What is an example of a supra-threshold measure in speech testing?

A supra-threshold measure in speech testing refers to the assessment of an individual's ability to understand speech at a volume level above their threshold of hearing. The word recognition score (WRS) is a prime example of this type of measure, as it evaluates how well a person can identify and repeat back words presented at a specific intensity level that is comfortably above their hearing threshold.

In contrast, measures like speech recognition threshold (SRT) focus on determining the lowest level at which a person can recognize speech 50% of the time, which is a threshold measure rather than a supra-threshold one. Similarly, hearing threshold level (HTL) pertains to the lowest level of sound that an individual can hear but does not directly evaluate speech recognition abilities. Hearing screening tests typically assess whether a hearing loss is present without necessarily focusing on the individual's ability to understand speech at various intensity levels.

Understanding these distinctions is crucial in audiology and speech-language pathology, as they inform the evaluation and management of individuals with hearing disorders across different stages of life.
