Description
Sound levels are usually expressed in a logarithmic scale called the decibels (dB). The decibels cannot be added or subtracted directly.
Each operation between decibel values requires to convert the sound level back to a linear scale using an antilog function.
The dB calculator app allows the direct addition or subtraction of dB levels. The app uses the following formula:
A + B = 10*LOG10(10^(A/10) + 10^(B/10))
For instance, 5dB + 5dB returns 8dB (3dB is added when doubling the sound level) or 1dB + 2dB = 4.5dB.
What’s New
Version 2.2.0
Ensuring the app runs smoothly in iOS 18.
Ratings and Reviews
Crashes on Launch
I can't actually review the app because it doesn't open on my iPhone 6s Plus running iOS 10. I hope this is a temporary bug.
Nice little App
Useful if you need to add or subtract dB levels.
