International Licensing Examination (ILE) Practice Test

At what intensity can a patient identify 50% of presented words according to the Speech Recognition Threshold?

1. The lowest intensity of hearing

2. The highest intensity before discomfort

3. The average speech intensity level

4. The intensity of background noise

The correct answer is: The lowest intensity of hearing

The correct answer is that the Speech Recognition Threshold (SRT) refers to the minimum intensity level at which a patient can accurately identify 50% of presented words. This threshold represents a critical point in audiology assessments as it helps clinicians determine the lowest level of speech that a patient can perceive reliably. In the context of the other options, the lowest intensity of hearing indicates the softest sound level that can be detected, which aligns with the definition of SRT. The highest intensity before discomfort, on the other hand, relates to loudness tolerance rather than the recognition of words. The average speech intensity level does not specify a minimum identification point and is instead a general reference for typical conversation levels. Lastly, the intensity of background noise is unrelated to a patient's ability to recognize speech as it pertains to external sound interference rather than the threshold of speech recognition itself. Thus, the correct understanding of SRT as the lowest intensity at which speech can be understood is well represented by the first choice.
