    Abstract : 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. READ MORE

  3. 3. Empirical Verification of an Acoustic Estimation of a Rocket Engine : A Comparison Between Estimated and Measured Noise of a Rocket Engine

    University essay from KTH/Skolan för industriell teknik och management (ITM)
