Every sound space is as if everyone has its own distinct sound characteristics. People will have different voices due to the structure of the vocal cords and the different resonance of the abdominal cavity of the thorax. Similarly, each sound space will have its own unique sound characteristics due to different space sizes, proportions, and upholstery. In other words, there are very few people whose voices sound the same: Similarly, it is seldom possible for two speakers to sound the same. So even the same audio equipment, in different sound spaces, will have different sound characteristics. Successful sound space will create a charming charm of the sound. The following for everyone to introduce audio technology in the formation of sound space 12 guidelines.
First, the soft tone space is more suitable for listening to music
Floors, ceilings, walls with plywood, gypsum board or plank into the space is soft-tune the space to the reinforced concrete or hard-filled space that hard space. At present, most of the living environment in our country belongs to hard-tuning space
Because hard-key space can not properly absorb excess treble and bass, resulting in listening to music when the treble is too harsh or bass is too boring shortcomings. Although the soft tone space may also have the disadvantage of insufficient bass absorption and solid bass, however, it has been proved that the soft tone space is still suitable for listening to music.
Second, reflection, absorption and proliferation of the three clever use
Careful deployment of reflection, absorption and diffusion of sound waves, the purpose is to get warm, full, soft, rich, clear, transparent voice.
Third, large space is better than small space
The larger the volume of the larger space, sound waves emitted by the speaker by the border (six walls) less affected by the distortion, the sound is more correct. In a large space, if you can deploy properly, the resulting sound will be more relaxed, uniform and correct, and the bass dive deeper. As for the standing wave, although the large space can not be completely avoided, the degree of harm is relatively low.
Fourth, equipment should be appropriate
Each sound space will have its own sound characteristics. These sound features also need to cooperate with the appropriate speakers, can play the effect of saffron. Acoustic space layout better, with a wider range. Conversely, if the sound space is not well-arranged, only a few devices can be found to accommodate such a biased space. Different space sizes, with a different speaker. In a small space with large speakers or large space with a small speaker will be futile. It depends on a wealth of experience to achieve the perfect result.
Fifth, rational enthusiasts should be exclusive to a minimum
Every audiophile will inevitably be negative because of long-term sound space in their own, and have their own listening habits and preferences, and based on these habits and preferences, to judge others sound space and listening habits, preferences, it is easy to make negative judgments of others . Therefore, when you hear different voices, do not make any exclusive comment at first. Instead, you should try to find out the advantages of the acoustics of others.
Sixth, try hard to transform the space for the soft tune space
If you want to hard-tune the space into soft space, you can first transform the four walls. For example, gypsum board nails into the mezzanine, mezzanine covered with glass fiber cotton. This will not reduce a lot of mezzanine space, but also can improve the sound insulation. The reason for using gypsum board or plywood is that it is easy to absorb the midrange sound due to the thin plywood or the wooden heart board, and the gypsum board has more negative effects on the listening music due to the heavier and more absorbed bass. In addition, the gypsum board is a fireproof material, used to make the sandwich more secure.
Seven, the second residue diffuser is very easy to use
Diffusion is the sound waves emitted by the speaker no matter from where the direction of injection, will be evenly reflected in all directions. The general acoustic reflections are usually directional. Theoretically, as long as the length of the reflecting surface is longer than the wavelength of the acoustic wave, all the acoustic waves with shorter wavelengths than the reflecting surface will be reflected in a certain direction. Sound space needs diffusion, not directional reflection. Because the dispersion will make the room more uniform sound waves, and directional reflections will only have a partial impact.
Eight, sound space sound effects should be based on live music standards
Sound space sound effects standards are not the only, but multiple. The standard of sound effects is based on the performance of the live music. The sound of live music is not unique, but multiple. As far as classical music is concerned, there are many outstanding concert halls in the world, each of which has different sound characteristics. Some warmth, some full, some crystal clear, and some bass-rich, surrounded by a good sense of sound, the sound characteristics of these concert halls have their own strengths.
Influenced by the unknowable sound characteristics of the recording site, the sound characteristics of the recording equipment, the sound characteristics of the replay equipment and the sound characteristics of the sound space, enthusiasts can only rely on the performance of live music and are multiple standards.
In nine, standing wave should only take
The standing wave is the space resonance phenomenon, so long as the distance between two opposite parallel walls is equal to the integral multiple of the half wavelength, resonance occurs and a standing wave occurs. If the standing waves generated by three groups of parallel walls in space have frequency overlap, a stronger standing wave will be formed. Standing waves do not have more than a single frequency, and their frequency range is so wide that one can not exactly "offset" it with some measure. At the same time, the standing wave is very energetic, usually much higher than the sound pressure of normal music, and therefore can not be countered with the "fine-tuning" tuning technique. The best way to deal with standing waves is to use speaker placement and change the listening position to avoid it. "Ten, space for surface treatment
The sound space from hard to soft tune, then follow the "hard before, after suction, after the proliferation of" method of surface treatment. The so-called "front hard" refers to the front of the room (between the rear speakers and speakers) try not to add absorbent material, or you must increase the output power amplifier will make the sound solid. If the amplifier output power is not large, the speaker is not very large, do not suggest plaster board back wall. The so-called "suck in", that is, between the speakers and listening position on both sides of the wall for sound-absorbing surface treatment. The purpose is to attenuate the first reflections, improve positioning and clarity, and avoid too loud or jarring sounds. "Suck in" a lot of practice, the cheapest and effective material is glass fiber cotton. Take glass fiber cotton 5 cm thick and 20 kg / m 3 as an example, it has a sound absorption of up to 85% at frequencies above 500 Hz. Fiberglass bag can be wrapped (do not be exposed), as the image frame shape, a very good effect on both sides of the wall for the first time reflection of sound absorber.
The so-called "post-proliferation" is to listen to the location of the back wall to spread the area. The correct approach is to put two diffusers on the two corner walls of the rear wall, and put a diffuser plate at the center of the rear wall to exert the true effect of diffusion. After the sound waves have been evenly spread, the sound waves reflected throughout the listening area are averaged, and the listening position is not limited to the "Emperor"; but the sound quality, the sound, the sense of depth and the depth of the sound can be remarkably improved.
Eleven, space decoration skills
Indoor items will absorb and reflect the sound waves, play the role of natural reverberation. The heavier items absorb more of the low-frequency or low-frequency, and sometimes can reduce the impact of low and medium standing waves. The surface of multi-fiber, porous soft items have a strong absorption of high-frequency role, such as the surface of velvet sofa, carpet velvet and so on. It is noteworthy that the various audio and video home is best not to glass doors.
Twelve, quadratic residue diffuser has a special diffusion characteristics
If it is centered on the center frequency, its diffusion limit may extend down to about half the frequency below the center frequency (if the center frequency is 1000 Hz and half-frequency is 750 Hz), the upper limit may be up to the center frequency of N- 1 times. Assuming a center frequency of 1000 Hz and a step of the quadratic residue diffuser of 7, the upper limit of the diffusion range is about 6000 Hz.
