An Overview of Sound Rated Doors
FSE’s sound rated doors are perfect if your building project requires soundproofing or noise control. Here is a handy overview of sound rated doors
The Basics of Sound Rated Doors
Sound rated doors help to insulate sound and protect employees, visitors and other members of the public against potential noise pollution in certain industries.
• Just like any other protective door, sound rated doors must meet ‘RW’ sound resistant standards that are set by the Building Code of Australia. Thy should be tested to make sure that they meet these stringent requirements (For further information, see: ISO 140-3: 1995 – “Acoustics – Measurement of sound insulation of buildings and of building elements”).
• Sound rated doors can also meet other safety requirements. For example, some acoustic doors are also fire rated doors, so they can meet a multipurpose protective function.
• Sound rated doors come in many different materials for different purposes, including galvanised steel, laminated steel and sheet metal.
• Sound rated doors can also be installed with decorative veneers or finishes to suit the interior design of your business.
How Do Sound Rated Doors Work?
Volume is a measure of vibrations through a medium, usually air. The stronger the vibrations, the higher the human ear perceives volume. Sound rated doors work by restricting the amount of vibrations that can pass through.
Most doors – and solid objects for that matter – work as a sound barrier in some way. Despite this, sound waves can still make it through unless further measures are taken. Sound rated doors use sound insulation, sound absorption and sound preventative seals to stop any vibrations from passing through, providing a complete acoustic seal.
Sound insulation is the process of placing a barrier to block sound – the greater the mass of insulation per unit area of a door, the more soundproof it will be. Dense materials like concrete can be good for blocking sound, however, it is impractical to mount within a door frame. A common solution is a double leaf partition, which uses two separate sections that hold an air gap between them.
Sound insulation materials can sometimes be reflective, especially denser materials, this is why sound absorption is just as crucial. Sound absorbing material is placed within the double leaf partition to stop the reflection of sound, the higher the materials absorption quality, the less it will reflect.
Sealing the gap around acoustic doors is also very important. A small crack in the door can be all it takes to enable sound vibrations to reflect or penetrate through the door, so a seal is vital. Acoustic doors work by reducing the amount of sound that passes through the door leaf, so by sealing the gap around the door with acoustic door seals, a complete sound isolation is achieved.
Which Industries Use Sound Rated Doors?
Acoustic sound rated doors are used in a variety of different industries, not all with direct relations to music or sound. Many commercial, industrial and public companies all require soundproof doors for noise pollution or even security purposes.
• Music studios and TV recording studios
• Music and concert venues
• Nightclubs and bars
• Theatres and cinemas
• Manufacturing plants and factories, particularly those that involve loud machinery
• Medical institutions, like audiology facilities and even x-ray facilities
• Public institutions like schools and university buildings
• General corporate and office buildings
• Police stations (interview rooms)
• Commercial spaces like hotels and offices
• Architectural design soundproofing
• Transport hub soundproofing
• Aquatic centre soundproofing
• Marine soundproofing
• Building and construction soundproofing
• Sports stadium soundproofing
• Plant room soundproofing
• Genset enclosure soundproofing
• Restaurant and cafe soundproofing
• Server cabinet soundproofing
Types of Acoustic Doors
Sound rated doors can be purchased to suit a range of needs, depending on your construction project.
Your acoustic doors can be designed as:
• Single or double swinging doors
• Single or double sliding doors
• Fire or smoke doors
• Heavy or lightweight doors
• Electronic, automatic or magnamatic doors
All door types can be built with the specifically required accessories and hardware, including frames, hinges, acoustic seals, handles and closing/locking mechanisms, as well as additional needs like viewing windows.
At FSE Special Purpose Doors in Sydney, we manufacture and install both general acoustic doors and soundproof doors, and acoustic fire doors for a range of building projects. Hopefully, our overview of Sound Rated Doors was helpful for you in choosing the right option for your project.
