Throughout the R&D, testing and quality inspection processes of complete vehicles, new energy powertrain systems, consumer electronics and communication devices, a test environment that conforms to actual working conditions lays a solid foundation for evaluating product NVH performance and acoustic characteristics. As a mainstream overall solution for acoustic laboratories, semi-anechoic chamber solutions adopt proven semi-anechoic chamber design to create a semi-free sound field. The walls and ceiling are fully installed with sound absorption structures, while the floor adopts rigid reflective design. Such facilities combine high load-bearing capacity and low-reflection acoustic performance, and are widely adopted by manufacturers of automobiles and new energy products, as well as R&D enterprises of consumer electronics and communication equipment. They are also included in laboratory planning by regional acoustic research institutes. Customized semi-anechoic chamber solutions can be adjusted flexibly according to site size, product specifications and test standards, delivering various forms including professional semi-anechoic rooms and semi-anechoic booths. They have become the preferred acoustic engineering solutions for automotive industrial parks and intelligent manufacturing bases across Southeast Asia.

When building NVH laboratories, automotive and new energy manufacturers generally cooperate with acoustic solution providers to implement integrated semi-anechoic chamber solutions. Designed based on the long-term application experience of automotive semi-anechoic chambers, these test spaces can simulate the sound reflection of road surfaces during vehicle operation, suitable for noise and vibration tests of complete vehicles, power batteries, drive motors and electronic control systems. During tests, acoustic measuring instruments, vibration measuring instruments and abnormal noise detection systems operate stably to measure sound power, abnormal noise, vibration and other indicators. For large commercial vehicles and complete new energy power modules, heavy-duty semi-anechoic booths are the ideal choice. A large number of Guangdong-based semi-anechoic chamber projects have been verified by the market for years. Their design concepts and construction standards are widely applied in automotive component factories and new energy laboratories in Singapore, Malaysia, Vietnam and other Southeast Asian countries. Different from full anechoic chambers which adopt sound absorption structures on all six surfaces, semi-anechoic chambers are more suitable for working condition tests of large industrial equipment. Combined with reverberation rooms, sound insulation chambers and quiet rooms, they can form fully functional comprehensive acoustic laboratories and expand the testing capacity of building acoustic measurement systems.

For R&D enterprises of consumer electronics and communication equipment, semi-anechoic chamber solutions can adjust spatial dimensions and internal layouts according to product types such as earphones, speakers, smartphones and communication base station devices. Standard semi-anechoic rooms are used to test sound quality, microphone sound pickup and active noise reduction performance of small and medium-sized electroacoustic products. High-power communication equipment and large terminal complete machines are placed in heavy-duty semi-anechoic chambers for long-duration working condition tests. Modular semi-anechoic units can be embedded into production lines for final inspection, isolating workshop background noise and supporting product sampling inspection. With concentrated electronics manufacturing clusters in Southeast Asia, local manufacturers widely adopt modular semi-anechoic chamber solutions to balance testing requirements and production efficiency, in compliance with international acoustic standards of IEC and ISO.

In terms of solution selection, full anechoic chambers are mainly used for calibration of small components and testing instruments, while semi-anechoic chambers and hemi-anechoic chambers with rigid floors focus on simulating actual working conditions for large industrial products and complete machines. The two types of facilities complement each other with no difference in performance level. Enterprises may select suitable semi-anechoic chamber solutions based on core products, test items and site conditions. Currently, the global automotive industry is transforming towards new energy vehicles, consumer electronics and communication products are updated rapidly, and the intelligent manufacturing industry in Singapore and Southeast Asia keeps expanding. The market demand for semi-anechoic chamber solutions and supporting acoustic engineering that comply with international acoustic standards maintains steady growth.
