Intelligibility Of Spondees Via Bone Conduction At Elevated Presentation Levels, Pamela S. Ritchie

Dissertations and Theses

Speech reception threshold testing by bone conduction is very useful in diagnostic audiometry. However, there are little data regarding the CID W-1 spondee word lists used with the Radioear B-71 and B-72 and Pracitronic KH 70 bone conduction vibrators at higher presentation levels for testing hearing impaired clients. Data are needed in order that results of speech reception thresholds using the CID W-1 word lists via these three bone conduction vibrators at higher intensity levels can be used confidently in the clinic. More data are available for speech reception thresholds using the CID W-1 word lists via earphones.

Speech Reception Via Bone Conduction, Sherry G. Morris

Dissertations and Theses

The purpose of this investigation was to determine if the performance-intensity function for spondees delivered via bone conduction (using the Radioear E-72 and Pracitronic KH-70) differed from the performance-intensity function for air conduction (using TDH-39 earphones). A secondary consideration addressed in this study was the comparison of the discrimination scores using the three transducers. Performance-intensity functions for spondee thresholds were calculated on 12 normal hearing subjects using two bone conduction vibrators, the Radioear B-72 and Pracitronic KH-70, and TDH-39 earphones. Results indicated that there was no significant difference between the performance-intensity function of speech via bone conduction as compared to …

The Clinical Application And Practical Limitations Of Bone Conducted Speech, Terry Scott Cochrane

Dissertations and Theses

The purpose of this study was to investigate the effects of increased intensity on the bone conducted speech discrimination ability of normal listeners utilizing standard audiological equipment. The NU-6 word lists were utilized to test the bone conducted speech discrimination skills of ten normal hearing subjects, 21 to 30 years of age, on standard clinical equipment. Both the hearing levels (dB HL) and the sensation levels (dB SL) of the test administration were considered. In general, it was recommended that 100 dB Hl is the most appropriate dial setting for the administration of bone conducted speech discrimination tests even though …
