A series of behavioral experiments examined what cues listeners use to judge distance of nearby sources in reverberant spaces. Results show that, in real environments, reverberation aids performance even for sources within a meter of the listeners, where reverberant energy is relatively low compared to the direct sound. When simulating the same conditions using binaural head-related impulse res...

OBJECTIVE To evaluate the long-term results and predictive factors of a good outcome with the use of a total ossicular replacement prosthesis in children. DESIGN Retrospective case review. SETTING Tertiary referral center. PATIENTS The study included 114 children (116 ears). INTERVENTIONS A total of 116 ears underwent total ossicular chain reconstruction with a titanium prosthesis. Cart...

CONTEXT Endolymphatic sac tumors (ELSTs) are associated with von Hippel-Lindau disease and cause irreversible sensorineural hearing loss (SNHL) and vestibulopathy. The underlying mechanisms of audiovestibular morbidity remain unclear and optimal timing of treatment is not known. OBJECTIVE To define the mechanisms underlying audiovestibular pathophysiology associated with ELSTs. DESIGN, SETT...

Headphones-based spatial audio simulations rely on Head-related Transfer Functions (HRTFs) in order to reconstruct the sound field at entrance of listener’s ears. A HRTF is strongly dependent specific anatomical structures, and it has been shown that virtual sounds recreated with someone else’s result worse localisation accuracy, as well altering other subjective measures such externalisation r...

BACKGROUND AND PURPOSE Menière disease and idiopathic sudden sensorineural hearing loss can have overlapping clinical presentation and may have similar pathophysiology. Prior studies using postcontrast 3D-FLAIR MR imaging suggest abnormal blood-labyrinth barrier permeability in both conditions, but the 2 diseases have not been directly compared by using the same imaging techniques. We hypothesi...

OBJECTIVE To report the first successful study to date of in vivo electromechanical reshaping of ear cartilage in a rabbit model. METHODS Ears of New Zealand white rabbits were reshaped using percutaneous needle electrode electromechanical reshaping (5 V for 4 minutes) and were then bolstered for 4 weeks. Ten ears were treated, with 2 undergoing sham procedures and serving as controls. The tr...

CONCLUSION Three-dimensional cone beam computed tomography (3DCT) images revealed characteristic malformations of the membranous labyrinth of the inner ear in Meniere's disease (MD). The morphology of the membranous region between the vestibular cecum of the cochlea and the saccule of ears with MD was compared to that of healthy ears. The present study supports the hypothesis proposed earlier t...

OBJECTIVE To evaluate the prevalence of misdiagnosis of the hearing impaired children, in order to investigate the existence of Auditory Neuropathy Spectrum Disorder. METHODS Analytical, prospective study conducted with 15 participants (30 ears) aged 10-12 years, with bilateral sensorineural hearing loss, attending a Hearing Rehabilitation Center, accompanied by a multidisciplinary team with ...

This study investigated the effects of monaural versus binaural amplification upon the speech recognition scores (SRSs) of children with bilateral moderate sensorineural hearing loss after more than 4 years of hearing aid use. There was a significant decrease in SRSs for the unaided ears of the monaural hearing aid users, but there were no significant differences between initial and retest SRSs...
