Acoustic Treatments - Genelec 8010 Setup Manual

Acoustic treatments

Monitor calibration alone helps but may not be sufficient to resolve room acoustic
problems.
Audio production rooms are designed for monitoring and should receive
adequate acoustic treatments to allow quality monitoring. Several room acoustic
improvements are suggested here. However, using services of a professional
consultant is highly recommended.
Wall surfaces, ceilings and floors can be reflective, diffusive or absorptive.
Combinations of these are often used.

Hard surfaces such as glass, concrete,
dry wall or MDF reflect sound.
Soft materials such as rock/mineral wool,
sofas, heavy curtains or thick carpets
absorb sound energy. Thick layer of
porous materials are needed to absorb
lower frequencies.
Irregular surfaces scatter sound waves.
Spreading angle depends on the diffusor
design. Diffusion is usually not effective at
low frequencies.
A combination of diffusive and absorptive
surfaces can be very effective in reducing
the audibility of reflections.
