Resumo: <\/strong>No estudo da queda livre costuma-se desprezar as energias dissipativas decorrentes do atrito, energia t\u00e9rmica e sonora durante a colis\u00e3o quando a part\u00edcula atinge o solo. Apresentamos um m\u00e9todo para efetuar medidas experimentais da contribui\u00e7\u00e3o da dissipa\u00e7\u00e3o devida ao som em uma colis\u00e3o el\u00e1stica. Utiliza-se a t\u00e9cnica de videoan\u00e1lise para obter a posi\u00e7\u00e3o da part\u00edcula com o uso do software Tracker e, para a capta\u00e7\u00e3o e an\u00e1lise do som produzido durante as colis\u00f5es, usa-se o software Audacity, sendo ambos softwares livres. Os c\u00e1lculos efetuados a partir das medi\u00e7\u00f5es apresentam resultados convincentes em termos proporcionais quando comparados com outros observ\u00e1veis no experimento. O m\u00e9todo aplicado mostrou-se adequado quanto a precis\u00e3o exigida, por\u00e9m a execu\u00e7\u00e3o do experimento evidenciou possibilidades de aperfei\u00e7oamento na etapa das medi\u00e7\u00f5es.

Abstract: <\/strong>In the study of free fall, it is usual to neglect dissipative energies resulting from friction, thermal and sound energy during the collision when the particle hits the ground. We present a method for making experimental measurements of the contribution of sound in an elastic collision. The videoanalysis technique is used to obtain the position of the particle, by the using Tracker software, and for the capture and sound analysis, by the Audacity software. Both of then are free software. The calculations performed from the measurements present convincing results in proportional comparative terms when confronted with other experimental observables. The applied method demonstrated to be adequate in terms of the required precision, even though the execution of the experiment has shown possibilities for improvement in the measurement step.<\/em>
