SoundMeter 4.1 offers percentile-exceeded sound levels
SoundMeter 4.1, which is now available for download on the App Store, offers percentile-exceeded sound levels (Lx) via in-app purchase.
With the new upgrade, SoundMeter can display L10, L50, L90, or any percentile between 1 and 99. Percentile exceeded sound levels are also available in the Octave Analyzer tool (sold separately).
Also new in SoundMeter is the ability to set the meter to automatically stop after an arbitrary amount of elapsed time from 1 second to two weeks.
The Dosimeter and Octave Analyzer tools (sold separately) can also be set to automatically stop after a user-defined period of time.
