A decibel meter is a quite handy tool for acoustic measurements. These devices have diaphragms which respond to the changes in air pressure caused by sound waves on the inbuilt microphone. The unit then accurately converts these electrical values back in decibel units.

Today, Wonderful Engineering brings you the 10 best decibel meters of the market!

“Was looking for an SLM that record data so I could share actual data with law enforcement to support noise ordinance rules. I live next to a business that generates considerable noise sporadically through the day from 7 am to 10 pm six days a week. Calling in disturbances was futile. This meter and its ability to record data all day have made a conversation on solution possible. Very easy to use and download data to turn in graphs, metrics, etc. Also, check out the youtube video on tips and tricks.” – Amazon’s Customer Review.

Reproducibility seems right, but I have no way to verify the accuracy of the meter. For what I used it for, it is perfect. It may be nice to have one with an output jack if you want to get far-reaching about calibration, but for the price, it is hard to beat.” – Amazon’s Customer Review.

I also found this device to be useful in testing everyday items like my hairdryer, car stereo, work copier, etc. I have always wondered what effect daily use of these things was having on my hearing. I tested my hairdryer, and it came out at about 83.2 dBA which is within the 80-90 range for most hairdryers.
