Ear is sensitive to: (A) 500-3500 HZ, (B) 1000-3000 HZ, (C) 300-5000 HZ, (D) 5000-8000 HZ
Answer is A. External auditory canal 3000 Hz Tympanic membrane 800-1600 Hz Middle ear 800 Hz Ossicular chain 500-2000 Hz Thus the greatest sensitivity of sound transmission is between 500- 3000 Hz Ref: Dhingra 7e pg 17.
