Abstract
A new method for the combined simulation of the audio and haptic response of an acoustic environment for arbitrary musical source material based on physical measurements is presented. Tactile signals are reproduced by the convolution of "decoupled" vibration with impulse responses derived from mechanical impedance measurements. Audio signals are reproduced by the convolution of anechoic sound with binaural room impulse responses. Playback is accomplished through headphones and a calibrated motion platform. Benefits of combining the new method of tactile signal reproduction with known audio auralization techniques include the ability to perform side-by-side listening tests for audio-tactile stimuli perceived in real music performance situations. Details of the method are discussed along with obstacles and applications. Structural response measurements indicate that propagation time and magnitude attenuation with distance vary perceptibly depending on both floor construction and direction of travel. One method of analysis shows that tactile and acoustical impulse responses vary independently across environments, supporting the need for measured vibration signals in audio-tactile displays. The results of the study can be used to calibrate haptic displays for music reproduction, but also to build test environments for perceptual studies aiming to improve stage construction with regard to vibration characteristics.
