75 dB(A) is the upper end of what most people meet at home. It is the level at which the NIOSH exposure curve is still 'no limit', but the margin is small: 10 dB more and you are at the 85 dB damage threshold.
Is 75 dB loud?
Yes. 75 dB is loud enough to be tiring and to interfere with conversation, but it will not damage hearing. Long shifts at 75–80 dB in factories are considered safe for hearing under US and EU rules, although employers must start monitoring at 80 dB in the EU.
| Zone | Moderate (60–84 dB) |
|---|---|
| Safe daily exposure | no limit for hearing safety (below the 85 dB threshold) |
| Compared with 60 dB (normal talk) | 15 dB louder — sounds roughly 2.8× as loud, 32× the sound energy |
| Compared with 85 dB (damage threshold) | 10 dB quieter — sounds roughly 2.0× as quiet, 10× the sound energy |
Measure it yourself
Open the free online decibel meter on your phone or laptop and hold it where you want to measure. Readings from a built-in microphone are estimates within a few dB; for a legal noise complaint use a calibrated sound level meter.
