Determination of appropriate compression rate for developing the Persian version of time compressed sentence test

Background and Aim: Time compressed speech test is one of the most useful monaural tests for evaluation of central auditory processing disorder. For developing the time compressed sentences test, the compression rate of the sentences must be set so that the average speech comprehension score is about 90% in normal individuals and can challenge central auditory processing system sufficiently so subjects with auditory processing disorders could be identified. Therefore, the aim of the present study was finding the appropriate compression rate for developing compressed sentences test in Persian. Method: Initially, two 10-sentence lists were prepared based on the experts’ opinion and were compressed by the amount of 60, 65, 70, 75 and 80% using Praat software. Compressed sentences were tested on twelve 18–25 year-old normal individuals and the speech comprehension score in different compression rates was compared and the compression rate in which the average score was approximately 90% was reported as an appropriate compression rate for developing time compressed sentences test in Persian. Results: 70% compression rate was able to create an average score of 95.27% (± 3.31) and 93.6% (± 7.17) in the right and left ear, respectively. Conclusion: Results showed that the compression rate of 70% was appropriate rate for developing the test in the Persian language.

Abstract Introduction Dysphonia is an oral communication disorder. The voice and hearing are interrelated aspects. Hearing is an important sensory input for monitoring the vocal pattern. The relation between hearing abilities and dysphonia represents a contribution both in scientific and in clinical terms, especially in cases in which satisfactory results are not achieved in the therapeutic process. Objective To characterize long-latency auditory evoked potential (P300) with tonal and complex stimuli, and to make a behavioral evaluation of auditory processing in adults with behavioral dysphonia. Method The sample used for the present study consisted of 20 subjects from both genders with ages ranging from 18 and 58, who were diagnosed with behavioral dysphonia. The evaluations occurred in a single 2-hour session, in which the procedures of clinical history, pure tone and speech audiometries, acoustic immittance measures, and behavioral and electrophysiological evaluations of auditory processing were performed. Results The descriptive measures of P3 latency elicited by tonal and complex stimuli showed similar results for the right and left ears, without statistically significant differences. In the qualitative analysis, the results observed were within the normality patterns for the P3 component for both tonal and complex stimuli. As for the behavioral evaluation of auditory processing, abnormal results were observed in 100% of the sample. Abnormalities were found in the auditory skills of ordering and temporal resolution and figure-background obtained from the duration pattern, random gap detection, and dichotic tests (syllables and words), respectively. Conclusion The evaluated patients presented central auditory processing disorder, evidenced by behavioral assessment.

Objective We hypothesized that if the right hemisphere auditory processing abilities can be altered in children with developmental dyslexia (DD), we can detect dysfunction using specific tests. Method We performed an analytical comparative cross-sectional study. We studied 20 right-handed children with DD and 20 healthy right-handed control subjects (CS). Children in both groups were age, gender, and school-grade matched. Focusing on the right hemisphere’s contribution, we utilized tests to measure alterations in central auditory processing (CAP), such as determination of frequency patterns; sound duration; music pitch recognition; and identification of environmental sounds. We compared results among the two groups. Results Children with DD showed lower performance than CS in all CAP subtests, including those that preferentially engaged the cerebral right hemisphere. Conclusion Our data suggests a significant contribution of the right hemisphere in alterations of CAP in children with DD. Thus, right hemisphere CAP must be considered for examination and rehabilitation of children with DD.

The Northwestern University Auditory Test Number 6 (NU-6) measure of speech discrimination was time compressed and presented to four age groups ranging from 54 to 84 years of age. Experimental stimuli were presented at sensation levels of 24, 32, and 40 dB to an equal number of right and left ears and male and female subjects. Results indicated that intelligibility decreased as a function of increasing time compression and age and decreasing sensation level. Changes in speech intelligibility associated with the aging process appear to be closely allied to changes in the temporal resolving power of the central auditory processing system.

Temporal Ordering

Abstract Background The aging process is characterized by a gradual impairment of several capacities, such as hearing, memory and communication, which implies changes at various levels and, consequently, changes in both hearing and auditory skills, of which the auditory temporal ordering is an example. Methods The sample consisted of 23 elderly individuals, aged between 70 and 96 years (average of 83.09 years) and with mild to severe type I sensorineural hearing loss. For the collection of information, the pure tone audiogram, the frequency and duration pattern tests, the verbal and non-verbal sequential memory tests were used. Results The results revealed that between age and the auditory temporal order tests there was a negative correlation (except in the duration pattern test in the left ear) and between the auditory threshold and the auditory temporal order tests there was negative correlation (except in the duration pattern test in the right ear). Conclusions It is concluded that in this sample the ability of auditory temporal ordering was influenced by aging and hearing loss, which shows that as the age of the elderly progresses and the degree of hearing loss increases the difficulties in temporal auditory processing become larger. This leads us to consider that these elderly have several difficulties in temporal auditory processing and that an intervention as auditory training may be advantageous for the elderly, as it could improve their central auditory processing and, consequently, their hearing, memory and quality of life.

Spatial hearing is critical for us not only to orient ourselves in space, but also to follow a conversation with multiple speakers involved in a complex sound environment. The hearing ability of people who suffered from severe sensorineural hearing loss can be restored by cochlear implants (CIs), however, with a large outcome variability. Yet, the causes of the CI performance variability remain incompletely understood. Despite the CI-based restoration of the peripheral auditory input, central auditory processing might still not function fully. Here we developed a multi-modal repetition suppression (MMRS) paradigm that is capable of capturing stimulus property-specific processing, in order to identify the neural correlates of spatial hearing and potential central neural indexes useful for the rehabilitation of sound localization in CI users. To this end, 17 normal hearing and 13 CI participants underwent the MMRS task while their brain activity was recorded with a 256-channel electroencephalography (EEG). The participants were required to discriminate between the probe sound location coming from a horizontal array of loudspeakers. The EEG MMRS response following the probe sound was elicited at various brain regions and at different stages of processing. Interestingly, the more similar this differential MMRS response in the right temporo-parieto-occipital (TPO) junction in CI users was to the normal hearing group, the better was the spatial hearing performance in individual CI users. Based on this finding, we suggest that the differential MMRS response at the right TPO junction could serve as a central neural index for intact or impaired sound localization abilities.

Background/Aim: Central auditory processing disorder (CAPD) might precede the onset of Alzheimer’s disease (AD). A method of evaluating CAPD is the dichotic digits test (DDT). The aim was to address this in a longitudinal setting. Methods: A total of 136 individuals were assessed with peripheral and central hearing tests at baseline and at 5-year follow-up. Results: Subjects with AD showed a significant decline in DDT scores of the right ear from baseline to follow-up. The other groups retained high DDT scores. Peripheral auditory function declined as expected according to age. Conclusions: Our study indicates that DDT performance reflects an ongoing process resulting in dementia.

Objective To contribute to the validation of AudBility, an online central auditory processing screening program, considering the tasks for age between 6 and 8 years-old, from the investigation of sensitivity and specificity, as well as to suggest a minimum central auditory processing (CAP) screening protocol in this age group. Method In the first stage of the study, 154 schoolchildren were screened. Children were aged between 6 and 8 years old, native speakers of Brazilian Portuguese. The auditory tasks of AudBility analyzed in this study were: sound localization (SL), auditory closure (AC), figure-ground (FG), dichotic digits—binaural integration (DD), temporal resolution (TR) and temporal frequency ordering (TO-F). In the second stage, 112 children attended to CAP assessment in the institution’s laboratory. The calculation of efficacy (sensitivity/specificity) was obtained through the construction of the ROC curve for the tests with more than five children altered in the diagnosis. Results For the 6–7-year-old age group the accuracy values were: AC (76.9%); FG (61.6%); DD 78.8% for the right ear and 84.4% for the left ear in females and 63.2% for the left ear in males; TR (77.1%) and TO-F (74.4% for the right ear and 82.4% for the left ear). For the 8-year-old age group the values were: FF (76.5%); DD (71.7% for the left ear for females and 77% for the right ear for males); TR (56.5%) and TO-F (54.1% for the right ear and 70% for the left ear). Conclusions AudBility showed variations in sensitivity and specificity values between the auditory tasks and age groups, with better effectiveness in schoolchildren between the ages of 6 and 7 than eight-year-olds, except for the FG task. For screening purposes, the application of the protocol involving five tasks for the 6 to 7-year-olds group and with four tasks for the 8-year-olds group is suggested.

Interaction Component

The auditory steady-state evoked response (ASSR) is a scalp-recorded potential elicited by modulated sounds or repetitive transient sounds presented at a high rate. The binaural interaction component (BIC) of the ASSR equals the difference between the response to binaural stimuli and the sum of the responses to a monaural stimulus presented to the left ear and the right ear. This study examined the effect of the interaural time (ITD) and level (ILD) difference on the BIC of the 80 Hz ASSR. Sixteen human participants with normal hearing were tested. The ITD and ILD were varied from -1.6 to +1.6 msec and from 0 to +12 dB, respectively. The ITD function of the BIC showed a "V" shape, with a 0 value of BIC at ITD 0 msec and a positive BIC at ITD +0.8 to +1.6 msec. For ILD conditions, the BIC displayed negative values, and its amplitude became more negative as the ILD was increased. The results indicate that the ITD and ILD may be processed by different groups of binaural neurons in different pathways. It is suggested that the 80 Hz ASSR provides an objective means for evaluating binaural functions in patients such as those with central auditory processing disorders. Las respuestas evocadas auditivas de estado estable (ASSR) son potenciales de registro en el cráneo generados por sonidos modulados o sonidos repetitivos transitorios presentados a una tasa alta. El componente de interacción biauricular (BIC) de los ASSR iguala la diferencia entre la respuesta a estímulos bi-auriculares y la suma de respuestas a estímulos mono-auriculares presentados al oído derecho y al oído izquierdo. Este estudio examinó el efecto de la diferencia interauricular de tiempo (ITD) y de nivel (ILD) a partir del BIC de un ASSR de 80 Hz. Se evaluaron dieciséis participantes humanos con audición normal. Las ITD y ILD se variaron de -1.6 a +1.6 mseg y de 0 a + 12 dB, respectivamente. La función ITD del BIC mostró una forma en "V", con un valor 0 del BIC con un ITD de 0 mseg y un BIC positivo con un ITD +0.8 a +1.6 mseg. Para condiciones ILD, el BIC mostró valores negativos, y su amplitud se hizo más negativa conforme aumento el ILD. Los resultados indican que el ITD y el ILD pueden ser procesados por grupos diferentes de neuronas bi-auriculares en diferentes vías. Se sugiere que el ASSR de 80 Hz proporciona un medio objetivo para evaluar las funciones bi-auriculares en pacientes como aquellos con trastornos centrales de procesamiento auditivo.

Objectives: to verify the effects of a speech therapy intervention program in children after moderate and severe traumatic brain injury using electrophysiological and behavioral assessment of central auditory processing. Method: Five children aged 9 to 11 years old who suffered closed brain trauma of moderate or severe degree for at least 6 months, right-handed, literate before the injury, diagnosed with Central Auditory Processing and Reading and Writing Disorders. Ten speech therapy intervention sessions were held, covering the area of language and auditory training activities. Children were submitted to electrophysiological evaluation with Long Latency Auditory Evoked Potential and behavioral assessment of central auditory processing, pre and post intervention. Results: Statistically significant, after speech therapy intervention, in the LLAEP with tone burst, there was an improvement in the latencies of the N2 component in both ears and P3 in the right ear. CAPD improves the memory test for verbal sounds in sequence and the speech test with white noise in the right ear. Conclusion: After the speech therapy intervention program in individuals with TBI it was observed: reduction of the latency of the N1 component in the left ear, in the LLAEP with tone burst; reduction of the latencies of the components N1, P2 and N2 in the right and left ears, and for the latency of the P3 only in the right ear, in the LLAEP with complex stimuli and performance improvement in the behavioral tests of central auditory memory processing for verbal sounds in sequence and speech with white noise.
