Office noise: what it costs your business and how to bring back quiet

The open-plan office was invented so people would talk to each other more. The plan worked a little too well: now everyone hears everyone — the salesperson on a call, the designers debating a mockup, the recruiter running an interview. Quiet has become the scarcest resource in the modern office.

Where open-office noise comes from

The main source is human speech. Glass partitions, concrete and minimalist furniture look great but absorb almost no sound: voices bounce off hard surfaces and carry across the whole floor. The more people talk at once, the louder each of them has to speak — and the office winds itself up.

What noise does to concentration

Research consistently shows a link between background conversations and falling productivity: the brain involuntarily processes other people's speech even when we are "not listening". People get distracted more often, take longer to return to a task and tire faster. For a business this is a hidden bill — it never shows up in the accounts, yet it writes off hours of the team's work every single day.

Four ways to bring back quiet

Quiet-hours rules cost nothing but last about two weeks — until the next urgent client call. Zoning works better, yet it demands floor space and team moves. Acoustic panels soften the overall hum but give no privacy: the conversation can still be heard. Each of these steps helps — none of them solves calls and confidential conversations.

Why booths are the fastest fix

An acoustic booth solves the problem on delivery day. A Solo assembles in 2–3 hours with no renovation, dust or permits, and certified 35 dB insulation to ISO 11957 (Class A) turns a conversation inside into an unintelligible whisper outside. Ventilation at 250–600 m³/h runs quieter than 30 dB, so the booth stays comfortable even through an hour-long session.

A booth-buying checklist

• Insulation: 35 dB (Premium, ISO 11957) for confidentiality, 25 dB (Lite) for calls
• Ventilation: 250–600 m³/h with fan noise below 30 dB
• Installation: Solo in 2–3 hours, Duet and Quartet in 4–5, no renovation or permits
• Warranty: 10 years on the structure, 5 on electronics, 3 on moving parts
• Budget: Solo Lite from €2,890, Solo Premium from €4,290

Silentbox has installed more than 500 booths across 30+ countries — from the UN and PwC to Uklon, Megogo and Bolt. If your office is loud, the fastest route to quiet has already been invented: it arrives on a truck and assembles in a few hours.
