Good meter: Sound & Noise Meters

This meter is very light. It comes in a large suitcase. The measurements were pretty close to what I know some levels. I've tested it alongside power tools, music at various volumes, car engines, and handmade noises. He registered the lowest volume, but was close. I would say with an error. The screen is backlit and very easy to read. There is a 1/4-20 mount on the back for mounting on a tripod. There is a 3.5mm jack output to control another device. I believe this meter can act as a safety…

As far as I can tell it works fine!

Unfortunately I don't have a reliable comparison, but when tested under normal conditions it showed typical noise levels. I'm hoping to correlate this with a known good device at some point, but for now it seems to work well for estimating changes in noise levels. With an easy-to-read backlit screen and simple controls, nothing stands in the way of this device's ease of use. The case is a generic cheap blow molded case with flexible plastic hinges that are sure to fail with enough use. It's a…

  • Absolutely amazing!

Invaluable for audio enthusiasts or professionals.

Some instruments are essential in the audio world. Function/waveform generators, oscilloscopes, multimeters and decibel meters. In terms of price and performance, this should definitely be on your list. The display is perhaps a bit dated and still uses AA batteries (hello, we live in the lithium age). But a dB meter that weighs A and C for less than $50, I think I can stand removing a set of rechargeable AA batteries on a regular basis. ), so I'd say it's pretty accurate. I can do further…

  • Automatic shutdown and overload indicator

Inexpensive noise meter!

This sound level meter is ideal for a variety of situations - at home, on construction sites, at work. It's an insightful tool that can help you understand the noise levels around you and the potential damage to your hearing. Based on the measured decibel value, you can tell if you are exposing your hearing to unsafe levels. This will give you an idea of where to wear your hearing protection. What you get is the sound level meter itself, a 9 volt battery, a microphone cover, a screwdriver…

Shots and Blenders

This meter has everything you need to start measuring sound. It also includes a sheet explaining the different settings and what they mean, such as: B. Different tone reports - average or maximum, called A or C. I found it to work as the instructions said it would. The BTMeter is said to come calibrated, which is good. during a year. I am unable to produce calibrated audio so I took the company's word for it. I ran what is called a sniff test to measure sounds where I have a reasonable idea of…
