Virtual restoration of the sound of the Hispanic Rite

The virtual acoustic reality techniques are powerful tools for the recovery of acoustical heritage of historic buildings. Through the acoustic modeling and auralization techniques it´s possible to reconstruct the sound of disappeared buildings or the ones with significant modifications over the years, knowing the original geometry and the acoustic characteristics of their surfaces. This paper shows the results of a research project whose goal is the virtual recovery of the sound of the Hispanic Rite, the rite celebrated by Christians of the Iberian Peninsula before the imposition of the Roman Rite in the mid-eleventh century. For this purpose, acoustic models of a series of Pre-Romanesque churches were made. These acoustic models represent the churches in their original state, following the reconstruction hypothesis proposed by leading researchers in medieval liturgical archeology. Multichannel anechoic recordings of several pieces of the music of the Hispanic Rite have been carried out using a spherical array composed of 31 microphones. Finally, static and dynamic auralizations have been developed, involving the different liturgical configurations which were usual in this rite.

Representation of sound localization cues in the auditory thalamus of the barn owl

Barn owls can localize a sound source using either the map of auditory space contained in the optic tectum or the auditory forebrain. The auditory thalamus, nucleus ovoidalis (N.Ov), is situated between these two auditory areas, and its inactivation precludes the use of the auditory forebrain for sound localization. We examined the sources of inputs to the N.Ov as well as their patterns of termination within the nucleus. We also examined the response of single neurons within the N.Ov to tonal stimuli and sound localization cues. Afferents to the N.Ov originated with a diffuse population of neurons located bilaterally within the lateral shell, core, and medial shell subdivisions of the central nucleus of the inferior colliculus. Additional afferent input originated from the ipsilateral ventral nucleus of the lateral lemniscus. No afferent input was provided to the N.Ov from the external nucleus of the inferior colliculus or the optic tectum. The N.Ov was tonotopically organized with high frequencies represented dorsally and low frequencies ventrally. Although neurons in the N.Ov responded to localization cues, there was no apparent topographic mapping of these cues within the nucleus, in contrast to the tectal pathway. However, nearly all possible types of binaural response to sound localization cues were represented. These findings suggest that in the thalamo-telencephalic auditory pathway, sound localization is subserved by a nontopographic representation of auditory space.

The Sound of the Digital Global City

Madrid has been the center of Spanish musical scene and industry since the 80s, when “la movida” becomes the metaphor for the new colorful, young and cosmopolitan country established with the arrival of democracy. The city, in this way, is basically a place. But this sense of place started to crash with the arrival of digital music. In the new paradigm, intermediaries were supposed to disappear and music was something contained in networks and computers. The question now is how to integrate digital music, a nonphysical, individual experience, with the way in which the city of Madrid is lived through in musical terms. With the advent of digital music, concerts became the primary source of income for musicians. The centrality of the gig can be understood as the confirmation that we are living in an economy of experience. This centrality also reorganized the way in which music is produced and consumed: now, records are produced in order to create the opportunity of a musical event (band promote their tour as presentation of their latest recordings) that can be promoted in social networks and media; concerts are the places where musicians construct their fans’ communities and are the places were records are sold, not a way to know the band but to demonstrate both the support for the band and the status of the listeners. To study the place of music in the process of metropolization in Madrid we need to understand music as a field of tension

The Single Supervisory Mechanism: A Sound First Step in Europe’s Banking Union? Egmont European Affairs Paper, March 2013

The financial and economic crisis has hit Europe in its core. While the crisis may not have originated in the European Union, it has laid bare structural weaknesses in the EU’s policy framework. Both public finances and the banking sector have been heavily affected. For a long time, the EU failed to take into account sufficiently the perverse link that existed between the two. Negative evolutions in one field of the crisis often dragged along the other in its downward spiral. In June 2012, in the early hours of a yet another EU Summit, the leaders of the eurozone finally decided to address the link between the banking and sovereign debt crises. Faced with soaring public borrowing costs in Spain and Italy, they decided to allow for the direct European recapitalisation of banks when the Member State itself would no longer be in a position to do so. In exchange, supervision of the banking sector would be lifted to the European level by means of a Single Supervisory Mechanism. The Single Supervisory Mechanism, or SSM in the EU jargon, is a first step in the broader revision of policies towards banks in Europe. The eventual goal is the creation of a Banking Union, which is to carry out effective surveillance and – if needed – crisis management of the banking sector. The SSM is to rely on national supervisors and the ECB, with the ECB having final authority on the matter. The involvement of the latter made it clear that the SSM would be centred on the eurozone – while it is to remain open to other Member States willing to join. Due to the ongoing problems and the link between the creation of the SSM and the recapitalisation of banks, the SSM became one of the key legislative priorities of the EU. In December 2012, Member States reached an agreement on the design of the SSM. After discussions with the European Parliament (which were still ongoing at the time of writing), the process towards making the SSM operational can be initiated. The goal is to have the SSM fully up and running in the first half of 2014. The decisions that were taken in June 2012 are likely to have had a bigger impact than the eurozone’s Heads of State and Government could have realised at the time for two important reasons. On the one hand, creating the SSM necessitates a full Banking Union and therefore shared risk. On the other hand, the decisions improved the ECB’s perception of the willingness of governments to take far-reaching measures. This undoubtedly played a significant role in the creation of the Outright Monetary Transactions programme by the ECB, which has led to a substantial easing of the crisis in the short-term. 1 These short-term gains should now be matched with a stable long-term framework for bank supervision and crisis management. The agreement on the SSM should be the first step in the direction of this goal. This paper provides an analysis of the SSM and its role in the creation of a Banking Union. The paper starts with a reminder of why the EU decided to put in place the SSM (§1) and the state of play of the ongoing negotiations on the SSM (§2). Subsequently, the supervisory responsibilities of the SSM are detailed, including its scope and the division of labour between the national supervisors and the ECB (§3). The internal functioning of the SSM (§4) and its relation to the other supervisors are discussed afterwards (§5). As mentioned earlier, the SSM is part of a wider move towards a Banking Union. Therefore, this paper sheds light on the other building blocks of this ambitious project (§6). The transition towards the Banking Union is important and will prove to be a bumpy ride. Before formulating a number of conclusions, this Working Paper therefore provides an overview of the planned road ahead (§7).

Characteristics of acoustic recordings of narwhals (Monodon monoceros) north of Disko Island, April 2007 and 2009

A total of 1,690 individual narwhal nonecholocation sounds were recorded over 5 h in 2007 and 2009. Each sound was classified as either tonal (FM) or pulsed (amplitude modulated). Omnipresent in all the recordings were the songs of bearded seals, Erignathus barbatus, which were often so loud and numerous that the lower frequency ranges of narwhal sounds could not be distinguished.

Porosity and sound velocity measured in sediment core CIROS-1

The CIROS-1 drillhole, which in 1986 reached a depth of 700 m below the seafloor, is still the only deep hole that can provide information on the velocity structure of the upper crust in McMurdo Sound and the Ross Sea, Antarctica. A careful review and quality control of the downhole logging data of CIROS-1 resulted in a new porosity depth function that is consistent with porosity data from the MSSTS-1 and CRP-1 drillholes. Using existing porosity-velocity equations, it was possible for the first time to obtain reliable velocity information for the upper 700 m of strata off the Victoria Land coast. The calculated synthetic seismograms, based on downhole velocity and density data, fit very well with the existing seismic lines IT90A-71, PD90-12, and NBP9601-89. The quality of the correlation confirms that the average velocity of the top 700 m of strata is about 2 000-2 300 m/s, and not 2 800-3 000 m/s, as was previously assumed. In consequence, these distinctly lower velocities result in shallower depths for the seismic unconformities V3/V4 andV4/V5 and thus may have important implications for further drilling off Cape Roberts.
