IEC 60645-3:2020 specifies a means of describing the physical characteristics, in terms of electrical waveforms, of audiometric reference and test signals of short duration and methods for their measurement. The object of this document is to ensure that audiometric stimuli of short duration are specified and measured in the same way and that the calibration of equipment using such signals is carried out using defined methods. This document does not describe the method of use of short-duration te...view more

ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one
or several building components. This document considers only laboratory measurements.
This part of ISO 10848 specifies measurement methods to be performed in a laboratory to characterize
the acoustic radiation of a building element when mechanically or acoustically excited. The measured
quantities can be used to compare products, or to express a requirement, or as input data for prediction

EN-ISO 16283-2 specifies procedures to determine the impact sound insulation using sound pressure measurements with an impact source operating on a floor or stairs in a building. These procedures are intended for room volumes in the range from 10 m3 to 250 m3 in the frequency range from 50 Hz to 5 000 Hz. The test results can be used to quantify, assess and compare the impact sound insulation in unfurnished or furnished rooms where the sound field may or may not approximate to a diffuse field.
