Abandoned Nuclear Plant in the U.S. Transforms into Ultrasonic Sound Laboratory. Structure Used for High-Precision Acoustic Research

In the heart of Washington state, two cooling towers nearly 500 feet (approximately 152 m) tall catch the eye on the horizon. They belonged to the former Satsop nuclear plant, a grand project that was never completed. Today, what could have been a symbol of the past has turned into something unexpected: a world-class acoustic laboratory.

Nuclear Plant Became Sound Testing Center

Construction of the nuclear plant started in 1957. The goal was to provide energy to meet the growing demand in the state. However, the project was canceled in 1982 due to high financial costs.

The site, which was part of the largest nuclear power plant construction plan in the United States, was abandoned even before it became operational.

Unique Structure Attracts Experts and Creators

NWAA Labs was founded by Ron Sauro, a former NASA scientist with degrees in electrical and mechanical engineering from Stanford University. He transformed the reinforced spaces of the old plant into a high-precision sound testing environment.

According to Sauro, the site is ideal for measuring noise in building materials, household equipment, and even aircraft structures. Examples mentioned include crew cabins and noisy washing machines.

The structure of the building is also impressive: it was built to withstand a 10-megaton nuclear explosion and earthquakes of magnitude 10.

Largest Reverberation Chamber in the World

One of the highlights of the laboratory is its reverberation chambers, considered the largest in the world. These are environments where sound can be analyzed under specific conditions, with minimal external noise. The nuclear plant building features a floating room within another floating room, separated from the outside world by 7.5 meters of concrete.

“At very low frequencies, NWAA Labs can accurately measure down to 25 Hz because it is located in a floating room within a floating room, separated from the outside world by about 7.5 meters of concrete, ” Sauro explained. He states that at 1000 Hz, background noise reaches -43 dB, which is extremely quiet.

Additionally, NWAA Labs has anechoic chambers—rooms that simulate an echo-free environment, commonly used to test speakers and other audio devices. The old turbine room has also been repurposed for free field testing.

Music, Games, and Film Interested in the Space

The laboratory is now rented by the hour. Among the clients are musicians, sound designers for video games, and even filmmakers. The apocalyptic visual and rare acoustic features attract creative professionals.

The nuclear plant, radiation-free as it was never activated, has already appeared in films from the Transformers franchise. It continues to function as a testing center, offering up to 160 dB of variation between rooms for detailed measurements. A piece of the U.S. nuclear past is now helping shape the future of sound.

Engineers want to carve through Africa with a giant canal to bring water from the world’s second-largest river to a dying lake on the edge of the Sahara Desert that has already lost 90% of its water.

A giant brown band visible from space, approximately 8,850 kilometers long, connected Africa to America in the Atlantic Ocean, and satellites revealed that it is neither land nor pollution, but the largest accumulation of seaweed in the world, which broke records in 2025.

Workers were opening a modern road in Dover when they found, 6 meters below the asphalt, a 3,500-year-old boat made of stitched oak and plant fibers.

Instead of burning or burying old tires, an American city is transforming about 2,000 of them into the street itself, paving its first sections with a quieter and more durable rubber asphalt.

In just one cast, fishermen are surprised to capture 14,096 mullets in Bombinhas and close a historic season with 58,000 fish; scene recorded in the Santa Catarina paradise marks the last day of the 2026 season.

Consumers eat six times more chicken than in the 1960s, global meat supply quadruples in 60 years, and FAO report reveals the invisible cost on the plate: livestock could drive 80% of the increase in agricultural emissions over the next decade.

Motorcyclist sees excavator arriving at the edge of a river in Bosnia, calls neighbors in minutes and turns a hydroelectric project into a resistance lasting more than 10 years with five expired concessions.

Brazil invests R$ 293.8 million to remove 552,000 m³ of submerged rocks from the Tietê River, deepen 16 km of the channel by 3.5 meters, and allow larger convoys on the waterway that connects cargo from the Midwest and Southeast to the Port of Santos.

Young Brazilian passionate about engines turns childhood fascination into a career: at 22, he interns in motor development at WEG, amasses thousands of followers, and reveals how he became a reference in industrial technology.

Isolated in the Atlantic, an African island with about 5,000 residents reported dynamite explosions at a construction site, feared damage to water and crops, and ended up almost a year without internet.

Brazil has already created globally successful games, trained professionals for major studios, and won over players abroad, but it still hasn’t managed to produce its own AAA blockbuster.

Someone paid $1.3 million for a tiny parking space, only 12.5 m².
