- Tradução e adaptação de um software de treinamento da escuta no ruído para o português brasileiro(2018) CALARGA, Karenina Santos; ROCHA-MUNIZ, Caroline; JUTRAS, Benoît; SCHOCHAT, ElianeABSTRACT Purpose To translate and to adapt the software “LEB”, verify its effectiveness and playability in a group of students without hearing and / or learning complaints. Methods (I) Effectiveness was investigated by analyzing the performance of two paired groups before and after training in the compressed speech test. The trained group (TG), composed by 22 students aged 9 to 10 years old, received training with the software and the control group (CG), composed by 20 students of the same age, did not receive any type of stimulation; (II) after the training, the subjects of the TG responded to a qualitative evaluation about the software. Results The commands were understood and executed easily and effectively. The questionnaire revealed that LEB was well accepted and stimulating, providing new learning. The GT presented significant evolutions in comparison to the control group. Conclusions The success in the software’s translation, adaptation and gameplay process is evidenced by the observed changes in the auditory closure ability, suggesting its effectiveness for training speech perception in the noise.
- Wideband reflectance in Down syndrome(2016) SOARES, Jordana Costa; UROSAS, Juliana Granja; CALARGA, Karenina Santos; PICHELLI, Tathiany Silva; LIMONGI, Suelly Cecilia Olivan; SHAHNAZ, Navid; CARVALLO, Renata Mota MamedeObjective: Children with Down syndrome (DS) have a high incidence of middle ear disorders and congenital abnormalities of the external, middle and inner ear. Energy reflectance (ER), a wideband acoustic immittance (WAI) measurement parameter, can measure the sound energy reflected or absorbed in the ear canal over a wider range of frequencies more efficiently and faster than conventional single-tone 226 Hz tympanometry. The aim of the present study was to compare the WAI measurements of children with DS with those of typically developing, normal-hearing children according to their tympanometric findings. Methods: Four groups of children with Down syndrome (age range: 2 years and 4 months to 16 years and 3 months; mean age: 8.5 yr) with normal tympanograms (19 ears), flat tympanograms (13 ears), mild negative pressure tympanograms (6 ears between -100 and -199 daPa at the admittance peak) and severe negative pressure tympanograms (4 ears at -200 daPa or lower at the admittance peak) were assessed. All findings were compared with data obtained from 21 ears of a healthy control group (age range: 3 years and 1 month to 13 years and 11 months; mean age: 7.9 yr). The subjects underwent tympanometry with a 226-Hz probe tone frequency and ER measurements along the 200-6,000 Hz range with a chirp stimulus using the Middle-Ear Power Analyzer (MEPA3 - HearID) by Mimosa Acoustics (Champaign, IL), software, version 3.3 [38]. Results: Statistically significant differences were observed in the ER curves for some comparisons between the studied groups. There was also a negative correlation between the static acoustic admittance at the tympanic membrane level and ER measured with a chirp stimulus at 500 and 1,000 Hz. The discriminant analysis technique, which used a chirp stimulus at 1,000 and 1,600 Hz to classify the participants' data based on ER values, achieved a correct classification rate of 59.52% for participants with DS. Conclusion: While groups with abnormal middle ear status, as indicated by tympanometry, showed higher ER values compared to the DS tymp A group and the control group, similar reflectance curves were observed between control group and the DS tymp A group. WAI shows promise as a clinical diagnostic tool in investigating the impact of middle ear disorders in DS group. However, further research is required to investigate this issue in narrower age range group and a larger sample size.
- O Potencial Evocado Auditivo com estímulo de fala pode ser uma ferramenta útil na prática clínica?(2016) ROCHA-MUNIZ, Caroline Nunes; FILIPPINI, Renata; NEVES-LOBO, Ivone Ferreira; RABELO, Camila Maia; MORAIS, Aline Albuquerque; MURPHY, Cristina Ferraz Borges; CALARGA, Karenina Santos; LEITE, Libia Camargo Ribeiro; PIRES, Mayra Monteiro; SENA-YOSHINAGA, Taise Argolo; SCHOCHAT, ElianeABSTRACT Purpose : To discuss the clinical applicability of the speech-evoked Auditory Brainstem Response (speech-evoked ABR) to help identifying auditory processing disorders. Methods : We analyzed the records of 27 children and adolescents, aged between seven and 15, who presented abnormal speech-evoked ABR. Then, the data from the behavioral auditory processing evaluation of these individuals were surveyed. Results : It was observed that, among the 27 children with abnormal speech-evoked ABR, 23 also had auditory processing disorders. Therefore, from this sample, an 85.15% probability of observing abnormal behavioral assessment of auditory processing in a child who presented abnormal speech-evoked ABR was obtained. Conclusion : It is argued that the speech-evoked ABR can be used in clinical practice as an important aid tool in the diagnosis of auditory processing disorder, because, in this study, an abnormal speech-evoked ABR usually represented a deficit in the results of behavioral assessment of auditory processing. Thus, it can be used to obtain information about the perception of speech sounds in children under seven years or with challenging behavioral assessment.
