Improve sound in the home theater / audio room for more impressive and realistic feeling
The article that we uploaded earlier, “How to improve the sound of the audio by 10 times” , became the number one accesses last year. As much as that, I think that there are more people who are interested in the surrounding sound environment. Since two years have elapsed since we uploaded the article, I will supplement new information.
Reflection sound of space is very important in enjoying sound in home theater and audio room. No matter how beautiful the picture you are viewing at home (even 4K, 8K), I think that you can not get a satisfaction when watching in a bad sound space. Because the visible part is easy to understand, it is likely to emphasize technology of image only. However, by improving even the part of the sound in the same way, you can have impression and realism.
For familiar things, curtains and carpets with long hairy feet have the effect of reducing the reverberation of the room. Conversely desks, shelves and racks echo the sound so you can adjust the reverberation time by installing it away from the sound source as much as possible. In particular, immersive audio (immersive feeling) has been attracting attention for the past two years.
Immersive audio : a mechanism to produce an immersive feeling in sound
Immersive audio is not only enjoying sound but also a mechanism and space that make it feel like being in the space that you can actually hear the sound. For example, when listening to a classic, direct a feeling (immersive feeling) as if the player in front of you is playing. Until now it was a need only for professional mastering and recording engineers, but now it is being introduced to private homes as well.
Not only the sound but also the video is the same. It is a feeling that the sight that is on the prairie and the ship is spreading in front of you. It is different from the previously popular 3D television, and it will be a new way to enjoy. In the case of immersive, it is necessary to make the reproduction space an extraordinary space. The sound of the chapel above creates a mysterious space, but in the case of general homes, it is difficult to use unevenness of the ceiling and a large space, so supplement this part with acoustic material.
Regarding the location of the sound absorbing material, coping with the flutter echo on the back of the audio is effective. By treating the basses coming in the corner of the room, the whole sound is clean. Up to this point is the same as improvement of the reverberation sound so far, but if you aim to further immersive space, you can feel the spread of the space by installing sound absorbing material behind yourself.
“SHIZUKA – SDM” which was released at “InterBee2018” held in Makuhari Messe in 2018 is a foldable and lightweight sound absorbing panel, so it can be placed in the back of the seat or in the corner of the room. In the case of audio, you can adjust the way you hear to your liking by changing the position of the sound absorbing panel according to the music you listen to.
