In a binaural hearing aid system, output signals for the left and the right ear are generated by exchanging information between the two hearing aids. A significant noise reduction can be achieved using the binaural multi-channel Wiener filter (MWF), which requires all microphone signals from both hearing aids. However, the limited bandwidth of the binaural link typically does not allow to trans...

Early binaural experience can recalibrate central auditory circuits that support spatial hearing. However, it is not known how binaural integration matures shortly after hearing onset or whether various developmental stages are differentially impacted by disruptions of normal binaural experience. Here we induce a brief, reversible unilateral conductive hearing loss (CHL) at several experimental...

In animals with bilaterally normal hearing, olivocochlear pathways can protect the cochlea from the temporary shifts in hearing sensitivity (temporary threshold shifts; TTSs) caused by short-duration intense loud sounds. The crossed olivocochlear pathway provides protection during binaural loud sound, and uncrossed pathways protect when monaural or binaural loud sounds occur in noise background...

OBJECTIVES The goal of the present study was to examine whether Acceptable Noise Levels (ANLs) would be lower (greater acceptance of noise) in binaural listening than in monaural listening condition and also whether meaningfulness of background speech noise would affect ANLs for directional microphone hearing aid users. In addition, any relationships between the individual binaural benefits on ...

background and aim: spatial hearing is one of the most important functions of binaural hearing processing that is based on detection of fine interaural time and interaural intensity difference. spatial hearing is beyond auditory localization and lateralization. it helps auditory scene analysis and target stream segregation from other simultaneous sound sources. this function is important in spe...

BACKGROUND Binaural hearing improves our ability to understand speech and to localize sounds. Hearing loss can interfere with binaural cues, and despite the success of amplification, ∼25% of people with bilateral hearing loss fit with two hearing aids choose to wear only one (e.g., Brooks and Bulmer, 1981). One explanation is reduced binaural processing, which occurs when the signal presented t...

The aim of the present study was to compare the benefit of monaural versus binaural ear-level frequency modulated (FM) fitting on speech perception in noise in children with normal hearing. Reception threshold for sentences (RTS) was measured in no-FM, monaural FM, and binaural FM conditions in 22 normally developing children with bilateral normal hearing, aged 8 to 9 years old. Data were gathe...

Normal-hearing persons can make use of two ears in daily listening, and this binaural hearing offers a lot of advantages compared to monaural hearing. The mechanisms of binaural hearing are based on an analysis of interaural differences and monaural cues that are due to directional dependent filtering of the outer ears as described by HeadTransfer Functions. In order to support the binaural abi...

Bilateral cochlear implants aim to provide hearing to both ears for children who are deaf and promote binaural/spatial hearing. Benefits are limited by mismatched devices and unilaterally-driven development which could compromise the normal integration of left and right ear input. We thus asked whether children hear a fused image (ie. 1 vs 2 sounds) from their bilateral implants and if this "bi...

elicited by each ear input up to auditory cortex. We recorded the auditory steady-state field in each hemisphere independently and evaluated the binaural interaction in normal-hearing subjects and patients with hearing impairment. In normal-hearing subjects ipsilateral input was suppressed more than contralateral input under binaural condition and there was no effect of sound intensity. In pati...
