Treatment

Control sound inside the room

Absorbers, ceiling clouds, bass control and diffusion improve clarity and reduce excessive reverberation. These products do not automatically stop sound transmission to neighbouring spaces.

Isolation

Control sound through the room envelope

Mass, separation, resilient connections, sealed openings and controlled ventilation paths are required when sound must be contained or excluded.

Verification

Move from preliminary BOQ to approved design

Final systems require measured dimensions, construction details, target performance, service coordination, fire review and installation drawings.
