Audio. Audio signals include speech but also music and all types of sounds. On a compact disc, the audio signal is limited to a maximum frequency of 20 kHz. It is sampled at 44.1 kHz and each sample is coded on 16 bits. The bit rate of the resulting PCM code is 706 kb/s.

The first is the signal level. There is a whole continuous range of signal levels, but generally they fall into a few categories. Audio signals are measured in both volts and decibels (dB) relative to 775 millivolts. Microphone level - very low level signal, on the order of a few millivolts, -60 dB

In electrical terms, noise is defined as the unwanted form of energy which tends to interface with the proper reception and the reproduction of transmitted signals. Electronic Devices unwanted random addition to the signal are considered as Noise. Their are various types of Noise presents.
Audio Signal Levels Explained: Mic, Instrument, Line, and ...

Mic, instrument, line, and speaker level signals differ when it comes to their voltage levels. From the weakest to strongest voltage level, it goes mic level signal, instrument level signal, line level signal, and then speaker level signal. The exact level of a signal depends on things like how loud a sound source is, so it makes the most sense ...

Phase noise: Phase noise is a form of RF noise that is visible on radio frequency, and other signals. It appears in the form of phase jitter or perturbations on the signal. These manifest themselves as sidebands that spread out either side of the signal or carrier. Phase noise can affect a signal or system in a variety of ways.

V. SIGNAL-TO-NOISE RATIO Noise is usually expressed as a power because the received signal is also expressed in terms of power. By knowing the signal to noise powers the signal to noise ratio can be computed. Rather than express the signal to noise ratio as simply a number, can be it expressed in terms of decibels. Signal-to-Noise Ratio = 10 log
Intro. to Signal Processing:Signals and noise
https://terpconnect.umd.edu/~toh/spectrum/SignalsAndNoise.html
The quality of a signal is often expressed quantitatively as the signal-to-noise ratio (S/N ratio), which is the ratio of the true underlying signal amplitude (e.g. the average amplitude or the peak height) to the standard deviation of the noise. Thus the S/N ratio of the spectrum in Figure 1 is about 0.08/0.001 = 80, and the signal in Figure 3 has a S/N ratio of 1.0/0.2 = 5.
