The NNE is automatically computed from the voice signals using an adaptive comb filtering method performed in the frequency domain. Experiments with the voice samples show that the NNE is especially effective for detecting glottic cancer, recurrent nerve paralysis, and vocal cord nodules. Specifically, when glottic cancer is represented in terms of the T classification adopted by the UICC (Union Internationale Contre le Cancer), glottic T2\u2013T4 cancer can be perfectly discriminated from normal samples, but 22.6% of patients with glottic T1 cancer are incorrectly classified as normal, with an error rate of 9.4% for normal subjects.<\/jats:p>","DOI":"10.1121\/1.394384","type":"journal-article","created":{"date-parts":[[2005,10,7]],"date-time":"2005-10-07T18:35:41Z","timestamp":1128710141000},"page":"1329-1334","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":193,"title":["Normalized noise energy as an acoustic measure to evaluate pathologic voice"],"prefix":"10.1121","volume":"80","author":[{"given":"Hideki","family":"Kasuya","sequence":"first","affiliation":[{"name":"Department of Electronic Engineering, Faculty of Engineering, Utsunomiya University, Utsunomiya 321, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shigeki","family":"Ogawa","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Faculty of Engineering, Utsunomiya University, Utsunomiya 321, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuhiko","family":"Mashima","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Tokyo Medical and Dental University, School of Medicine, Tokyo 113, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoshi","family":"Ebihara","sequence":"additional","affiliation":[{"name":"Division of Head and Neck Surgery, Department of Surgical Oncology, National Cancer Center Hospital, Tokyo 104, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","container-title":["The Journal of the Acoustical Society of America"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/pubs.aip.org\/asa\/jasa\/article-pdf\/80\/5\/1329\/12160904\/1329_1_online.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/pubs.aip.org\/asa\/jasa\/article-pdf\/80\/5\/1329\/12160904\/1329_1_online.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,7,20]],"date-time":"2023-07-20T04:17:10Z","timestamp":1689826630000},"score":1,"resource":{"primary":{"URL":"https:\/\/pubs.aip.org\/jasa\/article\/80\/5\/1329\/682599\/Normalized-noise-energy-as-an-acoustic-measure-to"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1986,11,1]]},"references-count":0,"journal-issue":{"issue":"5","published-print":{"date-parts":[[1986,11,1]]}},"URL":"https:\/\/doi.org\/10.1121\/1.394384","relation":{},"ISSN":["0001-4966","1520-8524"],"issn-type":[{"value":"0001-4966","type":"print"},{"value":"1520-8524","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[1986,11]]},"published":{"date-parts":[[1986,11,1]]}}}
