Description

The aim of the project, which is carried out under the auspices of EUROMET, is to develop a technique for free-field calibration of measurement microphones by comparison with laboratory standard microphones. Reflections from the set-up combined with the uncertainty in positioning the microphones often result in unacceptably large calibration errors. The reflections from the source and from the mechanical structures are studied together with methods of analysis based on time-selective measurements in order to reduce the influence on the resulting calibration uncertainty.
