Method for calculating digital sound source filters to generate differentiated listening areas in a confined space such as a vehicle interior

摘要

The invention relates to a method for calculating digital filters to be applied to sound sources (L1-L8) of a sound system with differentiated listening zones (Z1, Z2), the system comprising an equal total number of sound sources. to L, the method comprising the steps of: - setting the digital filter (F2 ', F3') to be applied to at least one sound source (L2, L3); - determine the digital filters (F1 ', F4'-F8') to be applied to the other sound sources (L1, L4-L8), or non-imposed filters, the non-imposed filters (F1 ', F4'-F8') being calculated taking into account the contribution of the sound source (s) (L2, L3) whose filters are imposed.
