Can a natural singing voice be enhanced through digital processing? Implications of voice training and vocology in singers

Introduction. The traditional way of facilitating a good singing voice has been achieved through rigorous voice training. In the modern days, however, there are some aspects of the singing voice that can be enhanced through digital processing. Although in the past, the frequency or intensity manipulations had to be achieved through the various singing techniques of the singer, technology today allows the singing voice to be enhanced from the instruments within recording studios. In essence, the traditional voice pedagogy and the evolution of digital audio processing both strive to achieve a better quality of the singing voice, but with different methods. Nevertheless, the major aspects of how the singing voice can be manipulated are not communicated among the professionals in each field. Objective. This paper offers insights as to how the quality of the singing voice can be changed physiologically through the traditional ways of voice training, and also digitally through various instruments that are now available in recording studios. Reflection. The ways in which singers train their voice must be mediated with the audio technology that is available today. Although there are aspects in which the digital technology can aid the singer’s voice, there remain areas in which the singers must train their singing system in a physiological level to produce a better singing voice.

Digital audio technology in music teaching and learning: A preliminary investigation

The inclusion of digital audio technology for sampling, editing, mixing and producing music in formal music classrooms has been considered a needed area of expansion across the music teaching and learning landscape. Current research suggests that music technology, defined broadly, is often disregarded in many music classrooms. However, the ubiquity of music technology suggests its relevancy in the digital age, especially for sampling editing, mixing and producing music. The purpose of this research was to survey the current climate of music education across all levels of instruction, with a special focus on teaching digital audio technology using MIDI controllers and audio production techniques. A researcher-developed survey was distributed to a population of music teachers across the United States (N=83). Results found that participants taught few digital audio technology concepts, used Garageband extensively, were self-taught, relied on out-of-date hardware and used a variety of MIDI controllers. Implications for music education and considerations for additional research are provided in conclusion.

Podcasts as emerging tool for medical education: a critical perspective

Background: Podcasts have started knocking the educational doors after setting their feet strong in entertainment grounds. There has always been a trend to welcome and introduce new ideas and innovative ways in medical education for the benefit of students. No doubts, they are an emerging tool for education. The study aims to know and evaluate critically the students’ perspective about the novel aural technology and its relevance to be included in the curriculum.Methods: A sample size of 110 undergraduate medical students enrolled in two private post graduate coaching centres in metropolitan regions of Delhi was taken to conduct the study. A semi structured pen and paper questionnaire was created and made to be filled by the participants.Results: Aware students actively participated in the survey and shared their preferences and opinions, but many lacked knowledge and interest in the newly introduced and conveyed audio technology. This was a direct result of their surroundings, friends and family circle. Generally, there was a welcome response towards podcasts being in trend and to be included as a supplementary teaching tool along with present ongoing modes of education.Conclusions: Students’ opinion taken over from time to time is of great value to introduce modern educational reforms. Podcasts are a very effective add-on tool if introduced in medical education. There still exists a wide room for research and evidence-based use of this technology and much work needs to be done to actually add a new brick in the current structure of medical education.

Spectral Design in Music

This chapter traces the emergence of the spectrum as structural concern in music composition, performance and production. The earliest signs of such developments are traced to the beginning of the 20th century, in the musical revolutions of that era. This is followed by the developments in audio technology, which brought to the fore the spectral qualities of sound. Post-war electronic music and computer music are shown to have played a decisive part in the conquering of the spectrum by composers. The latter part of the chapter discusses two case studies of spectral music writing.

The Application of Binaural System on Virtual Reality Technology Through the Animation of Wayang Kulit Yogyakarta Performance

Binaural system is an audio technology which relatively easy to apply these days. This was due to the growth in technology developments of the audio recording system. The application of this system is not well known in Indonesia. This was aligned with public assumption where Wayang Kulit performance are one of many unappreciated forms of arts in Indonesia. The main problem that occurred is that whether the binaural system conjoined with the Virtual Reality (VR) System can make the public more appreciate the art form of Indonesian Wayang Kulit. By using the theory of perception conjoin with the binaural technology, it can be assumed that the audience can have a new experience from the performance through the VR thus elevating their appreciation for the art itself. This research will be divided into three stages. The first stage focused on the application of the binaural system on Wayang Kulit Animation through VR system. The second stage will focus on the product assessment whether it can elevate the appreciation of the audience for the art itself. The third stage will focus on applying the binaural system on other Indonesian art form. This year, the research will begin at the first stage.

PASSENGER CAR SPEED ASSESSMENT RELATIONSHIP TO THE NOISE CAUSED

<p>Noise is defined as a human unwanted sound. The main sources of noise on toll roads are heavy vehicles and light vehicles. Noise pollution is often interpreted as unwanted sound or wrong sound at the wrong time. as heavy industry grows, traffic crowds, transportation facilities, and excessive use of audio technology. In addition there is generally noise strongly related to annoyance. Noise is everywhere and disturbance is one of the most common reactions to noise.. Speed is the size of a vector that shows how fast objects move. This research aims to find out the level of traffic noise and its distribution in front of SDN Cimahpar 01. The research method uses multiple linear analysis with the SPSS program by entering traffic data, vehicle speed and noise generated. The results were obtained that in SDN Cimahpar 01 area with the highest linear regression value between speed and noise that arises is 98% with linear regression equation y=52,390+0.298x1+0.229x2+0.245x3+0.205x4. Based on the similarity, the noise level value generated by the speed of the vehicle is 52.39 dBA with the provision of no increase or decrease in vehicle speed, this noise level is very strong because above the raw value of the activity noise level set by the Decree of the Minister of Environment No. 48 of 1996 which is 80 dBA.</p>

The Effectiveness of Binaural Beat Audio on Anxiety State In Patients Undergoing Fiberoptic Bronchoscopy: A Prospective Randomised Controlled Trial

Background: Fiberoptic bronchoscopy is an invasive procedure known to contribute anxiety in patients. Binaural beat, an audio technology with different frequency between ears to entrain the brainwaves, has been used to reduce anxiety in some operations. This study aimed to determine the anxiolytic effects of binaural beat in patients undergoing fiberoptic bronchoscopy. Methods: All eligible subjects were randomly assigned to receive binaural beat music, plain music, or no music. They were asked to wear earphones approximately 15 minutes before, during, and after the bronchoscopy. The level of anxiety was measured with State-Trait Anxiety Inventory (STAI) questionnaires. Blood pressure, heart rate, and sedative drug use were also recorded.Results: One hundred and twelve subjects were included and randomised into 3 groups, including binaural beat music (n=38), plain music (n=38), and no music (n=36). Baseline characteristics were non-significantly different between the groups. The mean change of post-bronchoscopy STAI state scores in binaural beat music, plain music, and no music groups was -7.26 (p<0.001), -3.92 (p=0.005), and -1.12 (p=0.454), respectively. The mean systolic blood pressure and diastolic blood pressure were significantly decreased from baseline for -9.89 (p=0.002) and -5.76 (p=0.005), respectively in binaural group. The mean heart rate were increased from baseline for 3.32 (p=0.035), 5.21 (p=0.038), and 3.64 (p=0.149) in binaural beat music, plain music, and no music groups, respectively.Conclusions: The binaural beat music was proven to reduce anxiety among patients undergoing fiberoptic bronchoscopy.Trial registration: TCTR, TCTR20200915002.
