Decibel Meter, RISEPRO® Digital Sound Level Meter 30 – 130 dB Audio Noise Measure Device Backlight MAX/MIN, Data Hold Auto Power Off Dual Ranges HT-80A

I use it on HVAC to prove how silent the indoor and outdoor units are They have freaking awesome I love mini splits and I love this decibel reader

I wanted a sound level meter that could capture peak noise levels like rifle shots. Many of the lower priced ones said they only measured the average levels. This one was supposed to measure shot noise levels and it works very nicely for that. Just turn it on, hit min/max and it will start storing the min and max values. After the event of interest has occurred, press min/max and the peak max value appears, press min and the smallest min value appears, press min/max again and the previous max level and min level are cleared and the unit is back in the min/max measuring mode again. The unit couldn't be easier to use and the readings seem accurate.

I was filming nighttime truck noise, I first cussed at it for not having the backlight. I guess I should've read the manual. Pressing the hold button for 3 sec did the trick. Measuring the aggregate noise level doesn't seem possible though. I'd guess many people buy these meters to gather evidence for noise complaint. And the city ordinance often mandate the aggregate level, not Max. The wind shield foam falls off way too easily. They'll need to improve it so that it will snap on/out rather than slide in on slippery metal. Or, at least add some rubber on the foam or the mic. I can't testify as for the accuracy. I compared it with a highly rated Android app, and this meter seemed to be 1-2 Db higher. But phone apps are not supposed to be that accurate, so I wouldn't know which one is more correct.

Pretty cool device, works perfect would recommend!

I have no way of calibrating the device, but it seems to be more responsive and repeatable than my iPhone app. Used to monitor a dehumidifier performance. Room background around 38 Db, Unit level on high at 3 feet around 58 Db, at 10 feet around 50Db. Those readings compare well with readings taken by a review site with better instrumentation. Good unit for casual work. Decent quality, easy to use

I purchased this devices for a single purpose: measure road and wind noise in number of new cars I was going to test drive. To my surprise I found that a very noisy road did not create an adequate rise in reading numbers. My wife confirmed that our perceptive noise level was way worse than 1-2db difference the device would indicate. Upon examining the specs I found that the device only reads noise up to 4kHz, while the road noise had plenty of high frequency component to it, even to my musically-deaf ears. So I don't mean to berate the device for it was not designed for, but I'm sure most of people would buy it like me, "this measures noise level? cool, give me one". Well, it does and it doesn't, and it's just not quite fair in my opinion. This should have come with a big disclaimer: "Measures 1/5th of what your ear can hear." Also, on a minor note, the foam thingy is not attached in any way and we lost in in our second car, quite frustrating because it really became useless after. It registers much higher numbers without the sponge.

As an aging entertainer, it's long been obvious that audiences in their later years know only two volumes, "too loud" and "I can't hear you". With venues ranging from living rooms to fire halls, the answer is to actually measure the audio level. This inexpensive device provides a quick check without opinion. By placing the meter at approximately the same distance from the speakers, the volume can be adjusted with consistency. Exact accuracy for my use isn't as important and being able to establish a relative set up. It will get used over 100 times this year. Can you hear me now?

it works but I don't have anything I can compare it to. Just making sure it doesn't get too loud and this definitely helps.

Good

Very inaccurate. Bought this to set up home theatre speakers and while using test tone at constant volume the meter kept jumping 4 to 5 decibels a second . Free sound meter app on mobile phone is a lot more accurate

I use to measure noise coming from my in line duct. It work perfectly how many time can i use and how long this item will last who knows..

no funciona bien marca mucho ruido con un simple sonido normal. le hace falta algún tipo de calibración pero no se especifica en la publicación no me sirve sin saber como calibrarlo.
