Acoustic Panels for Cafes

Because of the Lombard effect. Once background noise passes roughly 57 dB(A), people raise their voices by about half a decibel for every extra decibel in the room, which lifts the background further. Adding customers does not raise noise in a straight line, it compounds. This is why a cafe can be pleasant at 11am and exhausting at 1pm with no other change.

Enough Class A absorption to cover 50 to 60 percent of the ceiling area. For an 80 m² cafe that is roughly 40 to 48 m², or around 35 to 40 standard rafts. Smaller cafes scale down proportionally. The figure depends on the existing finishes, so a room with carpet and banquette seating already has a head start over one with polished concrete.

Not if they are specified as part of the scheme rather than added afterwards. Panels can be made to order in a wide range of fabric colours and cut to non-standard shapes, and ceiling rafts can be arranged to line through with lighting and joinery. Printed and colour-matched panels are common in cafe fit-outs, where the ceiling often ends up as a design feature.

In most cafes the ceiling does nearly all the work. Wall area is taken up by glazing, menu boards, counters and shelving, so there is rarely enough of it to hit a target on walls alone. Rafts and baffles above the seating area are the standard approach, with wall panels added in the upper zone above head height where space allows.

No, and it is worth being clear about the difference. Treatment removes reflected sound, not the sound people make. A treated cafe still sounds occupied and busy, it just stops the noise stacking on itself. The aim is a room that sounds full rather than one that sounds loud, which is why full absorption of every surface is never the specification.

Yes, with the right specification. Panels near preparation and serving areas need wipeable or cleanable facings, and fire performance has to suit the setting. Ceiling rafts sit well clear of food zones, which is one reason they suit cafes. Confirm the finish and fire class against the environment at specification stage rather than assuming a standard fabric will do.

A typical cafe is a one to two day install, and most schemes are done overnight or between trading days so the room is ready for opening. Panel systems are mechanically fixed or bonded, with no wet trades and minimal dust. Rafts need access equipment over the seating area, so those are normally fitted outside trading hours.

Yes, and it is measurable. Laptop customers stay longest and spend most per visit, and they leave when speech from surrounding tables becomes intelligible enough to be distracting. Absorption shortens the distance over which nearby conversation carries, which is the thing that makes a table workable rather than the overall volume.

No. Panels absorb sound inside the room. They do not block sound passing through the ceiling, party wall or shopfront. Noise breakout is a sound insulation problem, and the remedy is the construction rather than the finish. NOVA Acoustics carries out UKAS-accredited sound insulation testing and can identify the actual path, which matters if a licensing condition or a complaint is involved.

The published research puts a number on it. Above roughly 51 dB(A), willingness to stay drops by about 2.2 percentage points per additional decibel, and willingness to spend by about 1.7. Small cafes cross that threshold with fewer customers than large ones, because there is less absorption in the room to begin with, so the payback tends to be quicker rather than slower.
