From 1998 to 2026, Landtop Technology has cultivated the acoustics and vibration sector for 28 years. Adhering to independent innovation, we have obtained numerous national invention patents, utility model patents and software copyrights.
■ Core Invention Patents & Intelligent Algorithms:
→ Speech Evaluation Model Patent: Integrating auditory perception characteristics, it delivers high-precision evaluation models for speech quality, intelligibility and objective sound quality, empowering voice interaction in smart cabins and intelligent wearable devices.
→ Spatial Sound Field Reconstruction Patent: Holding the core invention patent of "Method and System for Spatial Sound Field Reconstruction", it achieves high-accuracy sound field reconstruction and multi-dimensional analysis.
■ Various Utility Model Patents:
→ We have been granted multiple national utility model patents covering innovative acoustic materials, high sound insulation/absorption structural components, automatic production-line test fixtures, and improved structures of high-precision sensors. These patents ensure superior stability and anti-interference performance of equipment in complex industrial environments.
■ Self-developed Software Copyrights:
→ We own full software copyrights for the ATOM Noise and Vibration Test System and the AaSQ Advanced Speech Quality Test & Analysis System.
1998
Official Establishment of Beijing Company
Officially registered and established in Beijing, we have been deeply engaged in acoustics and vibration. We are one of China’s earliest service providers committed to the industrial application of comprehensive acoustic and vibration technologies across industries.
2002
BCA Anechoic Chamber Construction & Application
The vehicle Pass-by semi-anechoic chamber and engine semi-anechoic chamber adopting the BCA composite resonant sound-absorbing structure were constructed and put into operation at FAW Group in China.
2009
ATOM Innovation Launch
The self-developed ATOM Acoustics and Vibration Test Data Management System has been commercially rolled out for the industry, focusing on the efficient management of automotive performance test data.
2016
Engineering Consulting Officially Launched
2019
The Chongqing Acoustics R&D Base was fully put into operation, and the AaSQ software was launched to the market.
● The acoustics R&D base in Chongqing has been fully completed and put into operation. It is equipped with mainstream laboratories required for acoustics and vibration development, including a 4-wheel-drive chassis dynamometer semi-anechoic chamber for complete vehicles, a 4-post environmental chamber semi-anechoic chamber, a vehicle modal semi-anechoic chamber and a reverberation room. Supported by a professional R&D team, the base enables full-range acoustic development and validation.
● The self-developed AaSQ speech quality test and analysis software was officially launched, breaking the monopoly of imported software.
2021
Completion and Production Launch of Beijing Acoustic Structure Manufacturing Base
It undertakes the R&D and manufacturing of core acoustic products and structural components. Leveraging multiple utility model patents for acoustic structures, it realizes high-precision in-house production of anechoic chamber components as well as sound and vibration isolation materials.
Chongqing · R&D Base
Located in the central and western manufacturing and automotive hub, the base integrates data acquisition, product verification, engineering consulting and technical training. It converts self-developed patented technologies into responsive, high-precision third-party acoustic and vibration testing and consulting services.
Beijing · Production Base
It undertakes the R&D and manufacturing of core acoustic products and structural components. Supported by a number of utility model patents for acoustic structures, it realizes independent and high-precision production of anechoic chamber components as well as sound and vibration isolation materials.
Our R&D and production processes are implemented in strict accordance with international standards, and we have fully obtained the following certifications:
Adhering to high-standard quality control, green production and safe operation, we ensure that all delivered projects and equipment feature reliable performance and long-term stable operation.
Landtech focuses on the R&D and application of acoustics and vibration technologies, providing a full range of comprehensive solutions including professional acoustic testing hardware and software instruments, forward-looking test scheme development, acoustic and vibration R&D and technical consulting, as well as the planning, design and construction of acoustic laboratories.
