Abstract
A vibratory respiratory therapy device () has a valve element () on a rocker arm () that opens and closes an opening () during exhalation through the device and thereby generates sound. A mobile phone () with a microphone () picks up the sound generated and has a processor () that converts the sound signal into a sound energy signal in order to measure its frequency. The processor () computes a measure of pressure in the device () by multiplying the detected frequency by a fixed factor and adding a fixed constant to the product. The pressure data is used to monitor patient use of the device.
