Digital Audio Basics: Audio Sample Rate and Bit Depth
https://www.izotope.com/en/learn/digital-audio-basics-sample-rate-and-bit-depth.html
The most common audio sample rate you’ll see is 44.1 kHz, or 44,100 samples per second. This is the standard for most consumer audio, used for formats like CDs. This is not an arbitrary number. Humans can hear …

When comparing bitrate, or the amount of data transferred per second, High-Resolution Audio’s bitrate (9,216 kbps) is nearly seven times higher than that of CDs (1,411 kbps) and almost 29 times higher than that of MP3s (320 kbps). And the higher the bitrate, the more accurately the signal is measured.

The sampling rate of 44.1 kHz came to be that of the Compact Disc. Even though CD has no video circuitry, the equipment used to make CD masters was originally video based and determined the sampling rate. This sounds good, except that NTSC video actually runs at 29.97 frames per second, which makes the field rate come out to 59.94 instead of 60.
Explanation of 44.1 kHz CD sampling rate - Columbia University

The CD sampling rate has to be larger than about 40 kHz to fulfill the Nyquist criterion that requires sampling at twice the maximum analog frequency, which is about 20 kHz for audio. The sampling frequency is chosen somewhat higher than the Nyquist rate since practical filters neede to prevent aliasing have a finite slope. Digital audio tapes (DATs) use a sampling rate of 48 kHz.

The most common values for the sampling rate is the aforementioned 8kHz (most common for telephone communications), 44.1kHz (most common for music CDs), and 48kHz (most common for audio tracks in movies). Lower sampling rates mean less samples per second, which in turn mean less audio data, since there is a smaller number of sample points to represent the audio.

44.1 kHz (44100 Hz) is the sampling rate of audio CDs giving a 20 kHz maximum frequency. 20 kHz is the highest frequency generally audible by humans, so making 44.1 kHz the logical choice for most audio material.

In a typical digital audio CD recording, the sampling rate is 44,100 or 44.1kHz. If you’re wondering why the frequency is so high when the human ear can only hear frequencies up to 20kHz at best. It’s because of the Nyquist-Shannon sampling theorem. Christopher D’Ambrose puts the hearing ability of the normal middle-aged adult at 12-14 kHz).
