Many of us have thought about what is sound. In physical terminology this value is described as a wave formation in air pressure. Simply put, without air we would not have heard. The ability to perceive sounds is due to the sensitivity of our ears to sound waves. We feel changes in air pressure.
What is the sound, you can understand with a little experiment. Clap your hands in front of his face. In addition to sound, you will feel a slight breath of air. The distribution of this air flow similar to sound propagation. A sound wave is created by pushing air through the cotton in her hands.
The Ability to hear causes people to wonder and explore the acoustics. This science describes the laws of sound propagation and gives a General understanding of what is sound. Studying the literature, websites and various articles, ‘sound fans” has repeatedly faced with a variety of concepts. One of them is a warm tube sound.
This concept was discovered a long time ago, during the opening of semiconductors. Reflection was the high price of transistors. People have been looking for some alternatives.
The Tube sound is so called due to the transistor amplifiers that were rich in odd harmonics, allowing to designate the timbre of the sound. This effect was due to play on vacuum tubes, hence the name.
Due to the fact that melody was trying to play on the tubes, the audio signal characterized by a small number of harmonics is mainly dominated by the fourth, third and second. Output noise was very “soft”, also called “warm”.
