The problem it solves
Quiet offices are not always comfortable. In a very quiet room, every conversation, phone call and cough carries. People lose focus, and confidential talks in a clinic or HR office are overheard.
Sound masking raises the background level slightly in the right frequencies, so speech becomes less intelligible at a distance. Most people stop noticing it after a short time.
How a system works
- Emitters installed above the ceiling or in the ceiling plenum
- Cabling and zone controllers
- A central generator that produces the masking sound
- Zoning so different areas can be adjusted
- Tuning with a meter after installation
Where it is useful
Open offices benefit the most. Private offices, medical and dental clinics, legal and financial offices and meeting rooms near reception areas also see good results.
It works best with good acoustics: absorptive ceiling tiles, partitions that reach the right height and solid walls where privacy matters. Our interior systems crew, led by Brian Wright, builds walls and ceilings, and our low voltage team installs masking. Together they plan the overall acoustic result.
Installation and tuning
Emitters are placed on a grid pattern above the ceiling. Layout depends on ceiling height, tile type and open areas. Since our team also works with ceilings and lighting, we avoid conflicts with fixtures and ductwork.
Tuning is the key step. A technician adjusts levels and frequencies throughout the space. A poorly tuned system can sound like a hiss, while a good one is barely noticed. Retuning may be needed after furniture or layouts change.
Expect a period of adjustment. We suggest telling staff what the system is and why, since it can seem strange at first. We can also adjust levels after move-in based on feedback.
Sound masking can be added in renovations if the ceiling can be opened. Planning it from the start of a tenant improvement is simpler and cheaper. It also connects to the building's other systems, so volume can be scheduled or paging added where useful.
