Technical Clarifications

Frequently Addressed Sound Engineering Questions

Essential information regarding our acoustic testing methodologies, hardware interoperability, and consultation procedures.

An on-site audit begins with calibrated 3D room impulse measurements using omnidirectional sound sources and calibrated measurement microphones across multiple listener positions. We evaluate reverberation decay curves, early-to-late sound ratios (C80/C50), lateral energy fraction, and background noise criteria (NC/NR ratings) to generate an actionable optimization report.

We design and calibrate concert sound systems using cardioid array geometries and beam-steering algorithms to maintain compliant $L_{Aeq}$ and $L_{Cpeak}$ levels at venue boundaries while delivering high dynamic range and pristine clarity across the audience zone.

Yes. We specialize in designing transition architectures from legacy analogue multi-cores to redundant Gigabit Dante and AES67 IP networks, preserving operational reliability while expanding multi-channel routing capabilities.
