The BBC has released 16000 sound files see http://bbcsfx.acropolis.org.uk/
I couldn't find the conditions under what kind of licence a file could be added to noice. So maybe the licence of the files does not fit to noice.

These 16,000 BBC Sound Effects are made available by the BBC in WAV format to download for use under the terms of the RemArc Licence. The Sound Effects are BBC copyright, but they may be used for personal, educational or research purposes, as detailed in the license.
