Focus on Black Hole Horizon and analyze the Construction.
Each of the horn objects is constructed like a wind instrument. A membrane chamber is excited through compressed air, which generates the sound. The resulting airflow hits a soap bubble membrane, forms the soap bubble and eventually extrudes it. A liquid circuit supplies the digitally controlled mechanics with the required amount of soap bubble solution. The three horn objects are tuned differently, each holding a static frequency that is defined by the length of the sound-amplifying tubing. The shape of the horn objects was developed using a series of digital simulations.
