FOREWORD

Here to follow are the Proceedings of the 4th Course of the International School

of Physical Acoustics, which was held in Erice, Italy, from Oct 3 through Oct 10,

1991, at the International Center for Scientific Culture "Ettore Majorana". We are

proud to announce that the School is now well and lively active among all the other

Schools that for years have been holding courses at the E. Majorana Center. We began

some ten years ago, with a topic, "Fundamentals of ultrasonic wave propagation", that

was chosen on purpose to be as general as possible, in order to test the needs of the

acoustic community and possibility of continuing with topics of a more specific nature.

It appeared through the years that the seed was sown in a fertile field: participation

increased steadily, and the School kept on growing through the comments and works

of its participants.

Ultrasonics sensing and probing was the subject selected for the present course,

where the scholars were intended to be inticed into exchanging their ideas and

experiences with those involved in the many fields of applied science where sound

waves can contribute to give information about material and structure defects.

The interaction of sound waves with the medium of propagation results in effects

that can be used either to study the ultrasonic field itself, or to give information on the

medium. The sensing and/or probing of the ultrasound field is studied together with the

sensing and/or probing by the ultrasound field, unified by the effect of the interaction

of the field with the medium.

We called in papers from the two sides, and hoped to have cross fertilization of

interests. That really stands as one of the main scopes of the School: exchanging

experience and comparing results among people that have a common denominator in

their research work.

We do hope that the target has been partially fulfilled; at least, we presume we

did it in the past from the support the participants gave us to continue the School.

We also hope the Proceedings can enrich the readers and stimulate their interest

in ultrasonic sensing and probing.

Finally, we wish to express our gratitude to all those who contributed to the

success of the School: the sponsoring Institutions named on the front page; the people

at the E. Majorana Center in Erice for their warm support and hospitality; the staff at

the Corbino Institute of Acoustics in Rome for the organization, particularly Lucia

Covi, for her constant and intelligent catalizing action, and Gisella Menichelli for her

care in editing the manuscripts.
