A note on the objective measurement of road traffic noise
Noise 1.4.99(54995) Lehmann, R. The determination of noise discomfort. (In French with English Summary). Revue d'Acoustique, 1969, 2.5, 37-46; abstr, in Building Science A b stra ct s Presents some results of the studies undertaken since 1957 by the Acoustics Technical Committee of the International Organization for Standardization (ISO) in the field of noise discomfort. The problems discussed here concern noise b o t h inside and outside the building and deal with the determination o f a system of curves defining the noise discomfort. Characteristics of noise annoyance are also given. 1.4.100(54996) Reichardt, W., Notbohm, K. and Jurseh, H. Improvement of the Niese m e t h o d to calculate loudness levels. (Verbesserung des Lautstarkeberechnungsverfahrens nach Niese). (In German). Acustica, 1969, 21.3, 134- 143 Starting from experiences with the Niese method of calculating loudness levels, improved rules for the calculation and new nomograms for the determination of additional constants have been developed, by evaluating a large number o f new subjective loudness measurements. Statistical characteristics (standard deviation and range of reliability) are determined for the correlation between the results obtained by the Zwicker, Stevens and the improved Niese method of calculating loudness levels and the subjective judgements. 1.4.101(54997) Scholes, W. E. and Vulkan, G. H. A note on the objective measurement of road traffic noise. Applied Acoustics, 1969, 2.3, 185-197; abstr, in Building Science Abstracts Summarizes aspects of noise measuring technique that are becoming generally adopted, and gives a bibliography of recent publications on traffic noise. 1.4.102(54998) Schreiber, L. On the calculation of the energyequivalent continuous sound level traffic noise from a street. (Zur Berechnung des Energie-Aquivalenten Dauerschallpegels der Verkehrsgerausche yon einer Strasse). (In German) Acustica, 1969, 21.2, 1 2 1 - 1 2 3
The equivalent continuous sound level is calculated as a function of sound level, speed, and density of vehicles for an ideal street model. A very simple approximate formula is obtained for real streets, because the raising o f the sound level with increasing speed of the individual vehicles approximately compensates the effect of the shorter period of influence. 1.4.103(54999) Stone, R. B. Cockpit noise environment of airline aircraft. Aerospace Medicine, 1969, 40.9, 989-993 Noise level surveys were carried out in the cockpit of the M404, DC6, F27A and J, F227, CV580, CV600, L188, B720, B727, B707, and DC9. Octave band analysis during a number of regimes of flight indicate cruise and high speed descent were the noisiest portion of flight. Comparison of data with damage risk and speech interference criteria demonstrates that many of the currently operated turboprops exceed damage risk criteria. Many of the aircraft, including newer jets, cause communication between pilots to be carried out at a near shout. A noise level criteria for airline cockpits adopted by the Air Line Pilots Association is presented. Noise measurements obtained in the cabin of a number of these aircraft are included for those interested.
Specialised and protective equipment 1.4.104(55056) Edwards, G. Will air-bags cut car deaths? Engineering, 19 70, 209.541 O, 6 - 37 American legislators may well insist on the fitment of 'Safety air-bags' in new cars b y 1972. These would cushion passengers in a serious crash and should provide even greater protection than seat-belts. Automatic bag inflation provides automatic protection.

Relations at Cornell University, 1969, 4.10, 165pp; abstr, in Training Abstracts Designed as a ready reference source on training practices and theories in work organisations, this annotated bibliography cites one hundred and nine items on general aspects of training (including the historical development o f training and the identification of needs), followed by eleven bibliographies and b y over six hundred other works on manual and clerical skill training, technician and engineering training, supervisory training in industrial and clerical settings, organisational planning and management development, specific training methods and techniques, audiovisual aids, manpower planning and development, the evaluation of training programmes, and United States Manpower policy. A n author index and a periodical and publisher index also appear. 1.4.106(55073) Warren, M. W. Training for results: a systems approach to the development of human resources in industry Addison-Wesley Publishing Co. Inc.; Jul. 1969; abstr, in Training Abstracts Using the systems approach, this b o o k explores training in industry as an an organisational tool for the development o f human resources and stresses training results and return on investment, rather than training programmes. It includes sections on cost estimating and evaluating training in terms o f objectives and results. The book is intended to serve as a guide to general management personnel and industrial relations directors, and training directors on how training functions; how and when it is cost effective; how to evaluate it; and how it should be structured within the organisation. Problems encountered in industrial, administrative, sales, supervisory, and technical training fields are discussed. The systems approach is used because of its emphasis on training as a cost effective management tool and its use of training as a way of obtaining a measurable behaviour change. Contents - Training as a system. Elements of a training system. Analysis of training needs. Selecting a training method. Estimating costs. Instructional design. Evaluating training actions.
