Congenital amusia is a lifelong disorder of musical processing for which no effective treatments have been found. The present study aimed to treat amusics’ impairments in pitch direction identification through auditory training. Prior to training, twenty Chinese-speaking amusics and 20 matched controls were tested on the Montreal Battery of Evaluation of Amusia (MBEA) and two psychophysical pitch threshold tasks for identification of pitch direction in speech and music. Subsequently, ten of the twenty amusics undertook 10 sessions of adaptive-tracking pitch direction training, while the remaining 10 received no training. Post training, all amusics were retested on the pitch threshold tasks and on the three pitch-based MBEA subtests. Trained amusics demonstrated significantly improved thresholds for pitch direction identification in both speech and music, to the level of non-amusic control participants, although no significant difference was observed between trained and untrained amusics in the MBEA subtests. This provides the first clear positive evidence for improvement in pitch direction processing through auditory training in amusia. Further training studies are required to target different deficit areas in congenital amusia, so as to reveal which aspects of improvement will be most beneficial to the normal functioning of musical processing.

Abstract Background The objective of this study was to evaluate the effect of “Spatially separated speech in noise” auditory training on the ability of speech perception in noise among bimodal fitting users. The assumption was that the rehabilitation can enhance spatial hearing and hence speech in noise perception. This study was an interventional study, with a pre/post-design. Speech recognition ability was assessed with the specific tests. After performing the rehabilitation stages in the intervention group, the speech tests were again implemented, and by comparing the pre- and post-intervention data, the effect of auditory training on the speech abilities was assessed. Twenty-four children of 8–12 years who had undergone cochlear implantation and continuously used bimodal fitting were investigated in two groups of control and intervention. Results The results showed a significant difference between the groups in different speech tests after the intervention, which indicated that the intervention group have improved more than the control group. Conclusion It can be concluded that “Spatially separated speech in noise” auditory training can improve the speech perception in noise in bimodal fitting users. In general, this rehabilitation method is useful for enhancing the speech in noise perception ability.

Important Evidence

TO WHAT EXTENT DO MUSIC and language share neural mechanisms for processing pitch patterns? Musical tone-deafness (amusia) provides important evidence on this question. Amusics have problems with musical melody perception, yet early work suggested that they had no problems with the perception of speech intonation (Ayotte, Peretz, & Hyde, 2002). However, here we show that about 30% of amusics from independent studies (British and French-Canadian) have difficulty discriminating a statement from a question on the basis of a final pitch fall or rise. This suggests that pitch direction perception deficits in amusia (known from previous psychophysical work) can extend to speech. For British amusics, the direction deficit is related to the rate of change of the final pitch glide in statements/ questions, with increased discrimination difficulty when rates are relatively slow. These findings suggest that amusia provides a useful window on the neural relations between melodic processing in language and music.

Introduction Computerized auditory training (CAT) has been building a good reputation in the stimulation of auditory abilities in cases of auditory processing disorder (APD). Objective To measure the effects of CAT in students with APD, with typical or atypical phonological acquisition, through electrophysiological and subjective measures, correlating them pre- and post-therapy. Methods The sample for this study includes14 children with APD, subdivided into children with APD and typical phonological acquisition (G1), and children with APD and atypical phonological acquisition (G2). Phonological evaluation of children (PEC), long latency auditory evoked potential (LLAEP) and scale of auditory behaviors (SAB) were conducted to help with the composition of the groups and with the therapeutic intervention. The therapeutic intervention was performed using the software Escuta Ativa (CTS Informática, Pato Branco, Brazil) in 12 sessions of 30 minutes, twice a week. For data analysis, the appropriate statistical tests were used. Results A decrease in the latency of negative wave N2 and the positive wave P3 in the left ear in G1, and a decrease of P2 in the right ear in G2 were observed. In the analysis comparing the pre- and post-CAT groups, there was a significant difference in P1 latency in the left ear and P2 latency in the right ear, pre-intervention. Furthermore, eight children had an absence of the P3 wave, pre-CAT, but after the intervention, all of them presented the P3 wave. There were changes in the SAB score pre- and post-CAT in both groups. The presence of correlation between the scale and some LLAEP components was observed. Conclusion The CAT produced an electrophysiological modification, which became evident in the effects of the effects of neural plasticity after CAT. The SAB proved to be useful in measuring the therapeutic effects of the intervention. Moreover, there were behavioral changes in the SAB (higher scores) and correlation with LLAEP.

Abstract Background: The ovary is the core reproductive organ of a woman and is of great significance for maintaining normal functioning of the reproductive system and the stability of the endocrine system. With an increase in age, the ovaries begin to age, and ovarian ageing will cause a decline in fertility. Methods: Ageing C57 mice were used to explore the mechanism by which mouse umbilical cord mesenchymal stem cells (mUCMSCs) promote the antioxidant repair of granulocytes (mGCs). The ovarian volume in C57 mice, which were routinely reared to 18 months, decreased, and the follicles at all levels disappeared. All statistical analyses were performed using SPSS 21.0 statistical software. P <0.05 was considered to indicate a significant difference. Results: After mUCMSC transplantation, the mouse ovaries increased in size, follicles at various levels were seen in the cortex, and sinus follicle counts increased, indicating that mUCMSCs have a curative effect on ovarian ageing. Conclusions: mUCMSCs downregulated the expression of apoptosis-related genes (Bax, Caspase-3), upregulated the expression of SOD2 and the peroxidase gene PRDX IV, and reduced the granulocyte apoptosis rate and ROS level. Co-cultivation with mUCMSCs can increase antioxidative stress in mGCs and reduce mGC apoptosis.

Purpose Auditory training is known to improve the speech-perception-in-noise (SPIN) skills in children with auditory processing disorders (APDs); however, conventional non–computer-based trainings are dreary and nonmotivating. This study intended to develop a computer-based noise desensitization training module in Indian English and test the efficacy of the same in children with APD having SPIN deficits. There are no such modules available at present to be used in Indian children. Method The module incorporated words-in-noise training, with monosyllables and trisyllables as target words in the presence of speech-shaped noise as well as multitalker babble at different signal-to-noise ratios ranging from +20 to −4 dB SNR. The study included 20 children with SPIN deficits diagnosed with APD and who were recruited randomly to the experimental group who received the training ( n = 10; M age = 11.1 years) and to the control group who did not receive any training ( n = 10; M age = 11.4 years). The outcome measures included behavioral measures and electrophysiological measures (auditory long latency responses for speech in quiet and noise). Results Compared to children in the control group, children in the experimental group exhibited improvements in the SPIN scores as well as temporal processing measures after training. Dichotic consonant–vowel tests and auditory memory and sequencing tests did not yield significant improvement post training. Also, auditory long latency responses in quiet and noise revealed significant reduction in the amplitudes after training. No significant difference was noted in the latencies of auditory long latency responses post training. Control group participants did not show any significant difference in any of the measures between the initial and follow-up evaluations. Conclusions The developed training module was successful in fetching improvements in behavioral and electrophysiological measures. It would be a great addition to the evidence-based rehabilitation support inventory for children with SPIN deficits in India. Supplemental Material https://doi.org/10.23641/asha.14551041

Background and Aim: Decoding deficit is the most common central auditory processing disorder (CAPD). Given the benefits of computer-based auditory training programs for treatment of central disorders and the lack of such programs in Persian language, this study aimed to develop a computer-based auditory training program for decoding skill. We also evaluated this program in 8 to12 year old children with CAPD.Methods: The first stage of research was to develop a computer-based auditory training program. This program consists of three levels of phonological discrimination, syllable discrimination, and word discrimination. The second stage was to determine the content and face validity of the program. The third stage was to assess the program effect on five children with decoding deficit. The research method was interventional and had a pretest and post-test design with another five children as control group. The staggered spondaic word, phonemic synthesis (PS) and speech in noise tests was used to assess the children performance before and after training.Results: Mean scores of staggered spondaic word (SSW) and PS tests of the experimental group were significantly difference before and after the auditory training (p<0.05) as compared to control group. However, there was no significant difference with regard to the speech-in-noise test results (p>0.05).Conclusion: This computer-based auditory training program can be considered as a preliminary tool for the rehabilitation and treatment of decoding deficits in children with CAPD.

Objectives: In a clinical setting, a ‘trained ear’ is the essentials for speech–language pathologists (SLPs) because most SLPs rely on the auditory - perceptual method during assessment and treatment for speech difficulties. However, transcribing distortion errors using only auditory-perceptual judgement is a difficult task. This study investigated the auditory– perceptual ability in terms of distortion errors for pre and present SLPs.Methods: Sixty pre and present SLPs completed a survey, then performed a perceptual judgement task which was manufactured by electropalatography (EPG). The task consisted of 30 questions, including distorted (dentalized, palatalized, lateralized) and normal speech samples of Korean fricative /s/ with different types of vowels (/ɑ/, /u/) and lengths (1-syllabled, 2- syllabled, sentence).Results: There was no significant difference in the distortion task among three groups. All participants had the highest score in “dentalization”, the lowest in “lateralization”, and all distortion types were perceived better in the /u/ context than /ɑ/. Also, SLPs tended to judge “lateralization” errors as “normal articulation” and many of the participants perceived “palatalization” as “lateralization”.Conclusion: The results of this study indicated that active auditory training for SLPs is necessary to improve auditory perceptual ability, and suggests that EPG could be a useful instrument for the auditory training program.

PurposeThe aims of this study were to determine if a remotely delivered, Internet-based auditory training (AT) program improved speech-in-noise understanding and if the number of hours spent engaged in the program influenced postintervention speech-in-noise understanding.MethodTwenty-nine first-time hearing aid users were randomized into an AT group (hearing aids + 3 week remotely delivered, Internet-based auditory training program) or a control group (hearing aids alone). The Hearing in Noise Test (Nilsson, Soli, & Sullivan, 1994) and the Words-in-Noise test (Wilson, 2003) were administered to both groups at baseline + 1 week and immediately at the completion of the 3 weeks of auditory training.ResultsSpeech-in-noise understanding improved for both groups at the completion of the study; however, there was not a statistically significant difference in postintervention improvement between the AT and control groups. Although the number of hours the participants engaged in the AT program was far fewer than prescribed, time on task influenced the postintervention Words-in-Noise but not Hearing in Noise Test scores.ConclusionAlthough remotely delivered, Internet-based AT programs represent an attractive alternative to resource-intensive, clinic-based interventions, their demonstrated efficacy continues to remain a challenge due in part to issues associated with compliance.
