The detection and identification of impulsive sounds applied in a specific context, particularly in sports events, enables the analysis and synthesis of various metrics and statistics associated with the game or even the player's performance. In this context, the automatic identification of an impulsive sound, such as a ball being hit by a player, is a major contribution to the construction of a data source on which game-specific analysis can be performed. Considering all the characteristics (features) of a particular type of impulsive sound in various conditions/environments involves dealing with numerous variables, making it equally challenging to efficiently find the values of the hyperparameters that allow obtaining the best configuration for a given algorithm to be executed in a machine learning process. The contribution of this work is to explore the hyperparameter space in search of values that optimize the performance of the entire process of automatic impulsive sound classification. This process begins with the generation of the dataset to be processed, continues with the training of classification models, and ends with the evaluation of the learned models. The experiments consider a binary classification problem, where a distinction must be made between the intended event and noise. The validation of the process resorts to an audio extracted from videos of sports event competitions, specifically in tennis and padel, where the goal is to identify the sounds of racket hits on the ball. This work is currently in progress, but the preliminary results already enable to evidence the impact of hyperparameter optimization on the accuracy of the overall learning process.
