2^nd International Conference on Acoustics and Vibration

I strongly thank God Almighty for granting us the opportunity of congregation one more time with the researchers, engineers and experts of acoustics and vibration through The Second International Acoustics and Vibration Conference, ISAV2012, in order to share our finding and mutual concerns in this field.
The growing significance of this field in all branches of engineering is fully clear which undoubtedly lead to new grounds for improving and serving the society. Vibration, more precisely, mechanical vibration as the main field, along with acoustics, as complement one another, express their vitality in all parts of the engineering aspects.
In vibration and acoustic, in Iran, we are enjoying the presence of great researchers and scholars, as in this conference. Iran is ranked as the 10th country in the world in this science based on the international and reliable sources. This great honor undoubtedly is the outcome of perseverance and endeavors of scholars, researchers and students of this country.
In this international conference, firstly we received 450 abstracts which lead to 280 after primary consideration. In a review process by two or three experts, 243 articles were chosen to present in the conference. 44 of these articles will be presented as a Poster-article and the rest are going to be presented in our 8 parallel sessions in the two days of conference. 145 of the accepted papers are in Farsi, and 98 have been prepared in English. Proceeding of ISAV2012 has been published on DVD, and also will be indexed in CIVILICA. The book of abstracts has been edited, printed and distributed, in order to spread further, the science and engineering of vibration and acoustics, in the society. It is intended to publish selected papers in special issues of known journals.
I want to express my thankfulness to Sharif University of Technology and the Iranian Society of Acoustics and Vibration which did so much for this conference to be occurred. My kind regards also go to the keynote speakers and authors who share us their findings and their presence makes this conference successful. The efforts of the scientific committee, the board of reviewers, and the executive committee are too much important to mention. Their indefatigable efforts made this conference real.
We hope the participants enjoy their presence in this conference and find this gathering scientifically acceptable. We invest so much hope for your presence and involvement in the next ISAV conference.

ISAV2012 Conference Chairman

Dear colleagues
On behalf of 230 members of Iranian Society of Acoustics and Vibration (ISAV), I would like to extend my warm welcome to all participants of the 2nd International Conference of Acoustics and Vibration (ISAV2012) , hold on 26-27 December 2012 in Tehran, Iran.
The Conference is an annual event organized by the Iranian Society of Acoustics and Vibration (ISAV) and Sharif University of Technology. With your participation, I believe ISAV2012 would contribute greatly to scientific achievements on sound and vibration. Human network is the key factor to success of the development of the new technologies. Recently ISAV2011 has been successful in bring experts in sound and vibration for the active technical and personal exchanges. We hope that ISAV2012 inherits the tradition and success of previous ISAV conference. Your presence at ISAV2012 is thus most valued and I am sure that you will consider your attendance as a most interesting experience.
I would like to thank all members of organizing committee, advisory and scientific committees, session chairs, reviewers and authors for their valuable efforts and active participation. They all worked hard to bring high quality technical program. Also, I greatly appreciate government and industry sponsors for their generous support. I extend my thanks to the ISAV2012 secretariat, for their excellent administrative management.
I wish you a very fruitful and enjoyable time.
