Final answer:
The appropriate dB level to obtain the word discrimination score in the word discrimination test (WDT) is the Speech Recognition Threshold (SRT).
Step-by-step explanation:
The appropriate dB level to obtain the word discrimination score in the word discrimination test (WDT) is B) SRT (Speech Recognition Threshold).
The Speech Recognition Threshold (SRT) is the lowest dB level at which the individual can correctly repeat 50% of the presented words. It measures the intensity level required for a person to recognize and repeat speech accurately.
For example, if the SRT is determined to be 40 dB, it means that the person can accurately understand and repeat 50% of the words when they are presented at a sound intensity level of 40 dB.
