The binaural masking level difference (BMLD) is a psychoacoustic method to determine binaural interaction and central auditory processes. The BMLD is the difference in hearing thresholds in homophasic and antiphasic conditions. The duration, phase and frequency of the stimuli can affect the BMLD. The main aim of the study is to evaluate the BMLD for stimuli of different durations and frequencies which could also be used in future electrophysiological studies. To this end we developed a GUI to present different frequency signals of variable duration and determine the BMLD. Three different durations and five different frequencies are explored. The results of the study confirm that the hearing threshold for the antiphasic condition is lower than the hearing threshold for the homophasic condition and that differences are significant for signals of 18ms and 48ms duration. Future objective binaural processing studies will be based on 18ms and 48ms stimuli with the same frequencies as used in the current study.

Objectives: This study compared a simplified in situ self-administered hearing screening test, conducted with a neckband-type self-fitting device, with conventional pure-tone audiometry. It evaluated the maximum speech-shaped noise level for screening (MSNLS), crucial for evaluating the feasibility of this in situ screening test in quiet environments.
Methods: This study included 30 adults with normal hearing and 30 adults with mild to moderately severe hearing impairment.

Extended high-frequency (EHF) hearing loss offers a model for investigating the onset of auditory dysfunction before changes in standard audiometric thresholds occur. However, the impact on auditory perception remains poorly understood. This study evaluated the relationship between EHF hearing sensitivity and monaural and binaural measures of auditory temporal resolution and spatial release from masking in young adults (aged 20-35 years) with normal hearing thresholds in the clinical frequency range (.

Objective: Vestibular evoked myogenic potential (VEMP) can be elicited using bone-conducted vibration (BCV) and air-conducted sound, with BCV VEMP typically associated with bilateral vestibular pathways. We employed a new acoustic masking method to obscure BCV VEMP, aiming to explore the feasibility of unilateral BCV VEMP testing.
Materials And Methods: Twenty healthy adults (20-37 years old; 10 males and 10 females) participated in the study.
Magnified interaural level differences enhance binaural unmasking in bilateral cochlear implant users.

Bilateral cochlear implant (BiCI) usage makes binaural benefits a possibility for implant users. Yet for BiCI users, limited access to interaural time difference (ITD) cues and reduced saliency of interaural level difference (ILD) cues restricts perceptual benefits of spatially separating a target from masker sounds. The present study explored whether magnifying ILD cues improves intelligibility of masked speech for BiCI listeners in a "symmetrical-masker" configuration, which ensures that neither ear benefits from a long-term positive target-to-masker ratio (TMR) due to naturally occurring ILD cues.

Binaural beats (BBs) have garnered attention as a highly accessible, noninvasive method to enhance cognitive performance, putatively via brain entrainment. However, the few studies that have directly examined the impact of BBs on sustained attention report inconsistent findings, perhaps due to wide variation in methodology. This study experimentally varied BB parameters while testing the effects of BBs on both sustained attention and brain entrainment.
