The Flood. Water was added, and the ecosystem came to life. CO2 was pumped in to fuel the lush greenery, turning the tank into a vibrant, emerald "Glass Forest."
To understand the significance of Sone 363, one must first contextualize it within the framework of measurement standards. The term "sone" itself is a recognized unit of measurement used to quantify perceived loudness. It was proposed by Stanley Smith Stevens in 1936 and has since become a standard in acoustics and noise control engineering. Unlike decibels, which measure sound pressure on a logarithmic scale, the sone scale is linear. One sone is arbitrarily set equal to the loudness of a 1,000-hertz tone at 40 decibels above the normal threshold of hearing. Consequently, a sound measured at two sones is perceived as twice as loud as a sound at one sone. sone 363
