Abstract:

What can possibly be scientifically interesting about such a mundane chore as pouring a liquid into a glass? We perform this action all the time but barely realise that we effortlessly learn to infer several useful physical properties in the process. For example, evidence in psychoacoustics suggests that humans can accurately infer the level of the liquid, the time to fill, the size of the container, and even the temperature of the liquid merely from the sound of liquid. How do we do it? What is the physics behind pouring? How can we use it to train an audio model to predict some of these physical properties solely from the sound of pouring? I will answer these questions in the talk.
