Multi-Source Low Frequency Room Simulation Using Finite Difference Time Domain Approximations

Document Thumbnail

Sound level distribution generated by loudspeakers placed in a room can be simulated using numerical methods. The purpose of this paper is to present an application based on. nite-difference time-domain approximations (FDTD) for the study of low frequencies in audio reproduction such as ordinary stereo to multi-channel surround setups. A rectangular room is simulated by using a discrete model in time and space. This technique has been used extensively and gives good performance at low frequencies. The impulse response can be obtained in addition to the sound level distribution. Simulation of multiple loudspeakers in a room can be achieved to evaluate and visualize their coupling with the room. A high frequency resolution can be obtained for auralization purpose.
