Objectives: Sound field (SF) audiometry tests are usually conducted in audiometric booths measuring greater than 2×2 m in size. However, most private ENT clinics carry about 1×1-m-sized audiometric booths, making SF audiometry testing difficult to perform. The aims of this study were to develop an SF audiometry system for use in smaller audiometric booths and compare its performance with traditional system.
Methods: The newly developed SF audiometry system can yield an SF signal at a distance of about 30 cm from the subject's ears. Its height can be adjusted according to the subject's head height. We compared SF hearing results between the new SF system and the traditional SF audiometry system in 20 adults with normal hearing (40 ears) and 24 adults with impaired hearing levels (38 ears) who wore hearing aids. Comparative parameters included warble tone audiometry threshold, a speech reception threshold (SRT), and a speech discrimination score (SDS). For statistical analysis, paired t-test was used. The equivalence of both SF systems was tested using two one-sided test (TOST) with a margin of 5 dB (normal hearing participants) and 10 dB (hearing aids wearing participants).
Results: Among participants with normal hearing, warble tone hearing thresholds of 0.5, 1, 2, and 4 kHz, average values of these four frequencies, and SRT were similar between the two systems (all P>0.05). Participants with hearing aids showed similar warble tone threshold and SRT (P>0.05) in both systems except for threshold of 4 kHz (P=0.033). SDS was significantly higher in the newly developed system (P<0.05). TOST results showed equivalent SF audiometry results using either system.
Conclusion: Audiometric results of the newly developed SF audiometry system were equivalent to those of a traditional system. Therefore, the small SF audiometry system can be used at small audiometric booths present in most private ENT clinics.

Introduction: Despite the reported auditory deficits and developmental challenges in children with unilateral microtia and aural atresia (UMAA), there remains a lack of consensus on early intervention with bone conduction hearing aids (BCHAs) to restore binaural hearing due to the uncertain clinical benefits and intolerability of the conventional devices. Previous studies investigating the auditory benefits under binaural hearing condition were limited and demonstrated controversial opinions in heterogenous patient groups with various devices. Our study aimed to evaluate the audiological performance, including monoaural and binaural hearing, and subjective satisfaction of the ADHEAR system, a novel adhesive BCHA, in experienced pediatric users with UMAA.

Unlabelled: Central auditory disorders (CSD) - this is a violation of the processing of sound stimuli, including speech, above the cochlear nuclei of the brain stem, which is mainly manifested by difficulties in speech recognition, especially in noisy environments. Children with this pathology are more likely to have behavioral problems, impaired auditory, linguistic and cognitive development, and especially difficulties with learning at school.
Objective: To analyze the literature data on the epidemiology of central auditory disorders in school-age children.

Objectives: Valid wireless automated Békésy-like audiometry (ABA) outside a sound booth that includes extended high frequencies (EHF) would increase access to monitoring programs for individuals at risk for hearing loss, particularly those at risk for ototoxicity. The purpose of the study was to compare thresholds obtained with (1) manual audiometry using an Interacoustics Equinox and modified Hughson-Westlake 5 dB threshold technique to automated audiometry using the Wireless Automated Hearing Test System (WAHTS) and a Békésy-like 2 dB threshold technique inside a sound booth, and (2) ABA measured in the sound booth to ABA measured outside the sound booth.
Design: Cross-sectional study including 28 typically developing children and adolescents (mean = 14.

Background And Objectives: The immersive virtual reality (VR) simulator is advantageous because it is cost-effective, realistic, can be controlled directly by the user, and can be integrated into education and training in otorhinolaryngology. The present study explored the feasibility of incorporating VR pure-tone audiometry (PTA) into an audiologist training curriculum, and assessed audiology experts' willingness to use a VR PTA.
Materials And Methods: A total of 31 audiologists (16 skilled audiologists and 15 undergraduate students) participated in the study, using a developed VR PTA application with a Meta Quest 2 device.
