A global provider of information technology services and equipment selected Sound Answers to address the sources of noise and identify countermeasures for overall noise reduction of their paycheck sorter unit. Both operating and stationary measurements were made in a fully anechoic chamber. Near field acoustic holography measurements were made in conjunction with narrowband, 1/3 octave band, and FRF analysis to troubleshoot all relevant noise sources. Countermeasures to address resonance issues, and lower overall levels were accepted by customer. Additionally, sound quality design recommendations were also made which the customer decided to take into consideration during future design processes.
