Sound Meter

calibration support. (+4 N20U). light and dark mode. screenshot support. cannot set mic; front mic only. cannot record audio. small and non disturbing ads. easy navigation. simple ui. 5 star if I can select which mic to use.

very good. i used spl meter after this app and it was +- 3db difference

Quick & clear readings -- E-Z to use.

I just now tried a bunch of these, looking for a meter app to help find the correct level that audio should be mixed at, for my recording studio. Sure, I'll calibrate it with an actual meter when I'm finished with renovations but this app is pretty close, if it's not spot on. All the other ones I tried (started from the highest rating down) were way off. They were still only reading 73dB when it was dangerously loud and 43dB when the only noise in the room was a "silent" computer fan.

Ads get disruptive to the point making this app useless when you want to urgently measure the noise. At the launch you get a bunch of full screen ads you cannot skip, so by the time you get to the functionality - it's too late. It's like rotating the ads all the time while this app is running wasn't enough, with those full-screen ads you don't get to use the app, but you see the ads instead. Uninstalling this rubbish.

It seems to give accurate results although I have assessed this from guidelines as to typical noise levels rather than any comparisons with professional meters. I assume the results are linear sound pressure rather than A weighted. It is interesting and it makes me more aware of problematic sources of noise that might endanger hearing.

Love this app, I use it all the time. I had a closed head injury when I was younger so I'm light and sound sensitive. It's great to have a general idea about the atmosphere sound of a place or event or whatever it may be ahead of time so I can plan accordingly. I've used it in so many different environments that I've learned the "norms" for many environments.

Totally disappointed, I just wondered how much quieter something was without a muffler, from a digital point of view, used this app it showed 1 dB difference , given that a motorcycle without exhaust it 'loud', with should be quieter, which we as human beings can hear straight away, not this app thou.

Adds are full-screen and cannot be closed. There is no indication if the SPL level is "A" or "C" weighted, and no way to change it. There is no way to adjust the integratio time for measurements. So basically it is pretty useless.

Excellent. Click the 3-dots for Landscape view. Read its accurate Blog re its limitations, which are an unavoidable consequence of approximating a sound meter on a wide variety of phones. Ads are not excessive. Comparing it on my Oppo A52 against a TOMSHOO A-weighted Noise Detector ($18 from Temu), a -2dB 'Calibration' gave averages within 3dB of the TOMSHOO in the 75-80dB range, with maxima under-reported by ~8dB, and pink noise under-reported by ~3dB. So: convenient for gym music volumes.

This year (2024) works great on my Sony X 1 IV! It has Good calibration! Also It's Very nice to have the upside down screen option to point the main/bottom microphone to the sound sources. Very nice reference scale for different sound levels and the screen colour indication! Good job 👍

Very useful and easy to use. My phones have always measured values whose text descriptions matched the real environment. However, a manual calibration can be performed, to either match the description or even a calibrated sounds meter's reading

Have tried more than a dozen sound level apps. This us about as accurate as any phone app. It's ads are not as intrusive as most. Calibration is not well documented, but works ok "out of the box". Am keeping this one.

Never measures more than 90db. I checked it against an spl meter I have and they were generally in agreement below 90 but for a loud appliance the app pinned at 90b while the meter read 93. Several times I've seen exactly 90 but never above. This should be prominently documented if correct.

Update: years later this issue from old review isn't even fixed. Now with ads. This used to be the best but now other options are better. Old review: Certainly a good and well designed tool but when you click on the button to alternate between graph and text samples it emits a loud noise which influences readings.

Seems good so far. I'm collecting evidence for a noise complaint for knocking in my apartment walls. I like the screen shot function. This is the first time ever in actually considering paying for an app. I'll have to get it calibrated to make an informed decision on it though.

Using a Pixel 6, this app measured within 1 dB of difference of a professional sound meter setup at ~85 dB. I was quite impressed when I tested it. Also has nice features (like calibration offset, and 180 screen rotation to let you point your microphone and use the app).

Sound Meter works pretty well. I am unsure of how accurate it is, but as a sound engineer for small indoor concerts and gatherings, it helps me keep the sound to a good volume without peeking too high.

Super intuitive and easy to use! I love the little scale of example sounds for different sound levels, which is crazy helpful for people who don't have a lot of knowledge for what the numbers mean

Seems consistent with itself, which is valuable, because even if the actual dB measurement is off significantly(I have no means to calibrate this), consistency allows to compare the results(in my case home shop noise reduction efforts) . 3 stars because I cannot rate higher without the proper technical assessment.
