  "description": "<p>Real sound sources have unique directional properties unlike simple idealised sources such as monopoles. Measur-</p>\n\n<p>ing the directivity patterns of sound sources typically involves measuring sound power using pressure microphones</p>\n\n<p>on a spherical grid surrounding the source. This approach is not very practical and is costly due to hardware</p>\n\n<p>requirements. This paper proposes a reduced-complexity source directivity measurement approach. The spherical</p>\n\n<p>harmonic decomposition of the sound field at a small number of measurement points around the source is first</p>\n\n<p>obtained. Both pressure and its higher-order spatial derivatives are then calculated to estimate source directivity that</p>\n\n<p>best matches a fixed-order model. The proposed approach is validated to assess its utility using eight second-order</p>\n\n<p>measurements around a loudspeaker. The estimated directivity functions closely matched the manufacturer data,</p>\n\n<p>particularly at low and mid-frequency bands.</p>",
