The Sonel Mapping Acoustical Modeling Method
نویسندگان
چکیده
This work investigates the application of photon mapping to model environmental acoustics. The resulting acoustic sonel mapping technique is a MonteCarlo based approach that can be used to model acoustic environments while accounting for diffuse and specular acoustic reflections as well as diffraction effects. This modeling is performed in an efficient manner in contrast to available deterministic techniques. The sonel mapping approach models many of the subtle interaction effects required for realistic acoustical modeling.

Sonel Mapping: A Probabilistic Acoustical Modeling Method
Sonel mapping is a Monte-Carlo-based acoustical modeling technique that approximates the acoustics of an environment while accounting for diffuse and specular reflections as well as diffraction effects. Through the use of a probabilistic Russian roulette strategy to determine the type of interaction between a sound and any objects/surfaces it may encounter, sonel mapping avoids excessively larg...

متن کاملInvestigation of the effect of electrolyte on acoustical behaviour of ceramic coatings produced by method Plasma Electrolytic Oxidation (PEO) on titanium
In this paper, titanium oxide coating (TiO2) was produced on titanium alloy Ti6Al4V by Plasma Electrolytic Oxidation (PEO) Method. Sodium Silicate (Na2SiO3) and Sodium Aluminate (NaAlO2) based electrolytes were selected in PEO process. The effects of concentration of Sodium Aluminate (0, 2.5, 5, 7.5, and 10 g/L) on the microstructure and acoustical behaviour of the formed coatings were studied....
