KMI Acoustics delivers end-to-end acoustic solutions for creating precision-controlled silent labs (anechoic/semi-anechoic chambers) and on-demand quiet workspaces (soundproof pods, cabins). Leveraging patented Microcrystalline Damping Technology, NVH testing labs, and global EPC capabilities, we transform noise challenges into tailored environments of silence—from industrial R&D facilities to instant office pods. Partner with us to engineer certified quietness, anywhere.
KMI Acoustics – Global High-End Integrated Acoustic Solutions Provider
Founded in 1998, KMI Acoustics has been dedicated to the R&D and application of noise control and acoustic sound-absorption. It has now evolved into a high-end integrated acoustic solutions provider, offering comprehensive services encompassing R&D, design, manufacturing, construction, and after-sales support. We operate a 40,000 m² modern manufacturing base and a 3,600 m² dedicated acoustic R&D center. Our professional team of over 160 members includes more than 30% R&D and technical personnel. Our business network spans 36 countries and regions worldwide, having served over 2,000 industrial enterprises with reliable acoustic treatment solutions.
Leveraging our technological leap from “passive noise reduction” to “precision sound control,” we utilize our independently developed Microcrystalline Damping and Vibration Isolation Technology, a large-scale NVH semi-anechoic laboratory, high-precision acoustic simulation, material testing capabilities, and a joint venture production line for high-end anechoic facilities established with SONORA, a leading Japanese acoustic enterprise. We provide full-chain EPC services covering environmental impact assessment, solution design, intelligent product manufacturing, installation & construction, and after-sales support.
Our Core Acoustic Products & Solutions
1.Fully Anechoic Chamber Simulates a free-field acoustic environment with all six surfaces lined with high-performance absorbent wedges. Designed for high-precision acoustic measurements, electroacoustic product testing, acoustic research, and other applications requiring an absolute absence of reflected sound, compliant with international standards such as ISO 3745.

2.Semi-Anechoic Chamber Features a reflective floor with the other five surfaces lined with acoustic treatment, simulating a semi-free-field environment. Widely used for Noise, Vibration, and Harshness (NVH) testing, sound quality evaluation, and R&D verification in industries such as automotive, home appliance, and machinery.

3.Soundproof Chamber [Master Chamber] Incorporates a multi-layer composite sound insulation structure and is equipped with a ventilation silencer system. Designed to create an independent space with high sound insulation performance, suitable for equipment noise control within factory workshops, control rooms, audiometric test rooms, precision instrument rooms, and other environments requiring a high degree of quietness.

4.Anechoic Box [Master Cube] A compact, modular-designed anechoic testing device, easy to install and relocate. Ideal for rapid acoustic inspection of products at the end of production lines and for acoustic performance verification of small components like speakers, microphones, and sensors.

5.Soundproof Box [Master Box] A movable acoustic enclosure for individual noisy equipment, balancing sound insulation, ventilation, and operational maintenance needs. Commonly used for on-site noise control at the source for industrial equipment such as air compressors, fans, pumps, and generators.

6.Silence Pod A standalone, intelligent quiet space integrating sound absorption, insulation, and vibration damping technologies. Provides a plug-and-play serene environment for offices, study, meetings, medical testing, and more, flexibly meeting the modern demand for acoustic privacy in work and life.
