Review: Accurate, and a great value! - I have an older DB meter that does straight readings. I was looking for something that I could use for averaging and finding peak volumes so I gave this a try. It's not at all expensive, is easy to use, and seems to work correctly. I have a high end calibrated source for my older meter, and when I tried it on the Extech it read exactly the correct value. So in a static situation the meter is very accurate. While I don't have any way to test it for peak or average readings, I'm guessing that it's probably pretty darn close. I plan on using this for measuring shop machine noise levels, and also for monitoring sound levels for the PA for a jazz band I play in. If you need a DB meter, this one will do a good job at a great price.

### ⭐⭐⭐⭐⭐ excellent decibel meter
*by J***S on November 15, 2025*

outstanding and highly accurate decibel meter. Is a class 2 meter which is the meter class used by OSHA.

### ⭐⭐⭐⭐⭐ Limited but good product
*by W***G on December 13, 2013*

So far this meter seems to be working alright enough. We have used this on numerous occasions: checking noise level of a window air conditioner to determine if there was any way to dampen the noise level via adding various barriers around window; checking noise level of mowers, tractor, and weed eaters - though we always wear some sort of protective ear gear (plugs or muffs). By measuring equipment we use /have on hand, this gives us a more realistic idea as to what level of noise reduction we want to target / pay for with future replacement or other "noise producing" equipment. I could use this in my business, as I believe the quality is sufficient for the purposes of a very "limited" sound survey.
