Why do you think you can perceive some sounds as loud and others is very soft?

The perception of sound loudness is influenced by several factors, including the sound's amplitude, frequency, and duration. Higher amplitude sounds are perceived as louder because they create greater pressure variations in the air, while lower amplitude sounds produce less intense vibrations. Additionally, the human ear is more sensitive to certain frequencies, particularly in the mid-range, which can make some sounds seem louder than others even at similar amplitudes. Environmental factors and individual hearing sensitivity also play a role in how we perceive sound loudness.
