Frequencies of Inaudible High-Frequency Sounds Differentially Affect Brain Activity: Positive and Negative Hypersonic Effects. Abstract The hypersonic effect is a phenomenon in which sounds containing significant quantities of non-stationary high-frequency components (HFCs) above the human audible range (max. 20 kHz) activate the midbrain and diencephalon and evoke various physiological, psychological and behavioral responses.
Yet important issues remain unverified, especially the relationship existing between the frequency of HFCs and the emergence of the hypersonic effect. In this study, to investigate the relationship between the hypersonic effect and HFC frequencies, we divided an HFC (above 16 kHz) of recorded gamelan music into 12 band components and applied them to subjects along with an audible component (below 16 kHz) to observe changes in the alpha2 frequency component (10–13 Hz) of spontaneous EEGs measured from centro-parieto-occipital regions (Alpha-2 EEG), which we previously reported as an index of the hypersonic effect.

Hypersonic effect - Wikipedia. The hypersonic effect is a term coined to describe a phenomenon reported in a controversial scientific study by Tsutomu Oohashi et al., which claims that, although humans cannot consciously hear ultrasound (sounds at frequencies above approximately 20 kHz), the presence or absence of those frequencies has a measurable effect on their physiological and psychological reactions. Numerous other studies have contradicted the portion of the results relating to the subjective reaction to high-frequency audio, finding that people who have "good ears"[dead link] listening to Super Audio CDs and high resolution DVD-Audio recordings on high fidelity systems capable of reproducing sounds up to 30 kHz cannot tell the difference between high resolution audio and the normal CD sampling rate of 44.1 kHz. Favoring evidence Contrary evidence There are contradictions in Oohashi's results. Counter-contrary evidence See also References
The 432Hz 'God' Note: Why Fringe Audiophiles Want to Topple Standard Tuning. The first time Ivan Yanakiev heard an instrument tuned to 432 Hertz, he says, it was like he’d heard God speak. In the men’s dressing room at the Musical Drama Theatre Konstantin Kisimov in Veliko Tarnovo, Bulgaria, Yanakiev, a young, National Academy-schooled conductor, had his friend, Velimir, tune his cello down eight Hz from the standard A=440Hz. They were arranging an experiment. Velimir, “a skilled cellist,” Yanakiev told me, started in on the prelude to Bach’s “Cello Suite No. 1 in G major.”
“So, la, si, so, si so, si, so/ So, la, si, so, si, so, si, so,” Yanakiev sings to illustrate. It’s one of the most often performed and well known pieces by Bach, but in that backroom rendition, transposed not even a half of a piano key lower, the song sounded fresh and exciting. “It was a channelling of pure light and love that vibrated through the whole room,” he said. In November 2013, along with Alexandros Geralis, Yanakiev cofounded the 432 Orchestra. Pitch comparison: 432 Hz vs. 440 Hz.
Creative Strategies w/ Matt Shadetek: Imperfectionism. In his latest article on creative strategies for artists, Dubspot Logic instructor and course designer Matt Shadetek breaks down the Japanese concept of wabi-sabi and the value of imperfection in art. People sometimes ask me if their work comes across as “professional.” For beginners, this is very important. Beginners have the desire to make something that gives the impression that they know what they’re doing, that they’re in control of the process. Often we feel that in order to look competent, powerful and in control, we need to make everything look easy, smoothing off every rough edge and polishing everything until it looks perfect.
A while back I read a piece by Seth Godin on his excellent blog. “Sometimes, ‘never let them see you sweat,’ is truly bad advice. This is really useful advice for us music makers for two reasons: 1) It might allow us to be a little less hard on ourselves as we strive to create high quality work. We are not robots or one-person art factories. Logic. Visible Cloaks: Synthesis and Systems. According to the dictionary, synthesis is the combining of constituent elements of separate material or abstract entities into a single or unified entity. Apart from the familiar technical sense of creating complex sounds from simple waveforms, synthesis also describes what we do when we take our influences and inspirations and make them the foundation of our own musical voices.
Of course, influences and inspiration can come from anywhere, and as with any flow of information, filters are needed to fish out what is potentially useful. Increasingly, algorithms are doing a lot of the filtering for us (Spotify playlists, Youtube recommendations, etc.) – and while the machines are getting better and better at predicting what might interest us based on our past behaviour, nothing beats being personally led into a musical world one didn’t even know existed and immediately falling in love with it.
Where are you two from and how long has Visible Cloaks been a going concern? It’s a very mixed bag. Music Theory. SoundGym Doctor: Test Your Ears. Untitled.

Tvísöngur sound sculpture in Seyðisfjörður, Iceland. Photography: courtesy of Visit Seyðisfjörður It is all too easy for architecture to be seen and not heard. Instragrammable visuals may be at our fingertips, but it is impossible to photograph an echo. Sad news, considering the most memorable of spaces are those that heighten more than just our optical sense. What’s more, much of new architecture is focused on controlling sound, rather than celebrating it. Here are 10 spaces to remind us of architecture’s acoustic abilities – from the unexpected quarry opera venue to the deliberate forest megaphone. 1.

Interactive Frequency Chart - Independent Recording Network. 120 Years of Electronic Music | The history of electronic music from 1800 to 2015. 120 Years of Electronic Music* is a project that outlines and analyses the history and development of electronic musical instruments from around 1880 onwards. This project defines ‘Electronic Musical Instrument’ as an instruments that generate sounds from a purely electronic source rather than electro-mechanically or electro-acoustically (However the boundaries of this definition do become blurred with, say, Tone Wheel Generators and tape manipulation of the Musique Concrète era).
The focus of this project is in exploring the main themes of electronic instrument design and development previous to 1970 (and therefore isn’t intended as an exhaustive list of recent commercial synthesisers or software packages.) Modes of interaction for performers and composers: Atonality and just intonation as a theme in instrument design.

Hear Seven Hours of Women Making Electronic Music (1938- 2014) Image via Flickr Commons Two years ago, in a post on the pioneering composer of the original Doctor Who theme, we wrote that “the early era of experimental electronic music belonged to Delia Derbyshire.” Derbyshire—who almost gave Paul McCartney a version of “Yesterday” with an electronic backing in place of strings—helped invent the early electronic music of the sixties through her work with the Radiophonic Workshop, the sound effects laboratory of the BBC. She went on to form one of the most influential, if largely obscure, electronic acts of the decade, White Noise.
And yet, calling the early eras of the electronic music hers is an exaggeration. In recognition of this fact, musician, DJ, and “escaped housewife/schoolteacher” Barbara Golden devoted two episodes of her KPFA radio program “Crack o’ Dawn” to women in electronic music, once in 2010 and again in 2013.

The "Amen Break" and Golden Proportion. The Amen Breakand the Golden Ratio by Michael S. Schneider M.Ed. Mathematics Author of A Beginner's Guide To Constructing The Universe A student recently asked if I had any insights into why the "Amen Break" is so popular in some modern music.
"What's that? " Click on this picture of its audio waves to hear the Amen Break in a work. The "Amen Break" is 5.20 seconds long in four bars. A history of the Amen Break can be found here, and the term googled here and here. A video explaining the Amen Break can be found here. What I first noticed in the wave picture are the distinct peaks representing the beat. Having looked at the geometry of the Golden Ratio a great deal, and its expressions in worldwide art, I have a decent sense of its place along a line.
For more exact visual analysis I examined the wave image in my computer, in which I have a palatte of geometric forms and proportions for quickly identifying an object's ratios. (c) 2007 Michael S.

According to scientists, This is the most relaxing tune ever recorded. This eight minute song is a beautiful combination of arranged harmonies, rhythms and bass lines and thus helps to slow the heart rate, reduce blood pressure and lower levels of the stress. The song features guitar, piano and electronic samples of natural soundscapes. A study was conducted on 40 women, who were connected to sensors and had been given challenging puzzles to complete against the clock in order to induce a level of stress.
Different songs were then played, to test their heart rate, blood pressure, breathing and brain activity. The results showed that the song Weightless was 11 per cent more relaxing than any other song and even caused drowsiness among women in the lab. It induced a 65 per cent reduction in overall anxiety and brought them to a level 35 per cent lower than their usual resting rates. Moreover, sound therapies have been used for thousands of years to help people relax and improve health and well-being. The top ten relaxing songs are known to be 1.
