The cochlea
Ears have evolved in parallel in vertebrates since a common divergence 300 million years ago. In birds, reptiles and amphibia, the hearing organ is strictly referred to as a papilla. The cochlea is the hearing organ of mammals and consists of a coiled cavity within the temporal bone on either side of the head. It contains the structures that separate the components of a complex sound by frequen...

این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
The Active Cochlea
The cochlea is a hydromechanical frequency analyzer located in the inner ear (Fig. 1 a). Its principal role is to perform a realtime spectral decomposition of the acoustic signal in producing a spatial frequency map. The frequency analysis may be understood with the aid of Figure 1 b, which shows a straightened cochlea with a snapshot of its basilar membrane displaced in response to a single-fr...
متن کاملOtoreflectance of the cochlea and middle ear.
Otoreflectance refers to acoustic pressure reflectance measurements in the ear canal, by the use of a leak-free insertion of a probe assembly, in the frequency or time domain over a range of two or more stimulus levels. Otoreflectance includes an iso-level response indicative of the forward transfer of acoustic energy into the middle ear, and nonlinear responses indicative of the acoustic energ...
