The entertainment industry operates at the sharp end of acoustic performance requirements. Recording studios, post-production dubbing stages, film scoring rooms, broadcast facilities, and streaming platform production spaces all demand acoustic environments in which the relationship between what is produced and what is heard is controlled with a precision most other building types never approach. The wrong acoustic treatment in a critical listening environment does not just affect comfort. It affects the quality of the final product and the efficiency of every session held in the space.
Acoustic plaster has become an increasingly significant specification choice across these environments over the past decade. Its combination of Class A sound absorption performance and a seamless, architecturally invisible finish makes it uniquely suited to spaces where acoustic treatment must perform without compromising either the room’s visual quality or the integrity of the monitoring environment. This guide covers how acoustic plaster performs across the key environment types within the entertainment industry, what specifiers and studio designers need to know before including it in a brief, and where it sits alongside other acoustic treatment options.
How Acoustic Plaster Works
Acoustic plaster is a seamless surface treatment applied in multiple layers to walls and ceilings over a mineral wool panel substrate. The mineral wool core is adhered to the structural surface, and the plaster finish is hand-applied over it to create a smooth, continuous surface that is visually identical to standard plaster. The key difference is acoustic: the plaster finish is microporous, allowing sound waves to pass through into the mineral wool core behind it, where the energy is absorbed and converted to heat rather than reflected back into the room.
This dual-mechanism absorption allows well-specified acoustic plaster systems to achieve Noise Reduction Coefficient ratings up to 1.00 across the audible frequency range. At mid- and high-frequencies, sound energy passes through the microporous surface finish and dissipates within the mineral fibre panel. At low frequencies, the panel surface acts as a diaphragm, vibrating in response to bass energy and converting that vibration into heat. The result is broadband absorption from a surface that gives no visual indication of its acoustic function.
Fabritech installs Baswa Acoustic systems for entertainment industry projects across the UK. Baswa Phon is available in system depths from 30mm to 70mm, with deeper systems delivering higher absorption coefficients and greater low-frequency performance, which is critical in environments where bass management is part of the acoustic brief. Full details of our acoustic plaster systems and installations across London are available on the Fabritech website.
Recording Studios
The acoustic requirements of a professional recording studio are among the most precisely defined of any building type. Control rooms, live rooms, vocal booths, and isolation rooms each have distinct and carefully calculated acoustic targets, typically expressed as reverberation time curves across the frequency spectrum, and the acoustic finish of every surface contributes to whether those targets are met.
In a control room, the primary function of acoustic treatment is to create a neutral monitoring environment. Engineers and producers need to hear the recording as accurately as possible, without the room adding colouration, frequency build-up, or reflections that could mislead their mix decisions. Acoustic plaster applied to the ceiling and upper wall sections of a control room absorbs early reflections from the mixing position and contributes to a shorter, more controlled reverberation time across the critical speech and music frequency range.
The seamless finish of acoustic plaster is particularly valuable in control rooms where the space’s visual language is carefully considered. Exposed foam, visible panel edges, or modular tile systems interrupt the clean architectural intent of a well-designed room. Acoustic plaster becomes part of the architecture rather than something applied to it, allowing designers to maintain the space’s visual quality without making any acoustic concessions.
In live rooms, where performers record, the acoustic requirements are different. Some degree of controlled reverb and natural room character is desirable, and the treatment typically combines absorptive and diffusive surfaces. Acoustic plaster on the ceiling or specific wall areas can provide absorptive coverage in a format that works with the overall acoustic design rather than dominating it.
Fabritech has completed acoustic plaster installations at Abbey Road Studios, one of the most acoustically demanding and historically significant recording environments in the world. This level of project experience gives our team a direct understanding of the precision that professional studio environments require and the coordination demands of working within live, programme-critical facilities.
Post-Production: Dubbing Stages and Mix Rooms
The post-production sector presents a different but equally demanding set of acoustic requirements. Dubbing stages, where the final mix of a film’s dialogue, music, and sound effects is assembled and balanced, are among the most technically exacting acoustic environments in any building type. A dubbing stage for theatrical film mixing must meet specific acoustic criteria set by the delivery format. Dolby Atmos, IMAX, and DTS:X each define acoustic standards that the room must conform to before it can be certified for use.
The key acoustic requirement in a dubbing stage is consistency. The room must behave predictably across the full frequency range so that a mix made in it will translate accurately to cinemas and home playback systems worldwide. This requires precise control of reverberation time, low early-reflection energy, and controlled decay across the low-, mid-, and high-frequency bands.
Acoustic plaster is specified in dubbing stages and mix rooms because it delivers the required absorption across a broad frequency spectrum while remaining unobtrusive to the room’s technical infrastructure. Speaker arrays in a Dolby Atmos mix room may be positioned across the entire ceiling and wall surface area. Acoustic plaster can be applied consistently across these surfaces, with speaker positions, cable conduit, and service penetrations integrated into the system during installation, maintaining the room’s seamless finish while accommodating the technical demands of a full-format mixing environment.
In the UK, Abbey Road Studios’ Mix Stage handles the final dub for major theatrical releases including Tar, Wonka, and Top Gun: Maverick. Post-production facilities of this calibre require acoustic treatment that meets the standards of the monitoring systems and technical infrastructure around them.
Film Scoring Stages
Film scoring stages are large orchestral recording rooms designed to capture the sound of a live ensemble for synchronisation with picture. They require an acoustic environment that sounds good to the performers, captures well to the microphone, and provides the room character that contributes to the distinctive sound of a scored film soundtrack.
The acoustic treatment of a scoring stage must balance natural reverb with clarity. Too much absorption and the room sounds dead, reducing the natural character of the ensemble and requiring significant artificial reverb to compensate in the mix. Too little and the room becomes difficult to control, with excessive decay that muddles the detail of complex orchestral writing.
Acoustic plaster applied to selected ceiling and wall surfaces in a scoring stage provides a consistent, controllable layer of absorption that can be specified in combination with diffusive surfaces and variable acoustic panels to achieve the target balance. The system depth, and therefore the absorption coefficient, can be varied across different areas of the room to tune the acoustic response.
For heritage-scoring venues, of which London has several, including the famous Studio One at Abbey Road, acoustic plaster is particularly valuable because it can be applied to curved and irregular surfaces including domed ceilings and vaulted geometry without visible seams or surface breaks. This makes it one of the few acoustic treatment options compatible with the architectural character of these spaces.
Broadcast Studios and Radio Facilities
Broadcast studios for television and radio have acoustic requirements that are driven primarily by speech intelligibility and microphone performance. A news studio, chat show set, or radio broadcast room needs to be acoustically quiet enough for clean microphone pickup, without room noise or reverberation that would affect the clarity of the broadcast signal.
The acoustic challenge in broadcast environments is compounded by the space’s visual requirements. A television studio must look good on camera, which means visible foam panels, ceiling baffles, or modular acoustic tiles are typically not viable. Acoustic plaster provides a solution that achieves the required absorption while maintaining the clean, production-ready visual quality that broadcast studios demand.
In radio broadcast facilities, the acoustic requirements are even more stringent in some respects. A speech-only broadcast room needs very low reverberation times, typically well below 0.3 seconds, to ensure that the spoken word is captured cleanly without room-induced colouration. Acoustic plaster applied across ceiling and wall surfaces, combined with appropriate carpet and furnishing absorption, can achieve these targets within a compact room footprint.
Streaming Platform Production Spaces
The past decade has seen a significant expansion in the number of dedicated production facilities commissioned by major streaming platforms. Netflix, Apple, Disney, and Spotify have all invested in bespoke production and post-production spaces across the UK. These facilities combine the acoustic requirements of traditional broadcast and recording environments with an emphasis on premium interior design and brand-quality aesthetics.
Fabritech has completed installations of acoustic plaster and fabric wall system in facilities for Netflix, Apple, Disney, and Spotify. In these environments, the acoustic treatment is specified to meet rigorous performance standards while contributing to a finished space that reflects the commissioning organisation’s quality and brand values. Acoustic plaster’s ability to deliver Class A performance within an architecturally invisible finish makes it a natural specification choice for environments where acoustic performance and visual quality carry equal weight.
Acoustic Plaster Versus Fabric Wall Systems in Entertainment Environments
Acoustic plaster and stretched-fabric wall systems are often evaluated together when specifying acoustic treatment for entertainment-industry spaces. Both can achieve similar levels of broadband absorption and produce a seamless finish with no visible panel edges or fixings. The choice between them typically comes down to the room’s specific requirements and the design’s aesthetic intent.
Acoustic plaster produces a surface that reads as standard plaster, smooth, monolithic, and entirely invisible as an acoustic treatment. It integrates with lighting fixtures, speaker locations, and service penetrations while maintaining the continuous ceiling and wall plane. It is the appropriate choice where the room design requires an absolutely clean, undifferentiated surface and where the acoustic treatment must be entirely subordinated to the architecture.
Fabric wall systems offer greater flexibility in finish appearance, with acoustic fabrics available in a wide range of colours, textures, and materials. They are particularly suited to environments where the fabric face contributes to the character of the room, such as home cinema installations, high-end residential studios, and commercial spaces where the acoustic treatment is intended as a design element rather than an invisible one.
In many entertainment industry projects, both systems are specified side by side. Acoustic plaster may cover the ceiling and primary wall areas, while fabric wall systems are used in specific areas where diffusion, speaker concealment, or a different surface quality is required. Fabritech installs both systems and can advise on the appropriate specification for each area of a complex acoustic brief. We also install fabric ceiling systems as part of complete acoustic fit-outs across entertainment and commercial environments.
Specification Considerations for Entertainment Industry Projects
For architects, acoustic consultants, and studio designers specifying acoustic plaster for entertainment-industry environments, several practical points should be confirmed at the design stage.
System depth determines low-frequency performance. A 30mm system provides excellent mid- and high-frequency absorption but a limited low-frequency contribution. A 70mm system extends absorption significantly into the low frequency range, which is relevant in mix rooms and control rooms where bass management is part of the acoustic design. System depth selection should be informed by the acoustic consultant’s target absorption curves for each room.
Service coordination is essential and must be resolved before installation begins. Speaker arrays, lighting positions, sprinkler heads, HVAC diffusers, and projection equipment must be installed and signed off before the acoustic plaster finish is applied. Getting this sequencing wrong is the most common cause of programme overruns in acoustic plaster projects. Fabritech works closely with main contractors, AV integrators, and acoustic consultants to coordinate the installation sequence from the earliest stages of the project programme.
Fire performance documentation must be confirmed for all entertainment industry environments. Acoustic plaster systems used in UK entertainment facilities must comply with UK building regulations. All Baswa Acoustic systems installed by Fabritech carry the appropriate fire classification certification, and full documentation is available for inclusion in the project’s fire strategy and building control submission.
Mock-up and sample approval are strongly recommended for any entertainment-industry acoustic plaster project. Fabritech supports mock-up panels and sample bays as part of the specification process, allowing clients to assess finish quality and colour match before full-scale installation.
