Abstract
The one-dimensional, standing wave field was investigated by using the one-microphone, sequential sampling method. Various acoustical variables including complex sound pressure, complex particle velocity, active intensity, reactive intensity, kinetic energy, and potential energy were theoretically calculated and measured. The same investigations were performed in cases of both highly reactive and predominantly propagating waves. A detailed error analysis was carried out by comparing the experimental results and theoretical values. It was observed that phase and magnitude sampling mismatch was the primary contributing factor to the discrepancy. The effect of the sampling mismatch depended on the local field properties such as active intensity and potential energy density. In general, the phase sampling mismatch caused errors in velocity and active intensity, whereas the magnitude sampling mismatch caused errors in velocity and reactive intensity. Despite some errors occurring at a few field points, satisfactory agreement was achieved between the theoretical and experimental values for all acoustical variables of interest.
