**3. Methods**

In this work, we propose a model for the detection and recognition of the environment detection. This model is based on acoustic sensors and a model for the recognition of standing activities based on motion and magnetic sensors as an enhancement of a previous developed framework for the recognition of ADL and their environments [4–7,16]. The framework was designed to recognize the following ADL—running, walking, going upstairs, sleeping, going downstairs, sleeping, watching TV and standing. In addition, the following scenarios are also recognized by the framework—bar, classroom, gym, kitchen, library, street, hall, living room and bedroom.
