Acoustic doors and their importance in specific environments

Today, people are too particular about their personal isolation, so the need for noise cancelling installations has increased over the years. Acoustic doors are one of the important interior solutions for preventing noise interference.

There are specific environments such as premier live performance venues and other commercial spaces, where noise and sound control is of primary concern. Therefore, proper and super quality noise-controlling doors are required in such locations for acoustic absorption.

However, the building designers must consider certain factors before acoustic door installation. The major factors of concern are the structure of the door set, location, test evidence and the reason why such acoustic installation is required.

Environments where acoustic doors are essential:

  • Theaters
  • Auditoriums
  • Libraries
  • Band practice rooms
  • Machining room entrances
  • Sound sensitive commercial spaces
  • Private government settings, and other rooms

Here are some essential points about acoustic doors and their importance in the aforementioned environments:

  1. Noise cancellation: Basically, the sound is reflected into the localized environment, as well as some of it being absorbed when struck onto the surface. But the reflected sound can go out of the specific room (for example, a music room) and may disturb the neighbouring spaces. So, acoustic doors could be one way to prevent noise interference in other rooms of a particular building or neighbouring buildings.
  1. Measure time for reverberation: Before installation of the acoustic doors, an acoustic engineer firstly measures the time that it takes for sound to reverberate in a room. This way the best type of acoustic door can be selected for specific environments such as hospitals, music rooms, auditoriums.
  1. Tuning of space: Another important thing that’s considered before installation is that a particular room or space needs to be “tuned” to work out the reverberation time of the specific area. According to that, a suitable type of door can be selected. Moreover, reverberation times can also be adjusted by other sound absorbers like interior furnishings.
  1. Types of acoustic doors: The types of materials used in the acoustic door varies according to the building and use of the room. This is because some acoustic doors that may be suitable for small music rooms may not be effective in large auditoriums or cathedral halls where the sounds made by the orchestra need to reverberate in a particular way. Hence, it’s important to know that where the particular acoustic doors need to be installed for better sound absorption and reverberation.
