Deaf college students were used to determine quantitative sentence familiarity and lipreading values of the John Tracy Clinic Filmed Test of Lipreading (Taaffe, 1957). There was a low positive correlation between sentence familiarity and the lipreading values. The familiarity and lipreading values of the hearing-impaired subjects were compared with those previously obtained from normal-hearing college students (Lloyd, 1964; Taaffe, 1957).

Σκοπός: Σκοπός αυτής της μελέτης ήταν η ανάπτυξη της Δοκιμασίας -Τέστ, το G-SEBSAT τέστ, στην ακουστική ομιλία βασισμένο σε προτάσεις για παιδιά με προβλήματα ακοής.Μέθοδοι: Προσλήφθηκαν εβδομήντα έξι παιδιά κατόπιν έγκρισης από την τοπική επιτροπή δεοντολογίας και κατόπιν ενημέρωσης από τους γονείς τους. Η συλλογή του λεξιλογίου βασίστηκε στην προβολή εικόνων που επιλέχθηκαν από δημοφιλείς αναγνωστικές ύλες στα ελληνικά στα παιδιά με προβλήματα ακοής (Hearing Impaired-ΗΙ). Εκπονήθηκε μια γραμματική ανάλυση περιεχομένου για να προσδιοριστούν οι μέσες συντακτικές και μορφολογικές δομές των φράσεων που χρησιμοποιούνται από τα παιδιά της ΗΙ ομάδας . Δέκα λίστες που σχετίζονται με αντοίστοιχες εικόνες, δημιουργήθηκαν με βάση το λεξιλόγιο και τη γραμματική ανάλυση και καταγράφηκαν από έναν άνδρα ομιλητή με μητρική του γλώσσα την σύγχρονη ελληνική. Οι δέκα λίστες παρουσιάστηκαν σε παιδιά με κανονική ακοή (Normal Hearing-NH) και σε παιδιά με HI, ενώ και στις δύο ομάδες καταγράφηκε το μέσο όριο απόκρισης ομιλίας (Speech Reception Threshold-SRT) καθώς και η κλίση της καμπύλης SRT στο επίπεδο SRT των 50% σωστών αποκρίσεων (S50). Οι κατάλογοι καταγγελιών επικυρώθηκαν σε σχέση με τη μεταβλητότητα της δυσκολίας τους σε κάθε ομάδα, καθώς και με τη μεταβλητότητα δοκιμής-επανεξέτασης των αντίστοιχων βαθμολογιών SRT.Αποτελέσματα: Το μέσο όριο απόκρισης ομιλίας (SRT) σε όλες τις λίστες για παιδιά με ΗΙ ήταν 65,27 dB και η κλίση της καμπύλης SRT στο επίπεδο SRT των 50% των σωστών αποκρίσεων ήταν 3,11% / dB. Τα αντίστοιχα αποτελέσματα σε όλους τους καταλόγους για τα παιδιά με NH ήταν 17,66 dB και 9,7% / dB αντίστοιχα. Τα SRT των παιδιών με ΗΙ συσχετίστηκαν έντονα θετικά, με στατιστικά σημαντικό τρόπο με την μέτρηση ακουστικού τόνου (Pure Tone Audiometry-ΡΤΑ) τόσο στις δοκιμασίες όσο και στις δοκιμαστικές συνεδρίες (δοκιμασία: r = 0.750, Ρ <0.0005, επανέλεγχος: r = 0.753, Ρ <0.0005). Η συσχέτιση Spearman των βαθμολογιών των τιμών SRT και των τιμών κλίσης ήταν 0.998 και 0.997 αντίστοιχα για το ΗΙ και 0.939 και 0.88 για την ομάδα με ΝΗ, υποδεικνύοντας πολύ χαμηλή μεταβλητότητα σε όλες τις συνεδρίες δοκιμής και επανεξέτασης. Επιπλέον, η ανάλυση της διακύμανσης (ANOVA) του μέσου SRT στα παιδιά με NH και τα υπολείμματα SRT στην ομάδα με HI έδειξε ότι οι διαφορετικές προτάσεις ήταν της ίδιας δυσκολίας σε κάθε ομάδα. ((F (9,81) = 0,401, ρ = 0,930 και (F (9,93) = 2,241, ρ = 0,025 αντίστοιχα).Συμπεράσματα: Για πρώτη φορά δημιουργήθηκε στην ελληνική γλώσσα επικυρωμένη δοκιμή ομιλίας ακουστικής φωνής. Οι τιμές SRT και S50 και για τα παιδιά με NH και με HI είναι συγκρίσιμες με παρόμοιες δοκιμές που αναπτύχθηκαν σε άλλες γλώσσες.

Hearing-impaired persons usually perceive speech by watching the face of the talker while listening through a hearing aid. Normal-hearing persons also tend to rely on visual cues, especially when they communicate in noisy or reverberant environments. Numerous clinical and laboratory studies on the auditory-visual performance of normal-hearing and hearing-impaired children and adults demonstrate that combined auditory-visual perception is superior to perception through either audition or vision alone. This paper reviews these studies and provides a rationale for routine evaluation of auditory-visual speech perception in audiology clinics.

Impaired Children

Speech audiometry is an essential part of the assessment of hearing impaired children and it is now widely used throughout the United Kingdom. Although instructions are universally agreed upon as an important aspect in the administration of any form of audiometric testing, there has been little, if any, research towards evaluating the influence which instructions that are given to a listener have on the Speech Reception Threshold obtained. This study attempts to evaluate what effect guessing has on the Speech Reception Threshold of children. A sample of 30 secondary school pupils between 16 and 18 years of age with normal hearing was used in the study. It is argued that the type of instruction normally used for Speech Reception Threshold in audiometric testing may not provide a sufficient amount of control for guessing and implications of this, using data obtained in the study, are examined.

Hearing Impaired Children

The benefits of amplification for sensorineural hearing-impaired persons listening at low levels were investigated. Eleven college students were tested, and the results suggest that the level above threshold at which a person listens to speech may ultimately influence the benefits obtained from amplification. The data indicate the possibility of an additional limitation to the potential for auditory speech communication when these persons cannot listen comfortably at levels above threshold of 20 to 30 dB or more.

The Impact

Objectives This study investigates the hypothesis that hearing aid amplification reduces effort within conversation for both hearing aid wearers and their communication partners. Levels of effort, in the form of speech production modifications, required to maintain successful spoken communication in a range of acoustic environments are compared to earlier reported results measured in unaided conversation conditions. Design Fifteen young adult normal-hearing participants and 15 older adult hearing-impaired participants were tested in pairs. Each pair consisted of one young normal-hearing participant and one older hearing-impaired participant. Hearing-impaired participants received directional hearing aid amplification, according to their audiogram, via a master hearing aid with gain provided according to the NAL-NL2 fitting formula. Pairs of participants were required to take part in naturalistic conversations through the use of a referential communication task. Each pair took part in five conversations, each of 5-min duration. During each conversation, participants were exposed to one of five different realistic acoustic environments presented through highly open headphones. The ordering of acoustic environments across experimental blocks was pseudorandomized. Resulting recordings of conversational speech were analyzed to determine the magnitude of speech modifications, in terms of vocal level and spectrum, produced by normal-hearing talkers as a function of both acoustic environment and the degree of high-frequency average hearing impairment of their conversation partner. Results The magnitude of spectral modifications of speech produced by normal-hearing talkers during conversations with aided hearing-impaired interlocutors was smaller than the speech modifications observed during conversations between the same pairs of participants in the absence of hearing aid amplification. Conclusions The provision of hearing aid amplification reduces the effort required to maintain communication in adverse conditions. This reduction in effort provides benefit to hearing-impaired individuals and also to the conversation partners of hearing-impaired individuals. By considering the impact of amplification on both sides of dyadic conversations, this approach contributes to an increased understanding of the likely impact of hearing impairment on everyday communication.
