Impedance Audiometry

Evaluation of pure tone audiometry and impedance screening in infant schoolchildren.

STUDY OBJECTIVE The aims were (1) to evaluate impedance measurements against pure tone audiometry as a screening method for the detection of middle ear changes associated with hearing loss in infant school children; (2) to estimate the costs of the health authority of each method. DESIGN The study involved two stage screening in which both methods were offered, pure tone audiometry being carr...

In-situ audiometry: How close is it to conventional audiometry?

Technology in the hearing aid industry is ever changing. One of the many features that may improve accuracy of hearing aid fi ttings and patients ’ satisfaction is the inception of in-situ audiometry, which allows the clinician to measure hearing thresholds with a hearing aid in the patient ’ s ear. Objective : The present study aimed to investigate the validity of in-situ audiometry measured w...

In-situ audiometry

Audiometry screening and interpretation.

The prevalence of hearing loss varies with age, affecting at least 25 percent of patients older than 50 years and more than 50 percent of those older than 80 years. Adolescents and young adults represent groups in which the prevalence of hearing loss is increasing and may therefore benefit from screening. If offered, screening can be performed periodically by asking the patient or family if the...

Pure Tone Audiometry

Pure tone audiometry is the standard behavioral assessment of an individual’s hearing. The results of pure tone audiometry are recorded on a chart or form called an audiogram. In most cases a pure tone audiogram is easy to obtain and provides information about peripheral hearing acuity across the frequencies used in speech. It allows for a quick view of how well, or how poorly, an individual ca...
