ABSTRACT Purpose: to review the scientific literature and present existing instruments and methods for the objective assessment of the listening effort in normal hearing individuals worldwide. Methods: a literature integrative review whose purpose was to gather and summarize the scientific knowledge regarding the objective methods theme for measuring the listening effort, developed through the search of articles in specialized national and international journals, in the English and Portuguese languages, available in the databases: PUBMED, Cochrane Library, LILACS and SCIELO. Results: 18 articles which used physiological methods to measure the listening effort in individuals with normal hearing were reviewed. The main findings described in those articles refer to the author(s) and purpose(s) of the research, country where the research was conducted, casuistry, physiological method used and results. Conclusion: there is no consensus among the researchers about the best physiological method to measure this parameter, that is, this effort in the speech perception tasks, although the level of skin conductance is considered the most accurate measure to date.

Facial (VII th cranial nerve) palsy is a condition that affects 1 in 5000 people worldwide. More recently it has appeared as one form of the  neural manifestations  of  infection  by  the Human  Immunodeficiency Virus. As such it is likely that this condition will feature more prominently in the caseload of physiotherapists.  Therefore the purpose of this paper is to present to physiotherapists existing knowledge on the diagnosis, objective assessment and prognosis of  facial palsy  through a  literature  review. All  available  primary  and  secondary  sources  of  literature  were  obtained through a search of Medline, Sabinet, PEDRO, the Cochrane library and a wide Google search. Objective ways of assessing Bells palsy and its recovery as  used  currently  by  the Belly Palsy Association  and  accepted  by  the American Academy  of Otolaryngology  and Head and Neck, are presented together with diagnosis and prognosis.

Speech perception and listening effort are complicated and interrelated concepts. One might assume that intelligibility performance (percent correct) is a proxy for listening effort, but there are some reasons to challenge whether that is actually true. Correct responses in speech perception tests could reflect effortful mental processing, and a completely wrong answer could evoke very little effort, especially if the misperception itself is linguistically well-formed and sensible. This paper presents evidence that listening effort is not a function of the proportion of words correct, but is rather driven by the types of errors, position of errors within a sentence, and the need to resolve ambiguity, reflecting how easily the listener can make sense of a perception. We offer a taxonomy of error types that is both intuitive and also consistent with data from two experiments measuring listening effort with careful controls to either elicit specific kinds of mistakes or to track specific mistakes retrospectively. Participants included individuals with normal hearing or with cochlear implants. In two experiments of sentence repetition, listening effort – indexed by changes in pupil size – was found to scale with the amount of perceptual restoration needed (phoneme versus whole word), and also scale with the sensibility of responses, but not with the number of intelligibility errors. Although mental corrective action and number of mistakes can scale together in many experiments, it is possible to dissociate them in order to advance toward a more explanatory (rather than correlational) account of listening effort.

Daily-life conversation relies on speech perception in quiet and noise. Because of the COVID-19 pandemic, face masks have become mandatory in many situations. Acoustic attenuation of sound pressure by the mask tissue reduces speech perception ability, especially in noisy situations. Masks also can impede the process of speech comprehension by concealing the movements of the mouth, interfering with lip reading. In this prospective observational, cross-sectional study including 17 participants with normal hearing, we measured the influence of acoustic attenuation caused by medical face masks (mouth and nose protection) according to EN 14683 and of N95 masks according to EN 1149 (EN 14683) on the speech recognition threshold and listening effort in various types of background noise. Averaged over all noise signals, a surgical mask significantly reduced the speech perception threshold in noise was by 1.6 dB (95% confidence interval [CI], 1.0, 2.1) and an N95 mask reduced it significantly by 2.7 dB (95% CI, 2.2, 3.2). Use of a surgical mask did not significantly increase the 50% listening effort signal-to-noise ratio (increase of 0.58 dB; 95% CI, 0.4, 1.5), but use of an N95 mask did so significantly, by 2.2 dB (95% CI, 1.2, 3.1). In acoustic measures, mask tissue reduced amplitudes by up to 8 dB at frequencies above 1 kHz, whereas no reduction was observed below 1 kHz. We conclude that face masks reduce speech perception and increase listening effort in different noise signals. Together with additional interference because of impeded lip reading, the compound effect of face masks could have a relevant impact on daily life communication even in those with normal hearing.

Abstract Daily life conversation relies on speech perception in quiet and noise. Due to the COVID-19 pandemic, the usage of face masks has become mandatory in many situations. Acoustic attenuation of sound pressure by the mask tissue reduces speech perception ability especially in noisy situations. Mask also impede the process of speech information from sight of the moving mouth (lip reading). In a prospective exploratory experimental study including 17 normal hearing participants, speech perception in noise and listening effort were measured with and without a surgical mask or an N95 mask between the speech signal and the listener. Additionally, the influence of the masks on the acoustic frequency spectrum was measured. Averaged over all noise signals, speech perception threshold in noise was significantly reduced by 1.6 dB (95% CI[1.0, 2.1]) by a surgical mask and by 2.7 dB (95% CI[2.2, 3.2]) using an N95 mask. The 50%-listening effort signal-to-noise ratio was not significantly increased by 0.58 dB (95% CI[0.4, 1.5]) by a surgical mask but significantly increased by 2.2 dB (95% CI[1.2, 3.1]) using an N95 mask. In acoustic measures the amplitudes were reduced by the mask tissue by up to 8 dB at frequencies above 1 kHz while no reduction was observed below 1 kHz. We conclude that face masks reduce speech perception and increase listening effort in different noise signals. Together with an additional interference by missing lip reading the compound effect of face masks would have a relevant impact on daily life communication already in normal hearing subjects.

Social Settings

In social settings, speech waveforms from nearby speakers mix together in our ear canals. Normally, the brain unmixes the attended speech stream from the chorus of background speakers using a combination of fast temporal processing and cognitive active listening mechanisms. Of >100,000 patient records,~10% of adults visited our clinic because of reduced hearing, only to learn that their hearing was clinically normal and should not cause communication difficulties. We found that multi-talker speech intelligibility thresholds varied widely in normal hearing adults, but could be predicted from neural phase-locking to frequency modulation (FM) cues measured with ear canal EEG recordings. Combining neural temporal fine structure processing, pupil-indexed listening effort, and behavioral FM thresholds accounted for 78% of the variability in multi-talker speech intelligibility. The disordered bottom-up and top-down markers of poor multi-talker speech perception identified here could inform the design of next-generation clinical tests for hidden hearing disorders.

Purpose The original Connected Speech Test (CST; Cox et al., 1987) is a well-regarded and often utilized speech perception test. The aim of this study was to develop a new version of the CST using a neutral North American accent and to assess the use of this updated CST on participants with normal hearing. Method A female English speaker was recruited to read the original CST passages, which were recorded as the new CST stimuli. A study was designed to assess the newly recorded CST passages' equivalence and conduct normalization. The study included 19 Western University students (11 females and eight males) with normal hearing and with English as a first language. Results Raw scores for the 48 tested passages were converted to rationalized arcsine units, and average passage scores more than 1 rationalized arcsine unit standard deviation from the mean were excluded. The internal reliability of the 32 remaining passages was assessed, and the two-way random effects intraclass correlation was .944. Conclusion The aim of our study was to create new CST stimuli with a more general North American accent in order to minimize accent effects on the speech perception scores. The study resulted in 32 passages of equivalent difficulty for listeners with normal hearing.

Purpose The primary purpose of this study was to explore the audiovisual speech perception strategies.80.23.47 adopted by normal-hearing and deaf people in processing familiar and unfamiliar languages. Our primary hypothesis was that they would adopt different perception strategies due to different sensory experiences at an early age, limitations of the physical device, and the developmental gap of language, and others. Method Thirty normal-hearing adults and 33 prelingually deaf adults participated in the study. They were asked to perform judgment and listening tasks while watching videos of a Uygur–Mandarin bilingual speaker in a familiar language (Standard Chinese) or an unfamiliar language (Modern Uygur) while their eye movements were recorded by eye-tracking technology. Results Task had a slight influence on the distribution of selective attention, whereas subject and language had significant influences. To be specific, the normal-hearing and the d10eaf participants mainly gazed at the speaker's eyes and mouth, respectively, in the experiment; moreover, while the normal-hearing participants had to stare longer at the speaker's mouth when they confronted with the unfamiliar language Modern Uygur, the deaf participant did not change their attention allocation pattern when perceiving the two languages. Conclusions Normal-hearing and deaf adults adopt different audiovisual speech perception strategies: Normal-hearing adults mainly look at the eyes, and deaf adults mainly look at the mouth. Additionally, language and task can also modulate the speech perception strategy.
