The keyword refers to a highly specific intersection of Japanese acoustics, historical audio engineering, and standard industrial noise-level metrics. In Japanese technical documentation, a "sone" (ソーン) is a unit of perceived loudness, while "153" typically denotes a specific product classification, industrial regulation standard, or landmark frequency benchmark.

Japan’s high-speed rail network (the Shinkansen) must minimize environmental noise, especially when trains enter tunnels at speeds exceeding 300 km/h—a phenomenon known as "tunnel boom." Sound profiles hitting the 153-sone threshold at the point of origin must be mitigated using aerodynamic nose designs and sound-absorbing track walls to protect trackside residential zones.

: Legends such as those of the deity Susanoo-no-Mikoto date back to early Japanese texts like the Fudoki , which were preserved in extracts and later retellings through various periods of Japanese history.

The peak registered at 153 sones when measured 1 meter from the source—a level deemed "threshold of dramatic impact without pain." Restoration guidelines now reference this exact value as the ideal acoustic event for traditional percussion.
