Open-plan offices can present significant acoustic challenges, particularly where hard floors, glass partitions, exposed ceilings and other reflective surfaces are incorporated into the design. While these materials create a modern and attractive working environment, they can also contribute to excessive noise levels, poor speech clarity and reduced concentration. Conversations travel across open spaces, telephone calls become difficult to follow, and meeting rooms may provide insufficient speech privacy. Effective acoustic treatment can address these issues, creating a quieter, more comfortable and productive workplace without compromising the office's appearance.

​

Why Do Offices Become Noisy?

​

Office noise is often caused by sound reflecting off hard surfaces such as glazing, plasterboard walls, concrete ceilings and hard flooring. These reflections create reverberation, where sound continues to circulate within the room, increasing background noise levels and making conversations more difficult to understand. Open-plan offices are particularly susceptible because large, uninterrupted spaces allow sound to travel between workstations with limited absorption.

​

Acoustic wall panels, ceiling baffles and suspended rafts help control these reflections by absorbing sound energy, reducing reverberation and improving the overall acoustic environment. This can make conversations clearer, reduce the build-up of background noise and create more comfortable conditions for employees.

It is important to distinguish between sound absorption and sound insulation. Acoustic panels are designed to improve sound quality within a space, whereas sound insulation measures are intended to reduce noise transmission between rooms or floors. Where the main concern is conversations being overheard in adjacent offices or noise travelling between floors, additional measures such as upgraded partitions, acoustic doors or floating floor systems may be required.

Acoustic Treatment Options for Offices

​

At Torann Acoustics, we supply and install a range of acoustic solutions for offices, meeting rooms, breakout areas and collaborative workspaces throughout London and the South East. Acoustic wall panels are available in timber, PET felt and fabric-wrapped finishes, allowing treatments to be selected based on both acoustic performance and interior design requirements.

​

Suspended acoustic ceiling baffles and rafts are particularly effective in open-plan offices and larger workspaces where wall space may be limited. These systems can provide substantial sound absorption while accommodating existing lighting, ventilation and exposed building services. They can also be incorporated as decorative ceiling features, offering a combination of acoustic performance and architectural design.

​

Where noise transmission between floors is the primary concern, floating floor systems and other sound insulation measures can help reduce the transfer of impact noise and, where appropriately designed, airborne sound. The most suitable solution will depend on the existing construction, the source of the noise and the level of acoustic improvement required.

​

Our Approach to Office Acoustic Treatment

​

Our approach begins with an acoustic survey to assess the existing conditions and identify the main sources of noise and reverberation. Where appropriate, we measure reverberation time (RT60) and assess the room's dimensions, finishes and layout to establish the type and quantity of acoustic treatment required.

Following the survey, we provide a detailed fixed-price quotation outlining the proposed acoustic materials, coverage, finishes and installation requirements. This ensures that the recommended solution is appropriate for the space and that the scope of works is clearly defined before installation begins.

​

We understand the importance of minimising disruption to an occupied office. Our installation team can schedule works around normal operating hours where required, including evenings or weekends by arrangement. Many smaller, single-room acoustic installations can be completed within a day, although the programme will depend on the size of the space, access arrangements and extent of the proposed works.

Frequently Asked Questions

​

Will acoustic panels stop neighbouring offices from hearing our meetings?

​

Acoustic wall panels and ceiling treatments primarily absorb sound within a room, reducing reverberation and improving speech clarity. They do not provide significant sound insulation against noise travelling through partitions, glazing or doors. Where speech privacy is a concern, additional measures such as upgraded partitions, acoustic doors, perimeter seals or improvements to existing glazing may be necessary. We can assess the existing construction and advise on the most appropriate solution.

​

How many acoustic panels does our office need?

​

The quantity of acoustic treatment required depends on several factors, including the size of the room, ceiling height, existing surface finishes and how the space is used. A meeting room, for example, may require a different level of treatment from an open-plan office or breakout area. We assess the existing acoustic conditions and, where appropriate, measure reverberation time to determine the recommended panel coverage and placement.

​

​

Can acoustic treatment be installed without disrupting the office?

​

Yes. We can arrange installation around your office's operating hours to minimise disruption to employees and daily activities. Smaller installations can often be completed within a single working day, while larger projects may require a phased programme or out-of-hours working. We will confirm the anticipated installation duration and access requirements before works commence.
