After lunch you put your head down on your desk to rest You hear very loud footsteps that you hadn't noticed before Why are the footsteps so loud now?

The loudness of the footsteps may be attributed to the change in acoustics when you put your head down on the desk. By altering the angle of your head and ears, you may have inadvertently amplified the sound of the footsteps. Additionally, the change in your position could have affected the way sound waves travel and reach your ears, making the footsteps seem louder than before.
