dc.description.abstractAn acoustic camera records a sound field with a microphone array. Due to properties of the array, and by using beam forming algorithms, an acoustic camera can separate sound from different directions. The acoustic camera measures sound pressure from a sound source. By assuming directive properties, the sound power of a sound source can be derived from the sound pressure. In this project, an acoustic camera has been simulated using MATLAB in order to determine sound power estimation performance and sound source separation ability. The wave number-frequency response of an array describes the response to an arbitrary plane wave in both time and space. When the input consists of a single monochromatic plane wave, the response of the array is referred to as the array pattern or beam pattern. Through the design of the array, our goal is to have a directive of the array as high as possible in a given direction, while suppressing signals and noise from directions being different from our focused attention. The beam pattern of an array is a key element in determining array performance, and is largely determined by the array geometry. So, we have studied different shapes of array as square, triangle and circular array. Moreover, we changed the number of microphones or array size to have best directive. In addition, we have studied the effect of distance between array elements. Assuming there are two sound sources in different locations, we built a graphical user interface (GUI) by using MATLAB in order to change the position of each source and other properties of microphones array easily without going back to the original code.en_US
