Masking release in cortical auditory evoked potentials with speech stimulus.

Purpose: To analyze the effect of masking on the Cortical Auditory Evoked Potential with speech stimulus in young adults.

Methods: Fourteen individuals aged between 19 and 28 years of both sexes with no hearing loss participated in the study. The Cortical Auditory Evoked Potential examination was performed with synthetic speech stimulus /ba/ simultaneous to Speech Shaped Noise presented under three conditions: steady noise with a 30 dB SPLep intensity (weak steady noise), steady noise with a 65 dB SPLep intensity o (strong steady noise) and modulated noise with 30 dB SPLep and 65 dB SPLep intensities at 25Hz and modulation period of 40 ms.

Frequency-Following Response and Auditory Behavior in Children with Prenatal Exposure to the Zika Virus.

 Prenatal exposure to the Zika virus can impair neurodevelopment and cause auditory damage.  To analyze the frequency-following response (FFR) and the auditory behavior (with the questionnaire) of children with and without prenatal exposure to Zika virus infection.  A total of 30 children participated in the present study, divided into 3 groups: 10 children with microcephaly and prenatal exposure to the Zika virus; 10 normocephalic children with prenatal exposure to the Zika virus; and 10 children with no evidence of prenatal exposure to the virus.

The effect of noise on the amplitude and morphology of cortical auditory evoked potentials.

Objective: To analyze the effect of noise on electrophysiological measurements (P1-N1-P2 complex) of cortical auditory evoked potentials in normal hearing individuals of different ages.

Methods: The inclusion criteria for the study were young individuals, adults and elderly, aged 18-75 years, with auditory thresholds up to 25 dB. Participants were separated according to their age group: G1 (18-25 years old), G2 (31-59 years old) and G3 (60-75 years old).

Frequency Following Responses in childhood apraxia of speech.

Objective: to compare the Frequency Following Responses of children with childhood apraxia of speech with typical development children.

Method: this is an observational cross-sectional analytical study approved by Human Research Ethics Committee. Thirty normal hearing children have participated in the study.

Effect of Forward Masking on Frequency Following Response as a Function of Age.

Background: Forward masking occurs when noise is presented before the target signal, making the latter difficult to be perceived. It is related to temporal auditory processing and consequently to speech recognition in noisy environments, which may decline with age. Interest in forward masking has grown in the last years.

Instrument for evaluating child hearing health services: construction and validity.

Objective: To validate a matrix of indicators to assess the structure and process of child hearing health services.

Method: A study of semantic and content validation with specialists in the area of Nursing and Speech therapy. The instrument contained 20 indicators with scores to be analyzed by experts.

Family Health Team: reports of conduct on child hearing loss.

Purpose: To analyze the performance of family health teams toward the suspicion and identification of child hearing loss.

Methods: This is a case study. Data were collected in three focus groups with three family health teams of a health district in the metropolitan area of Recife, Brazil.

Brazilian Portuguese Hearing in Noise Test (HINT): different interpretation criteria for individuals' responses.

Introduction: The ability to recognize the sounds of speech enables an efficient communication. This ability must always be considered when communication disorders are evaluated. In this study, sentences of the Hearing in Noise Test (HINT), originally developed in English and adapted to Brazilian Portuguese, were used to evaluate speech recognition in silence and in the presence of noise.

Masking Period Patterns and Forward Masking for Speech-Shaped Noise: Age-Related Effects.

Objective: The purpose of this study was to assess age-related changes in temporal resolution in listeners with relatively normal audiograms. The hypothesis was that increased susceptibility to nonsimultaneous masking contributes to the hearing difficulties experienced by older listeners in complex fluctuating backgrounds.

Design: Participants included younger (n = 11), middle-age (n = 12), and older (n = 11) listeners with relatively normal audiograms.

Modulation masking release using the Brazilian-Portuguese HINT: psychometric functions and the effect of speech time compression.

Objective: The Brazilian-Portuguese hearing in noise test (HINT) was used to investigate the benefit to speech recognition of listening in a fluctuating background. The goal was to determine whether modulation masking release varied as a function of the speech-to-masker ratio at threshold. Speech-to-masker ratio at threshold was manipulated using the novel approach of adjusting the time-compression of the speech.

[Child hearing health: practice of the Family Health Strategy nurses].

Objective: Evaluating the practice of nurses of the Family Health Strategy (FHS) in child hearing health care.

Method: A normative assessment of structure and process, with 37 nurses in the Family Health Units, in the city of Recife, Pernambuco. The data collection instrument originated from the logical model of child hearing health care provided by nurses of the Family Health Strategy, and the matrix of indicators for evaluation of nursing practice.

Newborn and infant hearing health education for nursing professionals.

Unlabelled: Hearing loss is a sensory deprivation, which can brings several consequences, among them: language development delay, emotional and social problems, and school difficulties. In such settings, we stress the role of nursing professional, who can expand their knowledge about children's hearing health, all the way from pre-natal care.

Objective: To check the knowledge of nursing professional after the educational actions on pediatric hearing.

Audiologic results in patients with Moebiüs sequence.

Objective: Moebiüs sequence is a pathology not very well understood regarding to the hearing status. The main goal of this study was to describe the audiologic findings in children and adolescent who carry Moebiüs sequence.

Method: Participated in this study 17 children and adolescent, with age ranging from 3 to 13 years old.

Immittance measures in individuals with Moebius Sequence.

Unlabelled: Moebius Sequence has been described as a pathology which involves the VI and VII cranial nerves, causing facial palsy. Acoustic reflexes are elicited by a high intensity stimulation of the stapedius and the tensor tympani muscles. The VII cranial nerve is responsible for innervating the stapedius muscle.
