Hugo Zucarelli and Holophony

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

Acoustics Studios

To describe sound fields in acoustics, the sound pressure p, measured in Pascals (Pa), is widely used. As with electrical quantities in sound engineering, it is usually more convenient to use a logarithmic scale here. At the same time, the concept of sound pressure level (SPL) is introduced L = 20 log (p / p0), where p0 = 2 x 10-5 Pa is the sound pressure at the threshold of audibility. Very often, ultrasound is measured (or calculated) in separate frequency bands. The most widespread are octave or 1/3 octave bands with a relatively constant bandwidth. Geometrical average (below in the text for brevity, average) frequencies of these bands are regulated by international and domestic standards. A preferred range of mid frequencies for octave bands: … 125, 250, 500, … Hz; for 1/3 octave bands: … 125, 160,200, 250, … Hz. In addition to these narrow frequency bands, broadband correction is also applied, the form of which is Continue reading

Microphone for home music studio

Which musician did not encounter the problem of choosing a microphone ‘Often, when they come to the store, most of them simply don’t know what their microphone should be like. Why is a capacitor better or worse than a dynamic one, in which cases to take the “eight”, and in which cases – the usual cardioid, and so on … Eyes run wide, and as a result of the huge assortment the choice falls on anything, but not what really necessary. But actuallychoosing a  microphone is not so difficult. Walking through the windows, you should mainly pay attention to only three points – type, orientation and frequency range – in case you select a microphone for a specific instrument or voice.

Suppose you have decided on a frequency range, since today there are many universal microphones that can work well with a large number of different tones. Now let’s find out which type of microphone is most suitable for your working environment. There are two types of microphones used today – dynamic and Continue reading
