The main aim of the study was to compare the features of acoustic maps created on the basis of measurements of sound pressure and intensity in a near acoustic field. Data for comparisons were obtained within the framework of acoustic tests of electric cookers. The results of these studies may help in the selection of acoustic mapping and optimization methods according to individual needs and/or requirements concerning selectivity, measurement bandwidth, dynamics and the ability to locate sound-emitting areas. The paper also presents the results of the spectral analysis of the dominant sources of noise in the cooker, which was helpful in identifying and locating paths of noise propagation from the inside of the cooker.
