The world attached contains every trapdoor, with the exception of unwaxed copper trapdoors. They are also in the player inventory.
By interacting with the trapdoors in the world, you will notice a few things. Here are some that are consistent with what is expected:
The place and break noises are accurate to the material of the trapdoor.
The open and close noises are accurate to the material of the trapdoor
However, there are some noises that are inconsistent with what would be expected:
There is no walking noise for any trapdoor.
When walking on a bottom-half trapdoor, the walking noise will be taken from the block below the trapdoor, if it exists.
The jumping and landing noises for every trapdoor is the stone jump/land are the stone versions of the noise, despite no trapdoor being made out of stone.
I have noticed something new:
This may be caused by the walking sound check being placed further down than the player’s feet. I have come to this conclusion because an open trapdoor does seem to have walk, jump, and land sounds.
