The term is commonly used to describe surfaces that exhibit a coarse or gritty feel, as well as sounds that are harsh, grating, or abrasive. Raspiness can be a natural property of certain materials or an engineered feature used to achieve specific sensory effects.
In materials science, raspiness is observed in surfaces with high roughness or micro-structured textures, such as
Raspiness can serve functional roles in nature and design. For example, some plants and animals possess rough
Overall, raspiness is characterized by a sensory impression of roughness and abrasiveness, whether in tactile textures
