How loud is too loud?
Government research suggests that the safe exposure limit is 85 decibels eight hours a day. Your hearing can be damaged if you are continuously exposed to high volume sounds.
20dB: very quiet, 40dB: soft,
60dB: quite moderate, 85dB: borderline
90dB: Loud, 100dB: Very loud
110dB: very low, 120dB: dangerous
This decibel meter is ideal for industry and home. It can easily measure the sound level of household appliances, neighbors' pets, urban construction, factories, offices, road vehicles, etc.
Measurement tips:
1) When using the device outdoors, install a windproof ball on the device's head to prevent interference from the wind.
< p>
2) If you want to measure the sound level from A, you cannot ignore the influence of other sources.
3) Measure multiple times to get a relatively stable reading.
Pay attention:
1) Remove the 9v battery if not used for a long time.
2) Do not use it in environments with high temperature or humidity.
