Sentence Intelligibility

A sentence intelligibility test was used to evaluate listener performance with three hearing aids differing substantially in physical characteristics. Thirty six hard-of-hearing listeners, representing various types and degrees of hearing loss, were tested. Results showed that, although the sentence intelligibility test reflected meaningful average differences among the aids, the rank ordering of aids was essentially equivalent for all listeners.

Purpose Pitch reception poses challenges for individuals with cochlear implants (CIs), and adding a hearing aid (HA) in the nonimplanted ear is potentially beneficial. The current study used fine-scale synthetic speech stimuli to investigate the bimodal benefit for lexical tone categorization in Mandarin-speaking kindergarteners using a CI and an HA in opposite ears. Method The data were collected from 16 participants who were required to complete two classical tasks for speech categorical perception (CP) with CI + HA device condition and CI alone condition. Linear mixed-effects models were constructed to evaluate the identification and discrimination scores across different device conditions. Results The bimodal kindergarteners showed CP for the continuum varying from Mandarin Tone 1 and Tone 2. Moreover, the additional acoustic information from the contralateral HA contributes to improved lexical tone categorization, with a steeper slope, a higher discrimination score of between-category stimuli pair, and an improved peakedness score (i.e., an increased benefit magnitude for discriminations of between-category over within-category pairs) for the CI + HA condition than the CI alone condition. The bimodal kindergarteners with better residual hearing thresholds at 250 Hz level in the nonimplanted ear could perceive lexical tones more categorically. Conclusion The enhanced CP results with bimodal listening provide clear evidence for the clinical practice to fit a contralateral HA in the nonimplanted ear in kindergarteners with unilateral CIs with direct benefits from the low-frequency acoustic hearing.

Sentence Intelligibility

Purpose This study examined the effects of lexical tone contour on the intelligibility of Mandarin sentences in quiet and in noise. Method A text-to-speech synthesis engine was used to synthesize Mandarin sentences with each word carrying the original lexical tone, flat tone, or a tone randomly selected from the 4 Mandarin lexical tones. The synthesized speech signals were presented to 11 normal-hearing listeners for recognition in quiet and in speech-shaped noise at 0 dB signal-to-noise ratio. Results Normal-hearing listeners nearly perfectly recognized the Mandarin sentences produced with modified tone contours in quiet; however, performance declined substantially in noise. Conclusions Consistent with previous findings to some extent, the present findings suggest that lexical tones are relatively redundant cues for Mandarin sentence intelligibility in quiet and that other cues could compensate for the distorted lexical tone contour. However, in noise, the results provide direct evidence that lexical tone contour is important for the recognition of Mandarin sentences.

Lexical Tone Recognition

Pitch perception is known to be difficult for individuals with cochlear implant (CI), and adding a hearing aid (HA) in the non-implanted ear is potentially beneficial. The current study aimed to investigate the bimodal benefit for lexical tone recognition in Mandarin-speaking preschoolers using a CI and an HA in opposite ears. The child participants were required to complete tone identification in quiet and in noise with CI + HA in comparison with CI alone. While the bimodal listeners showed confusion between Tone 2 and Tone 3 in recognition, the additional acoustic information from the contralateral HA alleviated confusion between these two tones in quiet. Moreover, significant improvement was demonstrated in the CI + HA condition over the CI alone condition in noise. The bimodal benefit for individual subjects could be predicted by the low-frequency hearing threshold of the non-implanted ear and the duration of bimodal use. The findings support the clinical practice to fit a contralateral HA in the non-implanted ear for the potential benefit in Mandarin tone recognition in CI children. The limitations call for further studies on auditory plasticity on an individual basis to gain insights on the contributing factors to the bimodal benefit or its absence.

Sentence Intelligibility

A sentence intelligibility test and three monosyllabic word intelligibility tests, recorded through three hearing aids, were presented to 36 subjects with diverse types of hearing loss. Although hearing aids were rank ordered meaningfully on the sentence intelligibility test-in inverse proportion to the harmonic distortion-performance differences were not systematically reflected in the monosyllabic word test results.

Classroom teachers were asked to list the traits they felt were characteristic of the elementary school child who wears a hearing aid. These listings were evaluated according to the desirability of the traits and were studied regarding frequency of occurrence, desirability, and educational, emotional, and social implications. The results of the groupings are discussed in terms of pre-service and in-service training.

Males And Females

Prior studies have proven the existence of the "hearing aid effect" when photographs of Caucasian males and females wearing a body aid, a post-auricular aid (behind-the-ear), or no hearing aid were judged by lay persons and professionals. This study was performed to determine if African American and Caucasian males, judged by female members of their own race, were likely to be judged in a similar manner on the basis of appearance, personality, assertiveness, and achievement. Sixty female undergraduate education majors (30 African American; 30 Caucasian) used a semantic differential scale to rate slides of preteen African American and Caucasian males, with and without hearing aids. The results of this study showed that female African American and Caucasian judges rated males of their respective races differently. The hearing aid effect was predominant among the Caucasian judges across the dimensions of appearance, personality, assertiveness, and achievement. In contrast, the African American judges only exhibited a hearing aid effect on the appearance dimension.

Twenty students between the ages of 6 and 19 years who were receiving services for students with hearing impairments in a metropolitan, inner-city school system were trained to monitor their own hearing aids. This study investigated the effect of this training on the percentage of students who wore functional hearing aids. Ten of the students received fewer than 3 hours of instruction per day in the regular education setting and generally had hearing losses in the severe to profound range. The remaining 10 students received greater than 3 hours of instruction per day in the regular education setting and had hearing losses in the moderate to severe range. The findings indicated improved hearing aid function when students were actively involved in hearing aid maintenance programs. Recommendations are made concerning hearing aid maintenance in the schools.
