2. Sound transmission class - Wikipedia

   en.wikipedia.org/wiki/Sound_transmission_class

   Examples of structural decoupling in building construction include resilient channels, sound isolation clips and hat channels, and staggered- or double-stud framing. The STC results of decoupling in wall and ceiling assemblies varies significantly depending on the framing type, air cavity volume, and decoupling material type. [ 14 ]

3. SOFAR channel - Wikipedia

   en.wikipedia.org/wiki/SOFAR_channel

   The SOFAR channel (short for sound fixing and ranging channel), or deep sound channel (DSC), [1] is a horizontal layer of water in the ocean at which depth the speed of sound is at its minimum. The SOFAR channel acts as a waveguide for sound, and low frequency sound waves within the channel may travel thousands of miles before dissipating.

4. Underwater acoustics - Wikipedia

   en.wikipedia.org/wiki/Underwater_acoustics

   Underwater acoustics (also known as hydroacoustics) is the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water, its contents and its boundaries. The water may be in the ocean, a lake, a river or a tank. Typical frequencies associated with underwater acoustics are between 10 ...

   Resilient Sound Isolation Clips are manufactured in the United States and sold throughout the Americas. RSIC-1 was engineered to provide noise control and be both cost effective and environmentally friendly. PAC International's noise control products help buildings exceed the International Building Code requirements for both fire and sound. The ...

6. Speed of sound - Wikipedia

   en.wikipedia.org/wiki/Speed_of_sound

   The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. More simply, the speed of sound is how fast vibrations travel. At 20 °C (68 °F), the speed of sound in air is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.91 s or one mile in 4.69 s.

7. Underwater acoustic communication - Wikipedia

   en.wikipedia.org/wiki/Underwater_acoustic...

   Underwater acoustic communication is a technique of sending and receiving messages in water. [1] There are several ways of employing such communication but the most common is by using hydrophones. Underwater communication is difficult due to factors such as multi-path propagation, time variations of the channel, small available bandwidth and ...
