Document Type and Number:
Japanese Patent JP2016015585
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a signal processor capable of absorbing individual differences and allowing users to listen sounds assumed by a designer.SOLUTION: A signal processor 100 collects sounds which are output from a driver 11 which is provided to a headphone housing 10 via a microphone 12, and compares the characteristics of the sounds collected by the microphone 12 to the characteristics of an audio signal 2 supplied to a headphone. An airtightness estimation section 106 compares the characteristics of the audio signal 2 which is supplied to the headphone to the characteristics of an audio reproduction signal which is output from a microphone amplifier 104. An adder 114 adds a noise reduction signal which is output from a DNC individual adjustment filter 112 to the audio signal 2 which is output from a sound quality adjustment filter 102 to output the added signal to a power amplifier 116.
