Talk about the sound field in detail

The first article of the three dimensions of the sound of the article by a lot of friends support and encouragement, thank you very much. Personally feel that many friends now, whether it is burning headphones Ye Hao, playing the cover of the Ye Hao, or burn box Ye Hao, many basic concepts are very vague, of course, the sound of this subject more subjective, and many details of the Things really need to take the time to pondering to understand, the language sometimes difficult to describe clearly. But how to say, there is a beats earphones basic guidance at least on the understanding of this thing is good, personally think that these things have a little understanding, come out and share with you, hoping to give you something.

Today, we often talk about the "sound field" is a thing. I may have the impression of a friend beats by dr dre who looked at my last issue. I mentioned the three dimensions of the sound, the left and right, the upper and lower, and the front and back. The sound field, in fact, is composed of three things the entire acoustic space. Of course, now the mainstream argument in the sound field is only horizontal and vertical to represent, that is, around and before and after. So today it is not so complicated first, from the left and right and before and after the two words that sound field.

The sound of the left and right we are actually very well understood, and the left to the right of the width, it is equivalent to the width of the sound field, also known as the width of the horizontal sound field. For the speaker, the sound field width and speaker placement and listening position, the environment, as well as the speaker itself has a relationship. For the headset system, the sound field width is already fixed. The specific width of each person to hear, is not the same, why? First of all, each person's ear structure is not the same, so that each person to accept the sound is not the same, only one by one to describe. Some open headphones are not obvious on the edge of the lateral, it is because the unit of vibration of the air part of the air is completely from the other side of the spread, you can float very far. Of course, for most of the energy, there is a similar border, what is the border, it is equivalent to you make a voice only the left channel, the sound can reach the left of the location, which is Left border, same right border. The distance from the leftmost sound to the rightmost sound is the width of the sound field.

Around, that is, horizontal sound field to understand, but for many friends, vertical, that is, before and after the sound field is not very good understanding. I was able to hear and can simply control the vertical sound field has also been a long time after a training to find, in fact, the vertical sound field is what a thing, that is, before and after the sound level. For the sound system, the vertical is very obvious, in general, the sound of the diaphragm is the sound of the front position. (Sometimes there will be off the box and the like, for the time being do not consider), and then with the sound reduction, high frequency reduction, reverberation increase and direct sound reduction, the sound will be followed by the back. Here to explain a few terms, first, reverberation. Everyone in a quiet environment can make a try, quickly cough, you will find your voice will not stop soon, but there will be a process of continuous decay, in the general room will continue to compare Short, and if the corridor, underground passage, or a bath in the sub-sub-this will last longer, this thing is reverberation. The judgment of the human ear is based on reverberation. Second, direct sound and reflection. We have to make a hypothesis, you stand inside a house, in front of a microphone, you cough, the microphone will put your entire sound completely included, of course, that is, your voice directly to the microphone part, you have The sound through the walls, the ground and even your girlfriend's chest reflects the part of the microphone, (play the audio where the girlfriend) is the part of the reverb. So, the direct sound is your voice directly to the microphone part, remember this just fine. Having said that, in the process of recording music, the music producer will be recorded in real, or the level of the sound, then the sound of the vertical out

The depth of the vertical sound field is how to define it, that is, from the equipment can play the most front of the sound, and the distance between the sound of the last, this is the depth of the vertical sound field. Many times the most voices are no boundaries, and here and around the same, pay attention to a general position, there is no way to accurately locate.

Horizontal and vertical sound field is basically here, but must remember that beats earphones the sound field of this thing is not just a two-dimensional thing but a three-dimensional thing, by the frequency of the upper and lower impact on the sound field, For example, some equipment, high-frequency sound field will be wide, and some devices will be low frequency sound field, this requires everyone to slowly understand the.

And then talk about the shape of the sound field. The sound field of the speaker is mostly fixed, rectangular it Headphones have a variety of sound field, for example, the square, that is about the width of the left and right and almost the same depth, while the width of the left and right will not change with the front and rear. Round, left and right width and front and back depth is almost the same, but with the sound level changes, the width of the left and right will change, oval, that is, the width of the left and right than before and after the larger. There are many wonderful shape, of course, no one can accurately determine the specific shape of a sound field, because they are changing, can only talk about a general. Of course, some say that the sound field is spherical or ellipsoid or rectangular cube that is the impact of the upper and lower frequency factors are taken into account, and is correct.
