why you need acoustic treatment and acoustic report?  -  partition wall
We live in an international community where too many of the best sound structures are now very cheap, but few people realize that even the first one
The rate device can be compromised by means of negative room acoustics.
You may think that you are just listening to your speakers, but what actually reaches your ears is a mixture of the direct sound of the speakers plus the infinite sound reflection of all the hard surfaces in the room, walls, ceiling floors and furniture are included.
To prevent the room from sounding unnaturally useless, some sound mirroring is required, but you will be intoxicated with the problem that the bass sounds muddy before being carefully controlled, the clear notes in the bass line sound louder or quieter than they should be, lack attention in high and blurry stereo imaging, and it's hard to tell where the sound report should come from.
Attach the carpet to the partition, which is a problem often encountered in the "enthusiastic" studio.
The carpet seems to dry the sound. why not?
The fact is that the effectiveness of the "hole" acoustic absorber is related to its physical thickness, in which case the low frequency must be treated (bass)
Reflection is higher than frequency.
The carpet will dry the excessive frequency, but there is little in the mid range, and there is no effect at all at low frequencies, so you grow into a room controlled by the middle and coffee frequencies, produce a voice of oppression.
The perfect scenario is that acoustic therapy works well at all frequencies so that room reflections can be controlled without losing the usual sound balance.
It is also crucial to understand the differences between acoustic treatment and sound insulation, as they are two very separate disciplines.
It may also improve the sound insulation effect by filling the gypsum board layer with mineral wool or into the partition wall, but it has little or no impact on room acoustics.
Instead, use acoustic remedies for the room so you can enhance the hearing around it, which doesn't help to prevent sound from coming in and out of the room.
There are several ways to design a sound absorber, some require accurate calculations in order to be customized according to precise room failures, and others are designed to be applied in an extra intuitive way.
The porous absorber is very powerful at medium and high frequencies, and suitable materials include mineral wool, fiberglass and acoustic foam.
All of these paintings are done by letting the air pass through the material and drop the vibration energy like this.
In particular, through the loss of friction in the fabric, sound energy is converted into heat, although the heat generated is very small.
Due to the absorption of a considerable part of the sound and electricity, there is almost no reflection back in the room.
A porous absorber with a thickness of 50mm will effectively prevent excessive and higher intermediate frequencies, while a porous absorber with a thickness of 100mm will cover both high-end and most intermediate varieties.
With the help of the spacing between 25 and 100mm, the foam is away from the wall, leaving an air hole on the back, and also improves the foam's ability to absorb at a lower frequency.
As the frequency decreases, the amount of electricity absorbed by these porous panels decreases periodically, so a special approach must be taken to deal with low frequency faults.
