A facilities manager’s guide to reverberation

What reverberation is, and why it matters in your space

Most noise complaints in commercial spaces have the same root cause, and it’s not what people expect. When people describe a space as noisy, echoey, tiring, or hard to concentrate in, they are usually experiencing the effects of reverberation, even if they rarely name it that way.

Reverberation is the behaviour of noise after it is produced. Every conversation, footstep, chair scrape, and keyboard click generates acoustic energy. In a space with hard, reflective surfaces, that energy doesn’t stop when the source does. It bounces off walls, ceilings, glass, and floors, slowly decaying as it continues to reflect around the room.

The technical measure of this behaviour is RT60: the time it takes for acoustic energy to reduce by 60 decibels. In a space with an RT60 of 1.5 seconds, a single spoken word is still audible more than a second after it was spoken. Layer in the next word, and the next, and you can imagine how speech becomes dense, difficult to separate, and exhausting to process.

That’s how reverberation can negatively affect your space.

Why modern commercial interiors are particularly vulnerable to reverberation

The design preferences that have dominated commercial interiors for the past two decades, think polished concrete, glass partition walls, exposed services ceilings, and large open-plan floor plans, are acoustically demanding environments.

These surfaces are excellent reflectors. Unlike carpeted floors, upholstered furnishings, and textured wall finishes, they contribute almost no absorption. The result is spaces that look clean, modern, and visually impressive but feel acoustically harsh and fatiguing once occupied.

This disconnect between visual design intent and acoustic experience is one of the most consistent complaints facilities managers encounter. The space looked perfect in the renders. The moment people moved in, the noise complaints began.

Where reverberation problems show up most

Facilities teams regularly encounter reverberation issues in boardrooms, meeting rooms, reception areas, open-plan office floors, and food-and-beverage spaces. Corridors and circulation areas are often underestimated as acoustic contributors, yet these transition spaces, with their hard surfaces, add to a building’s cumulative noise load in ways that compound over time.

Healthcare environments present particular challenges for facilities managers. Nurses’ stations, waiting areas, and consultation corridors generate significant noise that travels easily in hard-walled healthcare buildings. Acoustic privacy, to ensure private conversations are not inadvertently shared, adds a second dimension to the reverberation problem in these settings.

Education spaces, particularly open learning areas and multipurpose halls, sit at the sharp end of the problem. These spaces are used intensively, often at high noise levels, and frequently arrive without any acoustic treatment.

What to look for when planning your acoustic treatment

Addressing reverberation calls for understanding the specific acoustic characteristics of a space before specifying any product. Ceiling height, room volume, surface materials, occupancy levels, and how the space is used will all influence what type and quantity of absorption is needed.

And strategic placement of acoustic treatment matters enormously. Panels installed thoughtfully across wall surfaces and ceilings can improve RT60 significantly, even with relatively modest coverage. The goal is to interrupt the routes noise takes as it bounces back and forth across the longest dimensions of the room (known as the dominant reflection paths).

Both Calando acoustic panel and ECO Wall acoustic panel offer facilities teams a winning combination of genuine performance and design flexibility. Both can be specified in configurations and finishes that respect your space’s existing design, whether it’s a corporate boardroom, a school library, or a healthcare reception area.

Why you should plan to address reverberation early

Reverberation is far more cost-efficient to address during the refurbishment or design phase than it is after a space is occupied. Retrofitting acoustic treatment to an occupied workplace requires scheduling around business hours, may involve temporary disruption, and typically costs more per unit of improvement than acoustic planning at the outset.

The most forward-thinking facilities teams we work with have moved acoustic planning from the reactive complaints list to the proactive specification process. They ask acoustic questions during the design brief, include RT60 targets in the project scope, and measure performance on completion.
