Validation and Evaluation of a Novel Cough Detection Device

Digital cough recording: Participants receive a small, wearable data recorder, wear it during waking hours and keep it on the nightstand during sleep for 7x24 hours. The data is sent to a smartphone application, where a cough detection algorithm converts it into time-stamped cough events. Participants respond to questions on their smartphone once a day for additional context data. The cough events and context data are sent to a secure online database for further evaluation. For the first 24 hours, segments of audio data are sent to be able to validate the performance of the cough detection algorithm. Afterwards, only cough events and context data are sent from the participant's smartphone.
