The beginning ofthe overseas Acoustical Imaging Symposium sequence might be traced to 1967, while a gathering on acoustical holography used to be held in C alifornia. In these days, acoustical holography used to be on the cutting edge of study yet, because the significance of this topic waned, so the identify of the sequence used to be replaced from Acoustical Holography to Acoustical Imaging in 1978. The early Symposia have been held at a variety of venues within the usa. In 1980. the sequence turned foreign, with the Symposium that yr happening in Cannes in France. The development now could be to aim to met alternately within the united states and in one other a part of the area in order that energetic researchers in every single place can very easily attend at a pretty excessive frequency. It was once a very good privilege for us in Bristol within the uk to be selected to host the twenty fifth Symposium, which convened on 19 March 2000 and unfold over 4 days. We have been blessed not just via solid climate, but additionally by way of the attendance ofnearly a hundred pa rticipants who got here from 17 c ountries. a great number of papers have been permitted for presentation, both orally or as posters. even if an oral presentation or a poster, all have been thought of to have equivalent advantage, and no contrast is made among them within the released lawsuits. there have been no parallel periods, so each player may perhaps attend each presentation. The re sultant disciplinary go fertilisation maintained the t radition of earlier Symposia.

The directivity spectrum for a focused bowl shows, remarkably, discrete zeros, or ‘nulls’, at certain locations. Frequency nulls are not seen for planar transducers, and their location, in the focused case, depends only on the curvature of the bowl. Their presence is thus not related to the physics of the problem, but is dictated by geometrical considerations. Frequency nulls will influence the directivity function at certain frequencies only. Under such circumstances, the directivity function will not be peaked along the beam axis, but will be double humped - a feature which has been ascribed to faulty transducer manufacture.
