Invitation to the


1997 INTERNATIONAL CONGRESS on
NOISE CONTROL ENGINEERING and
INTERNATIONAL SYMPOSIUM on
ACTIVE CONTROL OF SOUND AND VIBRATION

Dear friends,

On behalf of the Board of Directors of International INCE, the sponsoring institutions: the European Acoustic Association, the Hungarian Academy of Sciences and various Hungarian governmental bodies, the Scientific Society for Optics, Acoustics, Motion Pictures and Theatre Technology as the hosting society, as well as all members of the organizing committees of

ACTIVE 97 and INTER-NOISE 97, we are delighted to extend you our warmest invitation to join the 26th INTER NOISE Congress and in the new series of meetings on active control which began in Blacksburg, Virginia, USA and Tokyo, Japan, and became ACTIVE 95 in New Port Beach, California, USA in 1995.

On the basis of the number and quality of abstracts submitted – more than 490 from 48 countries for INTER-NOISE 97 and more than 120 from 29 countries for ACTIVE 97 – the technical programs of the two conferences promise to contain valuable engineering and scientific information.

Although the number of papers to be presented point to rather intensive working days, all efforts are being made to ensure that delegates have opportunities to enjoy the social program that is being arranged.

Budapest is a city with an interesting history, a unique atmosphere, and an exciting future. The congress venue has a special place in the capital: it is located right on the bank of the Danube, which crosses Budapest dividing it into two parts, Buda and Pest. All of us who are involved in the organization very much are looking forward to acting as hosts to these important events. We hope that all participants, delegates and accompanying nondelegates, will find their stay useful and fun and enjoy the traditional Hungarian hospitality.

We are looking forward to seeing you all in Budapest.

    CONGRESS / SYMPOSIUM INFORMATION

    General

    Last year, Hungary celebrated the 1100th anniversary of its founding in the Carpatian basin. Among the almost 200 countries of the world, Hungary is one which, due to the geographic size and economic potential, cannot be considered a major power. Its place is in the heart of Europe, its role being a bridge between West and East. This geopolitical situation, extensive developing relations, and tourist attractions have aroused the interest in the Republic of Hungary. Hungary ranks among the top tourist destinations in Central and Eastern Europe; the country welcomes more than 20 million tourist each year. What makes Hungary attractive for foreign visitors? It is a mixture of different factors: our ancient culture; our particular climate, unique to the Carpatian Basin, which produces succulent fruits and vegetables of a quality unsurpassed in the world; our integration of various cultures and cuisines; Hungary, the „Queen of the Danube”, plus other historical cities. And then there is Lake Balaton, „the Hungarian Sea”; the famous „puszta”, the most westerly open steppe in Europe; the excellent opportunities for hunting, fishing and horseback riding; our folklore and traditions; our rich music culture, and abundance of thermal waters, one of our unrivaled resources. Budapest has long been famous not only as a splendid capital city but a splendid spa, with 123 springs yielding 50,000 cubic meters of thermal water daily for use in baths and thermal hotels for both therapy and recreation.

    Another special attraction is the caves, many of which can be visited – for example the Szemlõhegy and the Pálvölgy caves. When you come to Hungary, your greatest experience will be meeting people who are easy-going and friendly; almost everyone in the tourist business speaks English and/or other foreign languages.

    Budapest is the political, administrative, social, economic, scientific, and cultural centre of the country. The visitor finds the capital a vibrant, cosmopolitan metropolis with a colorful nightlife and shops of almost every description. The city is a harmony of fascinating contrasts: ruins bear witness to its 2,000-year past alongside modern buildings; there are organ concerts and operettas; religious services and casinos; luxurious meals with gypsy music, and fast food snacks; fairs and festivals; deluxe downtown hotels and accommodations provided in bucolic settings.

    Photo of Fishermen's Bastion A few Budapest highlights: Buda Castle, featuring a magnificent Danube panorama, which is part of UNESCO's World Heritage registry and includes the Hungarian National Gallery, Matthias Church, and Fishermen's Bastion . Not to be missed are Gellért Hill ; Margaret Island ; the Chain Bridge ; the Parliament ; the Opera House ; Heros' Square , featuring the Millenium Memorial , the Museum of Fine Arts , the Palace of Exhibitions , and, directly behind the square, the City Park , where one can find Vajdahunyad Castle and Széchenyi Baths, welcoming about 150 large-scale congresses and conferences yearly.

    Conference venues and social events

    ACTIVE 97 will be held at School of Public Administration (Budapest XI. Ménesi út 5.) which is situated on the foothills of Gellért-Hill. The location is a quiet, green island within a stone's throw of the pulsating heart of Buda, the western part of the two parts of Budapest. The location is still within walking distance of most hotels and the venue of INTER-NOISE.

    The two events, ACTIVE 97 and INTER-NOISE 97, begin on August 20 with an optional pre-congress program, a river cruise on the Danube. Dinner will be served and participants will be able to enjoy the fireworks on the occasion of St. Stephen's Day. (Participation may be limited).

    On August 21 there will be a welcome drink at the venue of ACTIVE 97 (price included in the participation fee).

    The symposium dinner (optional) will be held in a traditional Hungarian village environment, offered by the Open Air Museum at Szentendre, 20 km North from Budapest.

    INTER-NOISE 97 will be held at the Technical University of Budapest – TUB – (Budapest XI. Mûegyetem rkp. 1-3.) which is situated on the banks of the Danube. The central building has a special historical atmosphere; it is an exciting environment because of the thousands of students who attend the University. Picture of Technical University of Budapest

    INTER-NOISE registration will begin at noon on August 24. Participants completing the registration till 16.00 are invited to a 2 hours sightseeing-tour, free of charge.

    The exhibition will officially open at 18.30 on August 24.

    The Opening Ceremony begins on August 25 09.30, and will be followed by the first distinguished lecture. The Welcome party will be held just after the afternoon sessions (price included in the participation fee).

    The Congress Banquet (optional program) will take place in the evening of August 26 in one of the most attractive palaces of Budapest.

    The Congress will conclude with a Closing Ceremony in the afternoon of August 27 in the main aula of the TUB (price included in the participation fee).

    CURRENCY INFORMATION

    The unit of currency is the Forint (Ft. or HUF). We suggest that you do not change too much money before arriving in Budapest. All major currencies can be exchanged at a number of places such as the airport, railway stations, exchange offices, hotels or banks. The exchange rate is more advantageous in Budapest, especially in larger banks in the city centre, than in your home country. You can also pay by credit card at the hotels, in good restaurants, at pump stations and even at large supermarkets. Even though all major credit cards are welcome in Hungary, the most popular ones are EuroCheck, Visa or EuroCard/MasterCard.
