    El estudio del desarrollo hist贸rico del sonido permite mostrar su capacidad para transmitir no s贸lo la dimensi贸n temporal sino tambi茅n los aspectos relacionados con el espacio y el movimiento. El sonido no es un mero canal sensorial aislado, sino que en su interacci贸n con la dimensi贸n visual genera una asociaci贸n espacio-temporal indisociable contribuyendo, en el arte y en la vida cotidiana, a la construcci贸n del lugar, en un espaciotiempo dadoThe evolution of the concept of sound shows its ability to express the temporal dimensi贸n, but also aspects related to space and movement. Sound is not just another sensorial cannel, since its interaction with the visual dimensi贸n generates an undetachable association of space and time, an specific one for every moment and plac

    Esta investigaci贸n se centra en el estudio de la dimensi贸n audiovisual de la arquitectura, como aproximaci贸n intersensorial a la aprehensi贸n e ideaci贸n del espacio. Poniendo en evidencia la complejidad de la relaci贸n hombre-medio, se plantea la necesidad de desarrollar nuevas metodolog铆as y herramientas que tengan en cuenta dicha complejidad y que favorezcan el desarrollo del proyecto. Nos mueve en esta investigaci贸n la convicci贸n de que los cambios r谩pidos y profundos que caracterizan nuestros tiempos en todos los 谩mbitos, social, econ贸mico, pol铆tico鈥 entra帽an inevita-blemente nuevos modos de conocimiento y experimentaci贸n del espacio, y por tanto nuevos ejes de investigaci贸n. La creciente valoraci贸n, en todos los campos del conocimiento, de los aspectos subjetivos y sensoriales, el desarrollo de las tecnolog铆as que ha cambiado completamente nuestras relaciones interpersonales y con el entorno, las nuevas capacidades de an谩lisis, grabaci贸n y conservaci贸n y manipulaci贸n de datos y por ultimo, aunque no menos importante, la puesta a disposici贸n democr谩卢tica y global de todo el saber a trav茅s de Internet, imponen otra aproximaci贸n al hacer, concebir y vivir la arquitectura. Esta investigaci贸n se centra en un an谩lisis cr铆tico del estado de la cuesti贸n, construyendo nue卢vas redes de relaci贸n entre disciplinas, que permitan plantear la dimensi贸n audiovisual como un nuevo eje de investigaci贸n dentro de la arquitectura, poniendo en evidencia la necesidad de desa卢rrollar an谩lisis de forma trasversal e interdisciplinar. Hemos prestado particular atenci贸n a la evoluci贸n de lo sonoro y su aproximaci贸n cualitativa a la arquitectura, mostrando como el sonido, con su capacidad de introducir el tiempo y los aspectos din谩micos (el movimiento, la presencia del cuerpo鈥), no es simplemente otro canal sensorial en la aprehensi贸n del espacio, ya que su interacci贸n con lo visual genera un espacio-tiempo indisociable, propio, caracter铆stico de cada momento y lugar. A partir de este planteamiento se ha hecho una revisi贸n metodol贸gica dirigida a utilizar el reco卢rrido como herramienta de an谩lisis, que permita estudiar la relaci贸n entre el espacio, la acci贸n y la percepci贸n audio-visual, cruzando para ello los datos correspondientes a la morfolog铆a del espacio, con los datos de la experiencia perceptiva individual y con los de los usos colectivos del espacio, utiliz谩ndose finalmente el video como un herramienta, no s贸lo de representaci贸n de lo real, sino tambi茅n como instrumento de an谩lisis, que permite tomar datos (grabaciones audio, video, obser卢vaciones鈥), aislarlos, estudiarlos, clasificarlos, ordenarlos, y finalmente, restituirlos mediante el montaje. Se ha realizado una primera experimentaci贸n 鈥渋n situ鈥 que ha servido para explorar la aplicaci贸n del m茅todo, planteando nuevas preguntas y abriendo l铆neas de an谩lisis para ulteriores investigacio卢nes. ABSTRACT This research is focused on the study of the audiovisual dimension of architecture, as an in卢tersensorial approach to space apprehension and design. It is posed the necessity to develop new methodologies and tools that keep this complexity, as a contribution to the development of a project, by means of putting into evidence the sophistication of the relationship between man and media The research moves us to the conviction that the quick and relevant changes that confer a distinc-tion to these contemporary times all over the social, economic and political environments, involve, unavoidably, new ways of knowledge and experimentation on space, and therefore, new trends of research. The growing valuation of subjective and sensorial aspects all over the fields of the knowledge and the development of the technologies that have changed completely our interpersonal and environmental relationships, the new tools for analysis, recording, conservation and manipulation of data and, last but not least, the setting to democratic and global availability of the whole knowledge through Inter卢net, impose another approach to the making, conception and experience of architecture. This research deals with a critical analysis of the state鈥搊f- the-art of the matter, modelling new webs of relationship among disciplines that allow to outline the audiovisual dimension as a new focus of research on architecture, putting evidence into practice as it is necessary to develop any analysis in a transversal and interdisciplinary way. It is paid a special attention to the evolution of sound objects and their qualitative approach to ar卢chitecture, showing how sound, with its capacity to transmit time and dynamic aspects of things (movement, the presence of the body), it is not simply another sensorial channel in the apprehension of space, since its interaction with the visual thing generates an undetachable association of space and time, an specific one of every moment and place. Starting from this position a methodological revision has been made leading to use a walk as a tool for analysis that allows to study the relationship among the space, the action and the audio-visual perception, by means of crossing data corresponding to the morphology of space, with the data of a perceptive experience from the perspective of an individual observer and with those of the collective uses of the space, as video has been finally used as a tool, not only as a representation of the real thing, but also as a tool for analysis that allows to take isolated data (audio recordings, video, obser卢vations), to be studied, classified, and put into their appropriate place, and finally, to restore them by means of a multimedia set up. A first experimentation in situ has been carried out, being useful to explore a method of appli卢cation, outlining new questions and beginning with new ways of analysis for further research

    The Soundscape and Listening as an Approach to Sensuous Urbanism: The Case of Puerta del Sol (Madrid)

    This article focuses on the placemaking process and experimental research on the citizens' assessment of the soundscape in Puerta del Sol in Madrid. Numerous studies conducted in recent decades have shown that sound is a crucial element capable of providing new insights into the relationship between human beings and the environment. Sound possesses physical-sensory-perceptual qualities which connect the emotional and the rational aspects of the experience of the place, overcoming the aesthetic/scientific duality. By default, the soundscape is the result of a collective production. It is the resonant expression of the multiple activities and uses that inhabit a space. The soundscape of everyday life provides a vision of life in a particular place, giving meaning and a singular character to the fact of living there. The concept and methods of the soundscape arise from sensitive experiences of the place in direct relation to a community. This exploratory research focused on in situ methods (soundwalks, improvised interview mappings, sound archives, performances, and collective sound actions) as expressions of collective listening to place. This article also focuses on how to map and share the result of this research, the technology to build a collective digital place as a place of confluence of experiences, citizen knowledge, and reflection on the situated soundscape

    El sonido y sus m煤ltiples resonancias. Tres proyectos

    Get PDF
    Numerosos estudios en las 煤ltimas d茅cadas muestran c贸mo el sonido es un importante elemento capaz de proporcionar nuevos conocimientos sobre el entorno y sobre las relaciones entre el ser humano y el medio. El sonido posee unas cualidades f铆sico-sensoriales-perceptivas particulares, que conectan lo emocional y lo racional. Permite por tanto abordar de forma amplia el conocimiento y el an谩lisis de algo tan complejo como la experiencia y la vivencia del lugar. Hoy asistimos a un fuerte desarrollo de m茅todos, herramientas y estrategias de intervenci贸n en el entorno con el paisaje sonoro como protagonista. Como producto de una colectividad, el paisaje sonoro se sit煤a en un lugar privilegiado en el pensamiento contempor谩neo. Sus conceptos y m茅todos sonoros surgen a partir de experiencias sensibles del lugar en relaci贸n directa con una comunidad. La utilizaci贸n de m茅todos聽in situ聽(recorridos, cartograf铆as, archivos sonoros, performances y acciones sonoras colectivas) en este 谩mbito son expresiones de gran inter茅s generadas alrededor de la escucha colectiva del lugar. Estos estudios muestran la importancia de los aspectos sensoriales y c贸mo a trav茅s del sonido y la escucha se da una reapropiaci贸n del espacio, de nuestro entorno, del reconocimiento del otro y del lugar. Presentamos tres proyectos de investigaci贸n con la complejidad del ambiente sonoro como elemento com煤n. Estos proyectos se centran en tres situaciones diferentes, el periodo de la COVID-19, el estudio de paisajes sonoros hist贸ricos, y el estudio del ambiente sonoro contempor谩neo. Estos trabajos ponen un foco de inter茅s particular en la complejidad de las percepciones y relatos de los ciudadanos como fuente de conocimiento

    Realizar un recorrido sonoro y sensorial coordinados entre Francesc Daumal, Cristina Palmese y Francesco Careri, era algo excepcional. El primero por su inter茅s por la ac煤stica arquitect贸nica, la segunda por su contribuci贸n sobre la arquitectura sonora y sensorial, y el tercero por la transgresi贸n del usual 鈥渄ominio鈥 espacial que siempre impulsa. Estamos convencidos de que todos los que realizamos este recorrido dentro y fuera del campus lo recordaremos con verdadera ilusi贸n. Para nosotros, contribuy贸 a entender que la ense帽anza en cualquier 谩mbito, debe continuar rompiendo los antiguos moldes.Postprint (published version

    Redshift distributions of galaxies in the Dark Energy Survey Science Verification shear catalogue and implications for weak lensing

    We present photometric redshift estimates for galaxies used in the weak lensing analysis of the Dark Energy Survey Science Verification (DES SV) data. Four model- or machine learning-based photometric redshift methods鈥擜NNZ2, BPZ calibrated against BCC-Ufig simulations, SKYNET, and TPZ鈥攁re analyzed. For training, calibration, and testing of these methods, we construct a catalogue of spectroscopically confirmed galaxies matched against DES SV data. The performance of the methods is evaluated against the matched spectroscopic catalogue, focusing on metrics relevant for weak lensing analyses, with additional validation against COSMOS photo-z鈥檚. From the galaxies in the DES SV shear catalogue, which have mean redshift 0.72 0.01 over the range 0.3 < z < 1.3, we construct three tomographic bins with means of z 录 f0.45; 0.67; 1.00g. These bins each have systematic uncertainties 未z 鈮 0.05 in the mean of the fiducial SKYNET photo-z n冒z脼. We propagate the errors in the redshift distributions through to their impact on cosmological parameters estimated with cosmic shear, and find that they cause shifts in the value of 蟽8 of approximately 3%. This shift is within the one sigma statistical errors on 蟽8 for the DES SV shear catalogue. We further study the potential impact of systematic differences on the critical surface density, 危crit, finding levels of bias safely less than the statistical power of DES SV data. We recommend a final Gaussian prior for the photo-z bias in the mean of n冒z脼 of width 0.05 for each of the three tomographic bins, and show that this is a sufficient bias model for the corresponding cosmology analysis

    Hyperoxemia and excess oxygen use in early acute respiratory distress syndrome : Insights from the LUNG SAFE study

    Publisher Copyright: 漏 2020 The Author(s). Copyright: Copyright 2020 Elsevier B.V., All rights reserved.Background: Concerns exist regarding the prevalence and impact of unnecessary oxygen use in patients with acute respiratory distress syndrome (ARDS). We examined this issue in patients with ARDS enrolled in the Large observational study to UNderstand the Global impact of Severe Acute respiratory FailurE (LUNG SAFE) study. Methods: In this secondary analysis of the LUNG SAFE study, we wished to determine the prevalence and the outcomes associated with hyperoxemia on day 1, sustained hyperoxemia, and excessive oxygen use in patients with early ARDS. Patients who fulfilled criteria of ARDS on day 1 and day 2 of acute hypoxemic respiratory failure were categorized based on the presence of hyperoxemia (PaO2 > 100 mmHg) on day 1, sustained (i.e., present on day 1 and day 2) hyperoxemia, or excessive oxygen use (FIO2 鈮 0.60 during hyperoxemia). Results: Of 2005 patients that met the inclusion criteria, 131 (6.5%) were hypoxemic (PaO2 < 55 mmHg), 607 (30%) had hyperoxemia on day 1, and 250 (12%) had sustained hyperoxemia. Excess FIO2 use occurred in 400 (66%) out of 607 patients with hyperoxemia. Excess FIO2 use decreased from day 1 to day 2 of ARDS, with most hyperoxemic patients on day 2 receiving relatively low FIO2. Multivariate analyses found no independent relationship between day 1 hyperoxemia, sustained hyperoxemia, or excess FIO2 use and adverse clinical outcomes. Mortality was 42% in patients with excess FIO2 use, compared to 39% in a propensity-matched sample of normoxemic (PaO2 55-100 mmHg) patients (P = 0.47). Conclusions: Hyperoxemia and excess oxygen use are both prevalent in early ARDS but are most often non-sustained. No relationship was found between hyperoxemia or excessive oxygen use and patient outcome in this cohort.
