Cocoon features a ported enclosure and a built-in, 2-way speaker system with dual-layer woofers for resounding low frequency response.
What does Dr Paxton - who is using the Loch Ness phenomenon to analyse how science handles anecdotal and low frequency data - think?
BBC: Loch Ness Monster: Is Nessie just a tourist conspiracy?
More specifically, researchers have been interested in the link, if any, between the extremely low frequency magnetic fields generated by these lines and childhood leukaemia.
Usually, elephants produce much deeper sounds, sometimes of such a low frequency that they are outside the range of human hearing, and these calls can boom many miles away.
The nuclear test monitors pick up "infrasound", or low frequency, waves from about 20 meteors a year -- "if conditions are right, perhaps as small as a pea, " she said.
Such damage has long been suspected, since whales employ their own form of sonar for navigating and hunting, and also use sonar-like low frequency sound for communicating with each other (so-called whale song).
So for the world as a whole, if a financial transactions tax put a bit of a dampener on financial innovation and trading (whether low frequency or high frequency), that would probably be no reason to weep - unless (to state the obvious) investment banking is your life.
Extrapolating from Dr Freund's laboratory experiments, the strain in a real-life geological fault such as the San Andreas could, as it shifted, generate hundreds of thousands of amperes per cubic kilometre in a fluctuating pattern that would cause very low frequency radio waves to be emitted, thus disrupting the ionosphere.
"Low-frequency spectrum on a network as big as ours is a real notspot-killer, " he said.
Furthermore, WE HAVE EXPLICITLY TAKEN INTO ACCOUNT THE LOSS OF LOW-FREQUENCY VARIANCE IN OUR ESTIMATES OF UNCERTAINTY.
It is designed to detect the low-frequency radio pulses emitted by lightning strikes.
ECONOMIST: A new way of protecting planes from the ash from volcanoes
Residents of Waubra, a town near Victoria's biggest wind generator, recently complained that low-frequency noise was causing headaches and earaches.
Over the years, the government has taken steps to address the problem, including regulating low-frequency noise like water pumps, and reducing maximum decibels.
Furthermore, the LightSpeaker's 2.5-inch wide dispersion driver uses digital signal processing to optimize high- and low-frequency output for a full spectrum of sound.
The sensors work by detecting extremely low-frequency electrical activity over a distance of 5 microns (one micron being equal to one millionth of a metre).
FORBES: Can Forensic Scientists Tell How Old A Fingerprint Is?
Its scientific committee said low-frequency ambient marine noise levels had increased in the northern hemisphere by two orders of magnitude over the last 60 years.
BBC: NEWS | Science/Nature | The deafening sound of the seas
The Acoustic Thermometry of Ocean Climate (ATOC) project is asking to extend its two-year permit to operate low-frequency sonar under the water off Kauai another five years.
Under the hood, PLAYBAR gets its punch from nine individually amplified speakers: six mid-woofers to deliver deep, rich low-frequency sounds, and three tweeters for crystal clear high-frequency detail.
The low-frequency aperture array antennas will be positioned in Australia.
The insider threat has traditionally been viewed as a high-consequence but low-frequency risk, and many IT organizations have found it challenging to develop effective programs that manage that risk.
The DA-F60 incorporates neodymium magnets and a passive radiator to produce results typically found in high-end Hi-Fi audio systems, including tuned low-frequency reproduction and virtually no distortion even at high volumes.
ENGADGET: Samsung introduces its CES audio hardware, claims a world first
Because of the distance that low-frequency sound waves can travel under water, a set of four ships emitting sound at 235 decibels could monitor 80% of the world's oceans for submarines.
ECONOMIST: The American navy may soon have a whale of a problem
And Project SHIELD provides fidelity and dynamic range never before available on a portable device, through its custom, bass reflex, tuned port audio system -- with twice the low-frequency output of high-end laptops.
ENGADGET: NVIDIA unveils Project Shield, a Tegra 4-powered Android gaming handheld
Although they have not been found to cause any harm, the cables on conventional pylons, which transmit a three-phase alternating current, generate a strong electric field and a continuous buzz of low-frequency radio waves.
The Navy disputes his assessment, saying this year's humpback whale season was normal, and more whales than ever before were seen in March 1998, when biologists studied humpbacks' response to the Navy's Low-Frequency Active Sonar (LFAS) equipment in Hawaiian waters.
It's always nice to see an old tech stage a comeback and this time it's happening around the coasts of Europe, with nine low-frequency radio transmitters substituting for GPS' satellite-based system. eLoran's radiowave-based system is stronger than satellite signals and less jammable, based on the Loran system that was previously used for shipping navigation by both the British and US navy over 50 years ago.
The company produces more than 15, 000 standard products, including amplifiers, data converters, and low-power radio frequency devices.
Europe's business market is more limited, too: Fewer routes have enough traffic to sustain the frequency of low-cost departures that could attract business passengers.
