WebHow is Sound Intensity Measured? There are two main types of sound intensity probes: Pressure-velocity (PU) probes: one microphone, one particle velocity sensor Advantage: sound intensity can be directly calculated using Equation 1 above, which is applicable over a wider frequency range Disadvantage: PU probes are more fragile and more costly. WebMany times, an estimate for THD is obtained by making what is called a Total Harmonic Distortion plus Noise, or THD+N measurement. THD+N figures are obtained by measuring the total energy present in the output, …

This measurement is especially important … WebExpressed in decibels, the dynamic range is 20 log (Vmax/Vmin). For example, a device with an input range of ±10 V and a dynamic range of 110 dB will be able to measure a signal as small as 10 µV. Thus, the input range and the specified dynamic range are important for determining the needs of your instrumentation system. Analysis [ edit]
