Background noise for an old radio broadcast speech
sound of a kitchen microwave timer beeping
Static and pops with one "plink" sound where needle hits surface scratch.
Thunder in the distance recorded with Blue Yeti
cracking a soda can recorded on my iPhone in FingerBeat
A man sighing and moving slightly.
An egg timer with a bell ding at the end.
a passing by car from left to right
A smack or high five sound.
