A acoustic equalization method, and a robot and an AI server implementing the same are disclosed. The robot inputs space information with respect to a certain space and location information of a user to an artificial neutral network-based algorithm model to calculate an equalization value with respect to the certain space. Here, the space information is calculated based on at least one of a first acoustic signal output and received at a first point in the space, an image acquired through a camera, and distance information related to a space sensed through a sensing unit.
