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.
Previous Versions
Here you can find the changelog of SmarterNoise Pro since it was posted on our website on 2019-07-15 11:48:36.
The latest version is 1.042 and it was updated on 2024-04-19 17:40:06. See below the changes in each version.
SmarterNoise Pro version 1.042
Updated At: 2024-04-11
Changes: - Android 14 update.
- Moved settings items into sub-pages.
- Fixed an issue where opening the app from a lock screen notification could cause the current measurement to be lost.
SmarterNoise Pro version 1.041
Updated At: 2023-12-07
Changes: The decibel graph on saved audio recordings can now be zoomed smoothly by pinching. The decibel graph has also been changed to make it easier to see peaks in sound levels in longer measurements.
SmarterNoise Pro version 1.040
Updated At: 2023-10-10
Changes: - You can now change the video playback position by dragging the video image.
- Scrolling of the live decibel curve was made smoother. To save battery life, smooth scrolling can be disabled from the settings.
- The leq curve on the live decibel graph can now be hidden.
SmarterNoise Pro version 1.039
Updated At: 2023-09-21
Changes: - Added medium speed decibel value update setting.
- You can now apply the selected weighting mode to the spectrum analyzer input.
SmarterNoise Pro version 1.038
Updated At: 2023-07-25
Changes: - Added an option to set the live decibel graph display duration to 15, 30 or 60 seconds.
- Added an icon to new measurements in the archive that haven't been opened yet.
SmarterNoise Pro version 1.037
Updated At: 2023-07-06
Changes: The spectrogram range setting was removed. Instead, zoom the spectrogram by pinching and scroll by dragging. In camera mode, long clicking on the spectrogram enables you to interact with the spectrogram, instead of zooming the camera.
SmarterNoise Pro version 1.036
Updated At: 2023-05-26
Changes: Android 13 update.
SmarterNoise Pro version 1.035
Updated At: 2023-02-21
Changes: You can now add text notes to measurements.
SmarterNoise Pro version 1.027
Updated At: 2022-05-06
Changes: Fixed reverse sorting not getting applied when opening the archive.
SmarterNoise Pro version 1.026
Updated At: 2022-04-05
Changes: Added adaptive decibel range setting for the live decibel graph.
