DOOR WINDOW
A door window is provided with each WhisperRoom.
Multiple layers of 1/4" thick laminated safety glass are used.
Laminated safety glass is used because of its superior noise reduction capability and safety features.
If broken, it will not shatter! Air buffers are also built into the windows.
This, and the fact that the weight/sqft of a window exceeds that of a solid
wall component, helps to prevent noise transfer. The door window does not
reduce the noise reduction capability of a WhisperRoom. It does, however,
increase the amount of interior reflective surface area.
The chart below shows the difference between STANDARD and ENHANCED door window designs.

LIGHT
Lights shipped with WhisperRooms are
intended to provide customers with basic startup lighting. It is understood that most customers
will ultimately purchase and install lighting fixtures more suitable to their individual needs
and desires. One or two lights are provided, depending on the enclosure size.
Note: Lights are UL approved.

CABLE PASSAGE PLUG
Access for communications (microphone, headphone, speaker,
etc...) and electrical cables is accomplished by way of slotted rubber plugs.
Simply remove a plug, insert the cable and re-insert it into the wall. Two or
more cable passage plugs are provided with each WhisperRoom and each will
accommodate multiple cables. The number of plugs depends on the size of the
unit. Also, an additional cable passage plug is located at the base of each
optional window component.

ACOUSTICAL FOAM
The entire interior surface of each WhisperRoom ceiling
component and the base of the door are covered with pre-attached acoustical
foam wrapped with cloth.
Additional acoustical foam sheets ( 2' x 4' x 2" thick / weight of
2 lbs/cuft) with a pyramid design, are provided for the interior of each
WhisperRoom. The number of sheets provided depends upon the size of the unit. Velcro
strips are supplied for non-permanent attachment to the walls. This allows
the user to tailor the interior acoustical environment to get the desired
sound.

VENTILATION
Effective air circulation is accomplished by acoustically engineered, detachable ventilation systems.
Each system circulates air at a rate of 100 CFM (cubic feet per minute).
The number of systems required depends on the size of the WhisperRoom unit. Each system mounts to an exterior wall surface
and includes one(1) intake duct, one(1) exhaust duct and one(1) Remote Fan Unit (RFU). Each duct contains a series of baffles and
acoustical foam wedges. This provides a treacherous path for sound to pass, while at the same time, allowing smooth air flow.
To minimize vibrations, the RFU is non-rigidly attached to the exhaust duct by a flexible ducting hose.
Fresh air is pulled into the room at floor level as a result of warmed air being pulled from the room at ceiling level.
A wireless remote switch is provided with each WhisperRoom to control the
ventilation system(s).
Standard ventilation systems are quiet. However, the fan
noise is still slightly audible inside the WhisperRoom.
If extremely quiet ventilation is required, Optional Ventilation Silencing Systems (VSS) are available.
NOTE: Although we highly recommend that
ventilation be included with each WhisperRoom, we understand that certain
applications may not require it. For those situations, we offer units which
are pre-configured for, but which do not include ventilation. If desired,
one or more ventilation systems can easily be added at a later date.
