This paper presents a proposal of an efficient binaural room-acoustics auralization method, essential goal modeling. The method uses massively parallel wave-based solver based on dispersion-optimized explicit time-domain finite element (TD-FEM). hybrid technique first-order Ambisonics (FOA) and head-related transfer functions. encoding room impulse responses computed by that can model sound abs...

Hidden Markov models (HMMs) of speech acoustics are the current state-of-the-art in speech recognition, but these models bear little resemblance to the processes underlying speech production (Lee, 1989). In this respect, using an HMM to model speech acoustics is like using a Gaussian distribution to model data generated by a Poisson process – to the extent that the model is not an accurate repr...

Speech recognition should be as an eyes-free and handsfree interface. To realise this technology, we need to clarify acoustics in a helmet and determine how much highlevel riding noise affects captured speech data. This paper describes the acoustics in a helmet and transfer functions of the microphone position. We constructed a data collection system and collected the speech data of motorbike r...

Acoustic scientists and aural architects are fundamentally different. The former have the skill and experience to design a space that will have specific measurable acoustic properties (physical acoustics). The latter are able to discover what aural properties would be functional and desirable for the inhabitants (cultural acoustics). By focusing on aural architecture, we can design (real or vir...

Archeological acoustics is a part of acoustics that studies ancient environments which were dedicated (completely or partly) to sound performing. The combination of this acoustic area in conjunction with room acoustics enables the study of the acoustic evolution of existing buildings (in terms of the historical documentation) or even, make the acoustic reconstruction of rooms which were destroy...

Prediction models and computer simulations are indispensable tools for design and consulting in various fields of acoustics such as architectural acoustics and sound design for vehicles or household appliances. The reliability of results from such computer tools depends on the quality of the algorithm which provides a best estimate of the sound and vibration data of interest. Also relevant is t...

Viscothermal effects in air lead to a damping of high frequencies over time. Such effects cannot be neglected in large-scale room acoustics simulations for the full audible bandwidth. In this study, full-bandwidth room acoustics is modelled using a variant of the three-dimensional wave equation including viscothermal losses in air following from a simplification of the Navier-Stokes equations s...
