What is sound and, in particular, a warm tube sound

Many of us have repeatedly thought about what sound is. In physical terminology, this value is described as the wave formation of air pressure. Simply put, without air, we would not have heard 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, you can understand with a little experiment. Clap your hands near your face. In addition to sound, you will feel a slight whiff of air. The spread of this airflow is similar to the propagation of sound. A sound wave is created by pushing air through clapping hands.

The ability to hear makes people wonder and explore acoustics. This science describes the laws of sound propagation and gives a general understanding of what sound is. Studying literature, sites and various articles, "sound fans" have repeatedly faced with various concepts. One of them is a warm tube sound.

This concept was discovered a long time ago, at the time of the discovery of semiconductors. The reason for thinking was the high prices of transistors. People were looking for some alternatives.

The lamp sound has this name due to the use of transistor amplifiers, which were rich in odd harmonics, which made it possible to denote the timbral coloration of sound. Such an effect was obtained due to reproduction on electron tubes, hence the name itself.

Due to the fact that the melodies were trying to play on the radio tubes, the sound signal was characterized by a small number of harmonics, mostly dominated by the fourth, third and second. At the output, the sound was very "soft", it was also called "warm".

Over time, transistors began to actively become cheaper, and in the circles of radio amateurs it became fashionable to have a radio receiver on batteries.

The concept of a warm tube sound is alive to this day, there are many circles of radio amateurs that still reproduce sound waves on electron tubes. Only in contrast to the old times, when transistors were in short supply, today they are in abundance. Basically, this hobby is typical for people who refer themselves to fans of vintage style.

It is worth noting that the sound on semiconductors is significantly different from what we hear when playing on the tube equipment. Therefore, an avid music lover, who collects ancient sound instruments, can easily distinguish a vacuum radio from modern technology.

On the Internet, people who have an idea of what sound is, very often on their blogs remember the ancient warm sound. In the World Wide Web, you can find many forums that are dedicated to fans of this sound. Yes, of course, with the development of technologies such people have become much less than before, but still it is a story not only of music, but of all acoustics. The sound on the lamp equipment is unusual and unique, it will always be the sphere of interest of any self-respecting music lover.
