The uncertainty increases rapidly and for very low frequencies it goes toward infinity. This paper approaches this issue and presents a unique way to verifying and calibrating the low-frequency response of measurement microphones. Using a small isolated calibration volume and applying a constant force to a large piston inside this volume, you obtain a direct proportional relation between force and sound pressure, allowing calibration of measurement microphones down to 0.01 Hz.Fri Jan 27 14:10:42 CET 2012Journal of Sound and Vibration203-214Annoyance from simulated road traffic noise651979imported A laboratory study was carried out to investigate the relation between road traffic noise and annoyance with special reference to the number of noisy events. Each noise condition lasted 30 minutes and consisted of pink noise which was shaped with respect to frequency and time in order to simulate cars and trucks passing by on a nearby road. The noise levels of the stimuli, measured as Leq, were within the range 40 to 70 dB(A). Subjects were exposed to each noise condition in groups of five, after which their reactions were assessed by using a questionnaire. Annoyance was found to be highly correlated with the noise level measured as Leq or LNP. Various time-derivative-based annoyance prediction methods were also used, and some of them yielded promising results. There are indications, however, that the time-derivative-based methods suffer from a major drawback. When the results from this experiment are combined with those from previous investigations, some light is thrown on the possibility of improving Leq as a general noise annoyance measure.Fri Jan 27 14:10:42 CET 2012Applied Acoustics373-385Sound insulation between dwellings – Requirements in building regulations in Europe712010717 Building Descriptors; Dwellings; ISO Sound insulation regulations; requirements; In most countries in Europe, building regulations specify sound insulation requirements for dwellings. The requirements are expressed by descriptors defined in standards. Within building acoustics, ISO standards are implemented as European (EN) standards and national standards.Sufficient sound insulation between dwellings is important to protect against noise from neighbours and to provide privacy and possibilities for activities without causing annoyance. In 2008 a comparative study investigating the legal requirements for sound insulation between dwellings was carried out. This paper is a result of that study and describes and discusses the main requirements for airborne and impact sound insulation in 24 countries in Europe. The comparison shows considerable differences in terms of descriptors, frequency range and level of requirements.It is concluded that regulatory sound insulation requirements need tightening in some countries. As a starting point for further discussion, suggestions for airborne and impact sound insulation criteria providing “standard” and “increased” comfort are given. While tightening regulations implies a growing need for exchange of information and experience, the diversity in Europe creates difficulties for efficient cooperation, and harmonization of descriptors is needed. The benefits of harmonizing descriptors include facilitating the exchange of construction data, design details and development of design tools. Based on experience, legal requirements and classification criteria could be adjusted and optimized.It is proposed to establish cooperation in Europe and to prepare an “acoustical” housing directive with a related strategy paper “Research for quieter European homes in 2020” in the same way as with European initiatives for environmental noise. The noise issue has also received increasing attention from WHO. In a large analysis of European housing coordinated by WHO, neighbour noise was identified as a health problem, and reduction of noise exposure in the home was included in the proposed main objectives for a housing policy.This paper is one of two related papers about sound insulation of dwellings, dealing with requirements and descriptors in building regulations in Europe. This paper focuses on requirements, the other paper, [1], focuses on descriptors for requirements, including suitability considerations, one of them being the correlation with subjective evaluation.Wed Jan 25 15:36:53 CET 2012Water Resour. Res.112875--2883Prediction Uncertainty in Seasonal Partial Duration Series271991POT Seasonal In order to obtain a good description of the exceedances in a partial duration series it is often necessary to divide the year into a number (2–4) of seasons. Hereby a stationary exceedance distribution can be maintained within each season. This type of seasonal models may, however, not be suitable for prediction purposes due to the large number of parameters required. In the particular case with exponentially distributed exceedances and Poissonian occurrence times the precision of the T year event estimator has been thoroughly examined considering both seasonal and nonseasonal models. The two-seasonal probability density function of the T year event estimator has been deduced and used in the assessment of the precision of approximate moments. The nonseasonal approach covered both a total omission of seasonality by pooling data from different flood seasons and a discarding of nonsignificant season(s) before the analysis of extremes. Mean square error approximations (bias second order, variance first and second order) were employed as measures for prediction uncertainty. It was found that optimal estimates can usually be obtained with a nonseasonal approach.Tue Jan 24 00:00:00 CET 2012GLOBECOMconf/globecom/20111-5Error Floor Analysis of LT Codes over the Additive White Gaussian Noise Channel.2011dblp Wed Jan 18 11:59:19 CET 2012Risk Management in a Dynamic Society: a Modeling Problem: Safety Science Vol. 27, No. 2/31997imported Sun Jan 15 00:00:00 CET 2012NeuroImage116-25Developmental cortical thinning in fetal alcohol spectrum disorders.582011dblp Fri Jan 13 15:46:47 CET 2012Water Resour. Res.113001--3010Prediction in partial duration series with generalized pareto-distributed exceedances281992GPD Extremes POT As a generalization of the common assumption of exponential distribution of the exceedances in partial duration series the generalized Pareto distribution has been adopted. Estimators for the parameters are presented using estimation by both method of moments and probability-weighted moments. The corresponding estimators for the T-year event are given and approximate expressions for bias and variance of the estimators are derived in both cases. Using the mean square error of the T-year event estimator as a performance index it is shown that the method of moments is preferable to the probability-weighted moments. Maintaining the generalized Pareto distribution as the parent exceedance distribution the T-year event is estimated assuming the exceedances to be exponentially distributed. For moderately long-tailed exceedance distributions and small to moderate sample sizes it is found, by comparing mean square errors of the T-year event estimators, that the exponential distribution is preferable to the correct generalized Pareto distribution despite the introduced model error and despite a possible rejection of the exponential hypothesis by a test of significance. For moderately short-tailed exceedance distributions (with physically justified upper limit) the correct exceedance distribution should be applied despite a possible acceptance of the exponential assumption by a test of significance.Fri Jan 13 00:00:00 CET 2012IACR Cryptology ePrint Archive129Distance Hijacking Attacks on Distance Bounding Protocols.20112011dblp Thu Jan 12 00:00:00 CET 2012ARIST191-124Indexing and retrieval for the Web.372003dblp Thu Jan 12 00:00:00 CET 2012Scientometrics2687-699Trend and efficiency analysis of co-authorship network.902012dblp
