Directional Hearing Aid Design
In this proposal we describe our intent to build a directional hearing aid under the guidance of Professor Erik Cheever and E. Carr Everbach. Currently, there is a need for reliable and effective hearing aid designs and we will attempt to implement one given our undergraduate background in engineering. This project will demonstrate our interdisciplinary education at Swarthmore College through t...
متن کاملInnovative mechanisms for directional hearing
Severe size constraints are imposed on the hearing organs of insects, yet they perform sophisticated tasks of auditory processing. Recent research has shown how flies acoustically locate targets in space, how mosquitoes afford highly sensitive ears, and how crickets avoid deafening themselves with their songs. These findings unveil the exquisite analytical capabilities of highly specialized mic...
متن کاملSingle-sided deafness and directional hearing: contribution of spectral cues and high-frequency hearing loss in the hearing ear
Direction-specific interactions of sound waves with the head, torso, and pinna provide unique spectral-shape cues that are used for the localization of sounds in the vertical plane, whereas horizontal sound localization is based primarily on the processing of binaural acoustic differences in arrival time (interaural time differences, or ITDs) and sound level (interaural level differences, or IL...
متن کاملAdvantages of Binaural Amplification to Acceptable Noise Level of Directional Hearing Aid Users
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 ...
متن کاملDirectional hearing in a silicon cricket
Phonotaxis is the ability to orient towards or away from sound sources. Crickets can locate conspecifics by phonotaxis to the calling (mating) song they produce, and can evade bats by negative phonotaxis from echolocation calls. The behaviour and underlying physiology have been studied in some depth, and the auditory system solves this complex problem in a unique manner. Experiments conducted o...
