Dear All,
Wish you all A VERY HAPPY & MERRY CHRISTMAS.I know that it would have been merrier if our exams. had been conducted on time. But trust me,inspite of the most sincere effort, we were not able to get an external examiner on time.Anyway, now that we have been able to finalize one, our exams are scheduled for December 28th and 29th,2012.So hopefully all of us will get to enjoy our New Year Eve without any stress and tensions with our near and dear ones.AMEN..
The other day after our revision class on X-Rays and Audiometry,I had promised Soumil that I will upload a presentation on ENT instruments in a VDO fromat.

Please peruse it and give me your feedback.

Audiograms...

Dear Friends,
As per our discussion yesterday, recapitulating for the benefit of all -
1) Audiology means.....Audire (L) means hear and logia (Gk) means the subject of study or discourse. So basically it means the science of study of hearing.
2) Audiometry means the measurement of or evaluation of hearing.
3) Broadly speaking ,Audiometry is divided into 2 types - Subjective and Objective.
    Subjective means where the (subjective) response of the patient is involved.
    Objective types obviate these subjective responses of the patient ...and hence are impervious to
    the personal wishes of the patient (read a ...relative immunity against malingering).
    Examples of Subjective Audiometry
    1) Pure Tone Audiometry

    2) Speech Audiometry

    3) Bekesy Audiometry   
    Examples of Objective Audiometry
    1) Impedance Audiometry

    2) BERA

    3) Oto Acoustic Emissions (OAE).

    Clinically the most relevant and informative type of Audiometry is Pure Tone Audiometry. The report is called as Pure Tone Audiogram.

A Typical Pure Tone Audiogram Chart

 It is Defined as "A Graphical Representation of the Hearing Acuity of the Patient qualitatively as well as quantitatively."
