acoustic waveguide

An acoustic waveguide is a physical structure for guiding sound waves.

Bose uses similar patented technology on their Wave and Acoustic Waveguide music systems.

The technology the researchers used is called Ocean Acoustic Waveguide Remote Sensing.

Acoustic transmission line - a type of technology used in some loudspeakers, and based on the principles of an acoustic waveguide.

An acoustic transmission line is the use of a long duct, which acts as an acoustic waveguide and is used to produce or transmit sound in an undistorted manner.

They used an underwater imaging technology called Acoustic Waveguide Remote Sensing and conventional fish-finding sonar to observe the herring over several days in autumn when they spawn.

The transmission line acts as an acoustic waveguide, and the padding both reduces reflection and resonance, and also slows the speed of sound within the cabinet to allow for better tuning.

Using a system called Ocean Acoustic Waveguide Remote Sensing, the team can observe shoals of fish as much as 25 miles across, compared to past echo-sounders which cover only a small area.

Precisely matched Adamson Acoustic Waveguides, provide exceptional beamwidth control while our patented M200 midrange driver and a 1.5" Ferrofluid cooled, high frequency driver deliver extreme mid-high frequency output.

The Portable has a battery life ranging from 3 to 14 hours depending on bass and listening volume Though slightly taller and slimmer than the original, it has an "air duct" on the handle and uses an acoustic waveguide.

In music, low frequency sounds, including near infrasound, can be produced using acoustic waveguide methods, such as a large pipe organ or, for reproduction, exotic loudspeaker designs such as transmission line, rotary woofer, or traditional subwoofer designs about 10 times larger in order to octave down below their normal limit.

An ultrasonic horn (also known as acoustic horn, sonotrode, acoustic waveguide, ultrasonic probe) is a tapering metal bar commonly used for augmenting the oscillation displacement amplitude provided by an ultrasonic transducer operating at the low end of the ultrasonic frequency spectrum (commonly between 15 and 100 kHz).
