Cough detection in headset using microphone and speaker
A recently granted patent (Publication Number: US11918345B2) discloses an innovative apparatus for cough detection integrated into a personal audio device. The apparatus includes a microphone and a speaker, with one or more processors configured to detect a user's cough based on signals received from both components. The detection process involves analyzing the correlation between cough events in the signals, as well as factors like energy levels and changes in device orientation. Additionally, the apparatus can determine the severity of the cough and even identify potential medical conditions such as asthma, croup, COPD, pneumonia, coronavirus, or influenza based on the characteristics of the cough.
Furthermore, the patent also covers a method for cough detection in a personal audio device and a non-transitory storage medium containing instructions for executing the detection process. The technology can be implemented in various electronic devices, offering a discreet and efficient solution for monitoring coughing episodes. By leveraging the capabilities of personal audio devices, this apparatus opens up possibilities for real-time health monitoring and early detection of respiratory issues, providing valuable insights for users and healthcare professionals alike. The integration of cough detection features into everyday devices showcases the potential for technology to enhance wellness and healthcare management in a non-intrusive manner.
