The doors in a building very much reflect its purpose. All public, commercial and industrial buildings require fire doors, but how about other special purpose doors? What other options are avaliable?
One element to consider is soundproofing. Acoustic doors are those that have implemented a sound insulation and sound absorption component into their build. The greater the mass of the insulation material per unit area of a door, the more soundproof it will be. A double-leaf partition – two sections separated by an air gap filled with a sound absorber – is an efficient and practical sound absorber.
But who requires acoustic doors? Let’s take a look.
Soundproofing and recording studios go hand-in-hand. Ensuring that ambient noise is constrained is fundamental to the construction of a studio. This is achieved by implementing acoustically treated barriers in recording spaces and control rooms.
Acoustic doors can be purchased to suit a range of frame types and sizes, depending on the needs of your recording studio. These include single or double swinging doors, single or double sliding doors, and even smoke or fire doors.
Theatres, Auditoriums, Concert Halls
Acoustic doors are a very important element of theatres, auditoriums, concert halls, and other large spaces where containing and controlling the diffusion of noise is key.
These spaces vary greatly, from homes theatres to commercial theatres, large concert halls, and schools and universities auditoriums, and thus other factors come into play when thinking about these acoustic doors, such as fire proofing.
Aside from theatres or auditorium, other commercial spaces that require acoustically treated doors include, office buildings, night clubs, bars and music venues, medical institutions like audiology facilities and even x-ray facilities, general corporate and office buildings, hotels and airports.
In Australia, commercial acoustic doors must meet certain ‘Rw’ sound resistant standards set out by the BCA and are tested and certified accordingly (see: ISO 140-3: 1995 – “acoustics – measurement of sound insulation of buildings and of building elements”).
Industrial facilities present very specific conditions when it comes to sound attenuation. Acoustic doors are built to an extremely high quality when it comes to both soundproofing and safety, suitable for many industrial applications, including noisy plants and equipment/machinery rooms, warehouse facilties, industrial workspaces and manufacturing buildings.
As mentioned, acoustic doors can double as fire doors and other protective doors. They can also be used in boundary walls, where both noise control and fire resistance may be required – very important in industrial facilities that house hazardous activity/materials.
