In modern architecture, building acoustics play an increasing role. Not only the noise level is important but also the direction where the sound is coming from and the distribution of sound sources in the building have to be considered. For concert halls, sports stadiums and the like, acoustic properties are an integral and important part of their overall design. The Acoustic Camera is a valuable tool to measure, optimize and verify the acoustic properties of any building. Another important aspect of building & structure acoustics is condition monitoring and maintenance. With increasing traffic, adverse environmental conditions and more extreme weather, buildings and structures like bridges have to be closely monitored to maintain their stability and save function.
