Dichotic sentence identification test in Portuguese: a study in young adults.

Introduction: Among the currently-applied auditory processing tests, dichotic listening tests have been widely used, since they allow investigating the hemispheric and inter-hemispheric function and their respective skills to process the received auditory information.

Objective: To obtain normality reference measures with the new dichotic sentence identification test in right-handed adults with normal hearing.

Methods: Quantitative, observational, cross-sectional study.

Auditory evoked potential P300 in adults: reference values.

Objective: To establish reference intervals for cognitive potential P300 latency using tone burst stimuli.

Methods: This study involved 28 participants aged between 18 and 59 years. P300 recordings were performed using a two-channel device (Masbe, Contronic).

Proposal for implementing the Sentence Recognition Index in individuals with hearing disorders.

Purpose: To present and describe a new strategy and protocol for obtaining the Sentences Recognition Indexes (SRI), using the Lists of Phrases in Portuguese test (LPP), considering words in the analysis of responses; to analyze and compare the results using the previous and the new strategies by checking their applicability and suitability.

Methods: To consider each word of the sentence, words were classified according to their importance: functional and content words, assigning them, respectively, two and one points. SRI were obtained in 33 normal hearing adults, and results were compared using the two strategies.

Bilingualism and auditory processing abilities: performance of adults in dichotic listening tests.

Purpose: To evaluate and compare the dichotic listening abilities in non-hearing-impaired adults monolingual speakers of the Brazilian Portuguese language (CG) and simultaneous Brazilian Portuguese-German (GG) bilingual speakers or successive Brazilian Portuguese-Italian bilingual speakers (IG).

Methods: This is about an observational, descriptive, transverse and quantitative research. The sample consisted of 87 subjects aged between 18 and 55 years, divided into: Control Group (CG), of 30 monolingual speakers of Brazilian Portuguese; Study Group A (SGA), of 31 simultaneous Brazilian Portuguese-German bilingual speakers; and Study Group I (SGI), of 26 successive Brazilian Portuguese-Italian speakers.

Acclimatization effect in speech recognition: evaluation without hearing aids.

Background: After the adaptation of hearing aids, an improvement in speech understanding is expected to occur, called acclimatization.

Aim: To determine the effect of acclimatization in sentences recognition threshold, for the conditions of silence (SRTQ) and noise (SRTN), in new users of hearing aids, evaluated prior to and after acclimatization, without the use of the hearing aids.

Method: Participants were 40 individuals, aged between 28 and 78 years, with mild to moderate sensorineural hearing loss.

Speech recognition according to the length of hearing aid use.

Unlabelled: The use of hearing aids can provide plasticity to the hearing system as well as improve speech recognition as time goes by.

Aim: To compare the influence of the length of hearing aid use on the benefit obtained with the hearing aids in adults and the elderly, new hearing aids users.

Materials And Methods: Prospective study with 40 individuals with mild to moderate-severe sensorineural hearing loss, gathered in 2 groups: Adults Group--13 people aged between 28 and 59 years old; and Elderly Group--27 people aged between 61 and 78 years old.
