Evaluation of babies with hearing aids using visual reinforced ınfant speech discrimination method: A case series Speech perception measurements are an important part of the audiology test battery. It is important to investigate hearing loss in the early period and to evaluate the auditory pathway in terms of speech perception for appropriate amplification. Due to the level of language development in infants, it is not possible to objectively evaluate speech perception skills with the speech test battery used in adults. It is necessary to use a test battery that gives objective results for the measurement of speech perception in infants. Visual Reinforcement Infant Speech Discrimination (VRISD) method is the most commonly used test technique to evaluate speech discrimination skills in infants. The aim of this study is to evaluate the speech discrimination skills of 3 babies aged 6-18 months, who are hearing aid users, with the VRISD test method. In the VRISD test protocol used in this study, test stimuli were created by matching /a/ with /i/ and /ba/ with /da/ speech stimuli. These stimulus pairs are arranged as one target sound and the other background sound, and they are presented at 70 dB via loudspeaker by creating a repeating sound sequence. Animated video that attracts the attention of the baby was used as visual reinforcement. Speech discrimination skills of 3 babies with bilateral hearing aids were evaluated with the VRISD test, and the results of the cases are presented. As a result of the study, speech discrimination skills of babies with hearing aids will be evaluated with the VRISD test method. These results contribute to habilitation and amplification programming. Keywords: Hearing aid, speech perception, pediatric audiology

The Impact

Background: Speech perception measures have long been considered an integral piece of the audiological assessment battery. Currently, a prelinguistic, standardized measure of speech perception is missing in the clinical assessment battery for infants and young toddlers. Such a measure would allow systematic assessment of speech perception abilities of infants as well as the potential to investigate the impact early identification of hearing loss and early fitting of amplification have on the auditory pathways. Purpose: To investigate the impact of sensation level (SL) on the ability of infants with normal hearing (NH) to discriminate /a-i/ and /ba-da/ and to determine if performance on the two contrasts are significantly different in predicting the discrimination criterion. Research Design: The design was based on a survival analysis model for event occurrence and a repeated measures logistic model for binary outcomes. The outcome for survival analysis was the minimum SL for criterion and the outcome for the logistic regression model was the presence/absence of achieving the criterion. Criterion achievement was designated when an infant’s proportion correct score was >0.75 on the discrimination performance task. Study Sample: Twenty-two infants with NH sensitivity participated in this study. There were 9 males and 13 females, aged 6–14 mo. Data Collection and Analysis: Testing took place over two to three sessions. The first session consisted of a hearing test, threshold assessment of the two speech sounds (/a/ and /i/), and if time and attention allowed, visual reinforcement infant speech discrimination (VRISD). The second session consisted of VRISD assessment for the two test contrasts (/a-i/ and /ba-da/). The presentation level started at 50 dBA. If the infant was unable to successfully achieve criterion (>0.75) at 50 dBA, the presentation level was increased to 70 dBA followed by 60 dBA. Data examination included an event analysis, which provided the probability of criterion distribution across SL. The second stage of the analysis was a repeated measures logistic regression where SL and contrast were used to predict the likelihood of speech discrimination criterion. Results: Infants were able to reach criterion for the /a-i/ contrast at statistically lower SLs when compared to /ba-da/. There were six infants who never reached criterion for /ba-da/ and one never reached criterion for /a-i/. The conditional probability of not reaching criterion by 70 dB SL was 0% for /a-i/ and 21% for /ba-da/. The predictive logistic regression model showed that children were more likely to discriminate the /a-i/ even when controlling for SL. Conclusions: Nearly all normal-hearing infants can demonstrate discrimination criterion of a vowel contrast at 60 dB SL, while a level of ≥70 dB SL may be needed to allow all infants to demonstrate discrimination criterion of a difficult consonant contrast.

AbstractSloping hearing loss imposes limits on audibility for high-frequency sounds in many hearing aid users. Signal processing algorithms that shift high-frequency sounds to lower frequencies have been introduced in hearing aids to address this challenge by improving audibility of high-frequency sounds.This study examined speech perception performance, listening effort, and subjective sound quality ratings with conventional hearing aid processing and a new frequency-lowering signal processing strategy called frequency composition (FC) in adults and children.Participants wore the study hearing aids in two signal processing conditions (conventional processing versus FC) at an initial laboratory visit and subsequently at home during two approximately six-week long trials, with the order of conditions counterbalanced across individuals in a double-blind paradigm.Children (N = 12, 7 females, mean age in years = 12.0, SD = 3.0) and adults (N = 12, 6 females, mean age in years = 56.2, SD = 17.6) with bilateral sensorineural hearing loss who were full-time hearing aid users.Individual performance with each type of processing was assessed using speech perception tasks, a measure of listening effort, and subjective sound quality surveys at an initial visit. At the conclusion of each subsequent at-home trial, participants were retested in the laboratory. Linear mixed effects analyses were completed for each outcome measure with signal processing condition, age group, visit (prehome versus posthome trial), and measures of aided audibility as predictors.Overall, there were few significant differences in speech perception, listening effort, or subjective sound quality between FC and conventional processing, effects of listener age, or longitudinal changes in performance. Listeners preferred FC to conventional processing on one of six subjective sound quality metrics. Better speech perception performance was consistently related to higher aided audibility.These results indicate that when high-frequency speech sounds are made audible with conventional processing, speech recognition ability and listening effort are similar between conventional processing and FC. Despite the lack of benefit to speech perception, some listeners still preferred FC, suggesting that qualitative measures should be considered when evaluating candidacy for this signal processing strategy.

Noise Management

Background: Before advanced noise-management features can be recommended for use in children with hearing loss, evidence regarding their ability to use these features to optimize speech perception is necessary. Purpose: The purpose of this study was to examine the relation between children's preference for, and performance with, four combinations of noise-management features in noisy listening environments. Research Design: Children with hearing loss were asked to repeat short sentences presented in steady-state noise or in multitalker babble while wearing ear-level hearing aids. The aids were programmed with four memories having an orthogonal arrangement of two noise-management features. The children were also asked to indicate the hearing aid memory that they preferred in each of the listening conditions both initially and after a short period of use. Study Sample: Fifteen children between the ages of 8 and 12 yr with moderate hearing losses, bilaterally. Results: The children's preference for noise management aligned well with their performance for at least three of the four listening conditions. The configuration of noise-management features had little effect on speech perception with the exception of reduced performance for speech originating from behind the child while in a directional hearing aid setting. Additionally, the children's preference appeared to be governed by listening comfort, even under conditions for which a benefit was not expected such as the use of digital noise reduction in the multitalker babble conditions. Conclusions: The results serve as evidence in support of the use of noise-management features in grade-school children as young as 8 yr of age.

Test Result

The SIR test was created for use in hearing aid comparisons. The test protocol obtains listener judgments of the intelligibility of connected speech passages. This study was conducted to evaluate the effectiveness of the SIR test in differentiating among hearing aids Specific research questions were (a) Is the sensitivity of the SIR test sufficient for differentiating among very similar and slightly dissimilar hearing aids? (b) Does the SIR test result In reliable heanng aid rankings? and (c) What are the effects of using shortened connected speech passages? Ten listeners with hearing impairments rated the intelligibility of both full-length and shortened SIR test passages while wearing each of four individually selected hearing aids representing three different frequency/gain prescriptions. Results suggested that the SIR test is capable of differentiating among slightly dissimilar hearing aids and that hearing aid rankings resulting from speech Intelligibility ratings were reliable. The decision to use full-length or shortened SIR test passages depends on the outcome the user wishes to maximize Under the conditions used n this study, maximum sensitivity was achieved with ratings from five shortened passages, whereas maximum reliability was obtained with three full-length passages.

ABSTRACTThe possibility that early linguistic experience affects infant speech perception was investigated in a cross-linguistic study with naturally produced speech stimuli. Using the Visually Reinforced Infant Speech Discrimination paradigm, three contrasts were presented to Spanish-and English-learning infants 6–8 months of age. Both groups of infants showed statistically significant discrimination of two contrasts, English and Czech. Only the Spanish-learning infants provided evidence of discrimination of the Spanish contrast. The groups discriminated the English contrast at similarly high levels, but the Spanish-learning infants showed significantly higher performance than the English on both the Spanish and the Czech contrast. The results indicate that early experience does affect early discrimination, and further (since the stimuli were natural) that the effect may be of practical consequence in language learning.

Background: Auditory neuropathy spectrum disorder (ANSD) is a form of sensorineural hearing loss, causing severe deficits in speech perception. The perceptual problems of individuals with ANSD were attributed to their temporal processing impairment rather than to reduced audibility. This rendered their rehabilitation difficult using hearing aids. Although hearing aids can restore audibility, compression circuits in a hearing aid might distort the temporal modulations of speech, causing poor aided performance. Therefore, hearing aid settings that preserve the temporal modulations of speech might be an effective way to improve speech perception in ANSD. Purpose: The purpose of the study was to investigate the perception of hearing aid–processed speech in individuals with late-onset ANSD. Research Design: A repeated measures design was used to study the effect of various compression time settings on speech perception and perceived quality. Study Sample: Seventeen individuals with late-onset ANSD within the age range of 20–35 yr participated in the study. Data Collection and Analysis: The word recognition scores (WRSs) and quality judgment of phonemically balanced words, processed using four different compression settings of a hearing aid (slow, medium, fast, and linear), were evaluated. The modulation spectra of hearing aid–processed stimuli were estimated to probe the effect of amplification on the temporal envelope of speech. Repeated measures analysis of variance and post hoc Bonferroni’s pairwise comparisons were used to analyze the word recognition performance and quality judgment. Results: The comparison between unprocessed and all four hearing aid–processed stimuli showed significantly higher perception using the former stimuli. Even though perception of words processed using slow compression time settings of the hearing aids were significantly higher than the fast one, their difference was only 4%. In addition, there were no significant differences in perception between any other hearing aid–processed stimuli. Analysis of the temporal envelope of hearing aid–processed stimuli revealed minimal changes in the temporal envelope across the four hearing aid settings. In terms of quality, the highest number of individuals preferred stimuli processed using slow compression time settings. Individuals who preferred medium ones followed this. However, none of the individuals preferred fast compression time settings. Analysis of quality judgment showed that slow, medium, and linear settings presented significantly higher preference scores than the fast compression setting. Conclusions: Individuals with ANSD showed no marked difference in perception of speech that was processed using the four different hearing aid settings. However, significantly higher preference, in terms of quality, was found for stimuli processed using slow, medium, and linear settings over the fast one. Therefore, whenever hearing aids are recommended for ANSD, those having slow compression time settings or linear amplification may be chosen over the fast (syllabic compression) one. In addition, WRSs obtained using hearing aid–processed stimuli were remarkably poorer than unprocessed stimuli. This shows that processing of speech through hearing aids might have caused a large reduction of performance in individuals with ANSD. However, further evaluation is needed using individually programmed hearing aids rather than hearing aid–processed stimuli.

Introduction Current literature does not provide strong evidence that remote programming of hearing aids is effective, despite its increasing use by audiologists. We tested speech perception outcomes, real-ear insertion gain, and changes in self-perceived hearing impairment after face-to-face and remote programming of hearing aids in a randomized multicentre, single-blind crossover study. Methods Adult experienced hearing aid users were enrolled during routine follow-up visits to audiology clinics. Hearing aids were programmed both face to face and remotely, then participants randomly received either the face-to-face or remote settings in a blinded manner and were evaluated 5 weeks later. Participants then received the other settings and were evaluated 5 weeks later. Results Data from 52 out of 60 participants were analysed. We found excellent concordance in performance of hearing aids programmed face to face and remotely for speech understanding in quiet (phonetically balanced kindergarten test – intraclass correlation coefficient of 0.92 (95% confidence interval: 0.87–0.95)), and good concordance in performance for speech understanding in noise (phonetically balanced kindergarten +5 dB signal-to-noise ratio – intraclass correlation coefficient of 0.71 (95% confidence interval: 0.55–0.82)). Face-to-face and remote programming took 10 minutes (±2.9) and 10 minutes (±2.8), respectively. Real-ear insertion gains were highly correlated for input sound at 50, 65 and 80 dB sound pressure levels. The programming type did not affect the abbreviated profile of hearing aid questionnaire scores. Conclusions In experienced hearing aid users, face-to-face and remote programming of hearing aids give similar results in terms of speech perception, with no increase in the time spent on patients’ care and no difference in self-reported hearing benefit.

Purpose The study was designed primarily to determine if the use of hearing aids (HAs) in individuals with hearing impairment in China would affect their speechreading performance. Method Sixty-seven young adults with hearing impairment with HAs and 78 young adults with hearing impairment without HAs completed newly developed Chinese speechreading tests targeting 3 linguistic levels (i.e., words, phrases, and sentences). Results Groups with HAs were more accurate at speechreading than groups without HA across the 3 linguistic levels. For both groups, speechreading accuracy was higher for phrases than words and sentences, and speechreading speed was slower for sentences than words and phrases. Furthermore, there was a positive correlation between years of HA use and the accuracy of speechreading performance; longer HA use was associated with more accurate speechreading. Conclusions Young HA users in China have enhanced speechreading performance over their peers with hearing impairment who are not HA users. This result argues against the perceptual dependence hypothesis that suggests greater dependence on visual information leads to improvement in visual speech perception.
