Why does the SOFAR channel exist?
SOFAR is an ocean “channel” that allows sound to carry great distances. At the height of World War II, scientists tested a theory that low-frequency sound could travel long distances in the deep ocean. They deployed a hydrophone from their research vessel, which was anchored off of Woods Hole, Massachusetts.
What is a Sofar event?
What’s a Sofar Sounds show? Sofar transforms everyday spaces – like a rooftop or retail shop – and turns them into captivating venues for secret, live shows, creating an immersive experience that brings guests and artists closer together. Each Sofar is small and typically features three diverse acts, with no headliner.
What is the Sofar zone?
SOFAR channel, in full sound fixing and ranging channel, zone of minimum sound speed in the oceans that occurs at depths of approximately 1,000 metres (3,300 feet). In this region, pressure, temperature, and salinity combine to inhibit the movement of sound through the water medium.
How is the SOFAR channel formed?
The SOFAR channel is formed by the interplay between changes in ocean temperature and pressure with increasing depth. Temperature and pressure are the two main factors that determine the speed of sound in the ocean.
What is the difference between sonar and sofar?
As nouns the difference between sonar and sofar is that sonar is while sofar is a system for determining the position of vessels lost at sea by means of explosive sounds.
What is the speed of sound in the SOFAR channel?
At the surface, sound travels at a brisk ~1,530 m/s, and starts to slow down as we go deeper. Right at this critical depth of 1,000 meters, sound gets as slow as ~1,500 m/s, but then starts to speed up again as we keep diving to the ocean floor.
Where is Sofar Sounds based?

What causes the Sofar layer and shadow zones in the ocean?
Within the ocean, the speed of sound varies with changes in depth that accompany normal changes in temperature and pressure. Specific combinations of temperature, pressure, and salinity may act to create shadow zones, or reflective layers, that are resistant to the propagation of sound waves.

How does Sofar Sounds make money?
The majority of these (~90%) put on shows that are free to attend, then pass-the-hat to collect money for show expenses and artists, with $0 going back to the business. The rest of the independent cities sell tickets online and pay artists a flat guarantee ($100 per act in the U.S.).
What is the Sofar layer?
The SOFAR channel (short for Sound Fixing and Ranging channel), or deep sound channel (DSC), is a horizontal layer of water in the ocean at which depth the speed of sound is at its minimum. This phenomenon is an important factor in ocean surveillance.
