Audio enthusiasts are not only interested in audio technology to compare, and knowledge of acoustics term also has a keen interest. Our web site to introduce a lot of knowledge about sound terms, if you need related columns view can go to our web site. In today's audio terminology knowledge we mainly to introduce the following contents:

First look at what is in terms of sound is pure tone:

A sound term refers to the voice of the sine signal, on hearing is a clear single tone of voice, like the sound of a tuning fork.

The second audio sound transmission gain

The term some audio and audio enthusiasts understand better it is when using microphone sound reinforcement system, put a lot of microphones pick up sound, is the sound amplification system feedback noise level of the important indicators, the higher the sound transmission gain, acoustic feedback noise is smaller (less), microphone sound a lot more. Calculation method is turned into the microphone volume (audio feedback phenomenon), one is put in front of the microphone sound source, measure the sound field and a microphone sound pressure level at the same time, with the sound field in the sound pressure level minus the microphone sound pressure level, taken the sound transmission gain of the sound reinforcement system.

Finally to introduce the knowledge of the term is the error of tape speed:

Recorder of actual tape speed and the percentage of the relative error of tape speed, rated generally affordable cassette recorder of the error of tape speed should be within the plus or minus 3%, professional recorder for tape speed error in positive and negative o. within 3%.

In today's audio terminology knowledge section we have and your audio enthusiasts to share this knowledge is the most simple three terms. I really like this knowledge, if you have this information might as well take it out and share with us, together we harvest.
