Measurement of room acoustic parameters with an omnidirectional parametric loudspeaker in an converted chapel for choral music performance
(Proceedings of the 11th Convention of the European Acoustics Association Forum Acusticum 2025, 2025-06)An omnidirectional parametric loudspeaker (OPL) is a sound source made of hundreds of ultrasonic transduc ers arranged in a spherical configuration. Each transducer emits ultrasonic waves and, due to ... -
Measurement of the sound absorption coefficient of materials in a reverberant chamber using an omnidirectional parametric loudspeaker
(Proceedings of the 10th Convention of the European Acoustics Association Forum Acusticum 2023, 2023-09)The omnidirectional parametric loudspeaker (OPL) is a sound source that exploits the phenomenon of the parametric acoustic array (PAA) to produce an omnidirectional sound field. It consists of hundreds ...
