Using autonomous drones for positioning and tuning speakers in a room, could give the owners of the speakers a better and more personalized sound experience, if the speakers are tuned for the environment. As a first step towards that goal this project investigated methods that could use data gathered from a Crazyflie drone to identify interesting acoustic properties of a room. The problem was divided in to two sub problems, 3D reconstruction and acoustic modeling. 3D reconstruction of rooms and acoustic modeling are both popular areas of research and many kinds of methods and techniques exist in both fields. While 3D reconstruction is a recent area of research that has gained popularity in the last two decades, mainly as a way to update architectural models, acousticmodeling is a more established area of research that started in the early 1960 and is manly used to improve the immersion in games by making sounds more realistic. In this project the engineering design process was implemented in both parts of the project. This process lead to the conclusion that the Time of Flight (ToF) distance sensors of the Crazyfliecould be used to create 3D models and that Elmer and Pyroomacoustics where good tools to performacoustic modeling. The results show that the data from the Crazyflie could potentially be used to determine acoustic properties of a room using the techniques and methods of this project.
