“…The body of contemporary steelpan research can be broadly grouped onto three categories covering: (1) The material of the steelpan; (2) The vibration of the steelpan and notes; and (3) the acoustics of the steelpan. Of these research areas, perhaps the least studied has been the acoustics of the steelpan.…”

The sound-field of a Caribbean low tenor steelpan is examined using nearfield acoustical holography (NAH). The particular instrument, a Bertrand Kelman low tenor, has been previously examined in a single plane using a four microphone sound intensity technique. This paper will examine the sound radiation in a cuboid space enclosing the instrument at three frequencies. Presented will be the results of sound pressure level (SPL), active acoustic intensity (AI), and reactive acoustic intensity (RI) obtained through application of the NAH technique. The limitations of NAH when applied to an irregularly shaped object such as a tenor steelpan will also be presented.
