d&b NoizCalc is a specialised simulation tool designed to accurately predict the environmental impact of d&b audiotechnik loudspeaker systems in outdoor settings. Integrating data from the d&b ArrayCalc simulation software, d&b NoizCalc calculates sound propagation beyond the audience area and visualises this information using detailed noise maps. These calculations are based on recognised international standards for environmental noise prediction, providing system designers with critical insights into how sound behaves in open-air venues.

Primarily intended for use in the planning and evaluation stages of outdoor events, d&b NoizCalc supports complex configurations involving various d&b loudspeaker types, including line arrays, point sources, subwoofers, fill systems, and delay lines. It enables users to assess and refine loudspeaker placement and system settings to achieve desired coverage while managing sound levels at property boundaries or other sensitive areas.

Developed in cooperation with SoundPLAN, a leading environmental acoustics software provider, d&b NoizCalc offers a high level of predictive accuracy. This makes it an essential resource for audio professionals who are responsible for ensuring regulatory compliance, minimising off-site sound emissions, and optimising acoustic performance. As outdoor sound regulations become increasingly stringent, d&b NoizCalc helps stakeholders meet technical and legal expectations through data-informed design.
