While listening to a piece of music, focus and try to “see” what the music portrays. If this, for example, is “The Seasons” by P. Tchaikovsky, then you may see an autumn landscape, a flying three, an awakening nature, a lark ringing in the sky. When listening to a song, one can always “finish” in the imagination what is more suitable for it: the wide expanse of the landscape, festivities …
Music, like any art, conveys the thoughts of the person who created it, the thoughts and feelings of those whom it depicts (in song, dance, opera, symphony). Compare the sounds in the music with the colors in the painting or the melody with the lines in the picture. And to make it even more interesting, draw what you 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
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
