Ceiling Soundproofing

Sound Reduction Solutions – Noise Bleed Through a Ceiling

The average room is not equipped to protect against noise traveling freely between its ceiling and the floor of the room above. The common contact points connecting the ceiling of one room to the floor of the upper adjoining room serve as mediums through which sound vibrations naturally travel. Sound transmission describes the tendency of sound waves to travel through molecular structures, and is the behavior that must be counteracted in implementing a ceiling soundproofing treatment.

Since sound vibrations can travel through any molecular medium, including air, wood, drywall and metal, ceiling soundproofing treatments must target both air borne and structure borne noise. Noise bleed through a ceiling can be alleviated by the implementation of a treatment that blocks air borne sound waves and forces the collapse of structure borne sound waves, thus preventing noise from traveling through the common surface to become audible in the adjoining room.

Effectively controlling air borne sound transmission involves adding density to the ceiling structure, while structure borne vibrations can be alleviated by establishing a disconnection that forces sound waves to collapse rather than allowing them to transmit through the structure. Adding density to a ceiling is as simple as applying a specialized sound barrier membrane such as dB-Bloc over the surface of the ceiling, taking care to ensure that the entire surface is covered by the material. This heavy vinyl treatment can be affixed directly to a finished ceiling surface, or to exposed ceiling joists in an unfinished ceiling. While adding density serves to block air borne noise, establishing a disconnected ceiling surface is necessary to break down structure borne vibrations that would otherwise escape into adjoining rooms. A set of furring strips attached perpendicular to ceiling joists provides the foundation for a new layer of drywall, which is affixed parallel to the original ceiling surface. The disconnection created by the addition of this second ceiling surface serves to prevent the transmission of sound waves by eliminating the common contact points that would otherwise allow sound to travel directly into the adjoining room.

Necessary ceiling openings which accommodate light fixtures, ceiling fans, speakers and vents present a unique soundproofing challenge. Even with density and disconnection effectively applied to a ceiling, sound waves will naturally travel through such openings if they are left untreated. Specialized sound barrier treatments designed for positioning atop such ceiling openings are available to enhance the effectiveness of a ceiling soundproofing treatment. Because of the specialized nature of soundproofing projects, it is advised to consult with a reputable soundproofing supplier prior to attempting to implement any sound reduction treatment to ensure that all variables of your application are considered.

Super Wedge Acoustic Wall Tile 5" x 12" x 12" (UL 94) Each Sale Price: $11.76   Eligible for free shipping! Availability: Usually ships in 1-2 business days See Reviews For This Product Description Our Super Wedge acoustic wall tiles were designed to help control low frequency response problems within a room. Virtually all rooms have 90° corners where two walls come together and meet a flat ceiling. This corner, commonly referred as a "trihedral corner", can boost bass frequencies as much as 9 dB! By placing Super Wedge tiles in the corners (in an alternating pattern) from floor to ceiling, these low frequency anomalies can be controlled. Note: We recommend you start with Super Wedges in each corner. If the problem persists, you can add more wedges horizontally from the corner along the wall/ceiling juncture. The Super Wedge is made of open cell polyester foam that's flame retardant in accordance with UL 94 HF-1 flammability testing. The design is very pleasing to the eye while offering outstanding low frequency sound absorption qualities. Practical 12" x 12" tile size makes installation a snap. The perfect solution for recording studios, auditoriums, home theaters, anechoic chambers, radio stations, and more. Tiles easily installed with any foam spray adhesive, we recommend 3M Hi-Strength 90. Tile size is 12" x 12" x 5". Sold individually. Charcoal gray color.
