Problems caused by differences in instrumentation, computations, and measurement technique are discussed in terms of the utility and comparisons of static acoustic-immittance measurements. Data are provided regarding the short- and long-term variabilities inherent to static measurements. Although our subject pool was relatively small, certain patterns were apparent in the short- and long-term variability inherent to static acoustic-impedance measurements. The intra-event variability about the mean static acoustic impedance was small and varied inversely with probe-tone frequency. Standard deviations were less than 50 acoustic ohms for a 220-Hz probe tone and less than 25 acoustic ohms for a 660-Hz probe tone. Session-to-session variability in static measurements varied little within subjects but varied greatly across subjects. There was little correlation between the mean and standard deviation for within-subject measurements. Standard deviations across subjects approximate a relatively constant proportion (30\u201340%) of the mean static value. The need for large population studies of static acoustic-immittance measurements is noted.<\/jats:p>","DOI":"10.1044\/jshr.2204.677","type":"journal-article","created":{"date-parts":[[2014,7,29]],"date-time":"2014-07-29T17:51:21Z","timestamp":1406656281000},"page":"677-696","source":"Crossref","is-referenced-by-count":6,"title":["Static Acoustic-Immittance Measurements"],"prefix":"10.1044","volume":"22","author":[{"given":"Terry L.","family":"Wiley","sequence":"first","affiliation":[{"name":"Department of Communicative Disorders, University of Wisconsin, Madison, Wisconsin"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael G.","family":"Block","sequence":"additional","affiliation":[{"name":"Department of Communicative Disorders, University of Wisconsin, Madison, Wisconsin"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1310","container-title":["Journal of Speech, Language, and Hearing Research"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/pubs.asha.org\/doi\/pdf\/10.1044\/jshr.2204.677","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,12,23]],"date-time":"2019-12-23T07:12:18Z","timestamp":1577085138000},"score":1,"resource":{"primary":{"URL":"http:\/\/pubs.asha.org\/doi\/10.1044\/jshr.2204.677"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1979,12]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1979,12]]}},"alternative-id":["10.1044\/jshr.2204.677"],"URL":"https:\/\/doi.org\/10.1044\/jshr.2204.677","relation":{},"ISSN":["1092-4388","1558-9102"],"issn-type":[{"value":"1092-4388","type":"print"},{"value":"1558-9102","type":"electronic"}],"subject":[],"published":{"date-parts":[[1979,12]]}}}
