Although many researchers have shown that listeners are able to selectively attend to a target speech signal when a masking talker is present in the same ear as the target speech or when a masking talker is present in a different ear than the target speech, little is known about selective auditory attention in tasks with a target talker in one ear and independent masking talkers in both ears at...
The human ear is a new class of relatively stable biometrics. After decades of research of anthropometric measurements of ear photographs of thousands of people, it has been found that no two ears are alike, even in the cases of identical and fraternal twins, triplets, and quadruplets [1]. It is also found that the structure of the ear does not change radically over time. Ear biometric has play...
BACKGROUND Prominent ear is the most common congenital ear deformity affecting 5% of children in the Western world and has profound psychosocial effects on the bearer. It is important to know the prevalence in the local population to have a better appreciation of the local burden of the abnormality as well as to know the parameters of ear morphology locally. These parameters can be useful in th...
We present a practical approach to capturing ear-to-ear face models comprising both 3D meshes and intrinsic textures (i.e. diffuse and specular albedo). Our approach is a hybrid of geometric and photometric methods and requires no geometric calibration. Photometric measurements made in a lightstage are used to estimate view dependent high resolution normal maps. We overcome the problem of havin...

Introduction:One of the recommended methods for evaluation effectiveness of hearing protection is use the acoustic fixture accordance with standard ISO 4869-3. The aim of this study was evaluate the acoustic performance of fixture for using in noise reduction rate tests of hearing protection devices in the laboratory. Methods: In this cross-sectional study , noise reduction rates o...
Objectives: Real ear measurement plays a critical role in children’s hearing aid fitting. This study aimed to evaluate the conformity of measured and predicted real-ear aided response (REAR) of prescribed formula desired sensation level (DSL) v5 Pediatric in children aged 4 to 7 years. Since there is limited information about the effect of the degree of hearing loss (DOHL), ethnicity, gender, a...
otodectes cynotis , ear mite or ear canker mite, is the most common cause of otitis externa in cats (approximately 50%) and to a lesser extent in dogs, foxes and ferrets. the mite is living on the epidermal surface of auditory canal without burrowing into the tissueand feeding on tissue fluids and debris. in most of the cases they induce hypersensitivity reactions in the host. four puppies; si...
objective: generated acoustic trauma by suction and drill may cause sensorineural hearing loss after tympanomastoid surgery. this study was carried out to determine the relationship of sensorineural hearing loss and chronic otitis media surgery at ahvaz jundishapur university of medical sciences in iran. material and methods: this prospective study included 386 patients of chronic middle ear di...
Introduction: Otalgia is one of the complaints which may occur at any age. The etiology of the pain may be in the ear, structures around the ear or other head and neck structures. This is caused by the complex nervous connections in the head and neck areas, the ear, the pharynx and the nose. Since understanding the etiologies of referred otalgia can help in the assessment and treatment of the ...
