Hashimoto and Sumita Earth, Planets and Space (2021) 73:143 https://doi.org/10.1186/s40623-021-01472-7 FULL PAPER Open Access Excitation of airwaves by bubble bursting in suspensions : regime transitions and implications for basaltic volcanic eruptions Kana Hashimoto and Ikuro Sumita* Abstract Basaltic magma becomes more viscous, solid-like (elastic), and non-Newtonian (shear-thinning, non-zero yield stress) as its crystal content increases. However, the rheological efects on bubble bursting and airwave excitation are poorly understood. Here we conduct laboratory experiments to investigate these efects by injecting a bubble of volume V into a refractive index-matched suspension consisting of non-Brownian particles (volumetric fraction φ ) and a Newtonian liquid. We show that depending on φ and V, airwaves with diverse waveforms are excited, covering a frequency band of f = O(10 − 104) Hz. In a suspension of φ ≤ 0.3 or in a suspension of φ = 0.4 with a V smaller than critical, the bubble bursts after it forms a hemispherical cap at the surface and excites a high-frequency (HF) wave (f ∼ 1 − 2 × 104 Hz) with an irregular waveform, which likely originates from flm vibration. However, in a suspension of φ = 0.4 and with a V larger than critical, the bubble bursts as soon as it protrudes above the surface, and its aper- ture opens slowly, exciting Helmholtz resonance with f = O(103) Hz. Superimposed on the waveform are an HF wave component excited upon bursting and a low-frequency (f = O(10) Hz) air fow vented from the defating bubble, which becomes dominant at a large V. -
Questions: Helmholtz Resonance
Questions: Helmholtz resonance 1 Helmholtz resonance may occur when an enclosed volume of air is connected to the atmosphere by a short exit pipe when simple harmonic oscillations of air in the pipe are driven by pressure changes in the enclosed volume. The frequency of the resonance is given by … 1/2 f = v/2[Ax/VL] … where v is the velocity of sound in air, V is the volume of air enclosed air, Ax is the cross sectional area and L is the effective length of the pipe. a Explain, in physical terms, why the effective length L in the frequency relationship is a little longer than the actual length of the exit pipe. b Explain, in physical terms, why halving the volume of the enclosed air raises the resonant frequency. c A Helmholtz resonator is completely filled with carbon dioxide. Will the resonant frequency change and if so by how much? 2 A empty coffee container is shown. The round hole in the cap has a diameter of 1.45 cm. Short lengths of plastic pipe with an internal radius of 0.65 cm convert the container into a Helmholtz resonator. Measured resonant frequencies are plotted below against frequencies 1/2 calculated with the Helmholtz relationship f = v/2[Ax/VL] for four pipe lengths. a Are calculations less satisfactory for shorter or longer pipe lengths? b Increasing the effective length of the pipe by 1.3 cm, recalculating and plotting the revised data gives the graph below. c Which additional point on the graph represents the resonance when the pipe length is zero? d The sound box on a guitar is said to behave as Helmholtz resonator with an effective pipe length. -

Electric & Acoustic Guitar Strings: a Recording of Harmonic Content
Electric & Acoustic Guitar Strings: A Recording of Harmonic Content Ryan Lee, Graduate Researcher Electrical & Computer Engineering Department University of Illinois at Urbana-Champaign In conjunction with Professor Steve Errede and the Department of Physics Friday, January 10, 2003 2 Introduction The purpose of this study was to analyze the harmonic content and decay of different guitar strings. Testing was done in two parts: 80 electric guitar strings and 145 acoustic guitar strings. The goal was to obtain data for as many different brands, types, and gauges of strings as possible. Testing Each string was tested only once, in brand new condition (unless otherwise noted). Once tuned properly, each string was plucked with a bare thumb in two different positions. For the electric guitar, the two positions were at the top of the bridge pickup and at the top of the neck pickup. For the acoustic guitar, the two positions were at the bottom of the sound hole and at the top of the sound hole. The signal path for the recording of an electric guitar string was as follows: 1994 Gibson SG Standard to ¼” input on a Mark of the Unicorn (MOTU) 896 to a computer (via firewire). Steinberg’s Cubase VST 5.0 was the software used to capture the .wav files. The 1999 Taylor 410CE acoustic guitar was recorded in an anechoic chamber. A Bruel & Kjær 4145 condenser microphone was connected directly to a Sony TCD-D8 portable DAT recorder (via its B&K preamp, power supply, and cables). Recording format was mono, 48 kHz, and 16- bit. -
Geomungo Factory
★★★★★ PAMS CHOICE in Korea 2010 WOMEX Official Showcase in Greece 2012 ROSKILDE FESTIVAL in Denmark 2013 WORLD MUSIC ENSEMBLE GEOMUNGO FACTORY PHOTO BY EUNYOUNG KIM Five-star rating ★★★★★ LONDON EVENING STANDARD “Whatever you call it, it is original, powerful and thrilling. And certainly like nothing you have ever heard before.” Simon Broughton Top of world music magazine <SONGLINES> 3 GEOMUNGO FACTORY What makes Korea so special is the way it respects its distinctive past, while staying at the cutting edge of technology and innovation – and if there’s one group that sums that up in music, it’s Geomungo Factory (which is pronounced Ko-mungo Factory). The geomungo zither is over a thousand years old and you won’t fine an instrument like it anywhere else in the world. It has six silk strings and is played by hitting and pluking them with a short stick, giving it a deep, muscular sound, both rhythmic and melodic. Geomungo Factory have also created new instrument – the ‘Xylophone geomungo’, ‘the cello geomungo’ and the ‘electric geomungo’ with a wah-wah pedal. Like Konono No. 1 from Congo and Hanggai from Mongolia, Geomungo Factory sound ancient and contemporary at the same time. Geomungo Facoty includes three geomungo players, Yoo Mi-young, Jung Ein-ryoung and Lee Jung-seok, who are all traditional players, plus Kim Sun-a, who plays gayageum, the plucked zither with 18 or more strings, which is more commomly heard in Korea than the geomungo. “Most people think traditional music is boring,“ they say, “so we want to make geomungo music that -

Pedal in Liszt's Piano Music!
! Abstract! The purpose of this study is to discuss the problems that occur when some of Franz Liszt’s original pedal markings are realized on the modern piano. Both the construction and sound of the piano have developed since Liszt’s time. Some of Liszt’s curious long pedal indications produce an interesting sound effect on instruments built in his time. When these pedal markings are realized on modern pianos the sound is not as clear as on a Liszt-time piano and in some cases it is difficult to recognize all the tones in a passage that includes these pedal markings. The precondition of this study is the respectful following of the pedal indications as scored by the composer. Therefore, the study tries to find means of interpretation (excluding the more frequent change of the pedal), which would help to achieve a clearer sound with the !effects of the long pedal on a modern piano.! This study considers the factors that create the difference between the sound quality of Liszt-time and modern instruments. Single tones in different registers have been recorded on both pianos for that purpose. The sound signals from the two pianos have been presented in graphic form and an attempt has been made to pinpoint the dissimilarities. In addition, some examples of the long pedal desired by Liszt have been recorded and the sound signals of these examples have been analyzed. The study also deals with certain aspects of the impact of texture and register on the clarity of sound in the case of the long pedal. -
Chapter IX: Ukrainian Musical Folklore Discography As a Preserving Factor
Art Spiritual Dimensions of Ukrainian Diaspora: Collective Scientific Monograph DOI 10.36074/art-sdoud.2020.chapter-9 Nataliia Fedorniak UKRAINIAN MUSICAL FOLKLORE DISCOGRAPHY AS A PRESERVING FACTOR IN UKRAINIAN DIASPORA NATIONAL SPIRITUAL EXPERIENCE ABSTRACT: The presented material studies one of the important forms of transmission of the musical folklore tradition of Ukrainians in the United States and Canada during the XX – the beginning of the XXI centuries – sound recording, which is a component of the national spiritual experience of emigrants. Founded in the 1920s, the recording industry has been actively developed and has become a form of preservation and promotion of the traditional musical culture of Ukrainians in North America. Sound recordings created an opportunity to determine the features of its main genres, the evolution of forms, that are typical for each historical period of Ukrainians’ sedimentation on the American continent, as well as to understand the specifics of the repertoire, instruments and styles of performance. Leading record companies in the United States have recorded authentic Ukrainian folklore reconstructed on their territory by rural musicians and choirs. Arranged folklore material is represented by choral and bandura recordings, to which are added a large number of records, cassettes, CDs of vocal-instrumental pop groups and soloists, where significantly and stylistically diversely recorded secondary Ukrainian folklore (folklorism). INTRODUCTION. The social and political situation in Ukraine (starting from the XIX century) caused four emigration waves of Ukrainians and led to the emergence of a new cultural phenomenon – the art and folklore of Ukrainian emigration, i.e. diaspora culture. Having found themselves in difficult ambiguous conditions, where there was no favorable living environment, Ukrainian musical folklore began to lose its original identity and underwent assimilation processes. -

(Tech.) Henri Penttinen In this thesis, the vibrational modes and radiation of the body of a 15-string instrument called the kantele are modelled using the finite element method. Two traditional body structures, the top-plate kantele and the box kantele, are compared to a modified kantele with an air gap separating the top and the back plate. The modified structure allows the kantele top plate to vibrate freely. In addition, together the top and back plate create an enclosed air mass that has its own vibrational modes. The modified kantele has previously been shown to be louder than the traditional top plate kantele. In this thesis, it is shown that the modified kantele includes vibrational modes of both the freely vibrating top plate and the enclosed air. Thus, it has a higher mode density than the traditional kanteles. Because of the coupling of the enclosed air modes to the body, the modified kantele radiates more omni-directionally than the traditional kanteles. -

Model-based digital pianos: from physics to sound synthesis Bal´azsBank, Member, IEEE and Juliette Chabassier∗yz October 12, 2018 Abstract Piano is arguably one of the most important instruments in Western music due to its complexity and versatility. The size, weight, and price of grand pianos, and the relatively simple control surface (keyboard) have lead to the development of digital counterparts aiming to mimic the sound of the acoustic piano as closely as possible. While most commercial digital pianos are based on sample playback, it is also possible to reproduce the sound of the piano by modeling the physics of the instrument. The pro- cess of physical modeling starts with first understanding the physical principles, then creating accurate numerical models, and finally finding numerically optimized signal processing models that allow sound synthesis in real time by neglecting inaudible phe- nomena, and adding some perceptually important features by signal processing tricks.
