d&b’s new software tool NoizCalc, introduced at Prolight + Sound 2016, enables system designers to assess how multiple complex and coherently emitting sources (like d&b line arrays and subwoofers) will impact on areas outside the listening field. It’s a significant enhancement in the prediction and planning toolbox for existing d&b systems. NoizCalc was created in collaboration with noise consulting and software development experts, SoundPLAN.
The software works by taking data from d&b’s ArrayCalc simulation software and calculating snapshots to show the sound propagation and relative attenuation values towards the far field for a certain scenario. The results are displayed on a 3D terrain map showing the calculated emission on the areas surrounding the audience listening zones. The graphic representation of the system’s output lets users optimise for listeners while satisfying local noise restrictions and offsite regulations.
Sabina Berloffa, Director of Marketing and Product Management at d&b commented: “The response to NoizCalc has been striking and testament to this much needed technology. We’ve known for some time that managing far field noise emission has been a growing issue and as a trusted manufacturer in this market we felt a responsibility to help address the problem. d&b has a thirty five year history with large scale outdoor productions and their distinct needs. Today, that means sonic excellence for listeners and performers, but equally crucial is minimising noise disturbance in the surrounding area — the future of open air events depend on it.”
NoizCalc is available for download from the d&b website.
