• Description:
  Physicians have used the presence and characteristics of cough as a diagnostic tool for many years. Researchers have shown that cough sound analysis can assist in the diagnosis of respiratory disease [1]. Important considerations such as cough intensity and duration may affect the sounds produced by the lungs. To reliably classify cough sounds, these considerations must be addressed. Measurement of cough air flow simultaneously with sound has several advantages. Indices can be derived which estimate the forcefulness of a cough. This information is useful in determining the repeatability of cough sound measurements. Additionally, flow indices could augment existing diagnostic algorithms to improve their ability to distinguish subjects with different types of pulmonary disease. Our challenge was to record the cough air flow accurately without affecting the fidelity of the sound measurement made at the mouth. A system was designed for this task. Hardware was developed to record sound with minimal interference. Reconstruction software was written to estimate flow at the mouth, based on a flow measurement recorded where it would not alter the sound. [Description provided by NIOSH]
