What indicates the softest intensity that words can be repeated with 50% accuracy in WRS?

The correct choice relates to the concept of the percent-correct score, which is a measurement used in word recognition testing (WRS). This score represents the softest intensity level at which a patient can correctly repeat words or phrases with a given level of accuracy—in this case, 50%.

In hearing assessments, the percentage indicates how well a patient can understand and recognize spoken words when they are presented at various intensities. This measure is crucial because it informs audiologists and hearing aid specialists about the effectiveness of a hearing aid or hearing capacities of an individual. When the intensity is adjusted and the words are tested, reaching a score of 50% correct means the patient can hear and understand half of the words presented at that specific loudness level.

While the other options also relate to aspects of hearing assessments, they do not directly indicate the level of word recognition accuracy at a specific intensity. Spondees are a type of word used in testing but do not reflect the 50% accuracy specifically for word recognition scores. Presentation intensity refers to the loudness at which words are played but does not inherently convey how well a patient is able to recognize those words.
