UNI-T Decibel Meter Ut353Bt, Digital Sound Level Meter 30-130Db Audio Noise Volume Measure Device Free App for iOS/Android, Max/Min Fast/Slow Data Hold LCD Back

Makes setting sound a lot easier. Very responsive.

I love it overall, also the app is nice. The most useful is that it produces a pdf report of the capture.

My two sons, age 7 & 8, are rarely aware of how loud they are at times. Part of this is just that they're boys, part of it is they are somewhat neurodivergent and aren't always aware of themselves. Most of the time it's fine, in public they've been learning to control themselves. However, car trips can be painful so I've been searching for a way to "gamify" their volume in the car. This is the perfect solution because they're both into technology and tools.I've already explained to them what this is, how it works, what decibels mean, and where permanent hearing damage can occur. They were very into the concept and how their voices could be measured for loudness. We agreed to set the alarm on the app at 85 db and that if they make it through a car trip without setting off the alarm they get a prize.First trip out worked perfectly! They managed to stay under 85 db and won their prize!The unit itself seems well-made. I can only judge the accuracy anecdotally, but it seems about right. My noisy refrigerator runs about 58 db. Very quiet conversations run about 60 db. I don't think this is a professional grade unit but, for what I'm trying to do it's a nice little unit at a nice price.

I use this meter to record noise from neighbors at night that exceed the city ordinance and disrupts my sleep.After using it for about 2 weeks I’m finding it’s starting to skip several seconds at a time .. literally 2-10 seconds between each reading .. so stomping and banging happens and when I go check the data on my phone from the meter… there are huge gaps in the information .. and most often the moment I needed metered was not recorded in the data. Even at best one of the two meters I bought (both are this red meter) has started recording every 2 seconds consistently.. I’ve changed the batteries, turned it off and on, disconnect and reconnect to the phone.. after a minute or so it’s back to only recording every 2 seconds.. i don’t see any option to contact the seller for support thusly I’ll share my experience with the public. Otherwise having calibrated it I can say it is accurate.. but connecting your phone and recording for a period of time then it goes skitz..
