Stuck on Geo puzzle at kingdom's bridge

[Triton]

As title says, the first two rooms are trivially easy and for some reason I'm just stumped on the third. I have no clue what to do and help would be greatly appreciated.

You need to listen for when the switch is pressed. Try turning up the volume.

Ah well, that sucks. I suffer from tinnitus so I struggle picking up subtle audio queues like that. I eventually managed to brute force the solution by chance luckily.
