Vowel production in hearing impaired children: A comparison between normal-hearing, hearing-aided and cochlear-implanted children.

Introduction And Objectives: Inadequate auditory feedback in prelingually deaf children alters the articulation of consonants and vowels. The purpose of this investigation was to compare vowel production in Spanish-speaking deaf children with cochlear implantation, and with hearing-aids with normal-hearing children by means of acoustic analysis of formant frequencies and vowel space.

Methods: A total of 56 prelingually deaf children (25 with cochlear implants and 31 wearing hearing-aids) and 47 normal-hearing children participated.

Auditory-steady-state response reliability in the audiological diagnosis after neonatal hearing screening.

Introduction And Objectives: Conventional audiometry is the gold standard for quantifying and describing hearing loss. Alternative methods become necessary to assess subjects who are too young to respond reliably. Auditory evoked potentials constitute the most widely used method for determining hearing thresholds objectively; however, this stimulus is not frequency specific.

[Validation of the Spanish parent satisfaction questionnaire with neonatal hearing screening programs].

Introduction: Although measuring parent satisfaction has been recommended as one of the important outcome measures in assessing the effectiveness of neonatal hearing screening programs, there are few published studies investigating this issue.

Objectives: To validate the Spanish version of the Parent Satisfaction Questionnaire with Neonatal Hearing Screening Program (PSQ-NHSP).

Methods: 112 parents whose children had received hearing screening participated in this study.

[Incidence of hypoacusia secondary to hyperbilirubinaemia in a universal neonatal auditory screening programme based on otoacoustic emissions and evoked auditory potentials].

Introduction: Hyperbilirubinaemia is a neonatal risk factor that has been proved to be associated with sensorineural hearing loss. A high concentration of unconjugated bilirubin place newborn children at risk of suffering toxic effects, including hypoacusia.

Objectives: Review of the newborn screening results with a diagnosis of pathological hyperbilirubinaemia as part of a hearing-loss early detection protocol in the general population based on otoemissions and evoked potentials.
