Abstract:
Objective.To compare hearing and speech understanding between a new, nonskin penetrating Baha system (Baha Attract) to the current Baha system using a skin-penetrating abutment.Methods.Hearing and speech understanding were measured in 16 experienced Baha users. The transmission path via the abutment was compared to a simulated Baha Attract transmission path by attaching the implantable magnet to the abutment and then by adding a sample of artificial skin and the external parts of the Baha Attract system. Four different measurements were performed: bone conduction thresholds directly through the sound processor (BC Direct), aided sound field thresholds, aided speech understanding in quiet, and aided speech understanding in noise.Results.The simulated Baha Attract transmission path introduced an attenuation starting from approximately 5 dB at 1000 Hz, increasing to 20–25 dB above 6000 Hz. However, aided sound field threshold shows smaller differences and aided speech understanding in quiet and in noise does not differ significantly between the two transmission paths.Conclusion.The Baha Attract system transmission path introduces predominately high frequency attenuation. This attenuation can be partially compensated by adequate fitting of the speech processor. No significant decrease in speech understanding in either quiet or in noise was found.

Abstract:
Conventional hearing protection devices have often been implicated in compromised auditory perception, degraded signal detection, and reduced speech communication abilities. Recent technological developments have been used to augment hearing protectors in an attempt to alleviate these problems for the user, while at the same time providing adequate attenuation. Operational characteristics, design features, performance data, and applications for active noise reduction, sound transmission, frequency-selective, adjustable attenuation, amplitude-sensitive, and uniform attenuation devices are discussed.

Abstract:
ISO 3382-3 is globally used to determine the room acoustic conditions of open-plan offices using in situ measurements. The key outcomes of the standard are three single-number quantities: distraction distance, rD, A-weighted sound pressure level of speech, Lp,A,S,4m, and spatial decay rate of speech, D2,S. Quantities Lp,A,S,4m and D2,S describe the attenuation properties of the office due to room and furniture absorption and geometry. Our purpose is to introduce a new single-number quantity, comfort distance rC, which integrates the quantities Lp,A,S,4m and D2,S. It describes the distance from an omnidirectional loudspeaker where the A-weighted sound pressure level of normal speech falls below 45 dB. The study explains why the comfort criterion level is set to 45 dB, explores the comfort distances in 185 offices reported in previous studies. Based on published data, the rC values lie typically within 3 m (strong attenuation) and 30 m (weak attenuation). Based on this data, a classification scheme was proposed. The new quantity could benefit the revised version of ISO 3382-3.

Abstract:
To effectively implement an occupational hearing conservation program, employers must know the amount of attenuation (noise reduction) provided by the hearing protective devices used by their employees. Currently standardized test methods, performed under laboratory conditions, cannot be easily implemented in industrial settings, and previously proposed field methods have depended upon the use of special headphones which are not typically available in the workplace. These problems have led many occupational hearing conservationists to use standard audiometric headphones to evaluate the attenuation provided to employees using insert-type hearing-protective devices. There has, however, been little research into the validity of using standard audiometric headphones to determine attenuation values. The purpose of this study was to describe a procedure for determining the attenuation of insert-type hearing-protective devices using standard audiometric earphones, typical industrial audiometric equipment, and other easily obtainable materials.

Abstract:
Speech intelligibility tests using three headset systems, two passive and one with active noise reduction technology, were conducted. Nine listeners, six males and three females, responded to 180 50-word Modified Rhyme Word Lists presented under two noise conditions, two conditions of bilateral phase reversal of the speech signal, and the three headset systems. These three independent variables were studied in a full factorial within-subjects design. The noise conditions were pink noise and recordings from the troop carrying compartment of a u.S. Army M-2 Bradley Fighting Vehicle (tank noise having substantial low frequency energy). Phase reversal of the speech signal was also tested for its effect on speech intelligibility. The three headset systems were the David Clark Noise Attenuating Aviation Headset, and the Bose Aviation Headset used in both its passive and active mode. Active noise reduction technology employs the physical principle of constructive and destructive interference by creating signals which are identical to the noise under the earmuff but out of phase by 180 degrees. This technology is most effective at frequencies below 1000 Hz. Results showed that the Bose headset in its active mode required a significantly higher speech-to-noise ratio in both noise environments than the two passive headset systems to achieve the 70% level of speech intelligibility, the dependent variable in this study. The mean speech level under the Bose headset in its active mode was 2.8 dB higher in tank noise and 3.5 dB higher in pink noise than under the David Clark headset. The Bose headset in the active mode, however, provided a greater degree of broadband attenuation especially in the lower frequency range, e.g. < 630 Hz. Phase reversal proved to be of no benefit to performance in either noise environment. The pink noise proved to be the harsher environment for speech intelligibility than did the tank noise, primarily due to the increased levels in the speech bandwidth. Articulation Index scores for the three headset systems evidenced that the differences in performance among the three headset systems were in part the result of better earphone response characteristics in the principal speech bandwidth (600 - 4000 Hz) in conjunction with the strong attenuation performance of the David Clark headset in that same range. It is suggested that, in the absence of better earphone response characteristics and a broader bandwidth of active noise reduction performance, speech intelligibility is no better under active noise reduction headsets than under quality passive headsets. Further, the levels of speech intelligibility attained by active noise reduction headsets are at a cost of increased signal strength and higher purchase price.

Abstract:
The need for hearing protection in industry has evolved from the growing awareness of the detrimental effects of noise on hearing and recent legislation enacted to protect the hearing of noise-exposed employees through the use of hearing conservation programs. In lieu of expensive or impractical engineering and administrative controls, personal hearing protection devices (HPDs) are considered to be the most practical and effective means of protecting employees from the damaging effects of noise in industry today.

Abstract:
This work investigates the application of active noise control (ANC) to speech. ANC has had success reducing tonal noise. In this work, that success was extended to noise that is not completely tonal but has some tonal elements such as speech. Limitations such as causality were established on the active control of human speech. An optimal configuration for control actuators was developed for a sphere using a genetic algorithm. The optimal error sensor location was found from exploring the nulls associated with the magnitude of the radiated pressure with reference to the primary pressure field. Both numerically predicted and experimentally validated results for the attenuation of single frequency tones were shown. The differences between the numerically predicted results for attenuation with a sphere present in the pressure field and monopoles in the free-field are also discussed.The attenuation from ANC of both monotone and natural speech is shown and a discussion about the effect of causality on the results is given. The sentence “Joe took father’s shoe bench out” was used for both monotone and natural speech. Over this entire monotone speech sentence, the average attenuation was 8.6 dB with a peak attenuation of 10.6 dB for the syllable “Joe”. Natural speech attenuation was 1.1 dB for the sentence average with a peak attenuation on the syllable “bench” of 2.4 dB. In addition to the lower attenuation values for natural speech, the pressure level for the word “took” was increased by 2.3 dB. Also, the harmonic at 420 Hz in the word “father’s” of monotone speech was reduced globally up to 20 dB. Based on the results of the attenuation of monotone and natural speech, it was concluded that a reasonable amount of attenuation could be achieved on natural speech if its correlation could approach that of monotone speech.

[ES] Esta investigación tiene como objeto de estudio los mecanismos de atenuación empleados en la lengua oral china para contribuir con los estudios de lingüística conversacional china en un aspecto carente de estudios previos. Los objetivos principales del presente estudio son: 1) describir las características de los mecanismos de atenuación en chino. y 2) clasificar los mecanismos de atenuación que se utilizan en la lengua china oral. De ahí se desprenden cuatro objetivos específicos: 1) analizar de qué forma influye el contexto situacional y la cultura en el uso de las estrategias de atenuación en chino; 2) examinar las funciones de los mecanismos de atenuación; 3) explicar las características de los mecanismos de atenuación en los tipos de actos de habla y 4) identificar las características principales de los atenuantes en función de las variables género, edad y formación académica. Para cumplir con los objetivos planteados se ha elaborado un corpus formado por 14 conversaciones coloquiales que suman un total de 10 horas y 27 minutos de duración. Las relaciones que hay entre los interlocutores son de amistad y parentesco. La identificación de los mecanismos utilizados se realiza en base a la ficha metodológica de Albelda et al. (2014) A partir del análisis del corpus se han obtenido 21 tipos de mecanismos, cuyas características de uso evidencian el impacto cultural en ellas. Así mismo, se ha mostrado que la función por la que más se atenúa es la de prevención de amenazas a la imagen y, por la que menos, por la de reparación. Con respecto a los tipos de actos de habla, el asertivo es el que presenta un mayor número de uso de mecanismos de atenuación. Por último se ha mostrado que existen diferencias en el uso de los mecanismos de atenuación según las variables de género, edad y nivel de formación académica.
[CA] Aquesta tesi tracta d'investigar els mecanismes d'atenuació emprats en la llengua oral xinesa. Amb aquesta investigació es pretén contribuir en un camp que no té estudis d'aquests mecanismes en converses en llengua xinesa. Els objectius principals d'aquest estudi són: en primer lloc, classificar els mecanismes d'atenuació que s'utilitzen en la llengua xinesa oral, i en segon lloc, descriure les característiques d'aquests mecanismes d'atenuació. Es desprenen quatre objectius específics, que són: 1) analitzar si el context i la cultura influeixen en l'ús de les estratègies d'atenuació en xinès; 2) examinar les funcions dels mecanismes d'atenuació i la relació entre ells; 3) explicar les característiques dels mecanismes d'atenuació en els tipus d'actes de parla; i 4) identificar les característiques més freqüents lligades a les variables de gènere, edat i formació acadèmica. Per complir amb els objectius plantejats es va elaborar un corpus propi format per 14 converses col·loquials amb un total de 10 hores i 27 minuts de durada. Les relacions que hi ha entre els interlocutors són d'amistat o familiars. La identificació dels mecanismes utilitzats es realitza basant-se en la fitxa metodològica d'Albelda et al. (2014) A partir d'l'anàlisi s'han obtingut 21 tipus de mecanismes d'atenuació utilitzats en el corpus, les característiques de l'ús dels mecanismes van evidenciar l'impacte cultural en elles. així mateix, s'ha mostrat que la funció per la que més s'atenuen és la funció de prevenció d'amenaces a la imatge, i la que menys és la funció de reparació. Pel que fa als tipus d'acte de parla, en l'acte assertiu es presenta un major nombre de casos de mecanismes d'atenuació. Finalment s'ha mostrat que hi ha diferències en l'ús dels mecanismes d'atenuació segons el gènere, edat i nivell d'estudis.
[EN] This research addresses the issue of the usage of attenuation mechanism in oral Chinese. With this research we intend to contribute to fill in the gap of such studies in Chinese. The main objective of this research is to classify the attenuation mechanism used in oral Chinese language and to describe their characteristics. Four specific objectives include: 1) to analyze if the context and the culture influence the use of attenuation mechanism in Chinese; 2) to examine the functions of attenuation mechanism and the relationship between them; 3) to explain the characteristics of the attenuation mechanism in different types of speech act; and 4) to identify the significant differences between variables such as gender, age and educational level. In order to meet the objectives, we elaborated a corpus of 14 colloquial conversations with 10 hours and 27 minutes of audio recording. The relationships between the interlocutors are friends or family. The identification of the mechanisms used is carried out based on the methodological study of Albelda et al. (2014) 21 types of attenuation mechanism used in the corpus were obtained, the characteristics of the use of the mechanisms showed evidence of the cultural impact on them. Moreover, it revealed that the function of which is the most attenuated, is the function of preventing threats to the interlocutor's face, and the one that is least attenuated is the function of repair the damage caused by the face threating act. In all the types of speech act attenuated we found that in the assertive act there are a greater number of cases by using attenuation mechanism. At last, it has been shown that there are differences in the usage of attenuation mechanism according to gender, age and educational level.

Abstract:
Attenuation and scatter are limiting factors in image quality and quantitation of organ function by single photon emission computed tomography (SPECT). To correct brain images for attenuation an effective water/tissue attenuation coefficient of 0.12 cm$ sp{-1}$ (at 140 keV) or larger has been recommended in order to compensate for the additional bone (skull) attenuation.
It has been determined that the reconstructed images are overcorrected in the centre by 5%, and the optimum correction occurs for a reduced coefficient of 0.09 cm$ sp{-1}$. The overcorrection is due to increased attenuation at the edges of all projections where the path length through the bone is greater, although the bone also increases the scatter at the projection edges.
A correction scheme which uses effective bone and water coefficients was developed to compensate for the attenuation. Alternatively, prior to attenuation correction, a common scatter correction was found to be effective in explicitly removing the bone and water scatter.

Full text
Abstract:
Attenuation correction minimizes the impact of body habitus on the acquired myocardial count distribution. The superior diagnostic performance of corrected over uncorrected SPECT images is due to improved specificity and normalcy rate. The transmission image used for attenuation correction is obtained using CT or Gd-153 line sources. Artifactual defects may develop with attenuation correction if the transmission image is truncated, of poor count density, significantly contaminated by downscatter or misregistered with the emission image. Attenuation correction can help decrease the radiation exposure to the patient and improve the workflow in the nuclear laboratory by obviating the need for rest imaging on stress-first myocardial perfusion SPECT protocols. Coronary calcium on the CT attenuation image can add diagnostic and prognostic value to normal myocardial perfusion SPECT in patients without known coronary artery disease. Incidental noncardiac findings of potential clinical relevance are frequently found on the CT attenuation image and should be described on the clinical report.

Abstract:
Single photon emission computed tomography (SPECT) allows an organ to be imaged in three dimensions with enhanced contrast. Of particular relevance in nuclear cardiology, it also allows the heart to be reorientated relative to its own axes, and slices presented in standard orthogonal planes. Scintigraphic imaging is thereby rendered more accessible to cardiologists already familiar with echocardiography and other imaging modalities. This chapter explores specific issues of instrumentation, acquisition, and processing, discussing camera options and specific quality control issues. SPECT reconstruction is covered with reference to both filtered back-projection and iterative reconstruction. Other key aspects of SPECT covered include image reorientation, colour display, gated SPECT, and attenuation correction.

Abstract:
Nuclear cardiology is generally considered a clinical phenomenon of the past four decades. However, the field has its roots in earlier times. This chapter focuses on these historical roots as they have evolved into the present era. The initial application of radioisotopes to cardiac studies occurred in the mid-1920s. Ventricular function was evaluated in the 1960s and 1970s by first pass and equilibrium techniques. Myocardial stress perfusion imaging was first performed using potassium-43 and exercise in 1973. Stress imaging rapidly evolved thereafter with new tracers (thallium-201 and technetium-labeled agents) and from planar to SPECT approaches. Perfusion imaging rapidly proved its value diagnostically and in assessing prognosis. Infarct imaging reached its peak use in the 1970s but is now no longer employed. Advances in hybrid imaging, combining CT with radionuclide imaging has recently allowed attenuation correction as well as providing the combination of anatomic and physiologic data. PET myocardial perfusion studies have recently become a standard approach for evaluating perfusion, absolute coronary blood flow and coronary reserve. PET FDG studies of cardiac sarcoidosis have recently been established as a new approach for defining myocardial inflammation. New SPECT systems provide high sensitivity, high resolution studies, allowing for radiation dose reduction and high quality imaging studies.

Abstract:
Cardiac PET enables evaluation of multiple aspects of myocardial perfusion, metabolism, cell signaling and function that are of value both for diagnosis and prognostication in patients with known or suspected CAD and its use has increased in the past three decades. PET myocardial perfusion imaging (MPI) offers several technological advantages over SPECT including; higher photon energy, higher count sensitivity, more consistent attenuation correction and the ability to measure myocardial blood flow in absolute terms. These result in faster imaging times, lower patient radiation exposure and increased diagnostic accuracy. However the availability of PET MPI remains limited, predominantly due to expense. Efforts are underway to expand the use of PET MPI beyond larger centers, with lower-cost scanners and more widely available radiotracers. In this chapter we describe the latest advances in PET camera technology and image reconstruction as well as potential image artifacts specific to PET MPI. We go on to discuss diagnostic accuracy and prognostic value of PET MPI as well as its role in clinical practice.
