What is psophometric noise?
This is background noise, so small that you might need a psophometer to measure it. A psophometer would have an agreed bandwidth and be looking around -40 to -80 dBm. It would not be looking for a single tone but energy in the band specified, such as 0 - 4 kHz for a telephone line of 0 - 20 kHz for a music source. Sources of this noise would be weather, Boltzmann's noise from noisy and ageing or 'shot' components.

Why thermal noise is called white noise?
