Children shouting, crying.
Karang guni man calling out.
Small dog yapping.
Bird chirping.
Drilling, knocking on walls.
Water rushing down pipes in toilet.
Sound of strong wind, whoo whooing.
Lift bell ringing.
Vehicles honking, or alarm going off.
Karaoke, bad voice only, no music.
Next door neighbours, comming and going
HDB blocks are never silent.
