We present a method for accurately synthesizing the acoustic response of a water bottle using modal signal processing. We start with extensive measurements of two water bottles with considerations for how the level of water inside the bottles, the area covered by stickers attached to the exterior of the bottles, and the method of striking the bottles affect their sound. We perform modal analysis of these measurements and implement a real-time modal water bottle synthesizer.
