Sound Quality Testing of Dialysis System

Industry: Medical

Applications: SVQ Target Development

A medical corporation that provides research and development for major corporate clients selected Sound Answers to both measure sound quality performance and define a sound quality test procedure on a home dialysis system. Operating acoustic measurements were collected within a hemi-anechoic chamber. Binaural measurements were utilized in the analysis of time domain, narrow band spectra, and sound quality metrics. A preference equation was derived based on key attributes of the sounds from the analysis techniques discussed and a formal jury study. This testing allowed the customer to improve its customer’s perception of quality for their dialysis system by moving forward from subjectively capturing customer preferences to using objective measures and to also drive development work with objective data for future products.
