Title:
VEHICLE-LIKE SOUND GENERATION DEVICE AND VEHICLE-LIKE SOUND GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2012/011163
Kind Code:
A1
Abstract:
Disclosed is a vehicle-like sound generation device, wherein: on the basis of sound pickup results obtained by a sound pickup section (150), a waveform extracting section (122) extracts a high-frequency component having a predetermined waveform included in the ambient sound of a vehicle (CR); on the basis of the extraction results and the sound pickup results obtained by the sound pickup section (150), a noise-level estimating section (126) estimates the noise level of the vehicle (CR) by calculating the level of sound found by removing a pseudo-engine sound component, which corresponds to the high-frequency component having the predetermined waveform, from the audible range component of the ambient sound; an output-level designating section (127) calculates a level designation value for outputting a pseudo-engine sound at a volume corresponding to the estimated noise level, and sends the calculated level designation value to an analog processing section (130); and the analog processing section (130) having received the level designation value adjusts the level of a pseudo-engine sound signal in accordance with the level designation value.
