**2. Audiologic evaluation technology**

Several subjective and objective methods to assess hearing disorders are available, depending on the individual's age, hearing level and condition type. Among other things, evaluation must be conducted for cochlear integrity, acoustic impedance, and screening of hearing of newborns and infants.

With ever changing technology and new methodologies in healthcare, available for addressing the specific needs of adult and pediatric populations, hearing technology represents not only devices for clinicians' practice, but also devices to meet the high level of need for diagnostic techniques, audiologic rehabilitation, treatment methodologies, and special issues in researching the needs of patients (Montano & Spitzer, 2009).
