The operations include acquiring, using a measurement microphone, reflected sound information regarding an effect of sounds that are played back by a plurality of speakers having predetermined directivity and that are reflected off an object, where the plurality of speakers are included in the speaker system. The operations also include calculating correction coefficients used to correct acoustic characteristics of the plurality of speakers on the basis of the acquired reflected sound information. The operations further include correcting the acoustic characteristics of the plurality of speakers using the calculated correction coefficients."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal processing method and speaker system","description":"A method is provided for causing a processor included in a speaker system to execute operations.
