Specifying Sound Reducing Doors
- In designing and specifying with sound reducing (acoustic) doors, it is important to consider the average db rating rather than the maximum db rating.
- For example a 45db door will have an average of 45db of sound reduction on several frequencies. The maximum db rating of the same door is probably closer to 55db at 4000Hz.
- In real life conditions there will always be “flanking”, which is room-to-room sound transmission caused by vibration. It always depends on a particular situation but allow up to 3db.
- Obviously, the db rating of the wall/panel construction should always be at least that of the door for the overall acoustic solution to be effective.
