Statistical pass-by (SPB) measurements [1] can be used to determine the absolute emission level for a location on a road and close-proximity (CPX) measurements [2] can be used to determine the homogeneity of the road. However, the acoustic condition...

Airborne sound measurements were carried out to determine the emissions of electric cars and to assess the acoustic impact of the electrification of a given composition of conventional and electric cars. The results show that, as expected, the noise...

Baffle absorbers (several sound absorber panels suspended vertically in the room, usually positioned in parallel rows under the ceiling) are used to optimize room acoustics. The sound absorption of a baffle absorber depends not only on the absorber...

Traffic noise is one of the most significant categories of noise exposure that can be associated with negative health effects. Due to increasing urbanization, more and more people are affected by traffic noise, whose quality of life is impaired as a...

The Federal Institute for Occupational Safety and Health (BAuA) provides the Sound Prediction App (SPA), a practical tool that is available free of charge for simplified sound prediction in workspaces. The software facilitates the estimation of...

A feasibility study was conducted to investigate the extent to which a swarm of drones equipped with microphones can be used to locate and map noise sources. The aim was to supplement traditional stationary and partially calculation-based noise...
