Explanation of 44.1 kHz CD sampling rate - Columbia University
http://www1.cs.columbia.edu/~hgs/audio/44.1.html
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 2 Most Common CD Sampling Rates: 44.1kHz & 48kH. First, a little background: When you sample an audio waveform, you have a choice as to how many samples you take per second. Over the years, a number of standards have developed; in digital media used for entertainment purposes, the two most common sampling frequencies are 44.1 kHz and 48 kHz.
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 frequencies between 20 Hz and 20 kHz.

High-Resolution Audio files have a sampling frequency of 96 kHz/24 bit, which is significantly higher than the 44.1 KHz/16 bit sampling frequency of CDs. How does that translate to the listening experience? Listening to High-Resolution Audio allows you to pick up on the subtle details and nuances that you would hear in a recording studio.
What is the best audio sampling frequency - LmK Music ...
https://lmkprod.com/best-audio-sampling-frequency/
The best sampling frequency is 2 times the frequency of the highest frequency of your incoming signal. Which, in case of music, is 20.000 Hz (20Khz). Therefore: 2 x 20.000 = 40.000. There we go: the best frequency for audio sampling is around 40Khz.

A higher sample rate tends to deliver a better-quality audio reproduction. Sample rates are usually measured per second, using kilohertz (kHz) or cycles per second. CDs are usually recorded at 44.1kHz – which means that every second, 44,100 samples were taken. If you can master sample rates, you can create more accurate recordings.
High bitrate audio is overkill: CD quality is still great ...

Chances are near 100% that your current library is perfectly fine. You only need a sample rate of 44.1kHz If you’ve looked at your music player’s information tab, you may notice some of your songs have sample rates of 44.1kHz, or 48kHz. You may also notice that your DAC or a phone like the LG V30 support files with sample rates up to 384kHz.

The sample rate is measured in hertz(Hz). According to Nyquist Sampling theorem the sampling frequency to produce the exact original waveform should be double the original frequency of the signal. The human hearing bandwidth is 20Hz-20kHz, the audio sampled can be at the rate above 40kHz.(Usually 44.1KHz is preferred).

For its first CD players, Philips realized that by adding three zero-valued samples in between each valid audio sample, the effective sample rate would be increased to 176.4kHz, and the unwanted images, instead of lying 22.05kHz on either side of 44.1kHz and its multiples, would now lie at either side of 176.4kHz and its multiples.
