Final answer:
The human range of audible frequencies is 20 Hz to 20,000 Hz, with sounds outside this range being called infrasound or ultrasound and are typically not audible to humans. The answer is option B.
Step-by-step explanation:
The range of frequencies that humans are capable of hearing is 20 Hz to 20,000 Hz. This means that any sound with a frequency lower than 20 Hz is known as infrasound and is typically not audible to humans, although it can sometimes be felt as vibrations.
Similarly, sounds with a frequency higher than 20,000 Hz fall into the category of ultrasound and are not perceived by the human ear. It is interesting to note that animals have different hearing ranges. For instance, dogs can hear up to 45,000 Hz and bats can hear frequencies as high as 110,000 Hz. Humans, however, will commonly use the auditory range of 20 to 20,000 Hz for day-to-day hearing and communication.
