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."
