Recent revolutionary discoveries of the Argentine-Italian researcher Hugo Zuccarelli have extended the holographic (holographic) model to the world of acoustics.
Hugo Zucarelli is the inventor of holophonic (holophonic) sound technology.
For reasons of patent secrecy, he still has not made public the information necessary to fully understand his important discovery. In the rest of the presentation, I use the materials of the lectures that I listened to and my own experience of listening to holophonic sound during a three-day seminar in Milbra, California, in which my wife Christina and I took part.
In childhood, unfortunately, Zukarelli survived the shock when he was nearly hit by a car. His ability to accurately localize the sound of an approaching car saved his life without seeing it. This aroused his interest in the problem of how various animals localize sound in their perception. After a thorough study and analysis of the mechanisms by which animals of various species achieve accurate identification of sound sources, he came to the conclusion that existing hearing models Continue reading
In recent years, technologies in the field of creating spatio-temporal effects have improved significantly, and we can talk about significant progress in this area. We owe this progress to scientific research in the field of acoustics and psychoacoustics, the development of new methods for synthesizing sound space and new reverb algorithms.
Reverb (from the Latin word re-verberatus, “re-strike”) is the process of continuing sounding after the end of a sound pulse or oscillation, due to reflections of sound waves from surfaces. Therefore, reverberation takes place only in enclosed spaces, although under special conditions some of its types can also occur in half-open space (for example, in a stadium, city square, narrow mountain gorge, etc.). We can justifiably attribute to indoor spaces such a natural formation as a cave – that’s where the reverb is so reverb! Continue reading
Graphic equalizer is a multi-range corrector of the amplitude-frequency characteristics of electric sound signals. The boundaries of the full range of frequencies in which the amplitude-frequency characteristic is corrected are determined by the range of frequencies perceived by the human ear. The lower limit of this range is sound vibrations with a frequency of 20 Hz. (oscillations per second), and the upper – 20 KHz. (thousand oscillations per second).
The graphic equalizer, depending on its accuracy, determined by the width of one band, may contain a different number of ranges in which the values of the amplitude-frequency characteristics are set. For example, with a bandwidth of one octave, the equalizer will contain 10 bands, with a bandwidth of 1/2 octaves – 15 bands, and Continue reading
