Abstract
A refrigerator includes a microphone and at least one processor configured to identify a first driving noise level corresponding to first driving state information of the refrigerator, based on receiving an ambient noise through the microphone while operating according to the first driving state information, identify a reception noise level based on the received ambient noise, identify an external noise level based on the reception noise level and the first driving noise level, and based on a ratio of the external noise level to the first driving noise level being smaller than a threshold ratio, drive the refrigerator based on second driving state information corresponding to a lower noise level than the first driving state information.
Claims20
A refrigerator comprising:
- a microphone;
- and
- at least one processor configured to:
- identify a first driving noise level corresponding to first driving state information of the refrigerator,
- based on receiving an ambient noise through the microphone while operating according to the first driving state information, identify a reception noise level based on the ambient noise,
- identify an external noise level based on the reception noise level and the first driving noise level, and
- based on a ratio of the external noise level to the first driving noise level being smaller than a threshold ratio, drive the refrigerator based on second driving state information corresponding to a lower noise level than the first driving state information.
A control method of a refrigerator, the control method comprising:
- identifying a first driving noise level corresponding to first driving state information of the refrigerator;
- based on receiving an ambient noise through a microphone of the refrigerator while operating according to the first driving state information, identifying a reception noise level based on the ambient noise;
- identifying an external noise level based on the reception noise level and the first driving noise level;
- and
- based on a ratio of the external noise level to the first driving noise level as being smaller than a threshold ratio, driving the refrigerator based on second driving state information corresponding to a lower noise level than the first driving state information.
A non-transitory computer-readable recording medium including a program executing a control method of a refrigerator, the control method comprising:
- identifying a first driving noise level corresponding to first driving state information of the refrigerator;
- based on receiving an ambient noise through a microphone of the refrigerator while operating according to the first driving state information, identifying a reception noise level based on the ambient noise;
- identifying an external noise level based on the reception noise level and the first driving noise level;
- and
- based on a ratio of the external noise level to the first driving noise level as being smaller than a threshold ratio, driving the refrigerator based on second driving state information corresponding to a lower noise level than the first driving state information.
