【Mobile China News】On July 13, jointly initiated by the China Electronic Audio Industry Association and the China Electronic Technology Standardization Institute, T/CAIACN 008-2022 "Hd Wireless Audio Technology and Equipment Specifications and Test Methods" was officially released (hereinafter referred to as HWA HD Wireless Audio Standard, Hi-Res Wireless Audio, Standard), which triggered a hot discussion on the whole network for a time. The next day, HWA's first authorized laboratory license and laboratory open day was also successfully held in the China Electronics Technology Standardization Institute, and many industry leaders witnessed a new milestone in the high-definition wireless audio industry.
Chen Lixin, executive vice president of the China Audio Association, said that the mainland already has the world's largest audio manufacturing industry chain and the largest audio consumer market, and plays an important role in the global audio industry chain. Since 2018, the Chinese Music Association has joined hands with more than 30 backbone enterprises in the industry such as Sennheiser, Goertek, Huawei, Guoguang, And Wanderer to carry out joint research, after technical solution research, evaluation technology development, test environment construction and instrumentation development and other research and development, after many public discussions and expert reviews, through 5 years, finally open up the whole process from technology research and development, standard formulation, evaluation specifications, test evaluation, and finally bring more sound quality, more stable connection, Lower power consumption HWA HD wireless audio standard licensed products.
HWA HD wireless audio standard is a comprehensive standard based on consumer actual experience as the starting point, covering subjective and objective evaluation, based on the end-to-end standard architecture, from "technology + experience" to "experience as the core + technology openness", forming a more open and inclusive industrial ecology. The official release of the standard also marks that the mainland wireless audio industry has reached the world's leading level in technical research, product design, quality evaluation and other fields. The standard not only integrates the objective test of electroacoustic performance and subjective listening evaluation, but also increases the performance requirements for codecs, wireless transmission, delay, anti-interference, active noise reduction, transmission, and battery life.
As the first authorized laboratory in HWA, Saixi Laboratory will also give full play to the advantages of professional foundation in the field of standard testing and provide more objective, professional and authoritative testing and evaluation services for the industry. In view of the requirements of HWA HD wireless audio standards, Saixi Laboratory upgrades the existing test environment and equipment capabilities, relying on audio labs, network laboratories, and subjective audio-visual rooms, forming a test verification capability covering all technical indicators of HWA HD wireless audio standards.
The establishment of Saixi Lab and the promulgation of the HWA hd wireless audio standard will promote the structural optimization and upgrading of the mainland audio industry, and will also bring consumers a new audio product experience upgrade. A few days ago, Huawei has officially announced that the world's first TWS headset Huawei FreeBuds Pro 2 that has been certified by HWA will be released recently, so let's look forward to it together.
