Which of the following is NOT an example of a subjective measurement in audiology?

Hearing thresholds through pure tone testing is an objective measurement in audiology. This testing involves the use of calibrated equipment to determine the faintest sounds a person can hear at various frequencies, which produces quantifiable results that can be recorded and analyzed. These measurements do not rely on the patient's perception or opinion; they are based on the physical response of the auditory system to sound stimuli.

In contrast, patient-reported hearing difficulties, speech intelligibility ratings, and self-reported quality of life assessments are all subjective measures. They depend on the individual's perceptions and experiences regarding their hearing or communication abilities and overall well-being. Subjective measures, while valuable for understanding a patient's personal challenges and experiences, do not provide the objective data that pure tone testing offers.
