Fractal geometry of music

Abstract   Music critics have compared Bach’s music to the precision of mathematics. What “mathematics” and what “precision” are the questions for a curious scientist. The purpose of this short note is to suggest that the mathematics is, at least in part, Mandelbrot’s fractal geometry and the precision is the deviation from a log-log linear … Read more

DML Speakers so good — panels of acoustic ceiling tile and extruded polystyrene

https://www.youtube.com/watch?v=jjZHFIdfUFk   Helium gas inside enclosure.  Overall +2dB gain as speaker back-pressure is reduced.     Anechoic chamber response — blue/purple is speaker-forward facing; red is speaker-rear facing (into absorptive lining).     Ported vs Sealed.  Ported gives overall more bass output (+5dB), all other factors approximately equal.  Green is ported; blue/purple is sealed.   … Read more

Math and Geometry of Music: Linking Sight and Sound

Languages were perhaps once ‘sung’. By Daniel Arthur – “Ancient alphabets were constructed by using visual symbols to represent sounds. Ancient sacred architecture was constructed to send and receive those sounds to and from the gods. Because of that, ancient languages, like Egyptian, Hebrew and Greek were more poetic and musical than our own, with … Read more
