The Directional Effects of Marker Frequencies on Across-Channel Temporal Gap Detection Tasks: An Experimental Study.

Introduction: Gap detection tests are crucial clinical tools for identifying auditory processing disorders that result from abnormalities in the central auditory nervous system. These tests assess the ability to resolve temporal information in sounds, which aids in the diagnosis of auditory temporal processing issues. This study explores the directional effects of marker frequencies on gap detection tasks with respect to the conditions of long and short frequency disparity (separation).

Across- and Within-Channel Gap Detection Thresholds Yielded by Two Different Test Applications.

Background: Individuals with auditory processing disorders show some deficits with the temporal processing of auditory signals. Gap detection measurements are commonly used to assess temporal processing skills across different listening tasks.

Purpose: The aim of this study was to compare the gap detection thresholds (GDTs) in across-channel (AC) and within-channel (WC) tasks by using two computer applications-Adaptive Tests of Temporal Resolution (ATTR) and Psycon.

Auditory temporal resolution in adaptive tasks. Gap detection investigation.

To study auditory temporal resolution skills using adaptive auditory tasks designed with a computer-based experimental program, and to provide normative valuesfor gap detection thresholds (GDTs) of young listeners in 3 listening conditions. Methods:  The GDTs were established under 3 stimulus conditions: 1) broadband noise (BBN), 2) narrowband noise within-channel (NBN WC) using similar leading and trailing markers centered at 1.0 KHz, and 3) narrowband noise across-channel (NBN AC) with the leading marker centered at 2.

Efficacy of Directional Microphones in Hearing Aids Equipped with Wireless Synchronization Technology.

Objective: This study aimed to evaluate the use of directionality in hearing aids with wireless synchronization on localization and speech intelligibility in noise.

Materials And Methods: This study included 25 individuals with bilateral mild to moderate flat sensorineural hearing loss. For the localization experiment, eight loudspeakers (Genelec 8020B) arranged in a circle covering a 0-360° angle and the Cubase 6 software were used for presenting the stimulus.

Development of equally intelligible Telugu sentence-lists to test speech recognition in noise.

Objective: To develop sentence lists in the Telugu language for the assessment of speech recognition threshold (SRT) in the presence of background noise through identification of the mean signal-to-noise ratio required to attain a 50% sentence recognition score (SRTn).

Design: This study was conducted in three phases. The first phase involved the selection and recording of Telugu sentences.
