Indagine sperimentale sul rumore intrinseco della strumentazione per misurazioni fonometriche

An experimental investigation has been carried out to determine the self-generated noise from the instrumentation used for sound measurements. This noise, especially in the case of measurements at low sound levels, is often comparable with that of interest and, therefore, affects the acquired data. The instrumental noise, of a random nature, can be determined by the analysis "Coherent Output Power COP", allowing its masking from measurement of interest.
