Measuring ear-canal acoustics in young children can be challenging, and relying on normative real-ear-to-coupler difference (RECD) transforms can lead to large fitting errors. Acoustic immittance measures characterize the impedance of the ear and are more easily measured than RECD. Using 226\u2009Hz tympanometry to predict the RECD is more accurate than using age-based average RECD values. The current study sought to determine whether wideband acoustic immittance measurements could improve predictions of wideband real-ear-to-coupler difference (wRECD). 150 children ages 2\u201310\u2009years with intact tympanic membranes underwent wRECD and wideband acoustic immittance measures in each ear. Three models were constructed to predict each child's measured wRECD: the age-based average wRECD, 226\u2009Hz admittance wRECD, and wideband absorbance wRECD. The average age-based wRECD model predicted the child's measured wRECD within 3\u2009dB in 62% of cases, but both the 226\u2009Hz admittance and wideband absorbance wRECD were within 3\u2009dB in 90% of cases. Using individual 226\u2009Hz or wideband absorbance to predict wRECD improved the accuracy and precision of transforms used for pediatric hearing aid fitting.<\/jats:p>","DOI":"10.1121\/10.0020660","type":"journal-article","created":{"date-parts":[[2023,8,15]],"date-time":"2023-08-15T12:54:43Z","timestamp":1692104083000},"page":"991-1002","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":2,"title":["Predicting wideband real-ear-to-coupler differences in children using wideband acoustic immittance"],"prefix":"10.1121","volume":"154","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0733-7269","authenticated-orcid":false,"given":"Ryan W.","family":"McCreery","sequence":"first","affiliation":[{"name":"Audibility, Perception, and Cognition Laboratory, Boys Town National Research Hospital 1 , Omaha, Nebraska 68131, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anastasia","family":"Grindle","sequence":"additional","affiliation":[{"name":"Pediatric Audiology, UW Health American Family Children's Hospital 2 , Madison, Wisconsin 53792, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7251-1879","authenticated-orcid":false,"given":"Gabrielle R.","family":"Merchant","sequence":"additional","affiliation":[{"name":"Translational Auditory Physiology and Perception Laboratory, Boys Town National Research Hospital 3 , Omaha, Nebraska 68131, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffery","family":"Crukley","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Department of Speech-Language Pathology, University of Toronto 4 , Toronto, Ontario M5G 1V7, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth A.","family":"Walker","sequence":"additional","affiliation":[{"name":"Department of Communication Sciences and Disorders, University of Iowa 5 , Iowa City, Iowa 52242, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","published-online":{"date-parts":[[2023,8,15]]},"reference":[{"key":"2023081512543609500_c1","doi-asserted-by":"publisher","first-page":"727","DOI":"10.1097\/MAO.0b013e3180dca1e5","article-title":"Evaluation of middle ear function in young children: Clinical guidelines for the use of 226- and 1,000-Hz tympanometry","volume":"28","year":"2007","journal-title":"Otol.
