Recently, the internationally renowned research organization Eastern Management Group released a report, and Yealink became one of the brands with the highest customer satisfaction among the surveyed companies. After surveying thousands of IT decision-makers, 99% of Yealink’s customers said they would recommend Yealink’s products to their friends. The ultra-high Net Promoter Score (NPS) not only reflects strong customer loyalty, but also shows that the products and services bring customers the almost ultimate experience.
Creating quality products is the product philosophy of Yealink Networks. "The edge of the sword comes from the sharpening." The birth of the high-quality goods stems from the hard work. The secret behind the international product quality is Yealink’s continuous investment in product polishing. More than 50% of the company’s employees are engaged in technology research and development and invested heavily in the construction of national laboratories to jointly support Yealink’s efforts to overcome many technical problems. It has developed industry-leading underlying audio and video technologies, and obtained honorary certifications such as "National Intellectual Property Advantage Enterprise" and "National High-tech Enterprise".
A few days ago, Yealink Networks has added a "new member" to its national professional laboratory-the adjustable reverberation laboratory. It provides a strong guarantee for the sound quality improvement of Yealink's network video conferencing and voice communication products, and the R&D strength is raised to a higher level.
Adjustable reverberation room: "hardened" sound quality is upgraded
The half-meter-thick gate, crisscross diffusers, layers of soundproofing materials, mufflers with different angles... all together form this technologically-sense space-the adjustable reverberation laboratory.

It is reported that the adjustable reverberation laboratory is a professional acoustic laboratory. Through special materials and design, it can control the reverberation time of indoor sound, and form an environment with uniform energy density through the reflection of sound energy.
The biggest advantage of this is that it can simulate various conference room scenes indoors by controlling the reverberation time of the sound, and provide the audio and video products developed by Yealink Networks with a sound detection environment that meets or exceeds international standards, and truly reflects the product. Various sound quality indicators for targeted tuning.

In addition, the size of the laboratory volume determines the range of acoustic environment that the reverberation room can simulate. The adjustable reverberation laboratory built by Yealink is one of the largest laboratories in the industry and has excellent performance indicators.
Different from the audio laboratory (anechoic chamber) that provides a very quiet detection environment, the new adjustable reverberation laboratory complements each other in function, creating good conditions for repeated "hardening" of product sound quality.
Overcome every sound difficulty and pursue the ultimate sound effect
The knowledge of sound is more than simply listening and speaking on audio and video equipment. The resonance of the device cavity, the transmission of sound signals, the restoration of sound details... To create a good sound quality experience for users, the "battle" starts from the first second of a call.
In the process of sound transmission, Yealink has established a dedicated team to overcome every sound problem, including pickup, packet loss, noise reduction, reverberation, echo, connection, and playback.
Voice transmission characteristics
Currently, the audio and video equipment launched by Yealink Networks has been equipped with multi-microphone array technology for sound pickup, intelligent noise cancellation technology for noise cancellation, and self-developed codec technology for anti-packet loss. A variety of leading technologies such as adaptive equalizer technology for sound reproduction and multi-array microphone cascade technology for connection. The sound quality level has passed the Microsoft Teams certification, which is the most stringent industry standard, and has become one of the few certified manufacturers in the world.
Continuous R&D investment: enhance the core competitiveness of the company
Yealink has not only made great efforts in audio, but also invested a lot of resources and manpower in breakthroughs in product performance. Yealink Networks is an enterprise with a strong engineer culture, focusing on product research and development. Now it has developed into one of the few domestic R&D enterprises that can compete with foreign counterparts in the unified communications field.
Long-term focus on the corporate communications market has allowed Yealink to accumulate strong audio and video underlying technologies. Yealink Video System has obtained the industry's first Tyre 5-star safety certification, and has been selected as a "National Intellectual Property Advantage Enterprise", and its professional technical strength has been certified by various authoritative organizations.

In the industry, there are very few companies that have the strength to invest huge amounts of money to build professional laboratories. Up to now, Yealink has spent tens of millions to build a series of professional laboratories such as EMC laboratories and audio laboratories.
