Background: Patients with hearing disturbance will generally undergo pure tone audiometry andspeech audiometry in a quiet room, but those examinations cannot evaluate the ability to understand speech in daily environment with a noisy background. Words in noise test will provide valuable informationregarding patient’s hearing problem in noise. Purpose: To evaluate the hearing threshold using wordsin noise test in adults with normal hearing. Method: This cross-sectional study was conducted in CiptoMangunkusumo Hospital from January to April 2017. All subjects who fulfilled the inclusion and exclusioncriteria underwent pure tone audiometry, speech audiometry, and words in noise test. Results: A total of71 individuals with normal hearing were recruited for this study. Words in noise test showed the medianvalue of 67 dB and 100 dB for Speech Recognition Threshold (SRT) 50% and Speech DiscriminationScore (SDS) 100%, respectively. The SRT 50% and SDS 100% were significantly higher in the age group40–60 years compared to the age group 18–39 years. There was also a statistically significant differencebetween males and females at SRT 50% assessed by words in noise audiometry. Conclusion: Wordsin noise test showed a statistically significant difference in SRT 50% and SDS 100% between two agegroups, but no difference was found between genders. The result of this study can be used as a referencefor SRT and SDS values of speech audiometry test in noise.Keywords: words in noise, speech audiometry, speech recognition threshold, speech discrimination score ABSTRAKLatar belakang: Pasien dengan gangguan pendengaran umumnya menjalani pemeriksaanaudiometri nada murni dan audiometri tutur di ruangan yang sunyi, tetapi pemeriksaan ini tidakdapat menggambarkan kemampuan pemahaman wicara di lingkungan sehari-hari yang ramai.

Method Of Paired Comparisons

Children’s subjective judgments of speech clarity using the methods of paired comparisons and category rating were evaluated in this investigation. Eighty children with normal hearing between the ages of 4 and 8 years judged the clarity of sentences that were systematically bandpass-filtered using conditions that increased intelligibility as estimated by the Articulation Index. Subjects were classified into four age groups (4-, 5-, 6-, and 7–8-year age groups) with 20 subjects per group. With use of materials and training methods suitable for children, judgments were obtained via the two psychophysical procedures (10 subjects per age group for each procedure). Results indicated that children 5 years of age and older were able to make reliable clarity judgments using either procedure; however, the method of paired comparisons was more sensitive than category rating in detecting differences between the bandpass-filtered conditions.

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.

AbstractThere are two parts to this article. The first is a general overview of how hearing aid classification works, including a comparison study of normal-hearing listeners and multiple manufacturers' hearing aids while listening to a sound parkour composed of a multitude of acoustic scenes. Most hearing aids applied nearly identical classification for simple listening environments. But differences began to appear across manufacturers' products when the listening environments became more complex. The second section reviews the results of a study of the acoustic ecology (listening environments) experienced by several cohorts of hearing aid users over a 4-month period. The percentages of time people spent in seven different listening environments were mapped. It was learned that they spent an average of 57% of their time in conversation and that age is not a good predictor of the amount of time spent in most listening environments. This is because, when grouped by age, there was little to no difference in the distribution of time spent in the seven listening environments, whereas there was tremendous variability within each age group.

Abstract Some studies in the literature indicate that deaf individuals seem to develop a higher level of attention and concentration during the process of constructing of different ways of communicating. Objective: The aim of this study was to evaluate the level of attention in individuals deaf from birth that worked with computers. Methods: A total of 161 individuals in the 18-25 age group were assessed. Of these, 40 were congenitally deaf individuals that worked with computers, 42 were deaf individuals that did not work, did not know how to use nor used computers (Control 1), 39 individuals with normal hearing that did not work, did not know how to use computers nor used them (Control 2), and 40 individuals with normal hearing that worked with computers (Control 3). Results: The group of subjects deaf from birth that worked with computers (IDWC) presented a higher level of focused attention, sustained attention, mental manipulation capacity and resistance to interference compared to the control groups. Conclusion: This study highlights the relevance sensory to cognitive processing.

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.

Important Diagnostic Tool

Speech audiometry in noise based on sentence tests is an important diagnostic tool to assess listeners’ speech recognition threshold (SRT), i.e., the signal-to-noise ratio corresponding to 50% intelligibility. The clinical standard measurement procedure requires a professional experimenter to record and evaluate the response (expert-conducted speech audiometry). The use of automatic speech recognition enables self-conducted measurements with an easy-to-use speech-based interface. This article compares self-conducted SRT measurements using smart speakers with expert-conducted laboratory measurements. With smart speakers, there is no control over the absolute presentation level, potential errors from the automated response logging, and room acoustics. We investigate the differences between highly controlled measurements in the laboratory and smart speaker-based tests for young normal-hearing (NH) listeners as well as for elderly NH, mildly and moderately hearing-impaired listeners in low, medium, and highly reverberant room acoustics. For the smart speaker setup, we observe an overall bias in the SRT result that depends on the hearing loss. The bias ranges from +0.7 dB for elderly moderately hearing-impaired listeners to +2.2 dB for young NH listeners. The intrasubject standard deviation is close to the clinical standard deviation (0.57/0.69 dB for the young/elderly NH compared with 0.5 dB observed for clinical tests and 0.93/1.09 dB for the mild/moderate hearing-impaired listeners compared with 0.9 dB). For detecting a clinically elevated SRT, the speech-based test achieves an area under the curve value of 0.95 and therefore seems promising for complementing clinical measurements.
