New Non-invasive Automatic Cough Counting Program Based on 6 Types of Classified Cough Sounds

“…The methods using the measurements of airflow during coughing have also been used in cough counting (14,15). Then the number of cough events was counted off-line by researchers using unfiltered recording of cough sounds obtained with a free-field microphone and a cassette recorder (7,16). In these studies, some researchers have recorded cough sounds with a contact microphone (17)(18)(19), and have measured both airflow and sound pressure in the front of the mouth during coughing (14,(20)(21)(22)(23)(24).…”

Cough medications in children

“…In an early study, the efficacy of two cough-suppressant preparations was assessed in 43 children (aged 2 months-12 years; average 3.6 years) presenting principally with a cough, in general practice 5.
