The normal ear is the most sensitive in the frequency range___________________?
Correct answer: C. 2000 to 4000 hertz
- A. 20000 to 30000 hertz
- B. 10 to 20 hertz
- C. 2000 to 4000 hertz
- D. 6000 to 8000 hertz
Explanation
The human ear is most sensitive to frequencies around 2000 to 4000 Hz, where the threshold of hearing is lowest. Sensitivity is not greatest at the upper hearing limit of 20000 Hz. Students may choose 6000 to 8000 Hz because it is still within the audible range, but audible range and maximum sensitivity are different ideas.

About Speed of Sound
The speed of sound depends on the properties of the medium, including its elasticity and density, and in gases it varies mainly with temperature. Questions connect speed with frequency and wavelength, compare sound in solids, liquids and gases, and distinguish the speed of propagation from the oscillating particles' motion.
