分貝(dB)

0000-00-00

人們在日常生活中,無時無刻都能感覺到聲音的存在。
聲音的產生是由於物體的振動(音源)引起周圍空氣分子的震盪,使聲波經由一個空氣分子傳送到另一個空氣分子,這樣的波動透過空氣為傳遞介質向外傳播,當波動能量傳遞到耳朵後,經由耳鼓膜振動傳遞到聽覺神經讓我們感受到聲音。

而分貝則是用來表示聲音強度的單位,記為dB。

噪音污染已經成為社會突顯問題,根據調查,噪音量每提升一分貝,高血壓發病率就增加3%,影響人的神經系統,使人急躁、易怒 ;臥房音量偏高亦會影響睡眠,令人難以入睡,偶發且過大的噪音可以令人在睡眠中醒來,從而擾亂睡眠,造成睡眠不足或感到疲倦。40~50分貝的聲音會干擾睡眠,60~70分貝會干擾學習,120分貝以上的噪音量會導致耳痛,甚至聽力永久喪失。
一般而言,NC 值加10 大概與dB(A)值相同,而NR 值加5 大致與dB(A)值相同


Application


  • Curve Ceiling System

    Curved line represents perfectness. Through rhythmic curved modeling, a comfortable and graceful style is created. Combined with the first and last quarter curves, it turns out continuous wave lines to perfectly extend curves metal ceiling.

  • Triangular Ceiling System

    The creativity of circle, square and triangle is from the most original elements. Through clever use of simple, rational and orderly geometric patterns, you’ll have peaceful, gentle and latest technological feeling. Centered by octagon connector and radially extended by triangular flat or cell metal ceiling or with flat, solid or hollow engraved design, a unique and modern art image was emerged.

  • Linear Grid System

    Perfection is the pursuit of interior designers. Linear Grid System can combine with different types of ceiling panels to create artistic ceiling system. Whether pyramid-shaped, three-dimensional art style, or simple style ceiling panels, it all can create your own unique ceiling space.

  • Baffle System

    A simple space with infinite imagination. Through flat or strip panel in solid or horizontal arrangement, a new visual impression was created with not only beautiful lines but also imagination of infinite extension. Its feature of flexible arrangement and assembly makes it has the best visual effect.

  • Crossing Ceiling System

    Connected by tapered shape with a cross modeling at joint, it is the most stylish and creative metal ceiling with implication of success and luck. Using this creativity of full of cross at wide surface, quality and avant-garde living space were highlighted.

  • SoundMicro Micro-perforated Acoustical Panel

    Intrigued from theory by Ma, Da-You in 1970s, many countries have involved for noise control to replace harmful material such as mineral wool and glass wool. Since 2001, we have cooperated with NSC and NCKU to research its acoustic absorption and developed broadband board with aperture up to 0.1mm far lower than 0.5mm of others and absorption ratio of NRC 0.7-0.9 within 0.8 of αω value by ROC.

  • Groove Partition

    CKM groove partition is produced on full automatic production lines, the specification of punching and length are strictly controlled by computer, thus we can produce normalized products with great efficiency and accuracy. It is suitatble for channel and elevator walls of various kinds of buildings.

  • Regular Type Partition

    Regular type partition is produced on full automatic production lines, the specification of punching and length are strictly controlled by computer, thus we can produce normalized products with great efficiency and accuracy. The board material can be metal or plaster, and the partition can be made fast and beautiful by collocating with putty, painting or wallpaper.

  • Groove Partition-test

    CKM groove partition is produced on full automatic production lines, the specification of punching and length are strictly controlled by computer, thus we can produce normalized products with great efficiency and accuracy. It is suitatble for channel and elevator walls of various kinds of buildings.

  • Lay-in Cell Ceiling

    In additional to the infinite extension effect, its combination of small cells can meet the design demand of sense and sensibility.

  • Concealed Cell Ceiling

    In additional to the infinite extension effect, its combination of small cells can meet the design demand of sense and sensibility.
