What should an office environment sound level be?

• A. below 60 dBA
• B. below 65 dBA
• C. below 70 dBA
• D. below 75 dBA

Answer: (B)

Maintaining a comfortable office is about keeping background noise low enough to hear conversations clearly while still allowing normal activity and HVAC hum. Keeping the ambient sound level under about 65 dBA strikes a practical balance: it’s high enough to reflect real office conditions, but low enough that typical conversations (which sit around 60 dBA at close range) remain intelligible without shouting. Levels below 65 dBA support focus and privacy better than higher levels, while still being achievable in most office designs. Options that are stricter (below 60 dBA) can be too limiting in real offices, and those that allow 70 or 75 dBA would make conversations harder to understand, reducing comfort and productivity.
