SYSTEM DESCRIPTION

ACTIVE NOISE CONTROL SYSTEM

(a) The active noise control system is a system that detects muffled engine sounds produced in sync that fluctuates according to the engine speed, by using the active noise control microphone and outputs anti-phase control sound through the audio speakers to reduce muffled engine sounds.

The active noise control system includes the following functions.

Function Name	Function Description	Operation Conditions
ANC (Active Noise Control) Function	Function that reduces noise by using anti-phase and vibration control sound to interfere with muffled sounds	Engine running, engine speed 700 rpm or higher
ESE (Engine Sound Enhancement) Function	Function that produces realistic engine sounds by adding frequency component sound according to driving conditions such as vehicle speed and accelerator pedal depression	Engine running, engine speed 2000 rpm or higher
