Audiological evaluation of nonspeaking, physically challenged populations.

When assessing the hearing of physically challenged nonspeaking individuals, examiners generally restrict the assessment to pure tone testing which limits the diagnostic value of the evaluation. This study recommends adapting the standard speech audiometry procedures by utilizing an eye gaze response mode. Results indicate that an eye gaze technique can be used effectively in a clinical setting. Strategies and techniques are proposed for adapting a variety of speech audiometric procedures.

Improving listening in the elementary grades.

A single stratagem was taught to 36 students: 12 each in the second grade, the fourth grade, and the sixth grade, to improve their listening skills. The basic six stratagem taught the children how to ask who, what, when, where, why, and how questions. The children were seen three times a week in groups of six. The results of a pre - post test showed statistically significant improvement for the children in the listening program. The second-grade group showed an average improvement of 3.92 correct answers, a 23% improvement. The fourth-grade group showed an average improvement of 5.75 correct answers, a 23% improvement. The sixth-grade group showed an average improvement of 4.55 correct answers, a 12% improvement. Their classmates in the fourth and sixth grades, who also took the pre - post test, show no improvement in their pre - post test scores. The second-grade classroom children showed a significant improvement of 1.55 correct answers, which was a 9% improvement. The listening skills of children in the elementary grades can be improved through a direct teaching of a specific stratagem in a small group setting.

A system for reporting tympanometric results.

Available electroacoustic middle-ear measurement instruments report information concerning middle-ear function in at least six different terms. These terms are used to report middle-ear function: impedance, compliance, admittance, susceptance, conductance, and volume. A standard system for the clinical expression of middle-ear measurements, regardless of the particular measurement unit used, is proposed.

Comparison of two methods to predict cochlear pathology from Békésy tracings.

Two different methods for classifying cochlear pathology were applied to 62 BEKESY AUDIOGRAMS obtained from cochlear pathology subjects to determine which method was the better indicator of cochlear pathology. The two methods compared were: (1) Jerger's type II, which is based upon the difference (D) between the client's threshold for the interrupted-tone tracing and the threshold for the continuous-tone tracing; and (2) Bilger's Wc, which is the swing width of the continuous tone tracing for 4,000 Hz. Results indicated that D classified 62% of the audiograms (39) correctly, and Wc classified 52% of the audiograms (32) correctly. Both measures jointly classified 37% of the audiograms (23) correctly and jointly missed 23% of the audiograms (14). Statistical analysis showed no difference between the two methods in classifying cochlear pathology.

Typing of Békésy audiograms.

Jerger's method for classifying BEKESY AUDIOGRAMS is the most widely acccepted clinical classification system. The audiologist types the BEKESY audiogram based upon visual inspection of the relation between the continuous- and interrupted-tone tracings. To determine the extent of agreement among audiogram type, four expert judges using a forced-choice, blind procedure, independently typed 170 audiograms. Contingency coefficients were between 0.89 and 0.90 for the six sets of paired judges. Contingency coefficients between each judge and a numerical criterion classification system ranged from 0.86 to 0.94 representing the validity of the visual method. The visual method is a valid procedure for typing BEKESY AUDIOGRAMS.
