Acoustic Doorsets (AC35, AC45, AC50)

 Acoustic Doorsets (AC35, AC45, AC50) We supply a range of doors designed to reduce the transference of noise from one area to another.

Acoustic doors are used in many applications to offer privacy or to reduce noise pollution from one area to another. More stringent legislation makes it a requirement to consider the effects of noise pollution on the local environment.

Our standard doors offer a low level of acoustic performance but for higher acoustic performance we custom manufacture doors tested to 45dB and 50dB.

Due to the high performance criteria of these doors they are of a heavy-duty design and are a more difficult doorset to install with tighter tolerances than our basic doors.

These doors have been tested as fully-installed door systems and should be installed by our trained engineers only. For example, a 5mm gap at the bottom of a door capable of reducing sound transmission by 45dB would result in an overall sound reduction of only 25dB. In other words, 250 times as much sound energy is transmitted underneath the door as through the door.

How is Acoustic Performance Measured?

The performance of the door is described as the “Sound Reduction Index” and is shown as a figure xx dB. It is a weighted average over a range of frequencies prescribed in the test standard: BS EN ISO 140-3: 1995.

Type Rw Performance Description
FD* 22 Minimal Speech clearly audible
FD-M* 25 Average Normal speech understood
AC35 ** 35 Good Loud speech audible but not intelligible
AC45 ** 45 Very Good Loud speech just detectable
AC50 ** 50 Excellent Loud speech barely audible

* Standard general purpose door
** Specific Acoustic Door
