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...

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...

Breeding for QPM ear rot resistant cultivars could offer a reliable environmental and economic control of mycotoxins especially for the resource-poor communities that require inexpensive protein diets. This research aims at evaluating a testcross of QPM inbreds with ear rot resistant cultivars to develop resistant topcrosses with high grain protein quality and yield. Seven QPM inbreds (lines) a...
