Abstract

L'invention concerne un système d'audiométrie tonale et un procédé permettant de tester simultanément plusieurs patients. Le système comprend: une pluralité de terminaux utilisables par les patients pour effectuer eux-mêmes au moins un test d'audiométrie tonale comprenant un test en conduction aérienne, un test en conduction osseuse et un test de masquage; et un serveur d'examinateur connecté à chaque terminal de patient pour contrôler des informations sur l'état de l'examen pour chaque patient et les résultats de l'examen, sur la base des données de test d'audiométrie tonale obtenues de chaque terminal de patient. En conséquence, un seul et unique examinateur peut conduire et gérer le test auditif sur plusieurs patients en même temps, ce qui est avantageux pour ces derniers qui peuvent ainsi bénéficier de frais d'examen réduits et de délais d'attente plus courts.
