Sound Absorption, Room Acoustics & Electroacoustic Systems

Broadband absorption across wall and ceiling surfaces

Use PET, fabric-wrapped and fiberglass panels, perforated or slotted wood panels, acoustic ceilings, suspended clouds, baffles and spatial absorbers where each surface can work effectively.

Treatment at primary reflection points

Prioritize ceilings, primary reflection points, parallel walls and high-energy zones; calculate treatment from room volume, use and source position instead of covering every surface and making the room unnaturally dry.

Balanced low-frequency reverberation control

Increase cavity depth and backing absorption, and add membrane or resonant absorbers where needed, to strengthen low-frequency control and keep reverberation balanced between frequency bands.

Beneficial musical reflections

In music, performance and multi-purpose rooms, retain beneficial reflections alongside reverberation control so sound keeps natural loudness, warmth and spatial character.

Useful early reflections from stage to seating

Place early-reflection surfaces near stages and lecterns to support performer ensemble, reinforce direct sound and improve listening from front to rear seating.

Diffusion for even sound-energy distribution

Use relief, folded, slatted or purpose-designed diffusers on audience side walls, rear walls and ceilings to distribute energy and reduce strong echoes, flutter, focusing and sound-shadow zones.

Control of parallel surfaces and strong reflections

Avoid large smooth parallel walls, uninterrupted glazing and concave hard surfaces; use variable absorption or adjustable reflection where different operating modes require it.

Room response resolved before electronic correction

Resolve reverberation, echoes, background noise and room-response defects through architectural acoustics before designing loudspeakers; electronic equalization cannot repair the room itself.

Controlled loudspeaker direction and coverage

Control loudspeaker directivity, coverage angle, position, delay and sound-pressure distribution to reduce wasted energy on walls and ceilings.

Microphones, processing, simulation and commissioning

Coordinate microphones, reinforcement, feedback suppression, digital signal processing and assisted-listening systems for clear speech, natural music and even seat coverage.

Simulate and detail acoustic materials, loudspeaker coverage and interior geometry together, then commission with reverberation, clarity, uniformity and sound-system tests.
