Frequency-Following Response with Speech Stimulus: Comparison between Two Methods of Stimulation.

 Frequency-following response with speech stimulus (FFR-speech) is a subcortical potential that satisfactorily evaluates the processing of verbal information. However, there still are differences in the literature regarding its analysis and stimulation protocol.  To compare two stimulation protocols for the capture of FFR-speech, to identify the percentage of occurrence of the waves among them and to compare it with the specialized literature, as well as to describe the interpeaks of its waves.

High-frequency auditory thresholds in normal hearing adults.

Purpose: Evaluate high-frequency auditory thresholds, seeking to compare responses between the ears, to verify the correlation between hearing level and aging and analyze frequency responses in normal hearing adults.

Methods: This is a prospective, quantitative, transversal study conducted with a convenience sample. Study participants were 60 individuals aged 18 to 58 years (mean=25.
