BENEFITS OF LONG-TERM MEASUREMENTS FOR THE CUSTOMER

Noise

 

AuresSound® is suitable for a wide range of noise measurements, whether it is about protecting workers from dangerous noises (85/2006), noise measurements according to the Housing Health Ordinance (545/2015) (Chapters 11-13) or environmental noise measurements according to Government decision 993/1992 (guideline 1/95 set by Ministry of environment)

 

Case study

 

In norther Finland, a large industrial area wanted to find out whether its guideline values in Government decision 993/1992 had been met. In particular, the possible spread of noise from the factory area to nearby holiday settlements was taken into account in the measurement setup. Noise was measured in both the factory area and residential areas at several points for two weeks. When analyzing the results, individual noise sources were also identified from factory operations, which were particularly well heard in holiday settlements. This information can also be used for condition monitoring as abnormal noise is often a sign of problems in the machinery. However, the target values set for the factory were met most of the time.

The benefits of long-term measurements for the customer:
  • variation of noise levels at different times: day vs. night, week vs. weekend

  • the effect of different production operation situations on noise levels

  • the effect of different wind directions on noise in the neighborhood

  • possible machinery faults, e.g., fans

Fine particles

 

AuresAir® is suitable for both indoor and outdoor PM2.5 and PM10 particle determinations. These measurements are guided by e.g., Housing Health Ordinance (545/2015,19§) set by social and health Ministry, and Decree on air quality (79/2017,4§) set by Government. In addition, AuresAir® is suitable for monitoring target values for particle concentrations in indoor climate classification.

 

 

Case study

One rock crushing plant needed to find out whether the limit values for small and respirable particles set out in Government Decree 79/2017 were met. The crushing plant was located between the highway and the residential area. AuresAir® devices based on light scattering were used in the measurements. The measurements were used to determine PM10 and PM2.5 concentrations from several sites for two weeks. After two measurement weeks, a report was created to investigate the share of crushing plant at different measurement points by comparing the measurement results and times at different measuring points. As a result of this report, the crushing plants operating methods were changed to produce fewer particulate emissions.

The benefits of long-term measurements for the customer:

  • variation of particle levels at different times: day vs. night, week vs. weekend

  • the effect of different production situations on fine particle levels

  • the effect of different wind directions on particle levels in the neighborhood

  • possible abnormal situations: e.g., traffic, process disruptions, time of the year

  • hygiene at work, comparisons to limit values.
