Acoustic Comfort
Managing sound in tile-lined Porto café rooms without silencing the room
Controlling chatter in narrow granite boxes
Hard surfaces dominate heritage interiors: stone floors, plaster ceilings, and glass storefronts reflect conversation back into the room. Without absorption, speech levels climb until every table competes with the next.
We target a mid-room reverberation time around 0.7 seconds — lively enough for café atmosphere, calm enough for unstrained conversation.
Ceiling baffles that look intentional
Suspended felt panels above banquette rows absorb high frequencies without the office-ceiling aesthetic. In exposed-beam Ribeira units we hang baffles between joists, painted to match timber so they read as architectural detail.
Spacing panels at one-third room width breaks up standing waves common in rooms longer than six metres.
Balancing hard counters with soft seating
Polished stone counters and metal machine surfaces reflect grinder noise toward dining areas. Upholstered banquettes and curtain panels on side walls restore balance by adding absorption at ear height where guests actually sit.
Rug layers over tile in seating zones reduce chair scrape without hiding the floor character owners paid to restore.
Separating open kitchen energy from dining calm
Pass-through openings between prep and dining areas carry clatter along with aroma. A partial-height glass screen with an acoustic laminate core blocks direct sound paths while keeping visual connection for open-kitchen concepts.
Door sweeps and gasket seals on cold-room entries prevent compressor hum from becoming the room's background tone.
Background sound zones as design intent
We map speaker placement so music volume stays even across tables — not loud near the counter and faint by the window. Two small ceiling speakers often outperform one large unit in L-shaped Miragaia layouts.
