Decibel Meter Wall Hanging Sound Level Meter 11 inch Large LED Display Noise Temperature Humidity Meter with Alarm Icons Indicator Wide Applications for Classroom, Studio, Home, Factory

The first one they shipped me was glitchy. It kept showing weird measurements, for example flipping to 130DB in a completely quiet environment. It was really distracting and completely unusable. I tried recalibrating it several times per the instructions. No luck.But I liked the large numbers so much (really easy to read from across the room) that I decided to give it another chance and exchanged it. The second one worked perfectly right out of the box with no issues.I use it in my office when I'm on Zoom calls for work. I tend to speak loudly at the computer and this helps me moderate my volume so the rest of the household doesn't get frustrated. The display includes a color coding of green/red/yellow emojis, so it's easy to tell when your volume exceeds the acceptable threshold.Highly recommended!

Mix an Italian family with an Irish one and there are bound to be lots of talking over one another. Throw in sports on the TV and it gets even louder. I finally broke down and bought this for my mom for Christmas. We just celebrated yesterday and it was startling to see how much quieter everyone got as soon as they saw how loud they were getting. We’ve never had a more peaceful, quiet, but enjoyable family gathering.

I am revising this review because the seller did a really good job of resolving my complaint about the first meter I had failing just after its return period. I wanted to issue a buyer beware on the return polity for it and the seller reached out to me and corresponded with me in a timely manner. The meter itself is exactly what I needed and will do what most people anticipate it will. The tempurature and humidity shown is a plus. I want to thank DP Global and let everyone know that they made it right with me after my first meter failed. I've had other disputes where the seller didn't attempt to do anything for me and so kudos are worth handing out when a seller does the right thing.

This product didn't work for me. It constantly had the noise level around 50-60 dB even in a silent room. I tried recalibrating several times and during the recalibration it looked like it was working correctly -- showing between 1-5 dB -- but then when the recalibration was finished it jumped back up.I read some reviews that others had a similar issue so I gave them a second chance with a replacement unit, but it had the same issue. Will not be giving them a third chance.

UPDATE: After I left my original bad review, the company reached out to me and let me know that this was an exception. The devices were shipped without being calibrated. They replaced the ones that didn't work AND -- the best part -- the new devices came with recalibration instructions. Justifiably, they asked me to update my review, and I've got to say these are a lot of fun and work perfectly. I compared them to my Apple Watch noise monitoring and they're right on. I would definitely recommend purchasing these! Large displays, very bright, and very fast updates. We love them!

I purchased this item to monitor noise level and also humidity. I am a guitarist, so when I practice, I want to be sure I stay under 80db as to not disturb my neighbors. Secondarily, as I have several expensive guitars, humidity control is extremely important. The humidity on this device reads about about 10-12% below the actual humidity level. Disappointingly, that functional part of it is unusable for me. The Temperature readout is accurate. I have nothing to compare the DB readout with, so I am assuming it is accurate. The large color display is awesome. I wish it had a calibration mode for the humidity, like my other digital humidity displays.I have 2 other digital humidity display and one non-electric humidity display, and all 3 of those read exactly the same. For those who don't care about the humidity function, I would recommend this display.

My son was very pleased to receive this as a gift.

it works fine . I have multiple stereo systems, so i gives me the decibel level each system puts out at different volume levels. the battery takes 24 hours to charge , but it will work while charging Which is annoying when i want to move it around . I do like the temp and humidity readouts. There is a formula to determine the watts output of an amplifier. it is complicated and i do not understand it. but 60 DB is 3 watts.
