Changes In Sound Pressure And Fundamental Frequency Contours Following Changes In Hearing Status, Harlan Lane, Jane Wozniak, Melanie Matthies, Mario Svirsky, Joseph Perkell, Michael O'Connell, Joyce Manzella
Harlan Lane
Sound-pressure level (SPL) and fundamental frequency (F0) contours were obtained from four postlingually deafened adults who received cochlear implants and from a subject with Neurofibromatosis-2 (NF2) who had her hearing severely reduced following surgery to remove an auditory-nerve tumor and to implant an auditory brainstem implant. SPL and F0 contours for each phrase in passages read before and after changes in hearing were averaged over repeated readings and then normalized with respect to the highest SPL or F0 value in the contour. The regularity of each average contour was measured by calculating differences between successive syllable means and averaging the …
