FAQ – Frequently Asked Questions

WhisperRoom™ has satisfied the needs of thousands of clients over the years. We have always offered high quality, effective, sound isolation enclosures at very affordable prices. The best testimonial as to the quality of a product, and integrity of a company, is a repeat client. Not only do our clients consistently speak highly of both the WhisperRoom™ product line and client service, many are repeat buyers, see our repeat clients page to see the list of clients that have come back to WhisperRoom time and time again for their sound isolation needs.
WhisperRooms are available in two levels of isolation, “Standard” and “Enhanced.” Standard units have a single-wall system. Enhanced units have a double-wall system and are suitable for applications which require a much greater noise reduction capability. Client needs dictate which would be required. Also, a Standard, single-wall, system can initially be purchased and later upgraded to an Enhanced, double-wall, system by installing the appropriate Isolation Enhancement Package (IEP). This can be done at any time and is extremely convenient when the clients’ needs change.
The model numbers are the exterior wall dimensions in inches. For example a MDL 4848 is 48″ x 48″ exterior wall to exterior wall (4′ x 4′). The acoustical foam provided attaches to the interior with Velcro in order for clients to have the ability to customize the interior to suit their needs. Each sheet of acoustical foam is 2′ x 4′ and 2″ thick, so if attached to opposing walls the interior space of the WhisperRoom™ would decrease by 4″ in each dimension. For example, the MDL 4848 is 4′ x 4′ exterior dimensions, but the interior (with foam on opposing walls) would be 3.5′ x 3.5. The exterior height for Standard models is 6’11” and for Enhanced models it is 7’1″. Interior height is 6’8″ for both Standard and Enhanced.The Enhanced models have two layers of barrier (3/4″ MDF) and the secondary set of walls is installed on the interior, so the interior space will decrease by 6.5″ or 10.5″ with the foam attached to opposing walls. This means that a MDL 4848 E would have approximately 3′ x 3′ of interior space.
The WhisperRoom™ is not soundproof, however it will provide significant sound isolation. For an enclosure to be soundproof it would require the use of massive, very heavy materials and elaborate architectural techniques to prevent air-borne and structure-borne sound leakage. The words PORTABLE and MODULAR insinuate that an enclosure can, with relative ease, be assembled/disassembled and relocated. In a nut shell, an enclosure cannot be both PORTABLE/MODULAR and SOUNDPROOF!
Every WhisperRoom™ component, including the door, is constructed of 3/4″ Medium Density Fiberboard (MDF) and completely wrapped with a durable 1/8″ thick, cloth type material for a total thickness of 1″/component. Standard isolation units consist of one layer of the MDF barrier, while Enhanced isolation units have two layers. You can upgrade from a Standard to an Enhanced at any time.

Every WhisperRoom™ includes enough Auralex® acoustical foam to cover approximately 30% of the interior wall surface. The acoustical foam, a basic WhisperRoom™ vocal booth feature attaches to the WhisperRoom™ wall with non-permanent, Velcro®, fasteners. This allows the interior acoustics of each unit to be tailored to accommodate specific client needs. No foam, or small amounts of foam, usually results in a live (highly reflective) interior sound, while large amounts of foam results in a dead (non-reflective) interior sound. Additional foam is available if desired.

The thickness and weight / sqft of a component means nothing unless the seam between each component has a noise reduction capability comparable to that of the components themselves. Simply covering seams with thin strips of plastic or metal and a layer of acoustical foam will not prevent sound leakage!

WhisperRoom™ wall components are attached to one another with components referred to as Seam Seals. Seam Seals are constructed of the same 1″ thick, 3.25 lbs/sqft barrier. They overlap 3 inches onto each wall component and are bolted, top-to-bottom. In addition to a very tight seam, this system provides an extremely solid structure.

WhisperRoom™ ceiling and floor components attach to the wall system with hinged brackets. Stainless steel bolts and pre-installed threaded inserts are used to attach components to one another. Our WhisperRoom™ Assembly Video will show you exactly how easily and effortlessly the wall components attach and both Sound Booth Videos will demonstrate just how effective our vocal sound booths are in reducing sound.
