Designing Auditorium Acoustics for Speech, Music, or Both
An auditorium built for music will swallow a spoken-word production, and one built for speech will leave a live band sounding flat and lifeless. The reverberation time that flatters one use actively works against the other. Get the design wrong and no amount of amplification fixes it, the room itself is fighting the performance happening inside it.
Designed for the room's actual use, not a generic target
Speech intelligibility benefits from a shorter, more controlled reverberation time, clarity matters more than richness when the goal is understanding spoken word. Live music, particularly orchestral or acoustic performance, often benefits from a longer reverberation time, the room's natural decay is part of what makes the sound feel full rather than dry. These aren't compatible targets, and specifying one room to serve both uses well requires a genuinely different design decision, not a single compromise setting.
Treatment that becomes part of the architecture
Ceiling rafts and sculptural wall panels are specified to work as a visible design feature rather than a bolt-on fix, becoming part of the room's architecture rather than sitting apart from it as obviously retrofitted equipment. In a performance space, where the room itself is part of the audience's experience, this matters as much as the acoustic performance itself.
Bespoke engineering for raked and curved geometry
Most auditoriums are built with raked seating, curved walls, or other non-standard geometry specifically designed for sightlines and acoustics together. Custom acoustic engineering is standard practice for this kind of space, rather than adapting a generic flat-room panel layout to a room it was never designed for.
Coordinated with AV and stage systems from the design stage
Treatment is specified alongside sound reinforcement and stage equipment, coordinated from the design stage rather than fitted around existing systems afterwards, avoiding conflicts between acoustic treatment and speaker placement, rigging, or sightlines that only surface once both are already installed separately.
Common questions
Can treatment work for both speech and live music? It can, but the design differs meaningfully, we specify reverberation time based on how the room will actually be used, not a single blended target.
Can you work with a raked or curved auditorium shape? Yes, custom acoustic engineering is standard for auditorium geometry, rather than a generic flat-room approach.
Do you test the finished acoustics? Optionally. We can measure the room against its target reverberation time once treatment is installed, confirming the result rather than assuming it.
Designing for your actual programme
See our guide to reverberation time and RT60, our auditorium and theatre acoustics page, or book a free survey to design around what your space is actually used for.

From first survey to final finish
One team handles all seven stages, the same way on every project, so you always know what happens next.
A surveyor visits the site, or works from your drawings and photos when a visit isn't practical. Either way, the room, its surfaces and how it is used are recorded before any advice is given.
Reverberation, ambient noise and noise transfer are read against what the space is used for. The findings arrive as a written report with recommendations, yours to keep with no obligation to proceed.
Treatment is modelled against a reverberation target, then drawn up with panel positions, fixings and finishes. Nothing moves forward until you have approved the design.
Every quotation comes with the specification behind it, listing products by type, quantity and finish with costs set out line by line. What is quoted is what the design calls for.
Panels, baffles, ceilings and screens come from our Acoustic Solutions range and are supplied to the approved specification. What arrives on site matches what was designed.
Our own engineers fit to the approved drawings, checking positions and fixings as they go. One team supplies and installs, so nothing is handed between contractors.
Optional: after fit-out the space can be measured again and compared with the original survey, so the improvement is measured rather than assumed. Results are reported against the relevant standards and the written record goes into your building file.
