SOCIETY
All enquiries should be addressed to the Secretary, British Acoustical Society, 1 Birdcage Walk, London S.W.1 (Telephone: 01-930 7476). 1. MEETINGS
IO-14 January 1972, at Institute of Sound and Vibration Research, University of Southampton, a symposium on “Flow duct acoustics”. Current research on propagation and attenuation of moderate and high-amplitude sound in ducts carrying flow will be discussed, with emphasis on problems important in aero-engines, heating and ventilating systems and nuclear reactor heat exchangers. Joint meeting with the American Society of Heating, Refrigeration and Air Conditioning Engineers. Details from: Professor P. E. Doak, I.S.V.R. The University, Southampton SO9 5NH. 24 February 1972, 3.15 p.m., Royal Festival Hall, London, a meeting on “Concert hall acoustics with special reference to the Royal Festival Hall”. The emphasis will be on “assisted resonance” and allied work, with discussion of other aspects of concert hall acoustics. Joint Meeting with the Institute of Physics Acoustic Group. Details from: Mr P. H. Parkin, Building Research Station, Garston, Watford WD2 7JR. 23 March 1972, Chelsea College of Science and Technology, London, a meeting on “Macrosonics”. The development and application of high intensity ultrasonics. Joint meeting with the Institute of Physics Acoustics Group. Details from: Dr R. W. B. Stephens, 49 West Hill Road, London S.W.18. 27-28 March 1972, University of Loughborough, a meeting on “Non-linear dynamics”. Methods of analysis of non-linear dynamic systems-correlations with experiment, special relevance to aeronautical structures and control systems and interactions. Details from: Professor D. J. Johns, Department of Transportation Technology, The University, Loughborough, Leicestershire. 5-7 April 1972, University of Loughborough, Spring Meeting of the Society. Lectures of general interest and specialized sessions covering aerodynamic noise and ultrasonics in industry. The Rayleigh Addresses will be given at the meeting and the Rayleigh Gold and British Acoustical Society Silver Medals presented. The Annual Dinner of the Society will take place during the meeting. Details from: Professor J. W. R. Griffiths, The University, Loughborough, Leicestershire. 17-19 April 1972, I.S.V.R., University of Southampton, a meeting on “Applications of experimental and theoretical structural dynamics” to bring together people who are concerned with problems of structural dynamics in industry, research establishments and universities. Details from: Dr F. J. Fahy, I.S.V.R., The University, Southampton SO9 5NH. 20 April 1972, 10.00 a.m., University of Newcastle on Tyne, a meeting on “Impulsive noise”. Characteristics, hearing damage risk, subjective effects and measurements of impulsive noise. Details from: T. Smith, 41 Valley Gardens, Monkseaton, Whitley Bay, NE25 9AQ. i
