International Licensing Examination (ILE) Practice Test

What is a biological check in the context of audiometry?

1. Testing for environmental noise levels

2. Verifying the audiometer's function

3. Measuring sound intensity in the ear

4. Assessing patient hearing response

The correct answer is: Verifying the audiometer's function

In the context of audiometry, a biological check refers specifically to the process of verifying the performance and accuracy of an audiometer. This involves using test subjects, typically individuals with known hearing thresholds, to ensure that the equipment is functioning correctly and providing reliable results. The aim is to confirm that the audiometer's calibration is accurate and that it is producing the correct sound levels for various frequency ranges. Conducting regular biological checks is essential for maintaining the integrity of hearing evaluations and ensuring that the results can be trusted. Testing for environmental noise levels, measuring sound intensity in the ear, and assessing patient hearing response are all significant components of audiological assessments. However, these do not directly pertain to the verification process of the audiometer itself, which is the primary focus of a biological check.
