ASLP NOTES

The stimulation is transmitted to the cochlear fluids by the in and out motion of the Stapedius-footplate at the oval window at the base of the Cochlea.  The oval window leads into the upper chamber (Scala vestibuli) hence given inward motion will cause the fluids to be displaced downward ,Pushing downward on the Basilar membrane and a given outward motion will  displaced the fluid and basilar membrane upward.  The trick is to translate this vibratory stimulation into the bending of the hair cell Stereocilia in the right direction and it will activates the sensory process . There are some theories which explain the sensorineural mechanism of vestibular system called the Theories of hearing it is of two types  1. Traditional Theory The Traditional theories of hearing further divided in to three types i. Resonance place theory                                    ...

The sound signal that reach to the ear drum in the form of air vibration must be transmitted to the cochlea which is a fluid filled system'  The impedance of cochlear fluids are much greater then the impedance of air: Most of the sound energy reflected back  only about 0.1% of the energy transmitted to the cochlea and 99.9% if the energy is reflected back The middle ear overcome this impedance mismatch by acting as a mechanical transformer that boost the signal so that energy can be effectively transmitted to the cochlea There are three mechanism which are used to overcome the transformer action of middle ear 1-Area ratio of Ear drum to Oval window 2-Curved membrane buckling effect of the tympanic membrane 3- Lever action of the ossicular chain 1. The Ratio of Ear drum to Oval window The largest contributions comes from Area advantages' The Area of tympanic membrane larger than the Area of Oval window , The force that us exerted over the larger area of tympanic membrane i...

AUDIOLOGY:-                                             Audiology  means Audio stand for Hearing and Logy stand for study  means Audiology is the science of hearing or study of Hearing OR Audiology is the clinical profession that deal with hearing and balance disorder OR  Audiology is the scientific study of normal and abnormal audition and related Area in the broadest sense.                           AUDIOLOGIST:-                               Audiologist is a practitioner of Audiology As a clinical  profession  'Audiologists are principally concerned with the Identification' Evaluation' and Management or patients with auditory and balance disorders As well As with prevention of hearing impairment .Th...

BASLP stand for Bachelor of Audiology and Speech Language Pathology  It is Undergraduate course which comes under Rehabilitation Council of India (RCI).                  The BASLP course deal the Assessment of hearing impaired individuals and Speech 'Language and voice Related problem.                         ELIGIBILITY                                                   In BASLP Course the minimum eligibility criteria for take the admission  Is 10+2 With Science stream  with 50% and 45% for SC and ST student. Some university take admission on the basis of entrance examination and Some university take direct admission on the basis of 10+2 percentage                         ...
