About decibels and sound level measurement
The unit for measuring sound is called a decibel. Because the decibel scale is logarithmic, a sound with an intensity that is twice that of a reference sound corresponds to an increase of about 3 decibels. The reference point of 0 decibel is set at the intensity of the least perceptible sound, the threshold of hearing. On such a scale a 10-decibel sound is 10 times the intensity of the reference sound. Highlighting this is important as already a few decibels higher or lower makes a noticeable difference in how noise is perceived.
The preferred method to describe sound levels that vary over time, resulting in a single decibel value measuring the total sound energy over the period, is called Leq. It is however common practice to measure sound levels using A-weighting, which attenuates lower and higher frequencies that the average person cannot hear. In this case the value is called LAeq.
A- and C-weighting
The A-weighting is a standard, commonly used filter that attempts to alter the measured sound pressure levels to more closely match the perception of the human ear. A-weighting makes the sound level meter less sensitive to very high (over 8000 Hz) and low frequencies (below 1000 Hz).
C-weighting also attenuates low and high frequencies, but the attenuation of low frequencies is much less severe compared to A-weighting.
Calibrate:
Calibrate the application using the calibration tool found in the settings menu. Phones and their components vary in quality and setup so you need to calibrate the app in order for the results to be relatively comparable. One suggestion is that you close the window and door to your bedroom or bathroom, turn off appliances, and once its very quiet calibrate the app so the reading is about 30 decibel.
What's New

I am finding this app very useful to document environmental noise levels. I am using it to document a noise complaint. It is very well designed. I audio mode, it records the sound, a decibel graph, and a spectrogram. In video mode, which uses more bytes, it also records a video to document the recording site.

Great app. Using it to monitor environmental noise and it does this wonderfully. You can record video clips of sound levels including time and location info. Feature request: Can you please add a setting to choose whether location recorded in videos are based on name and area or GIS coordinates or both? The last two are useful for specifically referencing a location associated with a video. The specific geolocation could also be added to the vdeo metadata. Thanks for the app.

One of the most comprehensive analytical sound programs I have used with a very simple GUI and lots of functionality, both for manipulation of sound while listening as well as altering recordings that you can make with the app any number of nigh-professional results with very little experience - and in this app, experimentation is JUST as good as experience provided you keep your open mind. -Drew

Screen tends to shut off within an hour. Even though I had the "display on' function on....

Something has happened with the app. Even though the keep screen on is selected it goes off as per screen sleep settings.??? I've lost recordings twice. Also why have a play and a record button, it gets confusing and recorded data gets lost due to wrong selection. You may consider different colours for the buttons maybe.

AutoSave wont work with long sound only recording. Wake up to find empty stand by screen. If not selected auto save even 9 - 10 hours timer record would stay and just need to push save. I would suggest a mode Or even an new app that register noise recoding as per event bits. As of current I can record well but have to find the point of noise complaint. Actually I have half months worth of 9 hours recording which I dont know how to quickly process them.

I am giving the app 3 stars because of poor GPS locator. Location is always wrong. I purchased this app to record audio and video at the house we are building. Changed my rating to 5 stars. Location problem fixed. Can you recommend an app like SmarterNoise Pro that will analyze sound and show decibels and frequencies?

I love the options. I love the layout. I just wish the way it saved the data was different *** edit: I didnt realize audio was the only option. Unfortunately I cant leave my screen on indefinitely in the newer android vs. Had a Quick reply to this review from author! This app is filled hole needed to utilize our under utilized sensors
