Dolby noise reduction is currently the standard, and no better commercial alternative exists.
Some disadvantages of using Dolby noise reduction include potential loss of high-frequency detail and distortion in recordings, difficulty in playback on non-Dolby equipped devices, and the need for proper calibration and maintenance of equipment to achieve optimal results.
Dolby Labs started in the audio industry as a noise reduction specialist. This was during the era of tape based analog recording when one of the big issues was tape noise. The noise could be heard as a background hiss. Dolby's early products were noise reduction hardware that could be used during the recording and playback process to reduce the noise. It was used in virtually all domestic and professional tape machines as well as film soundtracks. Movies that used the technology normally credit Dolby with the double D logo and the "Dolby Stereo" text. The original noise reduction processes are almost obsolete with the advent of digital recording (no tape means no tape noise). Dolby have since moved into other forms of audio processing, surround sound in particular. Movies of today no longer carry the DOlby Stereo credit but Dolby Surround credits instead.
Short Answer: No. Thomas was indeed a self-proclaimed Technogeek, but is a decade or more too young to have developed the Dolby Noise Reduction or Surround Sound systems. Infact, Thomas Dolby's last name is not actually Dolby, but rather Robertson.
Dolby is used to reduce noise and make your music sound better. The difference between B, C and S is the amount of noise reduced and sound quality. Dolby C is the equivalent of 2 Dolby B's put together, however Dolby S produces sound similar in quality to that of a CD.
The best noise reduction rating available for earplugs is typically around 33 decibels.

The best earmuffs with the highest noise reduction rating available on the market are the 3M Peltor X5A earmuffs, offering a Noise Reduction Rating (NRR) of 31 decibels.
The highest noise reduction rating earplugs available on the market are typically rated at around 33 decibels.
The stock they are touting is DOLBY. Dolby originated the noise reduction technology that was such a boon since the 70s and 80s, and now they are expanding into 3D sound. Could be a worthwhile tip, this one.
The highest NRR earplugs available on the market for maximum noise reduction are typically rated at around 33 decibels.
The noise reduction rating (NRR) is a measure of how well hearing protection devices, like earplugs or headphones, can reduce noise exposure in decibels. A higher NRR indicates better noise reduction. In the case of noise-canceling headphones, a higher NRR means they can effectively block out more external noise, providing better overall noise reduction and a quieter listening experience.
