The resulting beam of sound travels farther, with less dissipation in air, than horn loudspeakers, and can be sent to isolated audience targets, unlike line array loudspeakers. The parabolic loudspeaker has been used for such diverse purposes as directing sound at faraway targets in performing arts centers and stadia, for industrial testing, for intimate listening at museum exhibits, and as a sonic weapon."@en }
