Bianchi and Baiardi (2008) examined the peak airflow of cough in healthy children and young adults between the ages of 4 to 18 years. All participants were instructed to voluntarily cough following maximum inhalation. They found that the youngest children produced coughs with lower peak airflow compared to the older participants. guage pathologists. Results of the acoustic analysis indicated that cough was remarkably stable across sex and age. Perception of cough was not significantly related to any particular acoustic feature of cough. Perceptual judgment of sex was comparable for both cough and voice samples. However, the accuracy of age recognition was higher for voice samples compared to cough samples. In addition, voice was judged to be healthier and stronger than cough. The clinical implications of the findings are discussed in regard to the use of cough as an index of voice quality.
