Abstract: Provided are a forming method for a personalized sound zone and a forming system thereof. Using The forming method for a personalized sound zone, by calculating a control filter reflecting the characteristics of individual speakers, a numerical error and resultant occurrence of noise may be reduced when the filter is calculated, and an effective personalized sound zone may be formed only with directivity without a control filter at a frequency band in which sound between seats are separable according to distances.

Abstract: An acoustic spatial adjustment system may be provided that includes: a wireless communication module which receives a voice signal from a mobile terminal connected thereto by wireless communication; an adjustment controller which filters the voice signal in order to generate a sound source signal for focusing an output of the voice signal transmitted from the wireless communication module on a bright zone (BZ); an amplifier which divides the sound source signal transmitted from the adjustment controller into multi-channels and amplifies; and a plurality of speakers which output the sound source signal transmitted from the amplifier. As a result, the sound can be focused on a specific zone in the vehicle by using existing mounted speakers in the vehicle or by installing only additional speakers for performance improvement. Also, the individually distinguished sound (audio signal of a stereo system, CD, DVD, etc., a telephone voice signal connected by Bluetooth, etc.
