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 sense changes in air pressure.
What is sound can be understood with a little experiment. Clap your hands near your face. In addition to the sound, you will feel a slight breath of air. The distribution of this airflow is similar to the distribution of sound. A sound wave is created by expelling air through the clap of your hands.
The ability to hear makes people interested and explore acoustics. This science describes the laws of sound propagation and provides a general understanding of what sound is. Studying literature, websites and various articles, “sound fans” have come across a variety of concepts more than once. One of them is a warm tube sound.
This concept was discovered 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 has such a name due to the use of transistor amplifiers, which were rich in odd harmonics, which allowed us to denote the timbre of the sound. This effect was obtained due to reproduction on electronic 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. 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 ham, it became fashionable to have their own battery-powered radio.
The concept of warm tube sound is still alive today, there are many circles of radio amateurs who still reproduce sound waves on electronic tubes. Only in contrast to 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 old sound instruments can easily distinguish between a vacuum radiol and modern technology.
On the Internet, people who have a concept 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 fans of this sound. Yes, of course, with the development of technology, such people have become much smaller than before, but still this is the story of not only music, but the whole acoustics. The sound on the tube equipment is unusual and unique, it will always be the sphere of interest of any self-respecting music lover.
