Basics of acoustic doors


Noisy situations are unavoidable when you (or your neighbor) want to live your life to its fullest. The exact opposite could also happen. Maybe you have a newborn in your home right now that needs a good amount of sound sleep. Or maybe your kids have formed a band and the decibel level reach heights that your house hasn’t witnessed before. So, there’s a fear of your neighbors complaining. Important and complex jobs demand a noise-free environment so that people can concentrate better for maximum output.

This article aims to discuss the needs and applications of an acoustic door in Melbourne.

What are acoustic doors?

As the name suggests, acoustic doors are designed to block noise and vibrations. The body of these doors is made with insulating components, all thanks to insulation engineering. Sound reflects when they hit an acoustic door. This is how they insulate the sound within a room.

What materials are used in acoustic doors?

Acoustic doors must be made of materials that either reflect or absorb sound vibrations. The materials usually used to make acoustic doors are:

  • Aluminium
  • Steel
  • PVC
  • Timber

Thickness and soundproofing capabilities 

The greater and denser the mass of the door, the better sound-insulating capabilities it has. There is also another smart way to provide heavy-duty insulation. A good quality single door or a pair of two acoustic doors is used to achieve high-quality insulation. Heavy-duty insulation is needed in places like movie theaters and studios. To achieve further sound insulation, dense cores are sandwiched together and insulating foam is used.

How are these doors produced?

Acoustic doors in Melbourne are created from a solid core material that acts as a good sound insulator. Insulating foams and reinforced cores are used to achieve sound insulation. Acoustic seals are used in them that create an airtight seal that also prevents sound transmission.

Acoustic doors come in different insulation levels such as 32 dB, 34 dB, 38 dB, 42 dB and 44 dB. Depending on the insulation requirements, you have to make the choice.

Types of acoustic seals

  • Batwing seals: Batwing seals are medium-duty seals that block sound and smoke. The curved fins in these seals minimize the opening and closing resistance of the door. The fins are made of flexible material that restores to its original shape which makes them super durable.
  • Drop down seals: Dropdown seals are fitted at the bottom of the door that drops down automatically when the door is closed. This can also prevent the passage of fire and smoke. So, the drop-down has the potential to prevent the fire from spreading into the room.

Benefits of acoustic doors

Health and well-being:

Monotonous loud and unpleasant noise can take your mind off of work. Although it is difficult to realize, the prolonged presence of loud sound can cause severe stress. Eliminating unwanted noise can make you feel substantially calmer, improve concentration and give you a good night’s sleep. A good acoustic door can also prevent dust or smoke from entering your room. A calm and clean room is one of the best ways to achieve good health.


Acoustic doors not only block outdoor noise but also hold the sound produced inside a room. There are a lot of such places that need absolute privacy. Medical facilities are one of them. Hospital is a place for the sick. Hence a quiet environment is needed for healing.

Important meetings and business calls are mostly confidential. So, a soundproof space is needed to maintain confidentiality.


Loud noise is annoying but sounds over 85 dB can potentially cause hearing loss. Hearing loss is hard to realize until you have lost a significant amount of hearing capabilities. If you live near a factory that produces ceaseless loud sounds, acoustic doors are a great option to make your living space serene and peaceful. There are specific decibel ratings that provide different levels of sound insulation. Inspect your environment in Melbourne to detect the noise level and choose the one that suits your needs.
