Abstract This article reflects on an ongoing artistic research practice that deals with sound, gender, power, spatiality, and human–nonhuman entanglement. Sparked by a sound design for a less crunchy “lady-friendly” crisp, the research inquires the relationship between gender and sound at human–nonhuman encounter through making and thinking. Drawing on queer theory, sound studies, and posthumanism, it aims to transcend essentialist, vision-focused, and anthropocentric conceptualisations of gender and, as an insight gained from working with low-frequency sound waves, it reflects on sound as material-philosophically demonstrating human–nonhuman interconnectedness. The latter, as this article proposes, may encourage us to horizontalise hierarchies between the human and nonhuman. Finally, this text situates sonic thinking as a mode of trans*formative thinking: a process-oriented philosophy that aims to embrace the messy, queer ways of human–nonhuman relationality, which characterises a vibrant space from which this artistic research will further develop.

Underwater acoustic wave absorption and control play an important role in underwater applications. Various types of underwater acoustic metamaterials have been proposed in recent years with the vigorous development of acoustic metamaterials. Compared with airborne sound, underwater sound waves have a longer wavelength and much smaller propagation loss, making them more difficult to control. In addition, given that the acoustic impedance of water is much greater than that of air, numerous conventional materials and structures are not suited to underwater use. In this paper, we propose a composite structure based on an excellent broadband low-frequency sound absorber of air using aluminum mixed with rubber. Our composite structure possesses broadband low-frequency (<1,000 Hz) sound absorption underwater, omnidirectional high sound absorption coefficient under the oblique incidence (0–75°), and pressure resistance. It has promising applications for underwater acoustic wave control and contributes to the design of underwater acoustic metamaterials.
