Sound propagation through a rectangular duct of an HVAC system has been investigated in an experimental set-up, in order to evaluate the sound attenuation through different components and the self-noise generated by the airflow. Acoustic and vibration measurements inside the duct were carried out in order to correlate different aspects of noise reduction. The attenuation effects of rectangular straight ducts and of bend ducts with different flow velocities have been evaluated and compared with theoretical formulations.

Abstract
Sound propagation through a rectangular duct of an HVAC system has been investigated in an experimental set-up, in order to evaluate the sound attenuation through different components and the self-noise generated by the airflow. Acoustic and vibration measurements inside the duct were carried out in order to correlate different aspects of noise reduction. The attenuation effects of rectangular straight ducts and of bend ducts with different flow velocities have been evaluated and compared with theoretical formulations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
