Factory
Mt. Fuji Technology Center “Gotemba, Shizuoka Prefecture” owns the best equipment in the sound insulation manufacturing industry. (Introducing turret punch press, press brake, solid works, etc.) This equipment is completely different from our manufacturing method so far, and it can handle complicated designs, realize high ideas and respond to short lead times. Besides the development of manufacturing level, we can provide high-quality products at a low price with the development of automation, assembly line, and the significant reduction in manual processing cost.
Showroom
“The showroom is currently under renovation. The opening time is scheduled for November 2020 after renovation. There is a showroom for anechoic rooms and soundproof rooms in Mt. Fuji Technology Center. Please verify the high performance of our products in the actual use of the measuring instrument.
Meanwhile, please experience the special anechoic space practically. In addition to the showroom, we also offer videos introducing our company and visits of the factory. There are almost no institution that open anechoic chamber for free in Japan. It can also be used outside of business, such as those who are considering purchasing our products, those who are interested in us, the general public and the media. Please come by all means.
※ However, the reservation system require contact in advance and registration for the purpose of use. Depending on the purpose, there are occasions where you may not be able to use it.
Business Concept
5 Weapons of Sonora
When anechoic rooms or soundproof rooms are imported, surveys are carried out on the client’s requirements of the manufacturers, it shows that “low price”, “quality”, “development capabilities”, “speed”, “certainty”, “credibility”, “coping capacity” are relatively prominent.
At Sonora Technology, we can meet the clients’ needs with our “5 Weapons”. Here, we will explain the competitive advantages over other companies in the industry.
1. Manufacturing with the newest equipment
In January 2009, the company invested more than 200 million yen in equipment, introduced the latest turret punch press, press brake, solid works, etc. And established digital sheet metal factory in Gotemba, Shizuoka.
This equipment is completely different from our manufacturing method so far, and can handle complicated designs, realize high ideas and respond to short lead times.
Besides the development of manufacturing level, we can provide high-quality products at a low price with the development of automation, assembly line, and the significant reduction in processing cost by human hands.
2. Professional Technology
Our company has unique noise control technologies such as multi-layer sound insulation METAL panel, ultra-low frequency sound insulation method, AS sound absorption wedge, sound insulation measurement method considering the spatial difference before and after installation of equipment.
This is the know-how accumulated from the experiences of failure and and success based on a large number of sales achievements.
But, unlike residential sound insulation, building sound insulation and public works, we specialize in industrial noise control which require a high level, we are constantly improving our expertise although it’s narrow.
Unique technologies for noise control
- multi-layer sound insulation METAL panel
- ultra-low frequency sound insulation method
- AS sound absorption wedge
- sound insulation measurement method
3. Probative force
First, numerical proof
We guarantee and verify the acoustic performance for all products, and submit the data together as a report
Second, confirmation of the real objects
We have established a showroom for anechoic chambers, anechoic boxes and soundproof rooms in the same area as the sheet metal factory mentioned before. In the discussion stage, clients can do simulation test through the sample machine, and the products can be judged through the user’s eyes.
Third, Proofs
There are a number of sale achievements in many major private enterprises.

4. Organization and operation by a small number of elite
We are not a subdivided organization like large enterprises. However, with minority operation, we have extensive knowledge, the speed of decision making, pace, and individual business frameworks that go beyond theirs.
As mentioned earlier, non-manual systematic sheet metal work doesn’t require human labour.
Furthermore, in terms of construction, unlike construction works in which walls and ceilings are made on-site from scratch, the panels manufactured at the factory can be assembled on installation site without the labor costs of equipment installation operations. Because of the small number of people, it is possible to provide low-price services to users.
5. Constant evolution/ sharing of development capabilities
We hold the point that the construction of anechoic rooms and soundproof rooms is part of the co-development related to user product development. Therefore, we need to constantly evolve to cater to the evolution of our users, rather than propose outdated products. We conduct “on-site development” at our own factory, “theoretical development” by technicians and industry-university cooperation to create new solutions.
Moreover, we have anechoic chambers and sound insulation measuring devices, etc., which are helpful for research and development. Differences in technological capabilities from other companies are also come from differences in research equipment.
