d&b expands ArrayCalc audio simulation software with HeadroomCalc

d&b audiotechnik’s HeadroomCalc will make its InfoComm debut at the 2023 Orlando show on June 14.

Exhibiting on stand #5561, the audio manufacturer will demonstrate how HeadroomCalc, the latest update to its ArrayCalc simulation software, can predict the reaction of a d&b system to a specific audio signal.

Available in ArrayCalc V11, HeadroomCalc provides a precise sound pressure level (SPL) and headroom calculation offering what d&b claims is a “superior and more comprehensive predictability of system performance”.

The patent-pending tool supports health and safety compliance at live events, ensuring sound systems stay within specified sound exposure levels. Pre-recorded alarm messages can be reproduced with a certain SPL.

HeadroomCalc predicts the reaction of a d&b system to specific audio signals, providing a more precise SPL calculation by processing any user-defined audio file through a simulation of the configured audio system. The input signal, often a pre-recorded alarm message or a recording of a band, is fed into the simulated loudspeaker processing of the selected d&b system amplifiers with intermediate results of output voltage and gain reduction signals for every amplifier channel within the system over time. The output voltages are combined with the simulated impulse responses of the connected loudspeakers. This yields the sound pressure signals for every loudspeaker at up to five individual definable receiver points.

The total sound pressure signal is created for all receiver points, which is the sum of all sound pressure signals at each point. This is then used to derive the SPL metrics in the same manner a portable SPL meter would operate at each defined measurement point.

d&b audiotechnik can be found at InfoComm Orlando on stand #5561 and demo room W230D. The trade show runs June 14 – 16, 2023.
