According to the WHO world health organization, more than five percent of the world population needs rehabilitation for hearing loss, HL. Hearing loss is known to cause many negative health implications, including cognitive decline, and social isolation. The present study has been conducted to find out the impact of Bone anchored hearing aids, BAHA, on the Quality of Life in Adults, for this purpose, a systematic literature review was carried out among three databases, CINAHL, Pub Med, and Web of Science to identify the most relevant journal articles published over the last ten years between January 2012 till January 2022. There were seven studies selected based on inclusion and exclusion criteria. The study results were synthesized, and it was found that overall BAHA shows a positive impact on Quality-of-Life QoL among its users. It has been recommended that future research should be carried out with longitudinal studies and large study samples to establish the authenticated relationship between BAHA and its positive impact on Quality of Life

Virtual three-dimensional (3D) auditory displays utilize signal-processing techniques to alter sounds presented through headphones so that they seem to originate from specific spatial locations around the listener. In some circumstances bone-conduction headsets (bonephones) can provide an alternative sound presentation mechanism. However, existing 3D audio rendering algorithms need to be adjusted to use bonephones rather than headphones. This study provided anchor points for a function of shift values that could be used to adapt virtual 3D auditory displays for use with bonephones. The shift values were established by having participants adjust phase and amplitude of two waves in order to cancel out the signal and thus produce silence. These adjustments occurred in a listening environment consisting of air-conducted and bone-conducted tones, as well as air- conducted masking. Performance in the calibration condition suggested that participants understood the task, and could do this task with reasonable accuracy. In the bone-to-air listening conditions, the data produced a clear set of anchor points for an amplitude shift function. The data did not reveal, however, anchor points for a phase shift function the data for phase were highly variable and inconsistent. Application of shifts, as well as future research to establish full functions and better understand phase are discussed, in addition to validation and follow-up studies.
