Enhancing the sound absorption of small-scale 3D printed acoustic metamaterials based on Helmholtz resonators

2018

Acoustic metamaterials have recently become of interest for their ability to attenuate sound by breaking the mass-density law. In this paper, acoustic metamaterials based on Helmholtz resonators and capable of attenuating sound up to 30 dB are fabricated for sound absorption applications in the small scale. The proposed metamaterials are subwavelength at a factor of $\lambda /12$ with respect to the lateral dimension of the units. The directional response due to the position of the acoustic source on the sound attenuation provided by the metamaterial is investigated by controlling the location of a loudspeaker with a robot arm. To enhance and broaden the absorption bands, structural modific…

¿Atenuación del compromiso del hablante?: el caso de los evidenciales "por lo visto" y "se ve que"

2018

espanolBuena parte de la bibliografia sobre marcadores evidenciales en espanol senala la atenuacion del compromiso (o responsabilidad) de lo dicho como uno de sus rasgos definitorios. Sin embargo, tanto la nocion de atenuacion como la de compromiso del hablante se han empleado con distintas acepciones, segun los trabajos. En primer lugar, se revisan estas acepciones y se propone, siguiendo a Cornillie/Delbecque, distinguir las nociones compromiso del hablante de implicacion del hablante, las cuales funcionan de manera inversa en algunos usos evidenciales: (i) de las evidencias reportativas a las inferenciales conjeturales hay una escala de menos a mas implicacion del hablante; (ii) en las e…

Single-Sided Deafness: Impact of Cochlear Implantation on Speech Perception in Complex Noise and on Auditory Localization Accuracy.

2017

Objective To assess auditory localization accuracy and speech reception threshold (SRT) in complex noise conditions in adult patients with acquired single-sided deafness, after intervention with a cochlear implant (CI) in the deaf ear. Study design Nonrandomized, open, prospective patient series. Setting Tertiary referral university hospital. Patients Eleven patients with late-onset single-sided deafness (SSD) and normal hearing in the unaffected ear, who received a CI. All patients were experienced CI users. Intervention Unilateral cochlear implantation. Main outcome measures Speech perception was tested in a complex multitalker equivalent noise field consisting of multiple sound sources. …

On the feasibility of personal audio systems over a network of distributed loudspeakers

2018

Los sistemas de reproducción de audio personal se ocupan de la creación de zonas sonoras personales dentro de una habitación sin necesidad de utilizar auriculares. Estos sistemas utilizan un conjunto de altavoces y diseñan los filtros necesarios en cada altavoz con el fin de que la señal de audio deseada llegue a cada persona en la sala lo más libre de interferencias posible. Existen propuestas muy interesantes en la literatura que hacen uso de arrays circulares o lineales, pero en este trabajo estudiamos el problema considerando una red de altavoces distribuidos controlados por un conjunto de nodos acústicos, que pueden intercambiar información a través de una red. Enunciamos el modelo de …

Constancy and evolution of an engaged writing : the work of Carmen de Burgos, journalist, essayist and novelist

2016

Carmen de Burgos died in 1932, leaving behind a considerable amount of written material: thousands of articles published in different newspapers, essays, novels and hundreds of “novelas cortas”. The works and the memory of this women’s rights activist were doomed to oblivion during Franco’s dictatorship. This thesis aims to rediscover and analyse these works from its various perspectives. We have been looking for the constant trends but also the evolutions. Carmen de Burgos has indeed evolved in her conception of the woman’s role and of the rights she had to acquire. In the early stages of her fight, she had been mainly focusing on the acquisition of equalitarian legal and social rights. Sh…

The indexing of persons in news sequences using audio-visual data

2004

We describe a video indexing system that automatically searches for a specific person in a news sequence. The proposed approach combines audio and video confidence values extracted from speaker and face recognition analysis. The system also incorporates a shot selection module that seeks for anchors, where the person on the scene is likely speaking. The system has been extensively tested on several news sequences with very good recognition rates.

Les enjeux cognitifs et linguistiques du sujet parlant plurilingue en néoténie linguistique : le cas du locuteur chypriote-grec

2019

It is not realistic to claim that a speaker can use a language perfectly or that he /she has an excellent knowledge of whichever language, like many speakers like to claim when asked. It is true that a speaker may have some excellent linguistic skills, however cognitively speaking, this doesn’t say much. The cognitive relations that we maintain with the world’s languages are far beyond the linguistic dimension, excessively found in textbooks. Speaking a language means being able to exist in that language, in the sense that our being is there registered. We are led by our linguistic intuition to express ourselves and we do it spontaneously with respect to each language’s boundaries. However,…

Medical Academic Speech. A Corpus-based Investigation of Same-Speaker Most Frequent Content Key Word Repetition in Non-Native English Discourse

2016

Studies on repetition in ELF interactions have been carried out in several domains, but medical academic discourse still remains under-researched. This paper explores same-speaker repetition in a 31,153-word corpus of lectures included in the 100,135-word medical section of the 1 million-word ELFA (English as a Lingua Franca in Academic Settings) corpus. More specifi cally, the corpus was searched for the most frequent same-speaker content key word repetition and corresponding functions, with both immediate and delayed repetition being scrutinized. The results confi rmed the initial hypothesis according to which same-speaker repetition was expected to be pervasive in the data, not only as a…

“I know that the natives must suffer every now and then”: Native / non-native indexing language ideologies in Finnish higher education

2015

This article examines the construction of“native”and“non-native”English use in Finnish higher education. Previous studies on the Finnish situationimplicate not just language ideological but political hierarchies which favour stu-dents from the traditional, hegemonic“Inner circle”countries such as the UnitedKingdom, United States, Australia, Anglophone Canada, Ireland and New Zealand.This hegemonic position of the inner circle variants is being challenged by anemerging normative ELF ideology. Our article tackles the meeting point ofthese ideological positions. We aim to understand how native English speakerideologies might be changing as a result of globalization. We have combineddata from o…
