Question

Quizplus · Accepted Answer

30 dB is considered an acceptable sound level for concentrated work as it is relatively quiet, similar to a whisper or a quiet rural area, allowing for focus without significant distraction. Levels like 70 dB (busy traffic) or 130 dB (jet takeoff) are too loud, while 10 dB is quieter than the typical ambient sound in a very quiet room.
