No, Airthings monitors integrate microphones that sample 60 milliseconds of ambient audio at 6-second intervals. The ultra-short sampling interval makes it impossible to reconstruct speech or to even identify the source of the audio. The raw audio samples are collected and used to calculate weighted noise levels in decibels on the monitor. The calculated levels are then sent to the cloud and include average, maximum, and minimum values. The raw audio samples are only stored on the monitor for a few milliseconds and are deleted once the calculations have been performed.
