The background noise level for large offices is typically within the range of 35-40 dB. This specific range is generally considered appropriate for maintaining a conducive working environment that minimizes distractions while ensuring speech privacy.

At this level, the noise is low enough to allow for comfortable conversation and concentration without overwhelming background chatter or mechanical sounds, which can be detrimental to productivity. Furthermore, maintaining a background noise level in this range helps to mitigate the impact of sudden sounds that might disrupt the focus of employees.

Understanding this range is crucial for interior designers and architects when planning spaces, as they need to consider acoustical treatments and materials that can help achieve and maintain the desired noise levels.
