Many of us have repeatedly thought about what sound is. In physical terminology, this value is described as a wave formation of air pressure. Simply put, without air, we would not hear anything. The ability to perceive sounds is due to the sensitivity of our ears to sound waves. We feel changes in air pressure.
What sound is can be understood with a little experiment. Clap your hands next to your face. In addition to the sound, you will feel a slight breath of air. The propagation of this air flow is similar to the propagation of sound. The sound wave is created by expelling air by clapping your hands.
The ability to hear makes people interested and explore acoustics. This science describes the laws of sound propagation and gives a general understanding of what sound is. Studying the literature, websites and various articles, "sound fans" have often come across a variety of concepts. One of them is a warm tube sound.
This concept wasdiscovered a very long time ago, at the time of the discovery of semiconductors. The reason for reflection was the high prices of transistors. People were looking for some alternatives.
Tube sound got its name from the use of transistor amplifiers, which were rich in odd harmonics, which made it possible to indicate the timbre of the sound. This effect was obtained by playing on vacuum tubes, hence the name itself.
Due to the fact that they tried to play melodies on radio tubes, the sound signal was characterized by a small number of harmonics, mainly the fourth, third and second dominated. The output sound was very "soft", it was also called "warm".
Over time, transistors began to actively become cheaper, and in radio amateur circles it became fashionable to have your own battery-powered radio.
The concept of warm tube sound is alive to this day, there are many clubs of radio amateurs who still reproduce sound waves on vacuum tubes. Only unlike the old days, when transistors were in short supply, today they are in abundance. Basically, this hobby is typical for people who consider themselves lovers of vintage style.
It is worth noting that the sound on semiconductors is significantly different from what we hear when playing on tube equipment. Therefore, an avid music lover who collects vintage sound devices can easily distinguish a vacuum radiogram from modern technology.
On the Internetpeople who have an idea of what sound is, very often on their blogs recall the old warm sound. On the World Wide Web, you can find many forums that are dedicated to lovers of this sound. Yes, of course, with the development of technology, such people have become much less than they used to be, but still this is the history of not only music, but all acoustics. The sound on tube equipment is unusual and unique, it will always be of interest to any self-respecting music lover.
