If electrons flow across a barrier, then they have discrete arrival times. Those discrete arrivals exhibit shot noise. The output noise level of a shot noise generator is easily set by the DC bias current. Typically, the barrier in a diode is used. [4] Different noise generator circuits use different methods of setting the DC bias current.
It can also require the use of ear protectors on passengers. Unlike motorboats, the sound generators on these vehicles are airborne, resulting in more noise impact. Florida (Section 327.65) requires a maximum level of 90 DB(A). Maine (Title 12 Section 13068-A)has three levels: operating, operating test and stationary test
Different types of noise are generated by different devices and different processes. Thermal noise is unavoidable at non-zero temperature (see fluctuation-dissipation theorem), while other types depend mostly on device type (such as shot noise, [1] [3] which needs a steep potential barrier) or manufacturing quality and semiconductor defects, such as conductance fluctuations, including 1/f noise.
If the pressure-to-intensity ratio is large then even a small phase mismatch will lead to significant bias errors. In practice, sound intensity measurements cannot be performed accurately when the pressure-intensity index is high, which limits the use of p-p intensity probes in environments with high levels of background noise or reflections.
