What is it that makes certain sounds scary? Why are screams particularly evocative? To explore this, I will discuss insights almost three decades of studying marmots - large, mostly-alpine, ground squirrels – that live throughout the northern hemisphere. I will talk both about the evolution and function of alarm calls, and end with a discussion of similarities among species, including humans, in the structure of fear screams and other scary and arousing sounds. I will discuss correlative and experimental studies on humans to evaluate the hypothesis that fearful and arousing sounds contain specific types of nonlinear acoustic phenomena, including noise. Finally, I review recent experimental work where by composing ‘marmot-inspired music’ we have determined that noise and other non-linear phenomena may be generally arousing and fear inducing. The sound of fear may indeed be noisy.
