Abstract: An impact detection device includes: a body configured to be struck; a vibration sensor that detects vibration of the body; a support base that supports the vibration sensor; a first elastic body sandwiched between the vibration sensor and the body; and a second elastic body sandwiched between the vibration sensor and the support base. A dimension of each of the first elastic body and the second elastic body is smaller than a dimension of the vibration sensor when viewed from an arrangement direction in which the first elastic body, the vibration sensor, and the second elastic body are arranged.

Abstract: A signal processor includes an image obtainer, an estimator, and an outputter. The image obtainer obtains a performance image including playing of a drum. The estimator estimates a degree of attention attracted by the playing of the drum included in the performance image by inputting the performance image into a learning model. The learning model has been subjected to machine learning to estimate the degree of attention based on a feature quantity related to the playing of the drum. The outputter outputs the degree of attention estimated by the estimator.
