Most digital waveguide models of woodwind instruments to date have provided only basic control parameters such as frequency, breath pressure, and vibrato. It is clear that if these models are to gain popularity as real-time performance synthesizers or as composition tools, more flexibility is necessary. This paper discusses the implementation of expressive controls for flutter tonguing, growlin...

In a smart solution-processable luminescent poly(norbornene)/oxazine-1 (Ox1) intercalated fluoromica nanohybrid, the supramolecular organization of the Ox1 dyes can be tuned at the nanoscale level and a deep red emission band switched on by inducing a phase segregation of aligned molecules within the fluoromica layered scaffold. By combining low-temperature photoluminescence and ultrafast pump-...

background: noise is one of the most pervasive hazards in industrial settings. this retrospective study was carried out to assess the effects of noise exposure on hearing status, blood lipids and blood pressure of employees of a local fireclay mine. methods: two hundred and forty male workers were studied. data on audiometric measurements, blood lipids and blood pressure were derived from the w...

With distance learning becoming more of a reality than a novelty in many undergraduate and graduate training programs, web-based clinical simulations can be identified as an instructional option in distance education that has both a sound pedagogical foundation and clinical relevance. The purpose of this article is to report on the instructional effectiveness of a web-based pure-tone audiometry...

UNLABELLED Noise level can be quantified and qualified based on sound characteristics such as intensity, type of spectrum, duration and distribution of the noise exposure during one's working hours. OBJECTIVE To assess noise spectrum and the audiometric configuration of workers. MATERIALS AND METHODS Contemporary cross-sectional cohort carried out in the Federal District - Brazil. We did an...

A retrospective analysis to quantify age-related changes of the incudo-malleolar joint (IMJ) and incudo-stapedial (ISJ), analyse in air-bone gap (ABG) with age, was performed. Defined histologic parameters 153 IMJ 106 ISJ from subjects aged birth 70 years were correlated age. Additionally, audiograms 1760 ears 974 other 20 80 retrospectively analysed ABG The space (age group 0 10 compared 61 ye...

Traditional classroom techniques lacking the advantages offered by multimedia demonstrations often fall short of the goal of furnishing the students with an adequate “ears-on” awareness of the problems of the hearingimpaired. As a first step towards virtual hearing impairment, a CD-ROM with speech material simulating a selection of common types of hearing impairment was produced. The material w...

Noise-induced hearing loss (NIHL) continues to be one of the most prevalent occupational conditions and occurs across a wide spectrum of industries. Occupational hearing loss is preventable through a hierarchy of controls, which prioritize the use of engineering controls over administrative controls and personal protective equipment. The occupational and environmental medicine (OEM) physician w...
