Over one million Noise-Lock® acoustic doorsets have been installed in industrial and commercial buildings throughout the world. Our range of acoustic doors spans Rw50dB to Rw63dB and higher, in specialist configurations. Noise-Lock® modular soundproof doors in single or double doorset styles are combined with a multitude of installation and design details to deliver a world leading noise control solution.
The Noise-Lock® modular soundproof doorset system creates a product solution for noise control which is equally capable of application in a recording studio or a power plant. This is only possible through the exact tolerances yet robust design and manufacture features of the doorset. We create a high quality aesthetic with a premium appearance and durable performance which is appropriate to any project environment.
Noise-Lock® soundproof doors are suited to virtually any noise reduction situation where sound must be contained within or excluded from a room or building, some typical applications include:
The Geelong Arts Centre, established in 1981, is a key cultural hub for the Geelong and G21 region, welcoming over 180,000 visitors and 15,000 artists each year across its theatres, studios, and creative spaces.
As part of a major redevelopment, including new performance venues, an upgraded box office, and enhanced back-of-house and administration facilities, the project aimed to position the centre as “the jewel of Geelong’s cultural district.”
Working alongside Lendlease, IAC Acoustics was engaged to deliver a series of specialist acoustic solutions. The scope included seven large acoustic doors, a bespoke sliding doorset with glazed panels for the theatre, and a large external sliding door integrated into the theatre façade.
Each element was engineered to meet the performance demands of a busy, multi-use arts environment, while aligning with the architectural vision of the redevelopment.

The Sydney Swans, one of Australia’s oldest professional football clubs with origins dating back to 1873, required a high-performance acoustic solution for their new training and development centre.
Located within the historic Royal Hall of Industries at Moore Park, the project involved the installation of a soundproof doorset for an auditorium space. The brief called for a solution that would deliver exceptional acoustic control while integrating seamlessly with the building’s architectural character.
To meet these requirements, a Noise-Lock® D-50 double doorset was specified, offering an acoustic rating of Rw 50dB. The doorset was also equipped with integrated digital access control, ensuring secure and controlled entry to the space.
As with every project, detailed acoustic assessments were carried out across relevant frequency ranges to ensure the solution met the precise performance demands of the environment. In addition to performance, the doorset was customised with a polyester powder coat finish, allowing it to align with the overall design intent of the facility.
This project demonstrates how engineered acoustic solutions can successfully balance performance, security, and architectural sensitivity. Even within heritage settings and elite sports environments.

Not quite.
While weight helps, true soundproofing comes from a combination of material (like steel), internal design, and precision engineering. A heavy timber door alone won’t match high-performance acoustic ratings.
It’s what’s inside that counts.
High-performance acoustic doors use special internal layers and decoupled structures to stop vibration and block sound – especially low frequencies that easily pass through standard doors.
Yes – dramatically.
Even a small gap around a door can cause a major acoustic leak. That’s why advanced sealing systems (often double or triple seals) are critical to performance.
With smart engineering.
Special cam-lift hinges gently lower the door into place when closed, creating a tight, consistent seal without dragging on the floor – improving both performance and accessibility.
Much bigger than you’d think.
Because sound works on a logarithmic scale, a door rated at 50dB isn’t just a bit better than 35dB – it represents a huge reduction in sound energy.
No – different spaces need different solutions.
Studios focus on low frequencies, technical rooms on high frequencies, and testing facilities often require full-spectrum control.
IAC Acoustics Noise-Lock® acoustic doors are manufactured as an engineered system — factory assembled complete with a door leaf, frame, architrave, acoustic seals, cam-lift hinges and operational hardware or ironmongery. All doors are pre-hung for operational alignment, fit and finish before shipping.
Key design features for all Noise-Lock® soundproof doors include:
Noise-Lock® sound reduction doorsets have two standard frame arrangements which cover the large majority of in-field project design requirements. The traditional frame and architrave arrangement is our most popular design configuration. The main part of the frame return wraps around the wall face – once partially installed, a notched male architrave assembly is pushed in from the opposite side into the back of the frame.
The architrave is assembled and delivered as a single piece construction in all but the very largest of installations. The finished assembly completely encloses around the host wall as per the illustration:
It is not always possible to install an enclosed or wrap around frame and architrave style solution. If for example the soundproof door is within a corridor, or the architect’s design requires a flush face finish.
As an alternative, we offer an in-board or tunnel type frame arrangement. The frame returns are minimised which suits projects where either there isn’t a host wall to fully wrap around, or the wall finishes may be built up with some form of cladding or detail which creates a seamless architectural finish.
We have over many thousands of projects been able to develop customised design details to suit those more complex sound reduction installations. Our Door team and Engineers will be happy to review any requirements and advise if these are possible to manufacture while maintaining acoustic integrity.
Noise-Lock® Acoustic Doorsets are available in a very broad spectrum of Polyester Powder Coat paint finishes.
We prime and paint all door leaf and frame assemblies before final fit-up of the door hardware. The doorset is then checked for operational fit, alignment and performance. The quality of paint finish is guaranteed – all the hardware penetrations and fixing systems are laser cut pre-fabrication and fully integrated, meaning no risk to the final finish with manual fabrication processes.
We typically are able to powder coat to any standard RAL colour chart or BS colour chart selection using a wide variety of high quality powder manufacturers.
Digitally printed wraps have also been used at surface finishes on Noise-Lock® Acoustic Doorsets with great success, enabling unique images, patterns and colours to be architecturally and visually coordinated with the surrounding spaces and room environment.
Other specialist finishes previously supplied on IAC Acoustics acoustic doors include timber cladding, stone cladding, stainless steel, linishing, laminate and veneer. Please discuss any custom requirements with our Door Team today.
Noise-Lock® Acoustic Doorsets are available with a range of glazed screens or vision panels, we offer the following standard configurations;
These standard designs on single acoustic door leafs can be repeated either on one or two leafs in a double doorset. Depending on the access requirements and hardware specifications the vision panels options can provide a multitude of configurations to suit a clients project and safety requirements. On request we can provide custom solutions – please contact our Door Team for further consultation.
Our soundproof door vision panels are glazed laminated safety glass to match the specified acoustic door set performance, with no loss of integrity. The frame assemblies are manufactured from the same materials as the doorset, are acoustically decoupled and finished in polyester powder coat for a consistent high quality architectural aesthetic.
Noise-Lock® soundproof doors are designed primarily to function as high performance noise control models, and therefore are heavy by design – ranging from 44kg/m2 to 88kg m/2 across the five model range.
For this specific reason, the range of door furniture or hardware we provide as standard is selected based on;
The products and brands we approve have been through rigorous testing and compliance assessment in our own factory, alongside the in-house product certification the original manufacture will have undertaken.
The range we have developed over recent years provides options to satisfy the large majority of project design requirements. This includes options for electrical access control systems and even powered automatic operator systems. Further standard hardware options, plus many further hardware items can be found in our Acoustic Doors Hardware Catalogue.
Once approved the selected products are programmed into our production database which ensures that all necessary penetrations, mounting systems and fixing details are incorporated into the laser cutting material planning and assembly process. All soundproof door hardware is installed and tested for operational fit and finish in the factory before the door is shipped to the project site.
We have a number of standard hardware packs and configurations which cover the main requirements of most project installations. Typical example of a single fire door and a panic escape double door are indicated below:
Noise-Lock® acoustic doorsets have undergone laboratory testing in both IAC Acoustics R&D facilities and independent laboratories to ISO 10140-2:2010. This is further supported by installed site testing – IAC Acoustics is renowned for quality, durability and guarantees in-field performance.
Summary of our Noise-Lock® acoustic doorset sound reduction performance levels and octave band centre frequencies:
IAC Acoustics offers a range of acoustic fire door & doorset products to BS476-22:1987 with further testing in process to the EN 1634-1 standard. Fire Standards are complex with performance measurement for overall Integrity and Insulation characteristics. This is applied alongside varied scope for the practical Field of Application of single and double doorsets, with acceptable design configurations.
There are specific combinations on single or double doorsets which may require further clarification relative to doorset size, or for the inclusion of vision panels and specific ironmongery requests or combinations – therefore we always suggest you consult for exact project specification and clarification with our Door Team.
IAC Acoustics Noise-Lock® acoustic doorsets have undergone rigorous testing for assessment of CE Marking standards to BS EN 14351-1:2006. This is a compulsory standard on external doorsets. As of October 2019 this scope was expanded to incorporate fire rated doors under the EN 16034-1 harmonised standard.
The testing covers key performance areas which are also aligned closely with the required performance characteristics of an acoustic doorset – air permeability and water tightness are aligned with high quality acoustic sealing performance.
A summary of the mandatory characteristics and standards for BS EN 14351-1:2006:
| 1/1 Octave Band Ctr. Freq. (Hz) | ||||||||
|---|---|---|---|---|---|---|---|---|
| 125 | 250 | 500 | 1k | 2k | 4k | 8k | Average (seconds) | |
| Typical RT | 0.22 | 0.20 | 0.30 | 0.41 | 0.52 | 0.47 | - | 0.35 |
| Typical RT | 0.22 | 0.20 | 0.30 | 0.41 | 0.52 | 0.47 | - | 0.35 |
At the current time IAC Acoustics is updating its BS476 Part 22 fire rated testing and field assessments to the EN16034-1 standard. We will be publishing further content and information regarding this in the near future.
Until this process is complete, due to the changes in the October 2019 BS EN 14351-1:2006 standard, we cannot currently supply a CE marked external fire rated acoustic doorset.
We can continue to supply CE Marked external non fire rated acoustic doorsets and internal acoustic doorsets in either fire rated or standard designs.
