The database used in the experiments reported in this
paper contains 822 sounds of 6 different classes
associated to intrusion or aggression situations : 314 door
slams, 88 glass breaks, 73 human screams, 62 explosions,
225 gun shots and 60 other stationary noises. The sounds
were taken from different sound libraries (BBC, Warner,
Noisex-92 [2]) and there is a lot of variability within a
same class (differences of quality, differences in signal
length, different signal energy levels, etc)
