Freyaldenhoven, Melinda C.; Plyler, Patrick N.; Thelin, James W.; Hedrick, Mark S. – Journal of Speech, Language, and Hearing Research, 2007
Purpose: To compare the effects of speech presentation level on acceptance of noise in listeners with normal and impaired hearing. Method: Participants were listeners with normal (n = 24) and impaired (n = 46) hearing who were matched for conventional acceptable noise level (ANL). ANL was then measured at 8 fixed speech presentation levels (40,…

Hedrick, Mark S.; Younger, Mary Sue – Journal of Speech, Language, and Hearing Research, 2007
Purpose: To determine if listeners with normal hearing and listeners with sensorineural hearing loss give different perceptual weightings to cues for stop consonant place of articulation in noise versus reverberation listening conditions. Method: Nine listeners with normal hearing (23-28 years of age) and 10 listeners with sensorineural hearing…

Tampas, Joanna W.; Harkrider, Ashley W.; Hedrick, Mark S. – Journal of Speech, Language, and Hearing Research, 2005
Auditory event-related potentials (mismatch negativity and P300) and behavioral discrimination were measured to synthetically generated consonant-vowel (CV) speech and nonspeech contrasts in 10 young adults with normal auditory systems. Previous research has demonstrated that behavioral and P300 responses reflect a phonetic, categorical level of…
