Nice clear display with nice backlight. Calibration seems within a few dB, better than most cellphone "meters", adequate for casual use. Response in "C" mode is flat over most of the audio range. Two "flaws": the head rattles, giving odd jumps in reading; the self-noise level appears to be 38dB SPL, so it will not read very soft sounds, even a quiet livingroom.

Simple to use easy to understand and versatile

I like the accuracy of meter, and light up display and carrying case!!!

I have no complaints. Seems to work great, not over complicated and has a unbelievable backlight

Works well for testing fire alarms for building inspections

At least 10 db off of calibration. Reads 10 db higher then all meters.

Bought this because of a noisy neighbor above my apartment. Local police department uses it so I bought to be able to get same readings they would obtain if (when) I have to create a noise would be nice if it had a wireless connection ability so it could get its own date/time stamp to make a noise record. Right now, I have to keep my tablet beside it to present date/time when I begin measuring. Not a huge deal, but a nice to have. I have to create the video anyway, so I live.

Bought this for 5-6 times more than those low end products expecting to obtain a high quality one. But no, just the opposite. It worked out of box for about 20 mins then the reading went on its own and did not response to any sound anymore. Also it seems cheaply manufactured - metal part looks dull and plastic parts are roughly fit. I am packing it for a return. Will test a various brand other than Extech.

No backlight but even worse the auto off function works when youre recording levels, sooo if you’re not hitting a button every 20 minutes it turns off. It’s useless garbage. I got it to do dosiometering and it turns off. I reviewed the specs and it only measures down to 300hz so really not much better than the application on my phone. I got this as a dedicated sound meter to free up my phone but this thing is too worthless to use. And now I’m past the 30 return period. Don’t end up with garbage like me. Buy an application on your phone for 5 bucks or spend 200+ and obtain a true meter. This one is worthless. It’s like buying a handheld recorded that shuts off 20mins in WHILE RECORDING to ‘save power’. Well save your cash and even more power by not buying this.

I did some testing with the product to see how repeatable it is and found the manual range setting to be more repeatable (and probably more accurate) than the auto ranging. I'm measuring some equipment that has a short duration noise spike, which is typically hard to measure. In the quick mode and with manual ranging, it does a amazing job with this and gives a repeatable reading.I don't have anything to calibrate it with, so I can't comment on accuracy, but it appears to read about what I expect it to. The owners manual is adequate, but the user interface is not intuitive, so hold the manual with the tool, as you will need it again if you have not used the tool in a few months. The memory keep feature works as stated and is simple to use. Quality is good, about what you would expect at this price.

I'm a long time sound meter user, for the purpose of setting up a Home Theater listening system of fifteen plus fore "upgrading" to this unit, I was using a Radio Shack, digital sound meter, the standard on a lot of Home Theater forums. I wanted better because like most, better is, well, just better; security in knowing you're using er beware: this is not a spec'd sound level meter. There are four types of sound meters; lab grade type 0, field/lab grade Type 1, professional general field use Type 2 and the unspecified Type 3 with the lowest calibration standards for general survey work to see if one needs a better quality sound meter. This unit qualifies as a Type 3 as there's no mention in the provided data sheet of this unit being of any type. This is very necessary if one is going buy and use this unit for needed spec'd measurements such as OSHA, lab, legal or law enforcement.Overall, my first impressions were, how light it was. Yes, I'm human and I like my gear to have some heft to it. Along with this sound meter, I purchased a sound meter calibrator. Beware, the first thing I did when calibrating this unit, I pushed the side mounted calibration wheel into the casing and had to take the case apart to "bend" the potentiometer, back into place. Not a amazing sign. The adjustment feature needs to be better secured as I'm a careful user of gear and from my experience, this shouldn't have happened. It's fixed, you've been warned, life is ing forward, the meter reading is what I would characterize as unstable (even on slow, the readings flicker too much) and with a noise threshold of >40dB, does not go low enough for in room measurements. The Radio Shack, digital sound meter is limited to >50dB and yes, at >40dB, this unit is an improvement but at

I picked up one of these to support level match my subwoofer to my main stereo system. It has A and C weighting, and I used C as recommended. It worked amazing for this without needing to understand anything, right out of the box. I also used it to see if the level on the noise machine in my nursery was in the safe range, and adjusted it a little. There's a lot of buttons I probably won't use, honestly, but this is well made. It comes with a wind foam shield which you can use for outside applications. For fast estimates of sound volume (for unofficial purposes, I'm not sure how well calibrated this is) or for comparing two sources to see if they are the same, this is the right tool.I also used this to point out to my wife that the home theater stereo wasn't too loud to do hearing damage. I then pointed out that her yelling at me at how loud the stereo was actually WAS loud enough to do hearing hurt (90db!) and that she should probably volume down. Yeah, that didn't go over so well. I don't recommend using this for spouse volume testing. But for stereo equipment matching, oh yeah, it rocks for that.

This Extech 407730 decibel sound meter is simple to use right out of the box and it works very well. The instructions are easy and simple to understand and everything worked as expected. I had never owned or used a sound meter before, so I wasn't sure what to expect, and someone told me it can be complicated, but it's "So easy a kid could do it", to quote Dr. Leonard "Bones" McCoy from the original Star Trek (Spock's Brain episode)!Having both the "A" and "C" ratings available to use is a amazing thing -- create sure you know which one you should use for your particular app (I did some primary web research to learn more). It measures 40 dB to 130 dB, and I was surprised to search that 43 dB is about my primary background noise in my yard, no wind but birds so, the "Max Hold" function is great; it keeps the highest rating on the display so if you mount the meter remotely, you can still see what it recorded.I mounted it on a primary camera tripod and it worked fine. It actually has a metal tripod mounting thread, unlike some (expensive) digital cameras that use e only nits I can pick are: 1) The small foam wind sock that sticks over the end is beautiful flimsy and it comes off too easily, but not a biggie; and 2) The battery cover is attached with a little Phillips head screw, rather than having a cover that simply snaps on. So you'll need to search a very little #3 Phillips head screwdriver just to remove the batteries, and let's hope you don't have to do this at night or in the [email protected]#$%! seems well created for what it is -- primary plastic case and slightly mushy rubberized push buttons. The display is simple to read (not sure if it has a light, I only used it during the day).Once you familiarize yourself with the instructions, you beautiful much don't have to bother with them again, it's that simple to use. The batteries are the el cheapo type that probably have about 25% of the lifespan of a amazing pair, but otherwise, this is a very nice unit that's probably method overkill for just recording the neighbor's late night parties. I used it for a primary scientific research project and published the results and it worked fine for that.

So far this meter seems to be working alright enough. We have used this on numerous occasions: checking noise level of a window air conditioner to determine if there was any method to dampen the noise level via adding different barriers around window; checking noise level of mowers, tractor, and weed eaters - though we always wear some sort of protective ear gear (plugs or muffs). By measuring equipment we use /have on hand, this gives us a more realistic idea as to what level of noise reduction we wish to target / pay for with future replacement or other "noise producing" equipment. I could use this in my business, as I believe the quality is sufficient for the purposes of a very "limited" sound survey.

Seemingly quite good. I won't address audiophile applications because I am not using the tool in that way. I wanted a device that would monitor sound levels in my neighborhood and on construction websites that I drive to so that I wouldn't have to rely on the assertions of others about actual and prospective noise impacts. This device is quite well suited for that. The MAX function allows you to catch peak impact noises, isolating them from the primary noise levels of the try is device was designed as a temporary or moment-to-moment metering device. Individuals who have the need to trap data and transfer a stream to a computer record should look for a various type of tool or a device with a larger set of metering e company delivers the device in calibrated condition, of course, but is inconsistent in its recommendation for calibration through time. In the accompanying user guide, recalibration is recommended before every use, especially if the instrument has not been used for some time. On the company's web site, recalibration is recommended once a year. Recalibration requires an extra device; Extech offers one that costs twice as much as the meter itself. Independent specialists or employees of sound ysis services won't be bothered by the expense, but casual users of the device may search that to be a huge to swallow to hold a tool tuned up that is used only now and then.I metered a tv broadcast whose volume was set in the overlap location for the device's high and low ranges and found the readings to be beautiful much in agreement -- perhaps 1-2 dB apart. This was a rough eyeball comparison, not a serious attempt to determine the meter's consistency. My verdict is that the unit is easily amazing enough for occasional personal party use and even fast professional determinations to tutorial expectations in a context where more extensive noise level studies are planned.

I have an older DB meter that does straight readings. I was looking for something that I could use for averaging and finding peak volumes so I gave this a try. It's not at all expensive, is simple to use, and seems to work correctly. I have a high end calibrated source for my older meter, and when I tried it on the Extech it read exactly the correct value. So in a static situation the meter is very accurate. While I don't have any method to try it for peak or average readings, I'm guessing that it's probably beautiful darn close. I plan on using this for measuring machine noise levels, and also for monitoring sound levels for the PA for a jazz band I play in. If you need a DB meter, this one will do a amazing job at a amazing price.

Very amazing product. Easy to use and does exactly as described.

It works just fine.

This meter works just fine. It is created of massive duty plastic, for the most part. It takes two AAA batteries, which were included. The measuring range is very adequate for our use. The screen lights so we can see the readout very easily. Handy small tool but not one we would use everyday, so it is adequate for us. Others might wish something a small stronger made.*I received this product in exchange for my honest review. My opinions are my own.*

Amazing quality and pric, quick and slow mode is essential. Relatively directional.

Just what i was looking for

0  

well. I'm getting readings ~15-20db more than our Galaxy Audio "Check Mate," which I trust more than 's a amazing shame because this SPL meter fits wonderfully in my work bag - it's one of the shortest ever, it's just too far off to use.

Super quick shipping and item works as described

Works as described. Seems to be accurate relative to my phone dB readings and is useful for around the house use. I specifically tested mine on different noises around the house, but the basic use was to try the dB readings in a couple of cars prior to sound dampening. Most importantly its accurate. The only reason i would consider giving it less than 5 stars is because it is kinda bulky and would be amazing if it had a few other options....maybe the next gen.

As described. Replaced a high end unit whose body this unit replicates that cost over a thousand dollars and performs well enough for current needs. As a note, while the high end unit with a related body style has a detachable microphone, this unit does not. Still 5 stars as it's not advertised to be removable.

This is amazing and came in calibrated already. My recommendation is only if they can give it some backlighting or give the screen some kind of lighting. Never the less, I still would recommend it.

This has been an perfect tool to present others, true time, how much noise is in a room. Exhaust noise from motorcycles and cars. Lawn mowers etc. DO WISH could save the file so you can present someone later. Huge drawback. Otherwise amazing app. By the way, shouldn't have to pay additional for saving files. The ads that popup should cover that.

Very useful in measuring sound levels coming from my left/right speakers (just to create sure they are evenly matched). But on top of that, the interface is extremely intuitive, clean, ads are discreet (not in-your-face). There is also a helpful description of the sound level ("quiet living room", "normal conversation", "office") which reminds me if my volume is too loud. Thank you for an awesome app.

Seems to me like the 0 (zero) should be all the method to the right not the left. No? Other than that nit it's great. Oh, how does one calibrate the meter? Instructions said to do so. 11/30/20 Still no word from developers as to how to calibrate. Hello!!...

0  

A handy piece of kit. Yea, I would recommend it. I've been a "musician" for the latest forty yes, so being able to relate your output/volume to a moaning clueless idiot neighbor in db's and relating what the law states for noise output at a specific time of day can be quite useful.

This sound level meters works very nicely and is simple to use. Comes with a nice hard storage case as well. One of the cheapest troops that has A & C dB weighting plus fast/slow sampling. I'm an electrical engineer & home theater enthusiast, so the A weighted sampling is amazing for measuring job website and ambient noise levels and the C weighted/slow sampling is amazing for calibrating my home theater speaker levels. I don't have a means of professional calibration, but it does appear to read accurately and consistently. Only true gripe is that the cheap batteries it came with lasted literally 5 mins of use.

Worked amazing at first. I liked the configurability. I wished it had a back light as it gets used in low lighting at the sound board. It is quite a bit larger than I expected.2 months later, all readings over 125db no matter what the setting. I changed batteries, restart it, tried to even re-calibrate but the calibration screw wouldn't turn. No warranty information came with it or even company to call if issues or returns. You wish a amazing price? I'll give you mine for the cost of shipping. It's even too little for a boat anchor.

i'm writing this review to give people information about this purchase. i picked 3 stars just to shoot down the middle, and can't say if it should be 1 star or 5, but i wish to say that i ordered this, knowing it's not some super professional high tech sound meter (those can cost $thousands), but i was expecting it to be something i could use out of the box. the instructions tell you to insert the device into you sound calibrator, and i thought, what's a sound calibrator? i googled it, and it's something that costs minimum $150, and most of them are method more. i don't know if calibration is that necessary for my purposes, and i guess it's fair to say this is just one piece of equipment that's incomplete by itself, but i would think most people ordering a simple, non pro ver of something like this would expect it to just work out of the box.or am i wrong and the calibration is not necessary for my simple, non professional needs for this product? it would be nice to know

0  

I gave this 5 stars BUT, I have suggestions for changes. 1. The numbers inside the meter should present the current reading, or reading within the latest second; not an average since it's already listed at the bottom with Minimum Maximum. 2. I may be wrong, but, it appears that this application constantly records to a file so it's ready to save it. That would cause method too much wear on storage. It should only record to storage when it's selected. Otherwise, this application has nice features and is simple to use.

Excellent for testing the efficacy of sound deadening foam in a home/hobby environment. Create sure phone is in the same orientation and distance from source during your comparative ysis. Not sure about absolute accuracy as a sound meter but you can adjust your phone microphone in the application to match a calibrated meter reading. This is not necessary to me for my purposes and readings seem to fall within the descriptive ranges.

Perfect app. Cannot coment on its absolute accuracy. However, but it seems to be perfectly appropriate as a conparison tool, i.e. to compare various levels of noise using the same device. It was very helpful when I did some diy work at home to reduce the noise coming from two in-line bathroom extractor fans. The comparison between the noise levels before and after various alternatives used to reduce the fan noise served as a very amazing guidance to search the most effective ones.
