Sound Pressure Level Test Service

 
Sound pressure level (short for sound level) is the main testing item in acoustics field, the purpose of which is to test the magnitude emitted by products, and the unit is dB, or dB(A). Our company offers complete sound pressure test, and based on the testing result, we can give free consultation, and formal report accordance with TAF(iLAC Member).
 
Very Low Background Noise
 
According to ISO standards, if noise from EUT are on the same frequency level of the background noise, the test results can not actually be used to determine if the results are correct. However, most companies may accept such unqualified test results as standards, the results may be faulty. Our lab, can do better, as our lab is designed to provide a sound camber that can provide TRUE results with the highest quality sound test equipment.

Our equipment and lab cambers satisfies ISO7779, which translates to being able to simulate the real condition of each individual users. The labs should be a hemi-anechoic chamber. The background noise of our lab is only between 6-8 dB(A) tested by state-of the art equipment. Compared with other labs, measuring on an average at 20 dB(S), using us will give you a greater edge, and true results.
