Guiyang sound-absorbing soft bag manufacturer

Guiyang sound-absorbing soft bag manufacturer anastomosis effects: acoustic wall after contact, except wallboard forced vibration in the vertical direction, as well as along the direction of the board forced bending vibration. Over at a particular frequency, forced bending vibrations inherent freedom and plate bending vibration hair match, then board is very obedient to follow incident acoustic bent, causing a large amount of sound energy transmitted to the other side to form a sound insulation of trough, this phenomenon is called masking effect consistent effect: the presence of the masking effect of the human ear, when a voice higher than 10dB when another voice, the voice of small and difficult to be heard by masking and understanding, due to the masking effect, 90 -100dB environment, even at close range will not hear the speech. 2, ground partly because now most of the audience seats close to the body using sound absorption properties of soft cloth seats, so the audience hall reverberation time permits empty field detection . Sound absorption coefficient of the audience seating area, each seat absorption coefficient and some designers are given in accordance with the manufacturer's seat reference calculation; Another is the auditorium seating area designated as a high absorption coefficient to be calculated. , For more product information or to sample phase block, please call: 15913137176, 02066291993 Lei, business QQ: 81482540, I plant will provide free information to you with the reference model. Other parts of the ground are generally plastic flooring and carpet, which would be to determine the absorption coefficient depending on the circumstances. If you want to consider buying carpet thickness, material, whether lining and plastic; whether plastic floor seating area has been calculated according to seating area along with a range of sound absorption coefficient. 3, the absorption coefficient of the ceiling portion of the ceiling to be determined in accordance with sound absorption performance and environmental space decorative materials, and some ceiling using general decorative materials, such as paper, gypsum board, etc.; some use of mineral wool acoustic material; there Use mineral wool board and other materials cross the ceiling. The material itself is not the same absorption properties, ceiling position is different, and some because of the height of the ceiling space, close to the beam bottom lifting; some upper ceiling there is a certain degree of space, etc., which will also affect the specific reasons sound absorption performance. So, this is to be determined according to the specific circumstances of the absorption coefficient. , For more product information or to sample phase block, please call: 15913137176, 02066291993 Lei, business QQ: 81482540, I plant will provide free information to you with the reference model. In short, due to different site conditions, a variety of materials in the site-specific quantitative data to use in case of the absorption coefficient can be determined generally do not apply. Designers must accumulate experience, familiar sound absorption properties of different materials under different use of the environment, according to the scene to determine the absorption coefficient of each surface material selection. This will have a direct relationship to the audience hall also sound quality. If you want to ask which of acoustic materials, low prices and costs Which, of which plant size and service gives you satisfaction, it brought us Sam, your side of the acoustic manufacturers, for your listening escort Guiyang sound-absorbing soft bag manufacturer
