Sound Meter Pro
SPL(sound pressure level) meter app uses your microphone to measure noise volume in decibels(db), and shows a reference. We calibrated a lot of android devices using an actual sound meter with dB(A).
REMEMBER!! Most smart phone microphones were aligned to human voice (300-3400Hz, 40-60dB).Therefore maximum value is LIMITED by manufacturers, and very loud sound(100+ dB) cannot be recognized. Moto G3 (max.80), Galaxy S6 (85dB), Nexus 5 (82dB), HTC Desire(82dB)...You can trust the result in routine-noise levels (40-70dB). Please use it as an auxiliary tool.
Vibrometer uses the phone sensors to measure vibration or an earthquake, and it shows a reference as a seism detector.
The measured values are related to Modified Mercalli Intensity scale (MMI). If it is inaccurate, you can calibrate it so that maximum value is about 10-11.Please use the results only for reference because android devices have a wide variety of performance and sensitivity.

Vastly limited by the microphone of your phone. They tell you this in their blog...after you've bought it. Phone are designed to pick up voice frequencies. Being a musician who needs to know how loud music is on stage and in my practice situation, this app is worthless to me. They should take the "Pro" out of the name. It's a toy.
I taught theatrical sounds design at a major university for years. I had my students install this app on their phone to help analyze the acoustics of the theatre. It worked well. I later discovered they started using it to analyze classrooms around campus. It is easy to understand and use. While not as precise as dedicated sound meters it works well for a strong general understanding of the space.
I like the app, but I wish measurement would continue when the screen is off. Also would be useful to add a chart of lengths of safe exposure at each dB level, like OSHA and others provide. Not vital, but it would save users a step.
Very convenient and pretty accurate. It would be nice if the app had a chart with safe exposure times of each decibel level.
I am undergoing speech therapy for a condition seen in Parkinson's patients where their voice just gets weaker and weaker. This application is great for showing me with a numerical score just how loud my voice it. Gives me a target to work against when I practice.
I've had good luck with these tools, they are really Accurate, if you're going to buy any of these tools your best bet is to get MiniTool set.. It only costs about $1 than any individual tool app..
Great app - conveniently integrated into my mobile device, and remarkably accurate when compared with very expensive instruments.
Excellent and accurate
Excellent tool to explain to people in a simple way how loud something is or more importantly... Is not.. Great job!!
It would be great if you apply metric System. Not very one understand "ft"
lm not sure if i shoyld expect it do do sonething else, but it does what i expect it to very well. i love this handy app ...
Great i compare it to a calibrated db meter and i was amazed to see the accuracy
Great for check nuisence noise sources. Very accurate too.
Works as intended with no extra bloat. Very accurate
whatever one needs for a quick and clean audio dB-tester
Nice app. Works reliably
Will not function with Android 9.
I would give it 5 stars if it came with instructions for calibrating it.
App is working as before now, thank you!
Very easy to use.
Great and trusty meter
The best one so far yet
It does what I need it
Precision calibrated below 100dB levels.
Does what I think it should.
Works as expected
If you read the developer's own description, then their thirteen measured intervals should be switched in the next version to 3dB spacing from 44-80dB. Three decibels is a doubling of sound -- perceptible to many people -- and the app's documentation says you can't really trust the last three readings even *if* they switched to the above improvement over the current version.. But it would be an good change, given the limitations above eighty decibels of many phones (and the limited accuracy of Sound Meter Pro)
