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.

AbstractObjectiveThe current circumstances of the coronavirus disease 2019 pandemic necessitate the use of personal protective equipment in hospitals. N95 masks and face shields are being used as personal protective equipment to protect from aerosol-related spread of infection. Personal protective equipment, however, hampers communication. This study aimed to assess the effect of using an N95 mask and face shield on speech perception among healthcare workers with normal hearing.MethodsTwenty healthcare workers were recruited for the study. Pure tone audiometry was conducted to ensure normal hearing. Speech reception threshold and speech discrimination score were obtained, first without using personal protective equipment and then repeated with the audiologist wearing an N95 mask and face shield.ResultsA statistically significant increase in speech reception threshold (mean of 12.4 dB) and decrease in speech discrimination score (mean of 7 per cent) was found while using the personal protective equipment.ConclusionUse of personal protective equipment significantly impairs speech perception. Alternate communication strategies should be developed for effective communication.

AbstractIn the quest for hearing preservation in patients with acoustic schwannomas it is essential that surgeons do not lose sight of the concept of ‘useful’ hearing. There is an important difference between hearing preservation which pleases the surgeon and that which will be appreciated by the patient.Tumour size, pure tone audiogram average differences between ears and speech discrimination scores have been recorded in a series of 114 patients with unilateral acoustic schwannomas. Criteria for useful hearing are presented in terms of pure tone audiogram average difference and speech discrimination scores.There were 11 patients (10 per cent) with a speech discrimination score of 50 per cent or more, a pure tone audiogram average difference of 30 dB or better and a tumour size of no more than 2 cm. Only one patient (0.9 per cent) had a speech discrimination score of 50 per cent or more, a pure tone audiogram average difference of 20 dB or better and a tumour size of no more than 1 cm.It is concluded that hearing preservation techniques may be applicable to between 1 and 10 per cent of patients with unilateral acoustic schwannomas.

Articulation functions were generated on a normal-hearing population with the Auditec of St. Louis cassette recordings of the NU-6 and CID W-22 speech discrimination tests. Both tests were similar and yielded slopes of about 4.4%/dB. Each gave a speech discrimination score of approximately 95% at 32 dB SL. Speech reception thresholds were obtained with monitored live voice and yielded good testretest consistency. Speech thresholds were about 9 dB better than the ANSI (1969) specifications.

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 Preservation Surgery

Object Hearing preservation remains a challenging problem in vestibular schwannoma (VS) surgery. The ability to preserve hearing in patients with large tumors is subject to particular difficulty. In this study, the authors focus on hearing preservation in patients harboring large VSs. Methods A total of 344 consecutive patients underwent surgical removal of VSs over the past 9 years. Of these 344 cases, 195 VSs were > 20 mm in maximum cisternal diameter. Of the 195 cases, hearing preservation surgery was attempted for 54 patients who had a Class A, B, C, or D preoperative hearing level; that is, a pure tone average ≤ 60 dB and speech discrimination score ≥ 50% according to the Sanna/Fukushima classification. The tumors were classified as moderately large (21–30 mm based on the largest extrameatal diameter), large (31–40 mm), and giant (≥ 41 mm) according to the international criteria. The authors categorized patients with Class A, B, C, D, or E hearing (pure tone average ≤ 80 dB and speech discrimination score ≥ 40%) as having preserved hearing postoperatively. Results Forty-one tumors (75.9%) were totally removed and 13 (24.1%) had near-total removal. Of the 54 patients, 29 maintained their hearing postoperatively; the overall hearing preservation rate was 53.7%. Analysis based on the preoperative hearing level showed that hearing was preserved in 14 (77.8%) of 18 cases for Class A; in 8 (47.1%) of 17 cases for Class B; in 4 (57.1%) of 7 cases for Class C; and in 3 (25.0%) of 12 cases for Class D. In addition, according to the analysis based on the tumor size, 20 (52.6%) of 38 patients with moderately large tumors retained their hearing, as did 5 (50.0%) of 10 patients with large tumors and 4 (66.7%) of 6 patients with giant tumors. Complications included 2 cases of bacterial meningitis that were cured by intravenous injection of antibiotics, 3 cases of subcutaneous CSF leakage that resolved without any surgical repair, and 1 case of temporary abducent nerve palsy. There were no deaths in this series. Conclusions The results indicate that successful hearing preservation surgery in large VSs is possible with meticulous technique and attention to adhesions between the tumor and the cochlear nerves.

Speech Recognition In Noise

Background: The Speech Recognition in Noise Test (SPRINT) is a word-recognition instrument that presents the 200 Northwestern University Auditory Test No. 6 (NU-6) words binaurally at 50 dB HL in a multitalker babble at a 9 dB signal-to-noise ratio (S/N) (Cord et al, 1992). The SPRINT was developed by and used by the Army as a more valid predictor of communication abilities (than pure-tone thresholds or word-recognition in quiet) for issues involving fitness for duty from a hearing perspective of Army personnel. The Words-in-Noise test (WIN) is a slightly different word-recognition task in a fixed level multitalker babble with 10 NU-6 words presented at each of 7 S/N from 24 to 0 dB S/N in 4 dB decrements (Wilson, 2003; Wilson and McArdle, 2007). For the two instruments, both the babble and the speakers of the words are different. The SPRINT uses all 200 NU-6 words, whereas the WIN uses a maximum of 70 words. Purpose: The purpose was to compare recognition performances by 24 young listeners with normal hearing and 48 older listeners with sensorineural hearing on the SPRINT and WIN protocols. Research Design: A quasi-experimental, mixed model design was used. Study Sample: The 24 young listeners with normal hearing (19 to 29 years, mean = 23.3 years) were from the local university and had normal hearing (≤20 dB HL; American National Standards Institute, 2004) at the 250–8000 Hz octave intervals. The 48 older listeners with sensorineural hearing loss (60 to 82 years, mean = 69.9 years) had the following inclusion criteria: (1) a threshold at 500 Hz between 15 and 30 dB HL, (2) a threshold at 1000 Hz between 20 and 40 dB HL, (3) a three-frequency pure-tone average (500, 1000, and 2000 Hz) of ≤40 dB HL, (4) word-recognition scores in quiet ≥40%, and (5) no history of middle ear or retrocochlear pathology as determined by an audiologic evaluation. Data Collection and Analysis: The speech materials were presented bilaterally in the following order: (1) the SPRINT at 50 dB HL, (2) two half lists of NU-6 words in quiet at 60 dB HL and 80 dB HL, and (3) the two 35-word lists of the WIN materials with the multitalker babble fixed at 60 dB HL. Data collection occurred during a 40–60 minute session. Recognition performances on each stimulus word were analyzed. Results: The listeners with normal hearing obtained 92.5% correct on the SPRINT with a 50% point on the WIN of 2.7 dB S/N. The listeners with hearing loss obtained 65.3% correct on the SPRINT and a WIN 50% point at 12.0 dB S/N. The SPRINT and WIN were significantly correlated (r = −0.81, p < .01), indicating that the SPRINT had good concurrent validity. The high-frequency, pure-tone average (1000, 2000, 4000 Hz) had higher correlations with the SPRINT, WIN, and NU-6 in quiet than did the traditional three-frequency pure-tone average (500, 1000, 2000 Hz). Conclusions: Graphically and numerically the SPRINT and WIN were highly related, which is indicative of good concurrent validity of the SPRINT.

The Stability

This study was undertaken to determine the stability of hearing in patients over an eight-year period following a wire-vein graft stapedectomy procedure for otosclerosis. The method was to compare the four-month and eight-year postoperative hearing test results for a population of 76 patients who had undergone this procedure. No significant decrements in pure-tone thresholds were shown over the eight years for the speech frequencies (500, 1000, 2000 Hz). Decrements of approximately 0.5 dB and 1 dB per year over the eight-year period occurred for 4000 and 8000 Hz, respectively. These decrements did not seem to be associated with aging. A slight decrement of 2.8 percentage points in mean speech discrimination score was shown over the eight-year period, while no change occurred in mean speech reception threshold. There were no serious postoperative complications for this group of patients. These results indicated good stability of hearing over the eight years.

Objective To outline the audiological findings of aphasic patients after cerebrovascular accidents.Methods This is a cross-sectional study performed between March 2011 and August 2012 in the Speech, Language, and Hearing Pathology Department of theUniversidade Federal de São Paulo. A total of 43 aphasic subjects (27 men) were referred for audiological evaluation after stroke, with mean age of 54.48 years. Basic audiological evaluation tests were performed, including pure tone audiometry, speech audiometry (speech recognition threshold and word recognition score), immittance measures (tympanometry and contralateral acoustic reflex), and transient otoacoustic emissions.Results Sensorineural hearing loss was prevalent (78.6%). Speech recognition threshold and word recognition score were not obtained in some patients because they were unable to perform the task. Hearing loss was a common finding in this population.Conclusion Comprehension and/or oral emission disruptions in aphasic patients after stroke compromised conventional speech audiometry, resulting in the need for changes in the evaluation procedures for these patients.

AbstractObjective:To determine the efficacy of intratympanic methylprednisolone injections for treating sudden sensorineural hearing loss.Method:A retrospective chart review was performed to identify patients suffering from sudden sensorineural hearing loss with no recovery after oral steroids. Patients were given up to three intratympanic methylprednisolone injections at one-week intervals. They were classified according to their functional hearing class, remission was monitored and potential factors affecting prognosis were analysed.Results:Intratympanic injections provide effective salvage therapy for sudden sensorineural hearing loss (p = 0.039). Changes in pure tone average and speech discrimination score were analysed following intratympanic methylprednisolone injections. The pure tone average reached a plateau after the second injection; however, the speech discrimination score improved until after the third injection. Hearing improvement after intratympanic injections mainly occurred at low frequencies. The interval between symptoms appearing and intratympanic injections starting was not significantly associated with remission (p = 0.680).Conclusion:A delay between symptom onset and the first intratympanic methylprednisolone injection does not seem to affect prognosis.

Purpose The effects of neurological diseases on the auditory system have been a notable issue for investigators because the auditory pathway is closely associated with neural systems. The purposes of this study are to evaluate the efferent auditory system function and hearing quality in Parkinson's disease (PD) and to compare the findings with age-matched individuals without PD to present a perspective on aging. Method The study included 35 individuals with PD (mean age of 48.50 ± 8.00 years) and 35 normal-hearing peers (mean age of 49 ± 10 years). The following tests were administered for all participants: the first section of the Speech, Spatial and Qualities of Hearing Scale; pure-tone audiometry, speech audiometry, tympanometry, and acoustic reflexes; and distortion product otoacoustic emissions (DPOAEs) and contralateral suppression of DPOAEs. SPSS Version 25 was used for statistical analyses, and values of p < .05 were considered statistically significant. Results There were no statistically significant differences in the pure-tone audiometry thresholds and DPOAE responses between the individuals with PD and their normal-hearing peers ( p = .732). However, statistically significant differences were found between the groups in suppression levels of DPOAEs and hearing quality ( p < .05). In addition, a statistically significant and positive correlation was found between the amount of suppression at some frequencies and the Speech, Spatial and Qualities of Hearing Scale scores. Conclusions This study indicates that medial olivocochlear efferent system function and the hearing quality of individuals with PD were affected adversely due to the results of PD pathophysiology on the hearing system. For optimal intervention and follow-up, tasks related to hearing quality in daily life can also be added to therapies for PD.
