We received a request for noise control measures for the air conditioning equipment in the warehouse office located in the Tokyo metropolitan area, and we have addressed it. It seems that many logistics facilities, including warehouses, are transitioning to operations from early morning to late at night, or even to a 24-hour system, leading to an increase in the operation of air conditioning units during early morning and late-night hours. To ensure that maintenance of the machinery is not hindered, we installed a door at the front. The soundproofing effect is a reduction of 15dB. 【Overview】 ■ Construction Date: October 2018 ■ Purpose: Soundproofing of cooling towers for power transmission and transformation equipment ■ Objective: Reduction of noise generated during equipment operation ■ Soundproofing Effect: 15dB reduction ■ Region: Metropolitan area *For more details, please refer to the PDF document or feel free to contact us.

• Soundproofing/Shielding Unit

We would like to introduce a case of noise control measures for high-voltage substation equipment at a plastic parts manufacturing factory located in Gifu Prefecture. High-voltage substation equipment used in factories generates a certain level of "hum" and "vibration." Although it is not as loud as the operating noise of engines or generators, it still requires consideration for nearby residents during late-night hours, which is why we received this request. As a countermeasure, we installed a soundproof wall measuring approximately 13 meters wide and 3 meters high to prevent sound from leaking outside. We achieved a soundproofing effect of 7dB. 【Overview】 ■ Construction Date: January 2019 ■ Purpose: Soundproofing for a plastic parts factory ■ Soundproofing Effect: 7dB reduction ■ Location: Gifu Prefecture *For more details, please refer to the PDF document or feel free to contact us.

• Soundproofing/Shielding Unit

Here is an example of noise reduction measures taken for solar power inverter systems. More companies are shifting a portion of their power consumption to solar energy, and a common concern is the high-frequency noise generated by the power conditioners. While it is not particularly loud, many people find it unpleasant. We received a request from such a company and took action. By firmly guarding the soundproof wall with soundproof sheets, sound-absorbing materials, and steel plates, we anticipate a noise reduction effect of about 10dB. 【Overview】 ■ Construction Date: March 2019 ■ Purpose: Noise reduction measures for solar power inverters ■ Aim: Soundproofing against high-frequency noise generated by machinery ■ Noise Reduction Effect: Approximately 10dB ■ Region: Tohoku Region *For more details, please refer to the PDF document or feel free to contact us.

• Soundproofing/Shielding Unit

We would like to introduce a case study of a "Precision Machinery Enclosure" designed to eliminate air vibrations caused by external sounds to the utmost extent when precision machinery is in operation. Since this is a customized solution tailored to the customer's needs, we conduct thorough discussions, design, prototyping, and testing from the development stage before manufacturing. The request from the user of the enclosure we are introducing this time was to reduce the sound in the 125Hz range by 20%. After numerous tests and trial and error, we provided a confident product from Sun-O. 【Overview】 ■ Construction Date: August 2019 ■ Purpose: Soundproofing for precision machinery ■ Soundproofing Effect: In this case, a 20dB reduction in the 125Hz range ■ Estimate: To be discussed *For more details, please refer to the PDF document or feel free to contact us.

• Soundproofing/Shielding Unit

We received a request from a certain school for soundproofing measures for the operating noise of an air-cooled heat pump chiller, and we responded accordingly. We installed a soundproof wall in a U-shape around the target equipment to reduce its operating noise, with dimensions of approximately 7.5m x 5.5m x 3.6mH. The wall is made of durable Galvalume steel, making it suitable for outdoor use. Additionally, the soundproofing effect varies greatly depending on where the wall is installed, so we conduct noise measurements in advance and provide an optimal soundproofing plan. 【Overview】 ■ Construction Date: October 2019 ■ Purpose: Attenuation of noise from the air-cooled heat pump chiller ■ Performance/Request: -10dB attenuation effect ■ Location: Tokyo *For more details, please refer to the PDF document or feel free to contact us.
