To check that the CS stimuli used did activate the efferent system, distortion product otoacoustic emissions (DPOAEs) were also measured in the absence and presence of narrowband and broadband CS. The CS had no consistent effect on the masker level at the tips of the PTCs. A broadband pink noise CS consistently reduced the masker level required for threshold on both the low- and high-frequency sides of the PTCs for the 2000-Hz signal frequency. However, there were no consistent effects of the CS for any other case. The broadband pink noise CS had a greater effect in reducing DPOAE levels than the narrowband CS. The results provide psychophysical evidence supporting the idea that the efferent system is activated more effectively by a broadband than by a narrowband CS, at least for a signal frequency of 2000 Hz.<\/jats:p>","DOI":"10.1121\/1.4871358","type":"journal-article","created":{"date-parts":[[2014,5,10]],"date-time":"2014-05-10T00:31:53Z","timestamp":1399681913000},"page":"2931-2941","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":17,"title":["Effect of broadband and narrowband contralateral noise on psychophysical tuning curves and otoacoustic emissions"],"prefix":"10.1121","volume":"135","author":[{"given":"Andrzej","family":"Wicher","sequence":"first","affiliation":[{"name":"Institute of Acoustics, Faculty of Physics, Adam Mickiewicz University , 85 Umultowska, 61-614 Poznan, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian C.
