Noise (as related to a radio signal I suppose) is an unwanted signal being processed by a receiver. Attenuation is a loss of the intended signal before it gets to the receiver (usually due to such things as distance, line of sight obstructions, etc.
Attenuation refer to the inter mixing of the waves having different frequencies and also known as noise.
We all like musical sounds and we hate static annoying noise.
for a white noise the psd is flat i.e the distribution of energy over central freq is 1 and for gaussian noise as the name says the psd is normally distributed.
Clocks make noise... like alarms or chimes... watches are silent...
6 dB is a "good" attenuation.
nothing

a noise of a computer is lower than atelivision
Music can be coined as structured, organized noise.
the difference between voice and noise is the voice is somebody speaking and it is smooth and mellow and noise means loud and mad if you think say noise in your head when you say noise you just no what it means loud big and it could mean danger as well.
In CATV system, insertion loss define as loss in directional coupler or TAP connector. typically 1 dBuv, while attenuation is generally describe as loss in transmission (splitter).

A loud noise...
It is really a personal impression. Does a rapper makes noise or is he singing with his voice?

i dont know you guide me
RG-11/U is 75ohm and is usually triple/quad shielded and typically has a maximum attenuation of 3.65. RG-213/U is common form amateur radion and is 50 ohms and is single shielded with about a 5.95 attenuation.
