Description: This paper discusses research on acoustic cancellation in architecture. Abstract: Because of the propagation and interference of sound waves in a fluidic medium, acoustic cancellation due to architecture will often occur where it is least desired, such as in classrooms, churches, or presentation rooms. This dampening of sound may occur when evenly spaced structures are positioned at an interval roughly equivalent to half the wavelength of the sound being cancelled. Through the modeled and structural observance of this phenomenon, a theoretical model has been developed that can provide a means by which to determine the frequencies of sound that will be filtered out by a structure's inherent arrangement.
