LSD is also the coverage
area for one loudspeaker
For small rooms such
as bathrooms, you may
only need one or two
loudspeakers to cover the
room; look at LSD

Multipliers are created from Coverage Angles (CA). These are multipliers we have found to work for most
applications. For more precise results, and to adjust for obstructions, use Bose Modeler, EASE, EASE
Address, EASE Evac, or another calculator.
Edge-to-edge coverage can provide fidelity in fixed-location seating/standing and can generally work well
for installations on a budget. It also works well for ambient-level and low-level background music. Center-
to-center installations will have higher density and can accommodate people listening in many dierent
positions and moving floor plans due to uniform coverage. They will also have fewer dead zones. Minimum
overlap (or center-to-center) may also be needed if critical communication is happening over the system.
Bose Modeler or EASE Evac can help with speech intelligibility evaluation.
B. Place the first loudspeaker at ½ LSD from any corner of the room.
