DSA Acoustic Sealing Systems for Door Assemblies


Whenever the need for QUIET is essential, the effective acoustic sealing around the perimeter of a door or window assembly is vital to prevent the passage of sound from one side to the other.

The main purpose of any door is to control physical access and so that the door can open and close effectively, there must be gaps around the door perimeter. Most of what we hear as sound travels through the air and left unsealed, these gaps will allow sound to pass through and therefore sealing these gaps is critical in reducing the amount of sound entering or leaving a room.

Door Seals of Australia have designed and developed a range of effective seal system solutions to specifically address acoustic issues for all four sides of the door that will create a physical barrier to ensure effective acoustic separation is achieved from unwanted sound. These seals fill the gaps and work with the door assembly to improve its performance when closed, while adding minimal resistance to the opening and closing operation of the door.

Our seals are being continually chosen for buildings including: Residential Buildings and Apartments, Hotels, Casinos and Gaming venues, Exhibition and Convention Centres, Office Buildings, Banks, Shopping Centres, Restaurants, Hotels, Places of Worship, Auditoriums, Entertainment Centres, Theatres, Cinemas, Concert Halls, Universities and Schools, Broadcasting and Film Studios, Data Centres, Call Centres, Hospitals and Medical facilities, Prisons and Law Courts, Military sites, Manufacturing and Mining sites.

Understanding the Relative Loudness of Sound & Unwanted Noise


A dB(a) is a unit of measurement that indicates the weighted sound pressure level of the relative loudness of sounds in air as perceived by the human ear. Noise is unwanted sound judged to be unpleasant, loud or disruptive to hearing and can be associated with negative health and workplace outcomes, depending on the duration and level of exposure.
