Generation device of simulated engine sound

摘要: PROBLEM TO BE SOLVED: To generate simulated engine sound similar to various actual sounds through a little memory information, by providing elemental sounds- synthetic means synthesizing plurality of processed transmission system simulation at an arbitrary volume ratio. SOLUTION: A driving signal-generation 12 generates signals corresponding the speed on basis accelation operation signal detected drive operation-detection 11. An output 13 outputs signals. fluctuation-treatment 14 processes with fluctuation treatment give time-variation against and frequency characteristic. In 15, transfer function according propagation passage way from source position ear operator is multiplied treated apply acoustic treatment. applied are synthesized ratio as (b), in 16 sounds.
