Abstract

The present invention discloses a device and method combining 3D sound effect processing and active noise control, which employs a digital signal processor to perform reverberation and sound positioning processing on audio signals and then play through a headset, and a sensor disposed in the front of a speaker to sense the surrounding interfering noise upon playing and feeding back to a noise controller; the noise controller generates an anti-noise signal to eliminate the surrounding interfering noise so as to achieve the object of increasing signal to noise ratio and enhancing the effect of 3D acoustic environment. Moreover, the present invention also focuses on the sound positioning processing of a head-related transfer function for carrying out the further improvement and replaces the head-related transfer function with a more efficient interaural transfer function to reduce overall operations.
