- Communicate the process of accurately measuring sound power levels of positive displacement hydraulic pumps commonly used in ground vehicle steering systems. This recommended practice defines the pump mounting (pulley@ belt tension@ isolation)@ operating conditions (fluid@ speed@ temperature@ pressure)@ room acoustics@ instrumentation@ noise measurement technique and data acquisition setup to be used. Included are recommendations for test sample size@ and format for data presentation eporting.PurposeRecord a common method to perform testing among vehicle manufacturer and pump suppliers.
