Are the frist few reserved?

Ok, so I decided my TC was desperately in need of some sound, warp jump noises etc. What I would like to know is, are the first few sounds reserved for specific sounds such as with the desc and str/str# resources?

I presume:

"Presumptions" said:

128 must be warp up
129 must be warp up x2
130 must be warp out
150 - 154 (+?) are beeping noises
200 - 299 are weapon noises
300 - 369 are explosions
370 - Red Alert
371 Warning
372 Ejection

373-379 ??????

380-381 Cloaking On/Off

382-389 ??????

390- Airlock

391-599 ????

600-603 - Menu Buttons

600-999 ??????

1000-9999 Government Communications

10000+ Planet Noises

Has anyone got any ideas on the unknowns, or would be kind enough to correct me.

Thanks
