Background: Children with profound hearing loss can gain access to sound through cochlear implants (CIs), but these devices must be worn consistently to promote auditory development. Although subjective parent reports have identified several [...]Article
Cochlear implants (CIs) give children with severe to profound hearing loss access to sound. There appears to be a dose effect of sound exposure on speech perception abilities as shown by the positive influence of early implantation and CI experi[...]Article
Objectives: To assess the sensitivity of statistical indicators used for the objective detection of speech-evoked envelope following responses (EFRs) in infants and adults. Design: Twenty-three adults and 21 infants with normal hearing particip[...]Article
Spoorthi Thammaiah ; Vinaya Manchaiah ; Vijayalakshmi Easwar ; Rajalakshmi Krishna ; Bradley McPherson |To assess the psychometric properties of the Hearing Handicap Questionnaire (HHQ) in Kannada (a South-Indian language) among adults with hearing loss. Design: The study involved a cross-sectional survey design. Participants provided demographic [...]Article
Objective: Vowel-evoked envelope following responses (EFRs) could be a useful noninvasive tool for evaluating neural activity phase-locked to the fundamental frequency of voice (f0). Vowel-evoked EFRs are often elicited by vowels in consonant-vo[...]Article
Objectives: The objective of the present study was to evaluate the between-session test-retest variability in the characteristics of envelope following responses (EFRs) evoked by modified natural speech stimuli in young normal hearing adults. [...]Article
Objectives: The present study aimed to (1) evaluate the accuracy of envelope following responses (EFRs) in predicting speech audibility as a function of the statistical indicator used for objective response detection, stimulus phoneme, frequency[...]Article
Vijayalakshmi Easwar, Auteur ; David Purcell, Auteur ; Maaike Van Eeckhoutte, Auteur ; Steven J. Aiken, Auteur |The influence of male and female vowel characteristics on the envelope-following responses (EFRs) is not well understood. This study explored the role of vowel characteristics on the EFR at the fundamental frequency (f0) in response to the vowel[...]Article
To evaluate sensation level (SL)-dependent characteristics of envelope following responses (EFRs) elicited by band-limited speech dominant in low, mid, and high frequencies. Design: In 21 young normal hearing adults, EFRs were elicited by 8 mal[...]Article
Objectives: The vowel-evoked envelope following response (EFR) is a useful tool for studying brainstem processing of speech in natural consonant-vowel productions. Previous work, however, demonstrates that the amplitude of EFRs is highly variabl[...]
