Abstract. It is a common problem in detector physics that reducing noise of one type introduces noise from another source, lowering the practical sensitivity of detector instruments. This investigation is an analysis of vibrational noise from around a pulsetube-cooled dilution refrigerator (DR) intended to test instruments for particle dark matter and rare event searches. Analysis of the frequencies of vibrational noise near the DR finds that the active vibrational damping used in the lab lowers the noise by more than 87.36% in the frequency band between 6 and 19 Hz, which is where the cooling system contributes the most significant mechanical noise.
