  The European programs for development of supersonic air-flights involve new
studies on the human perception of sonic boom. Because this noise includes
high-level components at very low-frequency, the usual psycho-acoustic tests
with headphones are not relevant; instead, the original sound-field can be
reproduced with many loudspeakers in a small room, but the loudspeakers must be
controlled for an accurate reproduction, both in time and space, in an area
large enough to enclose a listener's head. In this paper, Active Noise Control
is applied to sonic boom reproduction through Boundary Surface Control (as
named by S.Ise) of the acoustic pressure around a listener. A small room was
built at LMA with sixteen powerful low-frequency acoustic sources in the walls.
Frequency and time-domain numerical simulations of sonic boom reproduction in
this room are given, including a sensitivity study of the coupling between a
listener's head and the incident sonic boom wave which combine into the
effective sound-field to be reproduced.
