Development of Interior Sound for a Medium Coupe with Sportiness as an Objective Evaluation Index

Article of Honda R&D Technical Review Vol.14 No.2

Summary

A new model medium size coupe was developed with consideration of a sporty interior sound. Subjective evaluation of competitor vehicles was correlated with measured objective results to establish a target interior sound index. The target values on this index were determined at the concept stage of development with respect to relative position of competing cars. As a result of subjective evaluation of artificial interior sounds that represented candidate target values, a target sound was established. The air intake system from the base sedan was modified exclusively for the coupe. Adjustments to intake tube diameter, length, and intake inlet position resulted in an exclusive coupe intake sound. This yielded an interior sound with the sportiness and linear feeling that was desired under acceleration.
