The performance of binaural processing may be disturbed in the presence of hearing loss, especially of sensorineural type. To assess the impact of hearing loss on speech perception in noise regarding binaural processing, series of speech recognition measurements in controlled laboratory conditions were carried out. The spatial conditions were simulated using dummy head recordings played back on headphones. The Intelligibility Level Difference (ILD) was determined by measuring the change in the speech reception thresholds (SRT) between two configurations of a masking signal source (N) and a speech source (S), namely the S0N90 condition (where numbers stand for angles in horizontal plane) and the co-located condition (S0N0). To disentangle the head shadow effect (better ear effect) from binaural processing in the brain, the difference between binaural and monaural S0N90 condition (so-called Binaural Intelligibility Level Difference, BILD) value was calculated. Measurements were performed with a control group of normal-hearing listeners and a group of sensorineural hearing-impaired subjects. In all conditions performance of the hearing-impaired listeners was significantly lower than normal-hearing ones, resulting in higher SRT values (3 dB difference in the S0N0 configuration, 7.6 dB in S0N90 and 5 dB in monaural S0N90). The SRT improvement due to the spatial separation of target and masking signal (ILD) was also higher in the control group (8.1 dB) than in hearing-impaired listeners (3.5 dB). Moreover, a significant deterioration of the binaural processing described by BILD was found in people with sensorineural deficits. This parameter for normal-hearing listeners reached a value of 3 to 6 dB (4.6 dB on average) and decreased more than two times in the hearing-impaired group to 1.9 dB on average (with a deviation of 1.4 dB). These findings could not be explained by individual average hearing threshold (standard in audiological diagnostics) only. The outcomes indicate that there is a contribution of suprathershold deficits and it may be useful to consider binaural SRT measurements in noise in addition to the pure tone audiometry resulting in better diagnostics and hearing aid fitting.

Objectives The aim of the study was to investigate whether a ski helmet interferes with the sound localization and the time of sound perception in the frontal plane. Material and Methods Twenty-three participants (age 30.7±10.2) were tested on the slope in 2 conditions, with and without wearing the ski helmet, by 6 different spatially distributed sound stimuli per each condition. Each of the subjects had to react when hearing the sound as soon as possible and to signalize the correct side of the sound arrival. Results The results showed a significant difference in the ability to localize the specific ski sounds; 72.5±15.6% of correct answers without a helmet vs. 61.3±16.2% with a helmet (p < 0.01). However, the performance on this test did not depend on whether they were used to wearing a helmet (p = 0.89). In identifying the timing, at which the sound was firstly perceived, the results were also in favor of the subjects not wearing a helmet. The subjects reported hearing the ski sound clues at 73.4±5.56 m without a helmet vs. 60.29±6.34 m with a helmet (p < 0.001). In that case the results did depend on previously used helmets (p < 0.05), meaning that that regular usage of helmets might help to diminish the attenuation of the sound identification that occurs because of the helmets. Conclusions Ski helmets might limit the ability of a skier to localize the direction of the sounds of danger and might interfere with the moment, in which the sound is firstly heard.

The justifiability of the institution of the hearing in administrative proceedings may raise some doubts. The paper explores how this element of proceedings operates from the angle of speedy proceedings, the principle of objective truth as well as purposes which the administrative proceedings as such serve. The author puts forward a thesis that the hearing is not a necessary element of administrative proceedings; moreover, it could be excluded therefrom without affecting the proceedings in a negative manner. In fact, this could even contribute to the fulfilment of the principle of speedy proceedings, as well as depoliticize some proceedings or at least reduce the media interest in them. The paper presents a review of relevant case-law regarding hearings in administrative proceedings. Also, arguments for and against maintaining the hearing have been analyzed. The arguments against it include the need for speedy proceedings, limited credibility of witness evidence or general limited justifiability of holding hearings. In turn, arguments for the institution in question encompass especially the opportunity to collect evidence at the same time and at the same place, as well as the possibility to conduct confrontation. The discussion part of the paper includes de lege ferenda conclusions concerning the possibility to eliminate the hearing from administrative proceedings. This reflects the fundamental thesis of the paper as well as the doubts arising from case-law and practice of decision-making bodies as to whether keeping the institution of the hearing is justifiable.

Directive 2003/10/EC sets the requirement for evaluating the effect of noise on accident risk. Accident risk is elevated for workers with a hearing handicap because of their reduced speech intelligibility and reduced capability to perceive the direction of incoming sound. An audiogram is not a good method for the evaluation of these functions. To reduce accident risk, organisational and personal solutions are needed. For both methods, efficiency must be evaluated through proper risk assessment. Because practical guidelines are not available, this paper presents principles for accident risk evaluation techniques.

The overall purpose of this study was to assess hearing status in professional orchestral musicians. Standard pure-tone audiometry (PTA) and transient-evoked otoacoustic emissions (TEOAEs) were per- formed in 126 orchestral musicians. Occupational and non-occupational risk factors for noise-induced hearing loss (NIHL) were identified in questionnaire inquiry. Data on sound pressure levels produced by various groups of instruments were also collected and analyzed. Measured hearing threshold levels (HTLs) were compared with the theoretical predictions calculated according to ISO 1999 (1990). Musicians were exposed to excessive sound at weekly noise exposure levels of for 81-100 dB (mean: 86.6±4.0 dB) for 5-48 years (mean: 24.0±10.7 years). Most of them (95%) had hearing corresponds to grade 0 of hearing impairment (mean hearing threshold level at 500, 1000, 2000 and 4000 Hz lower than 25 dB). However, high frequency notched audiograms typical for noise-induced hearing loss were found in 35% of cases. Simultaneously, about 35% of audiograms showed typical for NIHL high frequency notches (mainly occurring at 6000 Hz). When analyzing the impact of age, gender and noise exposure on hearing test results both PTA and TEOAE consistently showed better hearing in females vs. males, younger vs. older musicians. But higher exposure to orchestral noise was not associated with poorer hearing tests results. The musician’s audiometric hearing threshold levels were poorer than equivalent non-noise-exposed population and better (at 3000 and 4000 Hz) than expected for noise-exposed population according to ISO 1999 (1990). Thus, music impairs hearing of orchestral musicians, but less than expected from noise exposure.

The majority of children with hearing loss, thanks to screening programs, early fitting with hearing aids, and early therapeutic interventions, develop speech well enough to attend preschool along with their hearing peers. These preschool programs often take place in adverse acoustic conditions. In a study conducted on 25 children with hearing impairments aged 3 to 8 years (mean 5.9) – cochlear implant users – the therapeutic and educational effectiveness of the use of an additional hearing assistive device (mini wireless microphone) was tested. The results obtained confirmed the positive impact of the use of the device in additionally aiding hearing abilities in the areas of response to sound, sound localization, and quality of hearing.

Different studies have demonstrated that solvents may induce auditory damage. It has been suggested that part of this damage may be localised in central auditory pathways. The present study aimed to investigate possible auditory processing disorders related to solvent exposure. Thirty solvent-exposed workers and 30 gender-, age- and educational level-matched control subjects were selected to participate in the study. To select participants, a questionnaire, otoscopy, pure-tone audiometry and tympanometry were carried out. Filtered speech (FS), random gap detection (RGD) and hearing-in-noise tests (HINT) were conducted in the selected participants. Both groups of workers presented as a mean normal hearing thresholds. However, significant differences between groups were observed for RGD, FS and HINT. It is concluded that a possible auditory processing disorder may be related to solvent exposure.

The main objective of supporting the development of children with hearing loss is to optimize the process of acquiring and developing their linguistic competence and communication, despite the existing restrictions in this regard. This task is particularly important in relation to children with hearing parents, because their case involves the removal of barriers to communication between a child with a hearing impairment and his dearest and nearest. Opposite this objective comes out a number of methods, so-called auditory-verbal communication. The purpose of this article is to analyze the use of bilingualism of early support development of deaf children as the most popular model used in the United States. In this country, in which deaf people have won the right to betreated as a cultural minority rather than the disabled, a child with hearing loss has a suitable status predisposed to bilingualism, which entails the need to include it in the interactions supporting the development, discussed in the article.

Słuch jest zmysłem pozwalającym na odbieranie fal dźwiękowych. Narządem słuchowym są uszy. Coraz częściej człowiek spotyka się z ubytkiem słuchu. Historia zastosowania pierwszych urządzeń wspomagających słyszenie sięga aż starożytności. Zaczęto używać metalowe tuby. Wynalezienie mikrofonu, wzmacniaczy i tranzystorów spowodowało szybki postęp w rozwoju i miniaturyzacji aparatów słuchowych. Dzisiejsze aparaty słuchowe są dostosowywane do każdego pacjenta indywidualnie. Możemy wyróżnić aparaty słuchowe zauszne typu BTE i typu RITE, a także aparaty wewnątrzuszne ITE i wewnątrzkanałowe CIC.

Purpose: The potential demand for hearing aids is increasing in accordance with aging of populations in many developed countries. Because certain patients cannot use air conduction hearing aids, they usually use bone conduction hearing aids. However, bone does not transmit sound as efficiently as air, and bone conduction hearing aids require surgery (bone anchored hearing aid) or great pressure to the skull. The first purpose of this study is to examine the efficacy of a new sound conduction pathway via the cartilage. The second purpose is to develop a hearing aid with a cartilage conduction transducer for patients who cannot use regular air conduction hearing aids. Design/methodology/approach: We examined the hearing ability of a patient with atresia of both external auditory meatuses via three kinds of conduction pathways (air, bone, and cartilage). After the best position for the cartilage conduction transducer was found, audiometric evaluation was performed for his left ear with an insertion earphone (air conduction), a bone conduction transducer, and a cartilage conduction transducer. Then we made a new hearing aid using cartilage conduction and got subjective data from the patients. Findings: The tragal cartilage was the best position for the cartilage conduction transducer. The patient’s mean hearing levels were 58.3 dBHL, 6.7 dBHL, and 3.3 dBHL for air conduction, bone conduction, and cartilage conduction respectively. The hearing ability of the patients obtained from the cartilage conduction hearing aid was comparable to those from the bone conduction hearing aid. Practical implications: Hearing levels using cartilage conduction are very similar to those via bone conduction. Cartilage conduction hearing aids may overcome the practical disadvantages of bone conduction hearing aids such as pain and the need for surgery. Originality/value: We have clarified the efficacy of the cartilage conduction pathway and developed a prototype ‘cartilage conduction hearing aid’, which is the first hearing aid to use sound transmission via cartilage.

Quality of life of the elderly is an important social problem due to demographic changes associated with lengthening life expectancy. With age, numerous health problems tend to appear, most commonly vision and hearing defects. A consequence of age-related hearing loss is difficulty associated with communication capabilities. This in turn affects quality of life, relations with loved ones, and the effectiveness of social contacts. The aim of the survey, conducted among 116 people aged over 60 years old, was an attempt to analyse the relationship between communications capabilities (using the SAC self-assessment questionnaire) and quality of life (the WHOQOL-BREF questionnaire). The results established that the quality of life of older adults stood at an average level, while their auditory capabilities were described as good. The higher the assessment of health, activity and physical fitness, the higher the quality of life and this was also associated with slightly better capabilities of communicating with their surroundings. Lower quality of life in the areas of physical health, social relations, scope of communication, were declared by respondents from the group over 70 years of age. Men slightly more often than women indicated worse communication capabilities. No correlation was found between the quality of life of the respondents and self-assessment of their communication capabilities. There is a need solutions to support preventive physical activity in groups of older adults and younger people which would affect quality of life, and can contribute to improving the quality of communication, among others, by broadening the network of interpersonal contacts.

Jakość życia osób starszych jest ważnym problemem społecznym ze względu na zmiany demograficzne związane z wydłużaniem się średniej długości życia. Wraz z wiekiem pojawiają się liczne problemy zdrowotne, najczęściej wady wzroku i słuchu. Konsekwencja niedosłuchu uwarunkowanego wiekiem są trudności związane z możliwościami komunikacyjnymi. To z kolei wpływa na jakość życia, relacje z bliskimi, efektywność kontaktów społecznych. Celem badania, przeprowadzonego wśród 116 osób w wieku powyżej 60 lat – mieszkańców Polski południowo-wschodniej – była próba analizy zależności między możliwościami komunikacyjnymi (określono za pomocą kwestionariusza samooceny SAC) a jakością życia (kwestionariusz WHOQOL-BREF). Na podstawie uzyskanych wyników stwierdzono, że jakość życia starszych osób dorosłych kształtuje się na poziomie przeciętnym, a ich możliwości słuchowe określane są jako dobre. Im wyższa ocena zdrowia, aktywności i sprawności fizycznej, tym wyższa jakość życia, co wiązało się również z nieco lepszymi możliwościami komunikowania się z otoczeniem. Niższą jakość życia w zakresie zdrowia fizycznego, relacji społecznych, zakresu komunikacji, deklarowali respondenci z grupy żej 70. roku życia. Mężczyźni nieco częściej niż kobiety wskazywali na gorsze możliwości komunikacyjne. Nie stwierdzono zależności między jakością życia badanych a samooceną ich możliwości komunikacyjnych. Istnieje potrzeba wprowadzenia rozwiązań wspierających profilaktyczną aktywność fizyczną w grupach starszych dorosłych i młodszych, która wpłynęłaby na jakość życia, a także mogłaby przyczynić się do poprawy jakości komunikacji, m.in. poprzez poszerzenie sieci kontaktów interpersonalnych.
