A standard refrigerator runs at approximately 1 sone (roughly 28 dB) .
In the field of telecommunications and electrical utilities, "134" frequently appears as a designation for a specific tutorial paper or technical report. sone 134
SONE 134 applies to electric saunas that are designed to be used in accordance with the National Electric Code (NEC) and other relevant electrical codes. The standard covers saunas that are heated electrically and are intended for use in locations such as private homes, apartments, hotels, and health clubs. It does not apply to saunas heated by other means, such as steam or infrared radiation, unless specifically stated. A standard refrigerator runs at approximately 1 sone
The primary goal of SONE 134 is to provide a comprehensive set of requirements for the design, construction, and testing of electric saunas. These requirements aim to minimize the risks associated with the use of electric saunas, including electrical shock, fire, and burns. The standard covers both portable and stationary electric saunas intended for residential and commercial use. The standard covers saunas that are heated electrically
There is an IEEE (Institute of Electrical and Electronics Engineers) tutorial paper titled "SONET Radio/Fiber Optic Applications in Electrical Utilities (TP 134)" .
