Five different pathways are often suggested as important for bone conducted (BC) sound: (1) sound pressure in the ear canal, (2) inertia of the middle ear ossicles, (3) inertia of the inner ear fluid, (4) compression of the inner ear space, and (5) pressure transmission from the skull interior. The relative importance of these pathways was investigated with an acoustic-impedance model of the in...

OBJECTIVES To describe middle ear ventilation route blockage, relieved during middle ear endoscopic surgery, and to analyze its association with mastoid hypopneumatization/sclerotization. STUDY DESIGN Prospective case series with intraoperative analyses, and with a case-control computed tomographic scan comparison. METHODS Intraoperative findings during endoscopic middle ear surgery are des...

background and aim: hearing impaired students experience binaural hearing like normal peers and school age is challenging time for using dichotic listening. lack of research was found on relationship of persian hearing impair­ed children with central auditory processing (cap). one of the aims of this study was a comparison between persian dichotic digit test (ddt) score in children with mild an...

JCB • VOLUME 211 • NUMBER 5 • 2015 938 Growing up in Chile, Marcos Sotomayor was always interested in how things worked, and fascinated by his architect father’s technical drawings of buildings and his artist mother’s ability to create colorful sculptures. He also held an early interest in computers. Although he begged his parents for an Atari® game system like his friends had, they instead sav...

In order to improve the recognition rate of ear, a novel ear recognition algorithm is proposed based on improved locally linear embedding algorithm. Firstly, the ear features are extracted by Gabor transform, and then the improved LLE is used to reduce dimensionality of features and select the optimal features of ear recognition, finally support vector machine is used to establish the classifie...
