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 ...

Introduction:Noise in dental offices is one of the risk factors in the workplace. One of the major effects of noise is hearing loss. This study aimed to determine the effects of noise on hearing thresholds of dentists of Babol city. Methods:This descriptive analytical cross-sectional study was performed on 40 dentists in Babol City (as case group) and 40 office workers (as control group). He...

Reported here is a technique for measuring forward and reverse middle-ear transmission that exploits distortion-product otoacoustic emissions (DPOAEs) to drive the middle ear "in reverse" without opening the inner ear. The technique allows measurement of DPOAEs, middle-ear input impedance, and forward and reverse middle-ear transfer functions in the same animal. Intermodulation distortion in th...

The objective of this work was evaluating the nitrogen fertilization splitting on performance green corn, grown in rainfed system. experiment carried out Forquilha, Ceará state. Two varieties corn (Sweet and Gorutuba) were used experiment, five types crop cycle (one; three; six; nine twelve applications). variables evaluated were: plant height, stem diameter, number leaves plant, fresh mass, dr...

The paper focuses on the loads applied to helicopter blade cross-sections in multibody dynamics system. main objective is simplify aerodynamics calculation and avoid time-consuming CFD methods. For this reason, way of computing proposed by using methods with a linear-elastic model. As primary tool for further research, MCS Adams software package selected. Splitting rotor into finite number sect...
