Electronic apparatus and control method thereof

An electronic apparatus comprising:

• a communication interface;
• a microphone;
• and
• a processor configured to be connected to the communication interface and the microphone to control the electronic apparatus,
• wherein the processor is configured to:
• obtain a first expectation value which is a predicted measurement value for a first sound to be output by a first external electronic apparatus based on first location information of the first external electronic apparatus and a second expectation value which is a predicted measurement value for a second sound to be output by a second external electronic apparatus based on second location information of the second external electronic apparatus;
• control the communication interface to transmit a first sound output request signal to the first external electronic apparatus to request the first sound to be output by the first external electronic apparatus, and based on the first sound being output from the first external electronic apparatus in response to the transmitted first sound output request signal, obtain a first measurement value for the first sound received through the microphone;
• control the communication interface to transmit a second sound output request signal to the second external electronic apparatus to request the second sound to be output by the second external electronic apparatus, and based on the second sound being output from the second external electronic apparatus in response to the transmitted second sound output request signal, obtain a second measurement value for the second sound received through the microphone;
• obtain a correction value for one or more of the obtained first measurement value of the received first sound and the obtained second measurement value of the received second sound obtained through the microphone based on the obtained first measurement value, the obtained second measurement value, the obtained first expectation value, and the obtained second expectation value;
• and
• based on the obtained first measurement value being not within a first threshold range based on the obtained first expectation value and the obtained second measurement value being within a second threshold range based on the obtained second expectation value, obtain a correction value for a measurement value of a sound output at a location within a threshold range based on a location corresponding to the first location information.
