Far away: People talking in a classroom, a small beep, the sound of an air conditioner
Medium: Footsteps (some going further and some coming closer), the entrance door slamming, a classroom door being shut
Closest: The sound of me breathing due to congestion, someone taking a sip of their drink, typing, someone chewing
The sound level started out quite loud, but it has now gone down to barely any sounds that aren’t the ones mentioned in #4. This is the same regarding the sound activity. Originally, it began with hearing #2 and #3 together, and those sounds faded away, which led me to hear #4. Therefore, the sound activity went from high to low.
Descriptor: Bustling
The essential sounds are: the faraway sound of people talking in a classroom, the sound of footsteps, and the sound of the entry door slamming.
