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.

What is the opposite of noise?
The opposite of noise is silence, or quiet (noun).
How can I use a Johnson noise calculator to determine the level of noise in a circuit?
To determine the level of noise in a circuit using a Johnson noise calculator, you need to input the resistance and temperature of the circuit into the calculator. The calculator will then provide you with the Johnson noise voltage, which represents the level of noise in the circuit.
Do clouds make noise?
No, clouds do not make noise.
Is silence a noise?
silence is illusion noise is everywhere except in space Improved (by Sunrise Moon): No, silence is not a noise because a noise is sound, and sound can be heard, so can you hear silence? No...so it isn't a noise I don't think.
What is the noise level distance formula used to calculate the distance between two points based on their respective noise levels?
The noise level distance formula calculates the distance between two points based on their noise levels. It is typically represented as: Distance ((Noise level 1 - Noise level 2)2).

What does noise abatement?
Noise abatement is reduction of the intensity of noise being imposed on someone who is not making the noise.

What is technical noise?
Technical noise is also considered physical noise. Physical noise is anything that prevents you from hearing something such as adult noises,White noise and background noises are technical noise.
What is the difference between white Gaussian noise and additive white Gaussian noise?
A Gaussian noise is a type of statistical noise in which the amplitude of the noise follows that of a Gaussian distribustion whereas additive white Gaussian noise is a linear combination of a Gaussian noise and a white noise (white noise has a flat or constant power spectral density).
What is impulse noise in an image?
