Noise Control Comprehensive Catalog - Sound Absorption Materials for Noise Reduction Product Group

Noise control measures aim for 'zero' sound stress by using lightweight plastic sheets as simple soundproofing materials to reduce 'machine noise' and 'echo noise'.

■Noise is one type of pollution. Noise has a negative impact on people. It can cause stress and prolonged exposure can lead to the risk of hearing loss. Therefore, measures against noise are necessary. ■What are noise control measures? We prevent sound waves from being transmitted. Specifically, we cover with perforated boards that absorb sound waves, or with thick, heavy materials like concrete, steel plates, or lead-lined curtains that are difficult for sound waves to transmit. However, it can be challenging to apply these to existing machinery or equipment. ■Simple soundproofing material utilizing the advantages of lightweight plastic sheet "Plaparl" With Plaparl, it is lightweight and can be processed into sizes according to the application. We offer a diverse lineup including boxes to cover small machinery, booths to enclose large machinery, panels to attach to walls, and partitions to divide spaces. ■Why does sound decrease with sound-absorbing materials? Sound, which is a vibration of air, is energy in wave form. Sound-absorbing materials absorb sound by converting "wave energy" into "thermal energy." Although it is heat, it does not become noticeably hot to the touch. There are mainly two methods to convert it into heat. *For more details, please refer to the catalog or feel free to contact us.*

  • NEW
  • PRODUCT

In recent years, with the outbreak of infectious diseases, there has been a demand for products that cater to "contactless operation," and this trend has extended to environments where automatic doors were previously operated by touch switches. As the automation of doors and the non-contact operation of automatic doors become more widespread, do you have any of the following concerns? ☑ Although automatic doors have been installed, they remain open due to people crossing frequently in busy areas. ☑ Touch switches have been introduced to reduce unnecessary openings and closings, but hygiene is a concern. ☑ Touch switches require regular battery replacements since they are powered. The light beam touch sensor "HA-T401" opens and closes automatic doors without contact, and its compact detection range makes it suitable for narrow passages and busy areas, contributing to energy savings and infection control. 【Benefits of Implementation】 ○ Adaptable to various door types with four spot settings, ideal for busy roads and narrow passages. ○ Energy-saving effects with two setting modes that reduce unnecessary openings and closings of automatic doors. ○ Equipped with a light beam touch function, allowing doors to open and close simply by waving a hand, ensuring hygiene. ◎ For more details, please download the catalog or contact us.
