Description

This lecture covers the radiation properties of a circular piston, discussing its directivity, radiation impedance, and near field behavior in different mounting conditions. It explores the acoustic pressure due to the piston's surface elements, the directivity factor, and the complex expressions for the near field. The lecture also delves into the radiation impedance of a free piston and models such as the piston in an infinite screen, a box, and at the termination of a duct.
