Adult, English-speaking patients who were undergoing audiometric assessment by audiologists at an academic health system as part of their prescribed care were invited to use the EarBone app. Best-ear bone-conduction thresholds determined by the app and the gold standard audiologist were compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Forty subjects with varied hearing thresholds were tested. Sixty-one percent of app-determined thresholds were within 5 dB of audiologist-determined thresholds, and 79% were within 10 dB. Nearly all subjects required assistance with placing the bone oscillator on their mastoid.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Best-cochlea bone-conduction thresholds determined by the EarBone automated smartphone audiometry app approximate those determined by an audiologist. This serves as a proof of concept for automated smartphone-based bone-conduction threshold testing. Further improvements, such as the addition of contralateral ear masking, are needed to make the app clinically useful.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/0003489419828770","type":"journal-article","created":{"date-parts":[[2019,2,12]],"date-time":"2019-02-12T15:34:27Z","timestamp":1549985667000},"page":"508-515","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Automated Smartphone Audiometry: A Preliminary Validation of a Bone-Conduction Threshold Test App"],"prefix":"10.1177","volume":"128","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0350-7483","authenticated-orcid":false,"given":"Nicholas A.","family":"Dewyer","sequence":"first","affiliation":[{"name":"Department of Otolaryngology, Massachusetts Eye and Ear, Boston, Massachusetts, USA"},{"name":"Department of Otology and Laryngology, Harvard Medical School, Boston, Massachusetts, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patpong","family":"Jiradejvong","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, UCSF, San Francisco, California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David S.","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, UCSF, San Francisco, California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7266-9868","authenticated-orcid":false,"given":"Jacquelyn D.","family":"Kemmer","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, UCSF, San Francisco, California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer","family":"Henderson Sabes","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, UCSF, San Francisco, California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charles J.","family":"Limb","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, UCSF, San Francisco, California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2019,2,11]]},"reference":[{"key":"bibr1-0003489419828770","unstructured":"World Health Organization.
