Exposure to noise levels of 85 dBA is generally considered safe for up to 8 hours a day according to occupational safety guidelines. For each 3 dB increase in noise level, the safe exposure time is halved; for example, at 88 dBA, the recommended exposure time is reduced to 4 hours. Prolonged exposure can lead to hearing damage, so using hearing protection is advisable when exposed to such noise levels for extended periods.

How loud is 85dba?
85 dBA (decibels A-weighted) is considered a moderately loud sound, comparable to the noise level of heavy traffic or a vacuum cleaner. Prolonged exposure to sounds at this level can potentially lead to hearing damage, so it's advisable to use hearing protection if exposed for extended periods. In everyday settings, it's loud enough to make conversation difficult without raising one's voice.
