Muscle activation and sound during voluntary single coughs and cough peals in healthy volunteers: Insights into cough intensity

In conclusion, effort and operating volume have important influences on cough mechanics but modulate muscle activation, pressure and cough sound amplitude and energy differently. Consequently, these cough sound parameters poorly represent voluntary cough mechanics and have limited potential as a surrogate intensity measure.
