MEASUREMENT BEYOND THE ATOMIC LEVEL

The setting is surreal. As you drive into the Satsop Business Park in rural Elma, Washington (pop. 3500, max), eyes immediately fixate on the looming 481'-tall cooling towers of an abandoned nuclear facility!

Remnants of the largest nuclear power plant construction project in the United States, the site was mothballed in 1983, in part due to concerns triggered by reports of what had happened at Pennsylvania's Three Mile Island four years earlier.

The abandoned site's reactor and turbine buildings now house NWAA Labs, a 13-year-old independent laboratory that tests loudspeakers and materials for the audio, acoustics, and construction industries. NWAA Labs' founder is Stanford-educated electrical and mechanical engineer Ron Sauro, 76. Initially, Sauro juggled work at NASA with performing as the Vox organist of the 1963 Gold Record-earning group the Rivieras.³ Sauro later became a sound system designer/installer for churches and arenas. He began measuring speakers and contributing papers to the Journal of the Audio Engineering Society circa 1990 and opened his first speaker-measuring operation, Western Electro-Acoustic Labs, in 2005.

To say that NWAA Labs is unique is a grand understatement. The lab, which boasts the two largest reverberation chambers in the world, occupies a temperaturestable building designed to withstand a 10-megaton nuclear blast on its roof and a magnitude 10 earthquake. The building rests on an exceedingly stable sandstone layer roughly 10,000' thick. After excavating a 500' × 500' hole to a depth of 300', the Washington Power Supply System (WPSS) dug a 6"-wide trench around the foundation slab. By separating the foundation’s sides from the earth’s crust, the trench was intended to prevent earthquake damage and transmission of vibration and noise.
