Acoustics and vibration. Laboratory measurement of vibro-acoustic transfer properties of resilient elements - Principles and guidelines Ingestion-build-52208 In some counting situations1 Scope This part of ISO 10846 explains the principles underlying ISO 10846 2, ISO 10846 3, ISO 10846 4 and ISO 10846 5 for determining the transfer properties of resilient elements from laboratory measurements, and provides assistance in the selection of the appropriate part of this series. It is applicable to resilient elements that are used to reduce a) the transmission of audio frequency vibrations (structure borne sound, 20 Hz to 20 kHz) to a
