Data were statistically analyzed for effects of frequency, ear, and gender. <jats:bold>Results<\/jats:bold>\u2003Normative WBA<jats:sub>TPP<\/jats:sub> and WBA<jats:sub>0<\/jats:sub> data obtained from healthy neonates are presented. There was no significant difference between WBA<jats:sub>TPP<\/jats:sub> and WBA<jats:sub>0<\/jats:sub>\n at all frequencies. Both WBA<jats:sub>TPP<\/jats:sub> and WBA<jats:sub>0<\/jats:sub> demonstrated a multipeaked pattern with maxima of 0.80 and 0.72 at 1.25 to 1.5 and 6\u2009kHz, respectively, and two minima of 0.45 and 0.49 at 0.4 to 0.5 and 4\u2009kHz, respectively. The effects of ear and gender were not\n significant for both WBA measures. <jats:bold>Conclusion<\/jats:bold>\u2003Pressurized WBA<jats:sub>TPP<\/jats:sub> and WBA<jats:sub>0<\/jats:sub> data were provided for healthy Caucasian neonates. They will be useful for the assessment of middle ear function and assist in differentiating between conductive and sensorineural\n hearing losses in neonates.<\/jats:p>","DOI":"10.1055\/a-1925-7830","type":"journal-article","created":{"date-parts":[[2022,8,17]],"date-time":"2022-08-17T23:27:32Z","timestamp":1660778852000},"page":"381-389","source":"Crossref","is-referenced-by-count":2,"title":["Wideband
