DECIBEL SOUND CHART PROFESSIONAL
Because this is a professional tool, it’s much more suited to the sort of monitoring that requires you to leave it set up. Like a lot of the more expensive meters, it has a tripod mount that makes long-term monitoring much easier. Plus, like the Extech 407730, it has both a digital display and an analog barcode, which is useful for reading noises that are fluctuating. The LCD screen is easy to read and actually lights up a lot better than any of the other decibel meters we’ve featured. It can measure both A and C weightings and fast and slow weightings, which makes it suitable for measuring pretty much any level of noise. It’s best if you buy it with the corresponding Reed calibrator, but that’s going to set you back another $160. So, you can really trust the reading you get from this thing. And, it meets IEC Type 2 requirements, which is a standards authority that determines the accuracy of measuring tools. It’s accurate to +/- 1.4dBA, which makes it the most accurate device on here. It’s the accuracy of this device that sets it apart. That might sound like a lot of money, but it’s a drop in the ocean of a major court case. In fact, this version – which retails at around $200 – isn’t NIST certified, but you can buy one with a certificate of traceability to NIST for an extra $250. This is more designed for audio engineers, professional acoustics engineers, and people who need an audio recording that will stand up in a court of law. This isn’t a decibel meter to see if your baby room is quiet enough or your neighbor is too noisy – that is, unless you’ve got money to burn. The reason it costs so much more is that it’s designed for professionals. It’s by far the most expensive and was an obvious choice as our Premium Product. The final product on our list is the REED Instruments R8060 Sound Level Meter.
