(author), Technisch Physische Dienst TNO - TH (author)High Reynolds number, low Mach number gas flows in pipe systems with closed side branches exhibit spectacular low frequency self-sustained pulsations driven by periodic vortex shedding at specific values of the Strouhal number. A detailed study is presented of the behaviour of the flow in a system with two opposite closed side branches of equal...article 1995

Vos, J. (author), TNO Technische Menskunde (author)The present paper addresses the annoyance caused by impulse sounds produced by small firearms. Spectrally, these sounds are characterized by relatively high sound pressure levels for frequencies between about 100 and 3000 Hz. In the present literature review, the results from field, laboratory, and field-laboratory studies are considered. In all...conference paper 1995

Otten, L.J. (author), Gaillard, A.W.K. (author), Wientjes, C.J.E. (author), TNO Technische Menskunde (author)Event-related brain potential (ERP), heart rate (HR), and blood pressure (BP) responses were examined during the 6s foreperiod of a choice-reaction task. Low and high trait-anxious males were required to make same/different judgements based on the similarity of two successively presented visual patterns. The pitch of a warning tone, presented at...article 1995

Vos, J. (author)Onset asynchrony has been put forward as one of the relevant factors in auditory scene analysis (for references, see A.S. Bregman, MIT Press, Cambridge, 1990). In the present study this issue was further investigated using a new paradigm: musically trained subjects were presented with two successive pairs of simultane-ous complex tones and they...article 1995

de Jong, R.G. (author), Miedema, H.M.E. (author), TNO Preventie en Gezondheid (author)In the Netherlands a new freight-only railway route, the "Betuweroute", is being planned to carry freight traffic from Rotterdam harbour east into Germany. Inhabitants of areas near the future route are concerned about noise and vibration, and question the relevance of current legislation for a "freight-only" line. An analysis of field surveys,...article 1996

de Lange, P.A. (author), van Luxemburg, L.C.J. (author), Muchall, R.C. (author), TNO Bouw (author)The first opera house ever to be built in the Netherlands opened its doors on 26 September 1986. Erected in the heart of old Amsterdam, the building houses the Dutch Opera Company, the National Ballet and the Ballet Orchestra. The design and planning of the building has an interesting history. The original architect, Mr. B. Bijvoet, drew up his...conference paper 1996

Vos, J. (author), TNO Technische Menskunde (author)In a previous study on the annoyance caused by shooting sounds [Proceedings Internoise '96, Vol. 5, 2231-2236], it was shown that an almost perfect prediction of the annoyance, as rated indoors with the windows closed, was obtained on the basis of the weighted sum of the outdoor A-weighted and C-weighted sound exposure levels [ASEL (LAE) and...conference paper 1998

Salomons, E.M. (author), Technisch Physische Dienst TNO - TH (author)The numerical implementation of the Green's function parabolic equation (GFPE) method for atmospheric sound propagation is discussed. Four types of numerical errors are distinguished: (i) errors in the forward Fourier transform; (ii) errors in the inverse Fourier transform; (iii) errors in the refraction factor; and (iv) errors caused by the...article 1998

Hall, M. (author), Smeele, P.M.T. (author), Kuhl, P.K. (author), TNO Technische Menskunde (author)The integration of auditory and visual speech is observed when modes specify different places of articulation. Influences of auditory variation on integration were examined using consonant identifi-cation, plus quality and similarity ratings. Auditory identification predicted auditory-visual integra-tion. Multi-dimensional scaling (MDS)...conference paper 1998

Vos, J. (author), Buchta, E. (author), TNO Technische Menskunde (author)A few years ago, Schomer [Noise Control Eng. J. 42(5), 179-191 (1994)] developed a new rating procedure for high-energy impulsive sounds, in which a level-dependent conversion of the C-weighted sound exposure levels (CSELs) of the impulses into A-weighted sound exposure levels (ASELs) of equally annoying vehicle sounds was applied. In a recent...conference paper 1998

Also, for the same respondents, the subjective effects of (local) road...conference paper 1998

Steeneken, H.J.M. (author), Houtgast, T. (author)Current objective measures for predicting the intelligibility of speech by an index assume that this can be obtained by simple addition of the contributions of individual frequency bands. The Articulation Index (AI, and the related Speech Intelligibility Index), and the Speech Transmission Index (STI) are based on this assumption. There is...article 1999
