Cough monitoring during COVID-19 pandemic

Muffling caused by the wearing of face masks has been a problem for cough recording systems using free field microphones during the COVID-19 pandemic.

Smith et al. investigated the potential of an algorithm capable of using only the VitaloJAK’s contact sensor data and found that “Single channel processing (contact sensor only) maintained sensitivity, median 100% (99.7-100.0)”. It concludes that the processing of contact sensor data is an acceptable alternative to two-channel recording for the VitaloJAK cough monitoring system.
