potential of self conducted Speech Audiometry with smart speakers
Proceedings of the International Symposium on Auditory and Audiological Research, 2019Co-Authors: Jasper Ooster, Melanie Krueger, Jorghendrik Bach, Kirsten C Wagener, Bernd MeyerAbstract:Speech Audiometry in noise based on matrix sentence tests is an important diagnostic tool to assess the Speech reception threshold (SRT) of a subject, i.e., the signal-to-noise ratio corresponding to 50% intelligibility. Although the matrix test format allows for self-conducted measurements by applying a visual, closed response format, these tests are mostly performed in open response format with an experimenter entering the correct/incorrect responses (expert-conducted). Using automatic Speech recognition (ASR) enables self- conducted measurements without the need of visual presentation of the response alternatives. A combination of these self-conducted measurement procedures with signal presentation via smart speakers could be used to assess individual Speech intelligibility in an individual listening environ- ment. Therefore, this paper compares self-conducted SRT measurements using smart speakers with expert-conducted lab measurements. With smart speakers, the experimenter has no control over the absolute presentation level, mode of presentation (headphones vs. loudspeaker), potential errors from the automated response logging, and room acoustics. We present the differences between measurements in the lab and with a smart speaker for normal- hearing, mildly hearing-impaired and moderate hearing-impaired subjects in low, medium, and high reverberation.

verbal response times as a potential indicator of cognitive load during conventional Speech Audiometry with matrix sentences
Trends in hearing, 2018Co-Authors: Hartmut Meister, Sebastian Rahlmann, Ulrike Lemke, Jana BesserAbstract:This study examined verbal response times-that is, the duration from stimulus offset to voice onset-as a potential measure of cognitive load during conventional testing of Speech-in-noise understanding. Response times were compared with a measure of perceived effort as assessed by listening effort scaling. Three listener groups differing in age and hearing status participated in the study. Testing was done at two target intelligibility levels (80%, 95%) and with two noise types (stationary and fluctuating). Verbal response times reflected effects of intelligibility level, noise type, and listener group. Response times were shorter for 95% compared with 80% target intelligibility, shorter for fluctuating compared with stationary noise, and shorter for young listeners compared with older listeners. Responses were also faster for the older listeners with near normal hearing compared with the older hearing-aid users. In contrast, subjective listening effort scaling predominantly revealed effects of target intelligibility level but did not show consistent noise-type or listener-group effects. These findings show that verbal response times and effort scalings tap into different domains of listening effort. Verbal response times can be easily assessed during conventional Speech Audiometry and have the potential to show effects beyond performance measures and subjective effort estimates.

Speech Audiometry Speech perception and cognitive functions german version
Hno, 2017Co-Authors: Hartmut MeisterAbstract:Examination of cognitive functions in the framework of Speech perception has recently gained increasing scientific and clinical interest. Especially against the background of age-related hearing impairment and cognitive decline potential new perspectives in terms of better individualisation of auditory diagnosis and rehabilitation might arise. This review addresses the relationships of Speech Audiometry, Speech perception and cognitive functions. It presents models of Speech perception, discusses associations of neuropsychological with audiometric outcomes and shows recent efforts to consider cognitive functions with Speech Audiometry.

the use of Speech Audiometry in the practice of the geriatric center
Advances in gerontology = Uspekhi gerontologii, 2017Co-Authors: Yu M Boboshko, E V Zhilinskaia, L E Golovanova, T V Legostaeva, F Di Berardino, A CesaraniAbstract:The aim of the study was to evaluate a new test of Speech Audiometry while examining aged patients. Thirty-two aged listeners from 60 to 88 years old were examined: 20 hearing aid (HA) users and 12 patients with normal hearing thresholds and mild cognitive impairment according to the results of the minimental state examination (MMSE). The Speech Audiometry consisted of the traditional polysyllabic word discrimination test and a new Speech test with motor responses (Verbal Tasks and Motor Responses—VTMR); in both tests the Speech signal was presented in background noise (polyphony) in free field. All listeners performed the VTMR test significantly better than the polysyllabic word discrimination test. In the group of hearingimpaired patients the mean result in the VTMR test was 73.2 ± 29.2% without a HA and 88.6 ± 20.5% with it; in the traditional test, 34.8 ± 20.9% without a HA and 56.0 ± 18.4% with it. All patients of the group with normal hearing and mild cognitive impairment performed the VTMR test with a 100% result, their Speech discrimination score in traditional test was 88.0 ± 12.0%. In the practice of the geriatric center the use of both traditional Speech Audiometry and the new Speech test with motor responses seems to be reasonable. It allows examining the auditory function in patients with significant deterioration of Speech intelligibility or cognitive impairment.

vtmr a new Speech Audiometry test with verbal tasks and motor responses
Annals of Otology Rhinology and Laryngology, 2012Co-Authors: Federica Di Berardino, Stella Forti, A CesaraniAbstract:Objectives:The aim of this study was to design a complementary Speech Audiometry test using verbal tasks and motor responses (VTMR) to assess the ability of a subject to understand and perform simple motor tasks with 3-dimensional objects, to describe its construction, and to show the preliminary results of a pilot study on the Italian version of the test.Methods:The items used in the test setting included 1 base, 1 hammer, 1 wooden structure with 4 sticks, and 5 rings of different colors and 20 lists with 5 verbal tasks per list. The VTMR test and bisyllabic Speech Audiometry were evaluated in normal-hearing subjects with and without cognitive impairment and in subjects with sensorineural hearing loss.Results:All normal-hearing subjects without cognitive impairment performed the VTMR tasks (100%) correctly at 35 dB sound pressure level. In subjects with sensorineural hearing loss, the percentage of correct answers was significantly higher for the VTMR test than for bisyllabic Speech Audiometry above 50 d...

influence of compact disk recording protocols on reliability and comparability of Speech Audiometry outcomes acoustic analysis
Journal of Laryngology and Otology, 2010Co-Authors: F Di Berardino, G Tognola, Alessia Paglialonga, D Alpini, F Grandori, A CesaraniAbstract:Objective: To assess whether different compact disk recording protocols, used to prepare Speech test material, affect the reliability and comparability of Speech Audiometry testing. Material and methods: We conducted acoustic analysis of compact disks used in clinical practice, to determine whether Speech material had been recorded using similar procedures. To assess the impact of different recording procedures on Speech test outcomes, normal hearing subjects were tested using differently prepared compact disks, and their psychometric curves compared. Results: Acoustic analysis revealed that Speech material had been recorded using different protocols. The major difference was the gain between the levels at which the Speech material and the calibration signal had been recorded. Although correct calibration of the audiometer was performed for each compact disk before testing, Speech recognition thresholds and maximum intelligibility thresholds differed significantly between compact disks (p < 0.05), and were influenced by the gain between the recording level of the Speech material and the calibration signal. Conclusion: To ensure the reliability and comparability of Speech test outcomes obtained using different compact disks, it is recommended to check for possible differences in the recording gains used to prepare the compact disks, and then to compensate for any differences before testing.

non verbal visual reinforcement affects Speech Audiometry in the elderly
European Archives of Oto-rhino-laryngology, 2010Co-Authors: Federica Di Berardino, Stella Forti, A Cesarani, Valentina Mattei, Dario AlpiniAbstract:The purpose of this study was to investigate how non-verbal visual reinforcement provided by the audiologist during Speech testing influences performance in the elderly. Thirty-two volunteers with age-related hearing loss with or without dual sensory-impairment (DSI), were administered a Speech Audiometry test in which they repeated lists of ten disyllabic words in two different conditions, namely with and without visual reinforcement. In the conditions of “with visual reinforcement”, the tester provided non-verbal cues to acknowledge the response of each participant. The “visual reinforcement” condition did not apparently provide any significant variation in the results. However, when we considered the group of patients without DSI, the non-verbal “visual reinforcement” resulted in better scores (p < 0.001). Non-verbal visual reinforcement may influence Speech Audiometry results in the elderly. During Speech testing of elderly people with age-related hearing loss, audiologists should always remember to administer visual reinforcement to the patients in order to remove a possible confounding factor from audiological evaluation.

pure tone audiogram and Speech Audiometry in patients with hereditary motor and sensory neuropathy
Pflügers Archiv: European Journal of Physiology, 2000Co-Authors: Branka Alcin, Jagoda Vatovec, Miha žargiAbstract:The goal of our work was to determine hearing thresholds in patients with hearing impairment due to hereditary motor and sensory neuropathy(HMSN I). In assessment of auditory function we used two methods: pure tone and Speech Audiometry. Pure tone Audiometry was performed using air and bone conducted signals. Speech comprehension was defined with a test battery of monosyllabic words unknown to the patient. By comparing the results of these methods we were able to differentiate whether the hearing loss was of cochlear or retrocochlear origin. We tested 5 patients with HMSN I associated with difficulty in Speech understanding. The tests showed mild to severe elevation of pure tone thresholds but no Speech perception in any of tested patients. We suggest that this type of hearing impairment be due to the disorder of the auditory nerve function - a neuropathy of the auditory nerve as part of HMSN.
