Decibel Meter Sound Level Reader 30-130dB(A), Hand-held Sound Noise Meter with Backlight Alarm, Digital Noise Meter Decibel Monitoring Tester Calibrated Audio Noise Volume Measuring Instrument

Wonder how loud the report of your gun is? This was really informative and easy to use. Easy to read and see the display.

Quality and at a fair price. Works as advertised.

Very easy to use. I bought it because my neighbors make too much noise. They are in violation of city ordinance. Now I have proof. And so does my city counsel official.

I have sensible ears and measuring sound of various applications like my motorcycle pipes, horns, firearms and other stuff helps me make adjustments and gives me a warning to use more ear protection. Inexpensive and very useful.

Yes arrived in good shape and easy to work it.

First, there is a battery compartment. Remove the orange casing. Put your fingernail in one of the corners and peel it off. When you have the totally black meter out of the orange case, the battery compartment is on the back. Every meter must be calibrated. The instructions on how to calibrate this meter aren't written for a first-time user. And they instruct you to use a tool and equipment that are not included with this meter. The tool you need is a small screwdriver, like the kind you use for a watch or glasses. The equipment you need is called a “94 dB@1KHz standard sound source” in the instructions. What’s that? An acoustic calibrator. Do a search for acoustic calibrators and they’re all more than 5x the cost of this meter. Once you can get it calibrated, the meter is easy to use. My opinion is if you want a sound meter to conduct a study, collect data, or to use as evidence (like in a complaint about a noisy neighbor), you would be better served to get a higher quality meter. This is a simple, low cost sound meter that can offer general comparisons of sound levels. There are decibel meter apps, but none is considered particularly accurate because they’re all limited by variances among different phones. This meter is a step above those apps.

The decibel meter is easy to use. It with the touch of a button it will hold the max or min decibel reading. It will also give continuous real time readings. I purchased mine to evaluate car exhaust levels. Keep in mind that the decibel scale is not linear so the accuracy is a larger difference in noise than you might think. However, it seems about standard for devices in this price range and above.

it registers decibel levels when there is no sound, so I don't think its very accurate. Also it's frenetic. you turn it own and the decibels go up and down without any rhyme or reason. The instructions leave something to be desired. Calibration method. Carefully plug the microphone head in 1/2 inch hole of standard source (94dB@1KHZ) .. no idea what microphone head they are referring to and the 1/2" hole... so yeah going to send this back.
