Full textCurrently, to put a vehicle on market, car manufacturers must comply to a certification test of exterior noise. The regulation of the United Nations Economic Commission for Europe, ECE R51-03, specifies permissible levels a rolling motor vehicle can emit. This regulation is applied since July 1st, 2016, to replace the old regulation ECE R51-02 (test method change and tightening of permissible levels). The drastic reduction in noise levels will be done in 3 steps: from 74 dB (A) under the old regulation to 68 dB (A) in 2024. Therefore, manufacturers as well as their suppliers will face a great challenge to achieve this goal. The objective of this thesis is to develop an aid to the modeling of the pass-by noise of a vehicle, as called for in regulatory testing. The goal is to predict and evaluate accurately the noise emissions earlier in the vehicle development cycle, i.e. before the industrialization stage. We must then seek a trade-off between accuracy of estimates, sensitivity to parameters, robustness of the method and numerical efficiency

Full textThe study detailed in this manuscript is part of the effort to characterize the noise emission from road vehicles. We wish to identify the noise sources of a moving vehicle, when driven on a roadway in real-world conditions, with roadside acoustic measurements. The current acoustic imaging methods do not provide sufficient performance on road vehicles. A state of the art led to the selection of an existing method, MSA-PSF, which consists in deconvolving signals from mobile sources in the frequency domain under certain assumptions, and was originally developed for aeroacoustics. This method is adapted here to the context of road vehicles. Then, an original approach is proposed in order to tackle the specific constraints of this context: CLEANT. This is an iterative method, performed in time domain with a wideband approach, which takes into account the effect of sources motion and includes two parameters designed to refine the result: the loop factor and the stopping criterium. A further version of the algorithm, including a frequency filter, is also proposed and shows significant improvement in identifying secondary sources in some particular cases. An interesting point of CLEANT is the availability of the sources reconstructed time signals, which enables other types of analysis, especially the use of the coherence with signals from on-board measurements in order to separate the contributions of uncorrelated sources. MSA-PSF and CLEANT are evaluated with numerical simulations and a set of indicators to measure their source localization and quantification performance. They are then tested in a controlled laboratory conditions experiment, using a moving source. This experiment represents a first application of the methods to a practical case, involving a linear motion, two simultaneous sources and different kinds of signals (tone and wideband). They are finally compared to the classical approach of moving source beamforming, within the frame of an experiment on a road vehicle, in real-world conditions. The original approach CLEANT yields very encouraging results, and is a clear improvement from the conventional beamforming, especially at low frequency for the tested cases. Applying it to a road vehicle in real-world conditions highlights a potentially troublesome behavior of the method, and the solution brought by CLEANT's frequency filtered version, or by adapting its various parameters. The coherence with reference signals to discriminate the physical origins of the sources is also tested and underlines the role of the short duration of the signals related to the sources passing-by context

Full textNoise pollution is a major concern for residents of urban areas. To date, the European directive 2002/49/CE requires member states to represent community noise through noise maps. These are produced using the Lden (day-evening-night level) index which is also employed for dose-effect relationships in noise annoyance prediction. However, for the assessment of noise annoyance in urban areas, its relevance is often questioned. Numerous studies have shown that noise annoyance due to community noise is not solely based on the sound pressure level and other acoustical signal characteristics such as temporal and spectral features influence noise annoyance ratings. This thesis aims to improve the assessment of noise annoyance due to various road vehicle noises in cities. It is based on experiments carried out in laboratory conditions and comprises two main parts. The first addresses the enhancement of the physical and perceptual characterization of annoyance due to various urban road vehicle pass-by noises, such as buses, poweredtwo- wheelers, heavy vehicles and light vehicles. A specific focus is put on the characterization of annoyance due to powered-two-wheelers which are among the most annoying road vehicles and studied little in the existing literature. An indicator accounting for annoyance-relevant auditory attributes of urban road vehicle pass-by noises is determined: it comprises loudness, a spectral index and two modulation indices proposed in this work. In urban agglomerations, people are often exposed to road traffic in presence of a variety of other environmental noise sources. The focal point of the second part is on the prediction of total annoyance due to urban road traffic noise combined with tramway noise. In the aim of adequately characterizing total annoyance, first the perceptual phenomena involved in annoyance due to the combination of the sources are studied. Furthermore, the analysis allows for the testing of the proposed noise annoyance indicator for the characterization of urban road traffic noise. To characterize annoyance due to tramway noise, an indicator determined in a recent study is employed. Based on these indicators and the findings regarding perceptual phenomena, models for the prediction of total annoyance due to combined urban road traffic and tramway noise are proposed

Full textToday, a growing request concerning tools for allowing sound level predictions during the construction of new urban infrastructures is observed. Some of them exist, but physical phenomena taken into account have to be still improved. This is the aim of these researches, widely based on experimental approach. Due to their various physical characteristics, all the sound sources cannot be represented by the same theoretical model. They are splited in two groups : mechanical sources and human sources. In both group, each sound source cannot be individually modelled. That is why a classification is established. It is particularly the case for the mechanical sources which are distributed in four categories. This classification has been compared with those existing in some national methods. Similar results have been found. In a first step, road vehicles circulating at steady speeds, upper than 80 km/h where tyre/road noise is dominant, are modelled by omnidirectional point sources, the equivalen source heights of which have to be determined. A method based on an inverse fitting procedure performed on experimental excess attenuation results between two receivers has been implemented. Before this, the procedure was validated using an artificial pink noise sound source located at various positions. The equivalent source has always been found very close to the pavement surface which is confirmed by a study from INRETS. Sound power level can be obtained afterwards. This procedure has been applied to passenger cars, mopeds and motorcycles for urban traffic conditions including acceleration and deceleration phases. The speed ranges between 30 and 70 km/h. Sound power level predictions, for each third octave band, have been determined with a good accuracy. Concerning human sources, for which research results are rare in existing literature, two experimental campaigns allowed to test a method simulating groups of people by several omnidirectional point sources, each of them with their adequate location and sound power level spectrum. This method has been applied to school playgrounds and to a market place. Even if in the future, other types of sound sources have to be studied, these physical characteristics can already be introduced in the theoretical sound propagation model for urban areas

Full textThe subject of this study is the effect of noise and vibrations on the vigilance of drivers in monotonous driving conditions. We have realized an on-board data acquisition system for physiological and behavioural signals. We also realized an original system for assessing the driver's position in a 3 dimensional frame in real driving conditions. We have used two new original vigilance indicators in complement of traditional ones. The first one is a signal related to the orienting reflex and the second one is the tilting angle of the driver's head. A data fusion method based on KALMAN optimal filtering is applied to obtain a vigilance scale graduated between 0 and 10. Finally, we apply the analyse of variance technique to experimental results recorded on 9 subjects who drove on the highway between Lyon and Dijon. The subjects were exposed to 2 levels of noise and 2 levels of vibrations

Full textInterfaces based on speech recognition have recently become interesting as a way of improving the use of equipments inside a car. However, tuning such interfaces demands to take into account the special sound conditions in the passenger compartment. In this PhD, we focused on improving the robustness of a present speech recognition system due to be used in a very noisy passenger compartment. We focused on the tuning and use of an advanced denoising device based on harmonic regeneration (HRNR) We then looked at "specialised" models, adapted to a specific recording situation. Finally, the differences in decoding observed when using various models made us look at differences that can occur between decodings of the same words by three distinct microphones located at various places of the dashboard. A majority vote applied to decodings of recordings made by the three microphones allowed a sensible improvement of the error rate compared to the use of a single sound recording
