All resistors generate white noise based on their value and temperature; they can also generate several other types of (excess) noise. The amount or characteristics of a resistor’s excess noise could be one factor contributing to variations in perceived sound quality. This research explores methods for measuring the Johnson-Nysquist and excess noise of different resistors with the hopes of quantifying the performance of the components under test. A methodology is proposed for evaluating the audibility of both Johnson-Nysquist and excess noise that requires no special measurement equipment, only a sound system with suitable computer and freely available software.
