文摘

Sound source signal is reconstructed via AP-TR combined with shear flow correction. More accurate sound source signal can be obtained by AP-TR in environment with flow. AP-TR offers an alternative way to reconstruct sound source signals with airflow. Sound field measurement in a wind tunnel is conducted to prove the proposed method.
