Harmonic complexes created with negative Schroeder phases (component phases decreasing with increasing frequency) produce more masking than those with positive Schroeder phases (increasing phase) in humans, but not in birds. The masking differences in humans have been attributed to interactions between the masker phase spectrum and the phase characteristic of the basilar membrane. In birds, the similarity in masking by positive and negative Schroeder maskers, and reduced masking by cosine-phase maskers (constant phase), suggests a phase characteristic that does not change much along the basilar papilla. To evaluate this possibility, the rate of phase change across masker bandwidth was varied by systematically altering the Schroeder algorithm. Humans and three species of birds detected tones added in phase to a single component of a harmonic complex. As observed in earlier studies, the minimum amount of masking in humans occurred for positive phase gradients. However, minimum masking in birds occurred for a shallow negative phase gradient. These results suggest a cochlear delay in birds that is reduced compared to that found in humans, probably related to the shorter avian basilar epithelia.<\/jats:p>","DOI":"10.1121\/1.2151816","type":"journal-article","created":{"date-parts":[[2006,2,2]],"date-time":"2006-02-02T20:35:39Z","timestamp":1138912539000},"page":"1251-1259","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":11,"title":["Phase effects in masking by harmonic complexes in birds"],"prefix":"10.1121","volume":"119","author":[{"given":"Amanda M.","family":"Lauer","sequence":"first","affiliation":[{"name":"University of Maryland Department of Psychology, , College Park, Maryland 20742 and Center for the Comparative and Evolutionary Biology of Hearing, , College Park, Maryland 20742"},{"name":"University of Maryland Department of Psychology, , College Park, Maryland 20742 and Center for the Comparative and Evolutionary Biology of Hearing, , College Park, Maryland 20742"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert J.","family":"Dooling","sequence":"additional","affiliation":[{"name":"University of Maryland Department of Psychology, , College Park, Maryland 20742 and Center for the Comparative and Evolutionary Biology of Hearing, , College Park, Maryland 20742"},{"name":"University of Maryland Department of Psychology, , College Park, Maryland 20742 and Center for the Comparative and Evolutionary Biology of Hearing, , College Park, Maryland 20742"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marjorie R.","family":"Leek","sequence":"additional","affiliation":[{"name":"Walter Reed Army Medical Center, Washington Army Audiology and Speech Center, , DC 20307-5001 and Center for the Comparative and Evolutionary Biology of Hearing, , College Park, Maryland 20742"},{"name":"University of Maryland Army Audiology and Speech Center, , DC 20307-5001 and Center for the Comparative and Evolutionary Biology of Hearing, , College Park, Maryland 20742"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer J.","family":"Lentz","sequence":"additional","affiliation":[{"name":"Indiana University Department of Speech and Hearing Sciences, , Bloomington, Indiana 47405"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","reference":[{"key":"2023072723090820300_c1","doi-asserted-by":"publisher","first-page":"3636","DOI":"10.1121\/1.418324","article-title":"Excitation produced by Schroeder-phase complexes: Evidence for fast-acting compression in the auditory system","volume":"101","year":"1997","journal-title":"J.
