Patent ID: 7530424

Claim:
An acoustic event simulator, comprising: an acoustic waveguide having first and second ends and exhibiting a substantially constant cross-sectional profile along its length; an infra to low frequency sound source; a horn for coupling sound emitted from the infra to low frequency sound source into one end of the acoustic waveguide, the horn having a mouth substantially corresponding to the cross sectional profile of the waveguide; a low to high frequency coherent sound source located in the mouth of the horn; a bass trap terminating the acoustic waveguide at an end of the acoustic waveguide opposite the mouth for dampening low frequency sound in the acoustic waveguide while allowing reverberation of higher frequency sound produced by the sound sources to emulate a free field environment; and the dimensions of the acoustic waveguide admitting a test subject at a location in front of the mouth where sound fronts propagating across the test subject from the infra to low and low to high frequency sound sources are substantially coherent.
