measure the noise generated by the equipment, line, workshop or the entire facilities
  • evaluate the measurement errors (uncertainty)
  • calculate and present the measurement results and errors (uncertainty)
  • provide the statements of compliance
  • provide the interpretations and opinions

We measure:

  • equivalent sound pressure levelLAeqT
  • residual sound pressure level LAresid
  • adjusted (recalculated) equivalent sound pressure levelLAeqTcorr
  • maximum sound pressure level LAFmax
