What hearing levels are considered normal on an audiogram?

• A. Below 30 dB
• B. Within the range of 0-20 dB
• C. Above 30 dB
• D. Above 60 dB

Answer: (B)

Normal hearing levels on an audiogram are typically defined as falling within the range of 0 to 20 dB. This range indicates that an individual can hear sounds at very soft levels, which is essential for normal communication and interaction with their environment. A reading of 0 dB represents the threshold of hearing for a young, healthy individual with no hearing loss, while 20 dB is a level where quieter sounds are still audible. Therefore, anyone with hearing levels in this range would be deemed to have normal hearing. Levels above this threshold suggest varying degrees of hearing impairment, where sounds may not be detected as well, impacting overall auditory function.
