What is the main purpose of a Speech Reception Threshold (SRT) test?

The primary purpose of a Speech Reception Threshold (SRT) test is to determine a patient's ability to recognize and comprehend speech, specifically the lowest level at which they can accurately repeat back words presented to them. This test typically involves the use of spondee words—two syllable words with equal stress—allowing the audiologist to assess the threshold at which speech can be detected and understood.

Establishing this threshold is essential for diagnosing hearing loss and planning appropriate audiological management. The SRT provides valuable information that can be used alongside pure tone audiometry results to gain a comprehensive view of a patient's auditory capabilities, particularly in real-world communication scenarios.

In contrast, other options refer to different auditory functions and capabilities. Auditory processing capabilities focus more on how the brain interprets auditory information rather than simply understanding speech level. Validating pure tone thresholds relates to confirming results obtained through traditional audiometry testing, rather than focusing specifically on speech recognition. Measuring sound localization evaluates the ability to determine the origin of a sound in space, which falls outside the scope of what the SRT aims to assess.
