Product Overview

Anechoic box is a small acoustic box which have the feature of high sound insulation( transmission loss) and sound absorption. It’s applied to measuring the noise of a product, inspecting the abnormal sound, quality control, research and development.

Utilizing our noise control technology, we developed special multi-layer panel. Over the past 9 years, we have proposed, designed and manufactured over 300 units according to a wide various using purposes and specifications. The high sound insulation performance with guarantee performance is unrivaled compared with other companies.

Measuring Target	communication information equipment, Precise instrument electronic components, nanotechnology-related products, environment-related products.
Measuring Purpose	abnormal sound detection, research and development, acoustic measurement for product performance, vibration analysis, environment test, etc.
Measuring Machine	general, precise noise meter, FFT analyzer, vibrometer, various acoustic evaluation equipment, etc.

※ Anehoic box is using R&D measurement. And optimized according to user’s measuring method and specifications.

About Lead Time

Usually, the lead time is about 30 days after order.

It may change depending on the operation of the factory, so negotiated with us by any chance. In addition, the manufacturing period will be longer than the lead time when an anechoic box door is applied to an electric situation or as an option of coupling specification, etc.

About Installation

Our installation works are not necessary.

Basically, transportation methods are: crane truck unloading, truck transportation without unloading. Since the anechoic box is equipped with casters, it can be manually moved to the installation location. We will check the transportation route, the load of the elevator, steps and maintenance since the anechoic room is heavy. And we can also undertake transportation, delivery and installation.

※ Can be exported to overseas.

Type/ Price

Anechoic boxes are available in TYPE 1 to TYPE4 specifications. But basically, we’ll design according to the size of the user’s measuring subjects, measurement method and workability. There are many examples such as using the drive mode (electric, pneumatic, hydraulic) to open and close the door, addition of lighting and BNC socket, and the setting position of microphone adopts free configuration.

Specification

Sound Insulation (Transmission Loss) / dB

Top-class sound insulation performance is guaranteed.

The sound insulation performance of an anechoic box is unrivaled comparing with other companies. The background noise in an anechoic box can even close to 0 dB depending on the installation environment. An advanced acoustic measurement space can be realized by introducing our anechoic boxes.

About Sound Insulation Performance

We can guarantee the sound insulation performance by using a noise signal generator, speaker, general noise meter or precise noise meter, measuring (transmission loss test) according to JISA1417:2000. And submit the test result as a “Measurement Result Report”.
