These guidelines are divided into three sections:

A1. PURPOSE

The purpose of the International Commission for Acoustics (ICA), is to promote international development and collaboration in all fields of acoustics including research, development, education and standardisation.

Means for the Commission to fulfill its mission are:

a) to maintain close contacts with national and regional acoustical societies and associations as well as other relevant professional organisations and seek consensus in matters of mutual interest.

to provide an information service on societies, congresses, symposia, etc., research and education organisations in the field of acoustics.

to take a pro- active role in co-ordinating the main international meetings within acoustics .

b) to convene the International Congresses on Acoustics in accordance with the Commission's guidelines and to act as the International Advisory Committee for these congresses.

c) to sponsor or co-sponsor other topical and special international conferences normally in close cooperation with national and/or regional organisations and to give financial support (grants or guarantees), as a grant to organising committees for such meetings or as a travel grant to participants.

A2. INVITATION TO ORGANISE THE INTERNATIONAL CONGRESS

The International Commission for Acoustics (ICA) initiates and sponsors International Congresses in countries of its Member Societies. There is a long planning cycle for every International Congress on Acoustics. Based on proposals to hold future congresses, the Commission Board invites a member society to undertake the organisation of a congress.

The final decision by the Board to extend an invitation is made six years in advance.

In these guidelines, C is the year during which a future International Congress is to be held. The preceding year is identified as C-1, etc. These guidelines describe the events and data that have to be prepared and presented to the Commission Board and to others.

A3. RESPONSIBILITIES

All legal and financial responsibilities in connection with the International Congress on Acoustics rest with the Member Society which has accepted the invitation to organise the Congress.

Member Societies are invited to make proposals to the Commission Board to host the International Congress on Acoustics. A Member Society may be selected as a host if the professional acoustical activities in the potential host country are sufficiently well-developed that active participation by 800 or more registrants at the International Congress can reasonably be expected.

Early proposals may have the form of a letter of intent. The final proposal on which the Board's decision in year C-6 will be based, must be complete. A representative for the inviting society is expected to present the proposal to the Board.

Information to be included in the final proposal:

High priority items include: the proposed site (e.g. a hotel, university or conference center), the proposed dates with possible alternatives, the expected number of registrants, the availability of local society members who could support the running of the Congress, the name of the proposed General Chairman, the name of the Technical Programme Chairman and tentative budget information including estimated congress fee, hotel cost information and travelling information for participants.

Lower priority items include: information about tours, tourist attractions and other commercial features near or in the vicinity of the proposed site of the congress.

The following sub-sections give detailed information on the requirements of the International Congress on Acoustics.

The dates of the International Congress shall be chosen so as not to conflict with or overlap other major international meetings on acoustics. Conflicts with major religious holidays as well as national festivals and bank holidays should also be avoided, if possible.

It is important to choose the dates and the meeting place so that hotel expenses for participants are reasonable. This means that it may be necessary to hold the congress in an off-season for tourist travel, rather than during peak vacation periods. Negotiations with the hotels are important so that the congress can offer/guarantee the lowest prices to the participants.

The duration of the International Congress on Acoustics is limited to five days, normally starting on a Monday.

The anticipated number of registrants - all of whom are supposed to pay the same fee with possible exception for students not presenting papers and/or getting the proceedings - is of utmost importance for the planning of the International Congress on Acoustics, but it is a number that is difficult to estimate in advance of a Congress. The budget as well as the number and sizes of meeting rooms depend on this figure. It is important to make a qualified guess. If the estimate is for N active registrants, excluding exhibitor personnel and accompanying persons, it is wise to have a budget which will break even (no deficit or surplus) with revenues from 0.75N registrants and an arrangement of meeting rooms which is sufficient to accommodate 1.5N registrants.

B2. ACTIONS REQUIRED DURING YEAR C-6

During year C-6, one or more Member Societies present their formal proposals to the Commission Board to host a future International Congress. The printed versions of the proposals are normally mailed to the members of the Board in advance of the Board meeting so that they may familiarise themselves with its contents. The decision on the venue for the International Congress is made at the annual meeting of the Commission Board.

B3. ACTIONS REQUIRED DURING YEAR C-5 - C-1

The General Chairman of the International Congress (or his designated representative) is obligated to attend the annual meetings of the Commission Board in years C-5 - C. At these meetings, the General Chairman shall make presentations concerning the planning for the International Congress.

However, experience shows that such information may never be distributed. Therefore, it is recommended to follow up this distribution by direct contact with each society or to choose other direct ways of distributing the congress information.
