Acoustic doors for recording studio

One of the most important elements in terms of acoustic insulation in a recording studio is the ACOUSTIC DOOR. The correct sealing of the enclosure at the insulation level depends on it and is part of the elements that allow access to and exit from the enclosure.

We must bear in mind that Acústica Integral manufactures a wide range of acoustic doors, adapting their characteristics to the different needs of the studio that is being built.

The RS10 model is common in music recording studios where the acoustic insulation requirements for airborne noise are very demanding. Mounted as a single element or combined with other doors to compose the acoustic vestibule so necessary in this type of installations. It is a robust door, with 54dB acoustic insulation. It has a lower frame and pressure closure, and can be adapted to the needs of the work both in its size and in the accessories it may incorporate.

The next model that is very common in studio construction is the RS3. Like the RS10 model, its insulation level reaches a value of 51dB, being among the door models that exceed the 50dB range so sought after for this type of installations. It is used for installations similar to the previous model when the airborne noise insulation requirements allow a greater margin. They are usually mounted as a single door or combined in a double format. They are also very suitable for the construction of acoustic halls. They have a lower frame and pressure closure and can incorporate the necessary accessories depending on the needs of the work.

Within the range of doors with a lower frame, there is a model with more limited acoustic insulation, which is the RS5 acoustic door. They are doors that achieve an acoustic insulation value for airborne noise of 46dB. They are used in studies with less restrictive isolation requirements. It has a pressure closure and can be adapted to the needs of the work in terms of shape and the range of accessories that may be needed.

Complementing these models are doors without a lower frame of the RS4 type, which allow us to achieve insulation values of 42dB but give us the advantage of adequate access for the disabled, or requirements for the movement of goods.

Where should the acoustic door be installed in a recording studio?

We must keep in mind that most recording studios are built following the "box in box" technique so that we have an external enclosure that is rigidly attached to the structure of the building that contains it; and an interior enclosure that is independent of the building structure and is constructed with floating elements. The acoustic door must be part of the floating box, so that when it is exposed to studio noise it does not transfer the vibration of its movement to the non-floating outer box. By definition, the door should always be mounted in the room where the greatest noise is produced, normally being the floating part in the case of recording studios.

Ideally, when we have an acoustic vestibule, an acoustic door will be installed in the interior enclosure and the second acoustic door in the exterior (floating) enclosure. This would be the optimal situation to achieve very high degrees of insulation.

If, in addition to installing a double door, the difference in weight between both (RS10 vs RS3) is taken into account, we will improve the insulation response thanks to the fact that the resonance frequencies of each model are different, and we will improve the acoustic response of the set at the level of isolation.

The acoustic door is an essential element to guarantee the mixed insulation of the wall where it is installed. It is essential to properly choose the degree of acoustic insulation of the door, and the quality of its manufacturing will be fundamental in the final results. The acoustic doors of Acústica Integral are in continuous development and improvement, controlling their acoustic characteristics through laboratory tests that guarantee their reliability in terms of the final results of an acoustic insulation work for study or other applications.

It is also important to highlight that the assembly experience of the installers will be of vital importance for this type of doors, since they are difficult to manipulate and adjust, taking into account that small assembly errors can ruin the final result of the installation that be carried out. We recommend that the assembly of this type of doors be carried out by specialized personnel, since they will be careful in the location, reception, alignment, leveling and finishing of the assembly so that the possible insulation losses associated with the assembly are negligible in the result.
