The Significance of Our Acoustic Laboratory and Acoustic Instruments in the Home Appliance Industry 

In the home appliance industry, we focus on end products such as refrigerators, washing machines, air conditioners, and kitchen appliances like range hoods and dishwashers. We specialize in acoustic performance optimization and noise control for home appliances, with in-depth coverage of two core application scenarios: noise reduction for daily-use home appliances to create a quiet living environment, and acoustic experience enhancement for smart home appliances such as intelligent refrigerators and voice-controlled kitchen devices. 

Through the following three core technical approaches supported by our acoustic laboratory and advanced acoustic instruments, we can achieve a balance between product functionality and acoustic comfort, helping home appliance products gain competitive edges in the market: 

 - Precision noise source identification and analysis: Leveraging professional acoustic instruments like sound level meters, acoustic cameras, and vibration analyzers in our laboratory, we accurately identify noise sources of different home appliances (e.g., the compressor noise of refrigerators, the motor noise of washing machines, and the airflow noise of range hoods). We then conduct spectral analysis and vibration testing to provide a scientific basis for targeted noise reduction. 

- Customized acoustic package design: For different types of home appliances, we design customized acoustic packages using our laboratory's simulation and testing capabilities. For example, we develop sound-absorbing cotton with specific density and thickness for refrigerators, design vibration-damping mounts for washing machine motors, and create airflow-optimized duct structures for range hoods. These designs effectively reduce noise transmission and radiation. 

- Comprehensive acoustic performance testing and certification: Our acoustic laboratory is equipped with semi-anechoic chambers and full-anechoic chambers, enabling us to conduct comprehensive acoustic performance testing for home appliances, including sound pressure level testing, sound power level testing, and sound quality evaluation. We can also help enterprises meet international and domestic acoustic standards and certifications, ensuring that products meet market access requirements and user expectations for low-noise products. 

In addition, our acoustic solutions can address the acoustic needs of home appliances in an important application area:  

- High-end home appliance segment: Concentrate on improving the acoustic quality of products to meet the demands of high-end users, such as achieving ultra-low noise operation of luxury refrigerators, creating quiet and comfortable operating sounds of high-end dishwashers, and ensuring the airflow noise of premium range hoods is below the threshold of human perception. Ultimately, with the support of our acoustic laboratory and acoustic instruments, we aim to create a quiet, comfortable, and high-quality acoustic environment for users in their home life, covering daily household chores, smart home interactions, and high-end living experiences.
