EASE Acoustic Modelling

EASE modelling builds a geometric and acoustic model of the venue and simulates the real system inside it. Using manufacturer GLL loudspeaker data we map sound-pressure coverage across the audience, predict STI / %Alcons seat by seat, and test direct-to-reverberant ratio and arrival times. The model answers the questions that cost money to get wrong on site: which loudspeaker, mounted how high, aimed at what angle, with which delay and EQ.

Because the model uses measured loudspeaker balloons and the calculated room acoustics, it exposes problems early — uneven coverage, intelligibility holes under balconies, comb filtering from overlapping sources, feedback-prone microphone zones. We iterate on aiming and product choice in the model until the coverage and STI maps meet the target.

For voice-alarm and public-address systems the same model documents that the design meets intelligibility requirements, which matters for sign-off under EN 54-16 / EN 60268-16. The deliverable is a decision tool with maps and a parameter set the installer can dial in directly.

Deliverables

• 3D acoustic model
• SPL coverage maps
• STI / %Alcons maps per zone
• loudspeaker selection, height & aiming angles
• delay/EQ strategy
• auralisation on request
• intelligibility compliance documentation.

Workflow

Why Acoustic Delta

Acoustic Delta keeps acoustic targets, system design, documentation and commissioning in one engineering workflow, so the installed result can be checked against measurable criteria.
