On the Plausibility of a Personalized Acoustic in Automobiles

Inhalt:
With the emerging of algorithms able to automate or semiautomate the acoustical tuning process of sound systems m automobiles, it is nowadays possible to objectify the otherwise, almost exclusively, subjectively handled topic of acoustical sound tuning. Thus, by having a fully determined process, investigations, e.g. regarding plausibility of personalized acoustic in automotive environments, as proposed in this paper, became feasible. Thereby, by taking a certain demo car as test object, in which, for several single seat positions, as well as for different zones within its interior, special tuning sets have been generated, all based on the same RIR1 measurements, done once at the beginning, the question, whether it is plausible to personalize the acoustic in automobile environments, had been followed up. By utilizing two different kinds of measurements, one coping with the timbre and the other one covering the localization, an attempt was made to find an answer to this question, in an impartial manner.
