Far field noise calculation software is the next step in the d&b audiotechnik enabling technology portfolio

It’s tried and trusted that a d&b audiotechnik loudspeaker system is more than the sum of its parts. So what’s new at Prolight + Sound 2016?

d&b is introducing NoizCalc, a new software tool to predict the far field noise immission of open air events. Noise from outdoor entertainment events has become a serious topic, particularly as the number of events in populated urban environments increases. Gaining permission to stage an event frequently requires an official statement with a prediction of the noise impact on the surrounding areas.

NoizCalc is designed by d&b in collaboration with noise consulting and software development experts SoundPLAN GmbH, as the next tool in the d&b enabling technology portfolio. NoizCalc predicts sound propagation of multiple coherently emitting sources such as line arrays and subwoofer arrays. Using 3D terrain data the software accurately predicts the far field noise immission across the terrain according to ISO 9613-2 and Nord 2000 standards, allowing system designers to predict any potential noise issues during the event planning stage.
