Capacitor Motor,Furnace Capacitor,Start Capacitor,Capacitor Start Motor Wentelon Micro-Motor Co.,Ltd. , https://www.wentelon.com The home listening room should have both good acoustic performance and a beautifully decorated living room with a warm atmosphere. To this end, several suggestions for renovation were proposed.
Door and window processing
The purpose of handling doors and windows is to separate sound, sound and dust. A lot of noise enters the room through doors and windows. A good wooden door can reduce the indoor noise level after the door is closed (10-20) db. If the door frame is covered with a sealing strip, the noise level (14-18) db can be reduced. If the outdoor sound is noisy, it is recommended to install double-glazed windows.
Generally, the width of the living room window sill is about (12-15) cm, and a glass window can be added to the edge of the window sill to protect against dust, noise and warmth. Double glazed windows reduce outdoor noise (14-18) db; if covered with a sealing strip, it can be reduced by (18-20) dB. If the conditions permit, aluminum alloy window can be installed to make push-pull type, save space, easy to use, not easy to deform, good sealing performance, and its performance is better than steel window. If the air conditioner is installed in the home, the air conditioning duct is the inlet air outlet and the noise inlet; if the TV room antenna is installed, the antenna inlet is also the noise entrance. These pipes should be silenced with extreme interfaces. Curtains, curtains and tapestries are important sound absorbers, and they are more delicate and luxurious decorations. The use of velvet and velvet as curtain material and curtain material can reduce the reflection of sound waves and the resonance of glass windows. The sound absorption coefficient of the velveteen curtain is 0.31-0.47, the sound absorption coefficient of the curtain made by the medium and long fiber is 0.15-0.27, and the double-layer velvet has the largest sound absorption coefficient of 0.69-0.82.
2. Indoor side treatment
Sound and sound absorption should be handled on the ground. It is best to lay a carpet, which is ideal for sound absorption and sound insulation. Generally, ordinary woven carpets are about 0.5-0.71, while real wool rugs have a sound absorption coefficient of about 0.68-0.82. It is better to set up the wooden floor. If it is limited to the conditions, it can be changed.
The sound absorption coefficient of wooden floors is about 0.03--0.05. Sometimes people are willing to lay plastic bricks or tiles, their sound absorption and sound insulation performance is poor, the sound absorption coefficient of plastic floor is 0.02=--0.04, terrazzo scene sound absorption The coefficient is about 0.01--0.03. The ceiling is also an important way to introduce noise. Those with poor quality and thin slab ceilings are easy to transmit the roof, beautiful and soundproof, with little impact on the height of the room.
Also deal with the four walls. Ordinary walls are dry plastered brick walls. The sound absorption coefficient is very small. About 0.02--0.04 can make four walls into wooden walls; or make wooden wall skirts with heights (0.8--1) m, wall skirts. Keep a certain distance from the wall, not less than 4cm, form a cavity between the walls, which can increase the low-frequency sound absorption effect. There are many kinds of concrete wall skirts. Users can also create new ones. If you can change the wall into a wave, arc, patch, etc., you can improve the acoustics in the interior. condition. Usually the walls are white or sprayed with ash, spray paint, color spray or other paints, and their sound absorption effect is similar. In addition, the condition can be concerned with the decorative cloth on the wall, and the wall cloth is suitable for the wall (3-5) cm. This kind of wall cloth can enhance the sound absorption and beautify the living room.
3. Interior furniture
(1) Typical data
Many home listening rooms can enjoy music and receive guests, to achieve the unification of audio-visual enjoyment and aesthetics. At present, the height of the ordinary room is relatively low, only (2.4-2.8) m. In order to balance the listening effect, the length and width should be close to 1.7:1. Generally, the area of ​​the listening room is more than 15 square meters, so that when the stereo is reproduced, the distance between the two speakers is about (2-2.5) m, which is advantageous for expanding the stereo image group.
(2) Display skills
The placement of indoor furniture should strive to be convenient to use and elegant in the living room. When placing furniture, try not to take a symmetrical shape to prevent acoustic dyeing. Do not place objects that cause vibration, such as metal paintings, thin and light shells, etc., and their vibration will affect the sound reproduction effect. The combination of cabinets, bedroom cabinets, large sofas, etc. in the room is very effective in improving the sound absorption effect, especially for improving the low frequency effect. The perforated plate resonator cannot be installed in the general room, so it is not convenient to absorb the low frequency. This shortcoming can be overcome after placing the wardrobe. Acoustic conditions can be improved by hanging thick curtains on glass windows, wall hangings, carpets on the floor, bedspreads on the bed, etc. The curtains have better transmission performance to low frequencies, while the glass windows have better sound absorption performance for low frequencies, and they have complementary functions.
(3) Fine tuning of reverberation time
The indoor reverberation time should be controlled within a certain range. If the reverberation time is too long, the sound has tailing, echo, and the sound absorption can be increased by laying carpets, hanging decorative curtains, etc., and even indoor furnishings, dolls, velvet toys, flower pots, etc., can improve the sound absorption effect. If the indoor reverberation time is too short and the sound is dry, the reflective surface should be added, and the glass mirror and the picture of the large glass frame can be hung to improve the sound quality of the room. There are still many ways to improve the sound quality. For example, indoor hanging various chandeliers, wall-mounted stickers or hanging crafts, etc., not only beautify the environment, but also improve the reflection characteristics.
Some enthusiasts have placed bookshelves indoors, and bookshelves are filled with books and magazines of different sizes, CDs, and analog records. These items are absorbent, reflective, and dispersive to sound waves; The layers are protected by books of different sizes and widths, which can produce irregular surfaces. For large-area reflective walls that are difficult to handle, try to place the bookshelf and improve the listening experience. In short, through various adjustment measures, people finally hear the sound of the speaker sounding harmonious.
