sound absorption การใช้

• Sound absorption coefficients of common materials used in buildings are presented in this table.
• Finally, sound absorption can cause high frequencies to be rolled off, dulling the sound further.
• Top models also came with molded fiberglass acoustical headlining and sound absorption pads behind all interior panels.
• The acoustic performance of suspended ceilings has improved dramatically over the years, with enhanced sound absorption and attenuation.
• Tests show, depending on the application, the technology can improve sound absorption by 50 percent to 1, 000 percent.
• This material has been used extensively on the walls and ceilings inside the auditorium for its sound absorption qualities.
• They tested materials for qualities such as color, texture, structure, resistance to wear, flexibility, light refraction and sound absorption.
• The choice of materials like wood and concrete is based on cost, appearance or maintenance considerations rather than sound absorption.
• Although carpet is an obvious choice for sound absorption, it may not be suitable for high traffic areas like hallways.
• This type of sound absorption is different from soundproofing, which is typically used to keep sound from escaping or entering a room.
• And special care has been taken with sound absorption; there's even a noise-muffling white-noise system, although so far it hasn't been deemed necessary.
• The result is a heavier body than usual for kit cars, but one with reputedly greater stiffness and sound absorption than the single-layer approach.
• This difference is usually neglected, sometimes by explicitly assuming 0 } }, but it could have an impact in sound absorption and attenuation and shock waves.
• Melamine foam is the active component of a number of abrasive cleaner sponges, see bullet trains, due to its high sound absorption, excellent thermal insulation performance and light weight.
• Next fasten a sheet of 5 / 8-inch-thick wallboard onto the fiberboard; use construction adhesive for this because it is more resilient than screws or nails and will add another measure of sound absorption.
• On the basis of the sound absorption theory of Micro perforated plate proposed by Prof . Daa-You Maa, Danqun Fang successfully developed a series of micro-perforated plate mufflers, which was widely used for sound absorption.
• On the basis of the sound absorption theory of Micro perforated plate proposed by Prof . Daa-You Maa, Danqun Fang successfully developed a series of micro-perforated plate mufflers, which was widely used for sound absorption.
• The school moved to Dessau that year, and a new focus on production rather than craft at the Bauhaus prompted Albers to develop many functionally unique textiles combining properties of light reflection, sound absorption, durability, and minimized wrinkling and warping tendencies.
• "The sound absorption up those side walls, along the ceiling and down again along the back is almost complete, " said Jacobs, who last year won a technical Oscar for his part in developing a system to analyze movie theater projection.
• Production ballooned during World War II and afterwards, when asbestos was put into products that touched virtually everyone's daily life : insulation, fireproofing, sound absorption, roofing, siding, pipes, brake linings, gaskets, ships, floor tile, adhesives, plastics, fire-resistant fabrics-- and, most significant in today's litigation picture, drywall joint compound.
