Abstract
Provided is a method of correcting temperature characteristics of an audio device that includes a first microphone and a second microphone, including: measuring a temperature of the first microphone at a step (a-1); correcting an output signal of the first microphone at a step (b-1) using the measured temperature at the step (a-1); and calculating an output signal of the audio device at a step (c) using the corrected output signal of the first microphone at the step (b-1).
Claims12
A method of correcting temperature characteristics of an audio device that includes a first microphone and a second microphone, the method comprising:
- measuring a temperature of the first microphone at a step (a-1);
- correcting an output signal of the first microphone at a step (b-1) using the measured temperature at the step (a-1);
- and
- calculating an output signal of the audio device at a step (c) using the corrected output signal of the first microphone at the step (b-1).
An audio device comprising:
- a first microphone;
- a second microphone;
- a first correction unit correcting an output signal of the first microphone using a measured temperature of the first microphone;
- and
- an output unit calculating and outputting an output signal of the audio device using the corrected output signal of the first microphone by the first correction unit.
