The intensity of a sound describes
baherus [9]
The intensity of a sound describes <em>its loudness at a particular distance</em><em />

Sound intensity is factored by the ear's sensitivity to the particular frequencies contained in a sound

Sound loudness describes the strength of the ear's perception of a sound.

These two points being said, if the ear is more sensitive to a frequency, that sound will be louder to us than sounds at different frequencies that might not be as sensitive to our ears. <em>So, the more intense the sound, the louder it is ;)</em>

Thank you for your question! I hope this helped! Have an amazing day! :D
