Right choice is (a) True

To elaborate: It is True. The frequency range of pure-tone audiometer is more than that of speech audiometer. Pure-tone audiometers usually generate test tones in octave steps from 125 to 8000 Hz, the signal intensity ranging from –10 dB to +100 dB. Speech audiometry normally allows measurements to be made within the frequency range of 300–3000 Hz. Pure-tone audiometry has several advantages, which makes it specifically suitable for making threshold sensitivity measurements.
