SOUND OUTPUTTING APPARATUS, SOUND OUTPUTTING METHOD, SOUND OUTPUTTING SYSTEM AND SOUND OUTPUT PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To reduce a sound leak by evaluating and deciding whether sound leak suppression is necessary while taking a noise in a listening environment into consideration.;SOLUTION: The sound outputting apparatus includes an electro-acoustic conversion section 11 disposed in a housing 2 to cover an ear of a listener, a first sound signal being supplied to the electro-acoustic conversion means to reproduce sound. The sound outputting apparatus is provided with a surrounding noise evaluation section 223 configured to evaluate surrounding noise outside the housing based on a second electric signal obtained through sound collection by a sound collection section 12 configured to collect surrounding sound outside the housing 2. The sound outputting apparatus is further provided with a control section 222 configured to control the volume of the sound acoustically reproduced and output by the electro-acoustic conversion means for the first sound signal based upon a result of the evaluation of the surrounding noise evaluation section about the surrounding noise outside the housing.;COPYRIGHT: (C)2008,JPO&INPIT
