Nearfield Acoustic Holography (NAH) is an acoustic imaging technique used for the detection and estimation of fields of acoustic sources. Cylindrical NAH is especially used for localization of acoustic sources on a cylindrical surface. A known source (speaker) was reconstructed using two different approaches, namely direct NAH and Spatial Transformation of Sound Field (STSF). Acoustic pressures measured by the microphones were used to reconstruct pressure, velocity and intensity fields on the cylindrical surface at different radii. It was found that, both the approaches gave correct source localization, irrespective of the source frequency. The frequency response was also captutred by both these approaches.
