    PURPOSE: To develop the Brazilian Portuguese version of the dichotic sentence idenfication test (DSI). METHODS: The sentences used in the Portuguese version of DSI test were extracted from the Synthetic Sentece Identification (SSI) test in Portuguese. A method of combination was used in order to create 45 pairs of sentences, each pair corresponding to a test item. The items were divided into five groups, each group corresponding to a specific test condition. For this purpose, a computer program was designed in the Matlab 7.0 computing platform, using the Monte Carlo method, or the brute force method, for the distribution of items in each group. The sentences were edited, recorded and finalized; for manipulation of data it was used the CaKewalk Sonar 2.2 program. Finally, the Sound Forge program was used for finalization and standardization of the recording. RESULTS: As a result, a compact disc with six tracks was obtained to be used as part of the behavioral assessment of auditory processing, including the following tracks: calibration, practice, binaural integration, directed attention to the right and to the left ears. The use of the calibration and auditory training tracks is recommended for use in the rehabilitation of auditory processing disorders. CONCLUSION: The compact disc with the Brazilian Portuguese version of the DSI test consisted of six tracks: calibration, practice, binaural integration, directed attention to the right and to the left ears and auditory training.

    Reconhecimento de fala no nível de máximo conforto em pacientes adultos com perda auditiva neurossensorial

    PURPOSE: To obtain the Percentage Index of Speech Recognition (PISR) at maximum comfortable level (MCL) in adults with mild to moderately severe (up to 60 dB) sensorineural hearing loss. METHODS: The subjects evaluated were grouped according to the degree of hearing loss (Groups I, II and III). The groups were further divided into subgroups (IA,IB, IIA, IIB, IIIA, IIIB) as it follows. In the subgroup A of each group, the PISR was determined at 40 dB SL, beginning with the right ear. The patient was then requested to inform how comfortable the sound was at this level of stimuli presentation, according to a scale with four possibilities: low, comfortable, high and excessively high. After that, the maximum comfortable level (MCL) was obtained, and the PISR was carried out using that intensity level. In the subgroup B of each group, the same procedure was carried out, only reversely, performing initially the PISR at MCL, and then at 40 dB SL. In this subgroup the test began with the left ear. RESULTS: After evaluating the subjects of the three groups, the mean MCL was calculated. It varied from 25 to 32.95 dB SL. The subjects had better results in the PISR when stimuli were presented at MCL. CONCLUSION: PISR evaluation at MCL, for individuals with mild to moderately severe sensorineural hearing loss, provides better Speech Recognition results.
