How loud is 70 decibels?
70 dB is a vacuum cleaner, a busy office or the chorus of summer cicadas. It is safe for your hearing, but prolonged exposure is tiring and makes concentrating harder. You have to raise your voice slightly to be understood.
Loud
Noisy, like busy traffic or a vacuum cleaner. Tiring over time.

Is 70 dB safe?
Yes. 70 dB is well below the 85 dB threshold where hearing damage begins, so there is no exposure limit.

Where you hear 70 dB
70 dB is where noise starts to feel intrusive. A vacuum cleaner, a busy restaurant at dinner time, a washing machine on spin or a main road heard from the pavement all sit around here. The WHO 2018 guidelines use 70 dB LAeq averaged over 24 hours as the upper limit for yearly leisure noise exposure.
Practical tips at 70 dB
Short periods at 70 dB are harmless, but a whole day in this range is tiring and makes concentration harder. If you work in a 70 dB space, take quiet breaks and use the meter’s Leq over an hour to see your real average. Noise-cancelling headphones at low volume are gentler than turning music up to mask the room.
