A medical equipment manufacturer requested the assistance of Sound Answers in estimating the impact of the sound of a dialysis machine on the sleep disturbance of a patient. Acoustic binaural recordings were measured to mimic what the patient would hear in the course of normal operation of the device. Sound Answers developed a method of analysis using sound quality metrics to best understand what impact the machine would have on sleep disturbance. These results then can be used by the manufacturer to set target levels and metrics for product development.
