Impact of personal video recorder/digital video recorder on hard disk drive acoustic requirements

摘要

In recent years the impact of the PVR/DVR (Personal Video Recorder/ Digital VideoRecorder) market has grown substantially. This growth has a direct impact on the acoustictest labs that make sure the systems meet the manufacturer’s specification for noiseemissions. To date the standards have not addressed this growth and subsequently have notprovided guidance as to standardized methods of test for these systems. This paper willshow the impact of the market and provide a proposed addition to the appropriate acoustictest standards.
