1.	Pure-tone audiometers usually generate test tones in octave steps from___________(a) 125 to 800 Hz(b) 125 to 8000 Hz(c) 25 to 8000 Hz(d) 15 to 800 HzThis question was posed to me in an internship interview.The query is from Measurement of Hearing topic in division Audiometry of Biomedical Instrumentation
Answer» CORRECT option is (b) 125 to 8000 Hz The best I can explain: 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. Pure-tone audiometry is USED in routine tests and, therefore, it is the most widely used technique for determining hearing loss. Pure-tone audiometry has several advantages, which makes it specifically suitable for MAKING threshold SENSITIVITY measurements. A pure-tone is the simplest type of auditory stimulus. It can be specified accurately in terms of frequency and intensity.
