Abstract

Provided is an airflow device (100), for example a respiratory support device (100), comprising a flow path (102) along which air is displaceable, and an acoustic absorber (104) arranged along at least part of the flow path. Cavities are defined in a material of the acoustic absorber for absorbing sound. The airflow device also comprises an acoustically transparent layer (106) between the flow path and the acoustic absorber. The acoustically transparent layer is configured to transmit sound in the flow path to the acoustic absorber to enable the acoustic absorber to absorb the sound. The acoustically transparent layer has an exterior surface for exposing to the air in the flow path, and an interior surface facing away from the flow path and towards the acoustic absorber.
