Assembled Semi-anechoic Room

No. 1 share in domestic sales of assembled semi-anechoic rooms

Product Overview

Assembled semi-anechoic room is an anechoic space for noise measurement(acoustic power level measurement) of equipment and mechanical. Assembled by Sola metal panels and frame, the inner side consists of non-combustible sound absorbing wedge. It is possible for disassembling and relocated the subject since the assembled semi-anehoic room doesn’t use concrete walls. Besides, we can design customized products according to the purpose of measurement and the layout.

Measuring Targetprecise instrument, auto parts, electronic components, nanotechnology-related products, environment-related products, etc.
Measuring Purposeacoustic power level, acoustic intensity measurement, abnormal sound detection, acoustic measurement for product performance, etc.
Measuring Machinegeneral or precise noise meter , FFT analyzer, vibrometer, various acoustic evaluation equipment, etc.

About Lead Time

Usually, the lead time is about 60 days after order.

It is shortest around 60 days if it’s a standard product size. Please contact us as it may change depending on the operation of the factory. There are many anechoic room orders especially in the busy period. So the lead time of the large anechoic chamber which is over the standard size will be longer.

About Installation

Assembled Semi-anechoic RoomBecause of the prefabrication system, it is possible for a short-term construction on site.

The soundproof panel and frame of an assembled semi-anechoic chamber is manufactured in the factory site and will be assembled at the construction site. Unlike the traditional concrete or board construction, the small size can be manufactured in a few days and the large size can be done in 1 to 2 weeks.

※ we have many overseas export and assembly achievements.

Type/Price

The specifications are just for reference, customize from scratch.

There are 3 types of specifications for use. But basically, we’ll design from scratch according to the size, measurement method and workability of the user’s acoustic measurement object. We can meet all kinds of requests, such as installing a crane, flattening the bottom of the door so that there is no step when carrying in, controlling temperature and humidity in an anechoic room, and conducting a wind tunnel test.

Means

Top-class sound insulation performance is guaranteed.

The unrivaled sound insulation performance of an anechoic room that other companies can never compare.

The background noise in an anechoic room can even reach 0 dB depending on the installation environment. An advanced acoustic measurement space can be realized by introducing our anechoic chambers.

About Sound Insulation Performance

We 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”.
