From the results of the non-linear regression analysis, the determination coefficients showed high values (greater than 0.7) for the three types of microphones investigated. Furthermore, for the cough sounds recorded with the bone conduction mic and the smartphone mic, including the height variable in the revised prediction equation of the cough peak flow improved the accuracy of the estimated cough peak flow.
