Part of Hyfe's continous research efforts, this paper presents findings from tests conducted to validate the accuracy of the Hyfe cough detection technology. The study focused on two key aspects:

1. Live Trials: The paper describes live trials with 10 volunteers in a quiet indoor setting. Each volunteer contributed 30 coughs, and the Hyfe smartphone apps captured 97% of these coughs. Sensitivity across all smartphones tested was above 93%, with a maximum of 98%. Notably, there were no false positives, indicating perfect specificity.
2. Playback Trials: The study also involved an experimental approach: playback trials using pre-recorded coughs. These trials achieved a high sensitivity of 91%, showing the effectiveness of the system in recognizing cough sounds.
