When you see a CA object, do you ever wonder what sound it would make?
Here’s my thoughts for sounds:
Blocks are silent when created and remain untouched, but make a wooden sound when they interact.
Go ahead and put your objects and associated sounds.

I think a snake would hiss when touched (e.g. used as a rock catalyst) but otherwise remain silent. A glider would make a very quiet, rhythmic tick-tock sound as it traveled (making one tick every generation), would let out a quiet breath if it were eaten, and would make a bonking sound when reflected.

xwss makes swooshy sounds! :3
beehive would make a subtle humming, and when touched, the humming gets louder, and when destroyed, it get super louder
loaf would make bread noises in appropriate places
loafer would make constant bread noises
ponds would have a water sound but when touches it sounds like a ripple :D
mangoes are like loafs but with moving fruit sounds
tlife's ant would periodically make a climbing sound everytime it reached a specific state
explosive rules that are filled with content like seeds make a random sound like jdrnhfjdgsxnk

A blinker would click every generation, because...well...car blinkers.
A boat would probably slosh the water around, but that's about it.
A ship would be louder than a boat.

both clocks would, well, work as clocks

beacons high five
pulsars make a cooking sound

The switch engine makes a semi-high pitch trilling/chirping sound when it moves vertically, in time to when it moves, and same for horizontal movement, but the pitch would be lower.

It'd be like TRR TRR TRRRRRRR trr trr trrrrrrr TRR TRR TRRRRRRR trr trr trrrrrrr TRR TRR TRRRRRRR trr trr trrrrrrr

the space rake says "skibidi bop bop bop skibidi yes yes yes" over and over again every time it releases a glider. it can stack too

The BLSE and GLSE are very noisy: BLSE has trilling sounds and constant wood-on-wood sound. GLSE's ticking sound grows louder every minute, overwhelming the trilling sound eventually.

Knightships like Sir Robin would make a galloping sound.
But the sprayer would make make a spraying sound.

blinkers are like DINGDINGDINGDING
also pinwheels sound like someone skating and an xwss sounds like the enterprise from star trek
and ponds sound like ducks
and 22P36 sounds like an old hard drive starting up for some reason (80s kids will know what i mean)
EDIT:
pi heptonimo sounds suspiciousy similar to my math teacher explaining how important pi is in geometry
