By using a seven\u2010element array to invert the position and angle of a sound source, the relative time delay value of a pair of microphones on the vertical axis of the coordinate system is used to determine the elevation angle polarity and realize the omnidirectional sound source positioning. The array parameters, sound velocity, array size, horizontal deflection angle, elevation angle, and sound source are analyzed, and the error method is proposed. The sound source data was measured using the microphone array perspective, and a new Cartesian coordinate system was established based on the observation angle of view for omnidirectional positioning calibration of the sound source. The simulation results show that the position error of the method is about 0.01% and the angle error is about 0.005%, with high calibration accuracy. The actual measurement results show that this method can effectively calibrate the sound source azimuth, the error rate of the source coordinates is around 10%, the horizontal declination angle error is less than 5%, and the elevation angle error is less than 8%. Appropriately increasing the spacing of the array will have a better calibration effect in an actual complex experimental environment.<\/jats:p>","DOI":"10.1155\/2018\/2317853","type":"journal-article","created":{"date-parts":[[2018,10,4]],"date-time":"2018-10-04T23:36:30Z","timestamp":1538696190000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Sound Source Omnidirectional Positioning Calibration Method Based on Microphone Observation Angle"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6877-5641","authenticated-orcid":false,"given":"Xu","family":"Yang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3204-3457","authenticated-orcid":false,"given":"Hongyan","family":"Xing","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4153-7010","authenticated-orcid":false,"given":"Xinyuan","family":"Ji","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,10,4]]},"reference":[{"doi-asserted-by":"publisher","key":"e_1_2_12_1_2","DOI":"10.1016\/j.heares.2017.11.008"},{"doi-asserted-by":"publisher","key":"e_1_2_12_2_2","DOI":"10.1016\/j.csl.2016.10.004"},{"doi-asserted-by":"publisher","key":"e_1_2_12_3_2","DOI":"10.1109\/ACCESS.2017.2720746"},{"doi-asserted-by":"publisher","key":"e_1_2_12_4_2","DOI":"10.1016\/j.ymssp.2016.11.011"},{"doi-asserted-by":"publisher","key":"e_1_2_12_5_2","DOI":"10.1016\/j.robot.2016.07.008"},{"doi-asserted-by":"publisher","key":"e_1_2_12_6_2","DOI":"10.1016\/j.ymssp.2016.12.003"},{"doi-asserted-by":"publisher","key":"e_1_2_12_7_2","DOI":"10.1109\/TSMC.2017.2676022"},{"doi-asserted-by":"publisher","key":"e_1_2_12_8_2","DOI":"10.1109\/TSMC.2017.2694020"},{"doi-asserted-by":"crossref","unstructured":"ZhuQ.
