Recently, scientists have developed a low-cost microphone system to track the spread of infectious diseases. The device utilizes microphones to detect coughing, sneezing, and other respiratory sounds in order to identify potential cases of infectious diseases. This system is able to detect the sound signatures of various respiratory diseases and alert authorities of a potential outbreak. It also has the potential to be used to monitor the effectiveness of public health interventions, such as vaccinations. This low-cost microphone system could be the key to preventing and tracking the spread of infectious diseases in the future.
