An application of block-based physical modeling for digital sound synthesis is presented in this paper. A membrane model in terms of a fourth order, two-dimensional partial differential equation is solved and discretized with the functional transformation method. The resulting algorithm constitutes an input-output description with input force and output velocity of the membrane. This input-outp...

Engraving–Hammering–Casting is a live music composition written for two performers, who interact with forcefeedback haptic interfaces. This paper describes the philosophy and development of the composition. A virtual physical model of vibrating resonators is designed and employed to generate both the sound and the haptic force feedback. Because the overall system, which includes the physical mo...

This paper presents a new interface for controlling sonification models. A haptic controller interface is developed which allows both to manipulate a sonification model, e.g. by interacting with it and to provide a haptic data representation. A variety of input types are supported with a hand-sized interface, including shaking, squeezing, hammering, moving, rotating and accelerating. The paper ...

Cumulative tool-based culture underwrote our species' evolutionary success, and tool-based nut-cracking is one of the strongest candidates for cultural transmission in our closest relatives, chimpanzees. However the social learning processes that may explain both the similarities and differences between the species remain unclear. A previous study of nut-cracking by initially naïve chimpanzees ...

Rock and soil penetration by coring, drilling or abrading is of great importance for a large number of space and earth applications. An Ultrasonic/Sonic Drill/Corer (USDC) has been developed as an adaptable tool for many of these applications [Bar-Cohen et al, 2001]. The USDC uses a novel drive mechanism to transform the ultrasonic or vibrations of the tip of a horn into a sonic hammering of a ...

Musculoskeletal disorders (MSDs) are common health problem throughout the world and a major cause of disability in the workplace. This study was conducted among workers of a small scale forging Industries. The small scale forging units involve various kinds of high repetitive processes like Blanking, cutting, shearing, furnace loading, hammering, punching and trimming etc. the workers performin...

Across spoken languages, properties of wordforms (e.g. the sounds in the word hammer) do not generally evoke mental images associated to meanings. However, across signed languages, many signforms readily evoke mental images (e.g. the sign HAMMER resembles the motion involved in hammering). Here we assess the relationship between language and imagery, comparing the performance of English speaker...
