Airflow control by auditory feedback: respiratory mechanics and wind instruments.
The auditory signal provided by a soprano recorder in a breathing circuit can help human subjects to regulate inspiratory and expiratory airflow rates at constant preset levels. This method of airflow control is useful in studies of the static and dynanic mechanical properties of the lungs and may have additional applications in human respiration physiology.
