متن کاملLecture Halls - Room Acoustics and Sound Reinforcement
This paper describes our experience with lecture halls with regard to the room acoustics, sound reinforcement and audio frequency induction loops for persons with hearing impairment. The optimum reverberation time and geometrical conditions for classrooms are well known. Recent research basically confirms this knowledge but indicates the need for shorter reverberation times. However, many exist...
متن کاملCavitation Scaling Experiments With Headforms: Bubble Acoustics
Recently Ceccio and Brennen [1][2][3] have examined the interaction between individual traveling cavitation bubbles and the structure of the boundary layer and flow field in which the bubble is growing and collapsing. They were able to show that individual bubbles are often fissioned by the fluid shear and that this process can significantly effect the acoustic signal produced by the collapse. ...
متن کاملExperiments on the loudness-transfer of headphone-based virtual acoustics
Binaural synthesis is a virtual-acoustics technology based on the convolution of sound signals with impulse responses modeling the propagation paths between sources and listener. The convolution products are typically presented by headphones. The frequency-dependent correction level necessary for a binauralsynthesis system to elicit the reference-scene loudness is referred to as loudnesstransfe...
متن کاملAcoustics of pianos: physical modeling, simulations and experiments
The outlines of a recently developed model of a grand piano are summarized. Using dedicated numerical methods, the main vibratory and acoustic variables of each constitutive part of the instrument (strings, bridge, soundboard, sound pressure) are simulated in the time-domain. The obtained waveforms are analyzed and compared with experimental data derived from measurements on a Steinway D grand ...
