Abstract

Noise pollution has been shown to negatively affect human health and performance (Guidelines for Community Noise. World Health Organization., 1999). Instances in recovery or classrooms contexts exemplify this the best, where learning retention and overall attention spans are increased (Mealings, 2023). With many possible places to source inspiration from, one of nature’s greatest acousticians might help in mediating sounds. Bats, and their convex and uniquely shaped ears channel noises emitted from specific prey, allowing them to pinpoint the location of their food source (Muller et al., 2011). Specific and localized adaptations are species dependent, as their needs are different based upon natural factors. Thus, there are endless possibilities in exploring acoustic distribution, that can directly impact human interactions. Even though there are considerate benefits of improved noise quality, acoustics are often only considered as a second feature in the design process (Pallasmaa, 2024), leaving sounds and other consequential effects of usage to be mediated later. This oftentimes is done with panels that are attached to existing structures and fixtures in an already finished and built forms. Resulting compositions, therefore, take a “covering” function in environments, which understandably is the most accessible and immediate solution. Past designers have used similar approaches in the creation for flexible parametric acoustic panels that address acoustic problems (Peters et al., 2011). Comparison methodologies across species and families could yield many design opportunities to explore. Therefore, how might we extract and categorize formal features of bats’ ear canals to create parametric solutions that can be deployed in human contexts to enhance their acoustic needs?
