What is the recommended noise level for a private office setting?

In a private office setting, the recommended noise level typically falls between 35 and 45 dBA. This range is considered optimal for maintaining a comfortable working environment that minimizes distractions and supports concentration. Levels below this range may lead to an overly quiet atmosphere that could result in unproductive behavior or discomfort, while levels above this range can become disruptive, making it difficult for employees to communicate effectively and focus on tasks.

The reason this specific range is suggested is based on research that indicates the importance of a balanced auditory environment for cognitive performance and overall well-being in work settings. It allows for normal conversation, telecommunication, and daily tasks without overwhelming background noise, facilitating a productive workplace.

Choosing values that fall outside this recommended range, such as the higher levels or substantially lower levels listed in the other options, would likely detract from productivity and comfort, leading to potential stress and decreased work performance among employees.
