dc.description.abstract	Despite advances in audio technologies, people are highly concerned with an effect of audio sound disturbance and privacy issues related to an audio access. Coming up with a new technical direction to eliminate audio signal disturbance at local environment is very vital. Among the tasks to be done, controlling audio disturbance, providing unlimited access and preserving privacy of users are the most common. Many researchers of the field developed different frameworks (Bluetooth, wired audio divider, headphone) for the above-mentioned tasks on different infrastructure context. However, most recent frameworks are very limited to the number of user access they provide. This thesis follows DSRM to design a framework of versatile local audio signal distribution to control sound signal disturbance and to preserve privacy. To this end, the research conducts an assessment over existing system so as to define the exact problem and to identify user requirements. Based on the requirements, local audio signal distribution framework is designed. Design science research methodology is used to design and develop the prototype. An attempt is made to simulate and demonstrate the designed framework to evaluate the effectiveness, efficiency, portability and spectral efficiency against the objectives defined and the requirements specified. As a result, the designed framework of local audio signal distribution is effective for avoiding unwanted sound hearing loss. It is evaluated against defined requirements, research questions and objectives and defined solution objectives. The designed framework is 90% effective, 100% efficient, 95% easy to learn, 95% easy to use, 90% portable and 95% spectral efficiency. On average, the framework has 95% overall performance.	en_US
