For the production line of refrigerator compressors, Microline proposes the product noise control. The test is based on the use of accelerometers, up to three, positioned in strategic points of the compressor. The analysis involves the calculation of the Fourier transform of the acquired values and the successive subdivision into “narrow bands” that can be easily set. An assessment criterion is applicable for each band.
This test can be dedicated to other product types, besides the compressor.
