This thesis evaluated and defined audio ergonomic resources through the analysis of corporative sites from Internet, verifying the acceptance of these resources with the user. Initially, related concepts to audio application in sites of the Internet were presented to better understanding envolved processes. Later, procedures had been carried through to establish scopes and audio ergonomic resourses effects in the user experience were evaluated. It was noted that the adequacy of audio ergonomic resources is a primordial factor in sites that use audio in the Internet and the lack of tests with the user in the process of development of sites compromises the audio applications. Without knowing the mental-model of the user, it is impossible to define the most important itens related to audio. The importance of organizing research data results to assist in the development of projects that involve ergonomic or usability aspects was also noted. Thus, conclusions on the main audio ergonomic resources had been presented in distinct sections to facilitate its applications.
