Assembled Anechoic Room

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

Product Overview

The assembled anechoic room consists 6 surfaces, using Sola metal panels and absorbing wedges on the wall, ceiling, floor. The regular anechoic room uses concrete, plaster board, special cloth type sound-absorbing wedge. But our anechoic room has the advantage of assembly, low price, high accuracy and relocation. In addition, the new developed X type can achieve the best effect in the smallest space.

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

The soundproof panel and frame of an assembled anechoic room are 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.

The specifications are just for reference, customize from scratch.

There are 3 types of specifications. 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.

Top-class sound insulation performance is guaranteed.

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

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”.
