En los últimos años, la mayoría de los grandes partidos políticos de España han venido haciendo alusión a los problemas originados por los impactos acústicos y los diversos malestares sonoros sufridos por muchas personas en nuestras ciudades. Esta presencia del tema, explicada por el aumento de la conciencia social respecto a este problema, se ha graficado en una serie de manifestaciones y reacciones políticas, expresadas tanto por escrito como de forma oral, en actos públicos y privados. La mayoría de las veces, esta toma de conciencia ha sido recogida y difundida a través de los programas políticos electorales convirtiéndose, así, en algo más que un simple compromiso político, llegando también a ser un medio de análisis externo del nivel de implicación político-institucional en el problema, y posteriormente, también en un medio para el seguimiento de variables como el grado de cumplimiento de las medidas recogidas en los "prometidos" programas, su eficacia o sus resultados. Así, hemos decidido realizar un estudio basado en las últimas elecciones municipales andaluzas (2011) para analizar el comportamiento, posiciones y alternativas resolutivas que sobre la contaminación acústica han dado los principales partidos políticos andaluces, a los ciudadanos y a los diversos agentes sociales que convergen en la esfera urbana. ; Over the last years, the three main political parties have been alluding to the problems caused by acoustic impacts and different noise discomforts suffered by many people in the urban areas of Andalusia. This circumstance, partly explained by an increasing social awareness regarding this issue, has led to a series of demonstrations and political reactions, expressed both in written and oral means, in public and private events. Most of the time, these have been collected and diffused through the electoral programs, not only as a mere political commitment but also as a way of external analysis of the political-institutional involvement level in the problem. They can also be understood as a ...

The article is the result of several surveys, conducted with different methods around nearby noise. As the failure of the building makes it impossible for the tenant living in HLM to delimit a place of his own, he will have to play with the land imposed on him, use him to gain private space but also be able to use the noise of others to say, defend himself and be located in the community. ; International audience ; The article is the result of several surveys, conducted with different methods around nearby noise.

La défaillance du bâti ne permettant pas au locataire vivant en HLM la délimitation d'un lieu propre, il va devoir jouer avec le terrain qui lui est imposé, ruser pour se gagner un espace privé mais aussi pouvoir utiliser le bruit des autres pour dire, se défendre et se situer dans le collectif.

In recent decades, the microelectronics industry has experienced a wide democratization of the use of telecommunication applications. The improved process design and manufacturing have produced complex and high performance analog, mixed and radio frequency circuits for these applications. However, the test cost of these integrated circuits still represents a large part of the manufacturing cost. Indeed, very often, analog testing is not just a functional test but needs measurements for specification validations. These measurements require the use of dedicated instruments expensive resources on standard industrial test equipment.One of the essential but costly specifications to validate in RF circuitry is the phase noise level. The currently used industrial technique consists in capturing the signal from the circuit under test using an RF tester channel equipped with a high performance analog to digital converter; a Fourier transform is then applied to the digitized signal and the phase noise is measured on the resulting spectrum.The approach proposed in this thesis is to achieve the phase noise measurement using solely digital low-cost resources. The basic idea is to perform 1-bit capture of the analog signal with a standard digital channel and develop post-processing algorithms dedicated for phase noise evaluation from the zero-crossings of the signal.Two methods are presented. The first method is based on an estimate of the instantaneous signal frequency and an analysis of their dispersion induced by phase noise. This method imposes a strong constraint on the sampling frequency to be used and proved to be sensitive to noise amplitude, limiting the range of possible measures. A second method is then proposed to overcome these limitations. From the binary capture of the analog signal, a reconstruction of the instantaneous phase of the signal is carried out, then filtered and characterized by a common tool of frequency stability assessment: the Allan variance. This technique, robust to amplitude noise and jitter, ...
