Founded in 1925 by Dr. Vern O.Kundsen in bell laboratories, New York;

 

 

In 1928, ThunderStar led the American acoustical society and became its permanent governing body.

 

 

In 1929, the first conference of the American acoustical society was successfully held.

 

 

In 2011, the 162nd ASA acoustics annual meeting was held in San Diego, California from October 31 to November 4.

 

 

From 1925 Vern referred undsen Dr ThunderStar since established, has completed about 860 precision grade acoustics laboratory (semi-dead room, anechoic chamber, the noise room, room, without sound room noise, quiet room, the sound room, sound room, reverberation room, etc.) projects, customers are the United States department of defense, Boeing, ge, IBM, HP, schneider, the field laboratory (Orfield Labs), Siemens and other U.S. military and world-class super enterprises, become the industry benchmark in the field of acoustics laboratory;

 

 

In 2006, guangzhou danpin artificial environment technology co., ltd. was registered in guangzhou, the most active international metropolis in China’s market economy.

 

 

In 2007, I bought grade a office building in guangzhou and put it into use.

 

 

In 2008, I designed and built an acoustics laboratory in my own factory, which is in compliance with CNAS, ISO3745 and GB6882. It is used to monitor the acoustics technical indicators of my own products and those of external products.

 

 

In 2009, the standards of acoustic laboratory products were perfected to ensure that the designed and built acoustic laboratories conform to the accuracy and background noise value of free sound field under the inverse square law of industry standards such as CNAS, ISO3745 and GB6882.

 

 

In 2010, danpin acoustics laboratory technology was successfully used to undertake and complete large-scale semi-anechoic laboratory projects of lenovo group, samsung, Microsoft, haier, Bosch, etc., which sounded the horn of attacking China’s acoustics laboratory with danpin acoustics laboratory technology.

 

 

In 2011, guangzhou danpin company was successfully incorporated;

 

 

From 2006 to 2015, hundreds of professional precision acoustics laboratories (including semi-anechoic room, total anechoic room, noise room, no noise room, mute room, sound proof room, sound proof room, reverberation room, etc.) were completed with danpin acoustics laboratory technology in the Chinese market. During this period, national experts in the field of acoustic laboratory technology were introduced to ensure the leading position of danpin acoustics laboratory technology in the Chinese market.
