Acoustic Metal Doors

In the age of open floor plans and chiming cell phones, silence is golden. That may explain the growing demand by architects and building owners for sound resistant doors.

Acoustic doors are engineered to prevent a specific amount of sound from passing through a door.

Interior and Exterior Acoustic doors

A soundproof room is only as good as its components. If the door does not meet the same acoustical requirements as the rest of the room, then sound will easily pass through it to adjoining spaces. When fitted with the right door and sealing systems, noise will be contained and controlled.

Soundproof interior and exterior acoustic doors are an ideal cost effective solution for recording studios, hotels, music rooms, conference rooms, or any space that needs to be soundproof. Our pre-hung acoustic doors feature multilayer construction in a variety of wooden finish options suitable for indoor applications or metal for exterior use. If the door itself is not a problem, it could be that sound is leaking through the space between to door and the jamb.

Acoustic Metal Doors

Usages

Soundproof and acoustical doors and windows, in wood or metal, are used in premiere live performance venues and industrial applications where sound containment is of primary concern.
Radio & TV Broadcast Studios
Recording Studios
School Music Facilities
Movie Theaters
Museums
Sensitive Compartmented Information Facilities (SCIF) etc.

Availability

Acoustical doors are available in flush designs or with vision lights, as singles or pairs, including single or bi-parting horizontal sliding doors, and as manual or power operated assemblies.

Sound proof

Sound is defined as pressure variations (oscillations) in air, water, or other mediums that can be detected by the human ear and the number of vibrations per second is referred to as the frequency of sound and is measured in Hertz or Hz. Human hearing ranges from approximately 20 Hz to 20,000 Hz, with the frequencies of speech ranging from 20 Hz to 8,000 Hz. Sound level meters are designed with a series of filters over the audible frequency range to simulate the varying sensitivity of the human ear. This is referred to as A-Weighting and measured sound power levels are designated as dB.

Installation

Vision lites can reduce the overall effectiveness of acoustic doors but are often necessary for many reasons. Glass is rigid and therefore does not exhibit very acceptable sound reduction properties. However, the use of double paned laminated glass of different thicknesses tends to increase the effectiveness and the combination of each pane vibrating at different frequencies coupled with gasket isolation and airspace between works quite well.

It is imperative that acoustic door assemblies are installed with precision. Noise, like water, seeks the point of least resistance and therefore frames must be installed plumb, square and true, doors must be adjusted for proper clearance, thresholds must be level and all perimeter seals, door bottoms and astragals must be properly adjusted.

Acoustical door rating scale

Acoustical door and window products are rated on a Sound Transmission Class scale. A STC 55 door is capable of reducing the sound of a jet engine (130 DBA) to that of a typical office (60 DBA).
