During the 1930s American engineers developed their own underwater sound-detection technology, and important discoveries were made, such as the existence of thermoclines and their effects on sound waves. Americans began to use the term SONAR for their systems, coined by Frederick Hunt to be the equivalent of RADAR.

Over the next three years he developed a sophisticated defence known to the British as the Kammhuber Line. Kammhuber began by expanding the illuminated zone to extend from occupied Denmark to northern France. Early warning relied on Freya radar, sound detection devices and observers. Control of the night fighters and AAA batteries was provided by short-range Würzburg sets.

Some GObC volunteers also set up sound-detection equipment at their own expense to search for the sound of aircraft engines at night, bad weather, and during heavy cloud cover, when visual sightings were impossible. Many GObC volunteers went to great lengths in the enthusiasm for their operations, such building this tower. Department of National Defence image.

This work, for the Anti-Submarine Division of the British Naval Staff, was undertaken in utmost secrecy, and used quartz piezoelectric crystals to produce the world's first practical underwater active sound detection apparatus. By 1918, both France and Britain had built prototype active systems. The British tested their ASDIC on in 1920, and started production in 1922.

Later, acoustic torpedoes were used. Early in World War II (September 1940), British ASDIC technology was transferred for free to the United States. Research on ASDIC and underwater sound was expanded in the UK and in the US. Many new types of military sound detection were developed. These included sonobuoys, first developed by the British in 1944 under the codename High Tea, dipping/dunking sonar and mine-detection sonar.

Audio Analytic sells ai3, a software package that is embedded on a device, along with an assortment of sound profiles that the software can recognise, including warning alarms, window breakage, an infant crying, and voice activity. Audio Analytic developed the Polyphonic Sound Detection Score (PSDS), a metric for evaluating the performance of sound recognition algorithms when applied to polyphonic sound recordings. They also released an accompanying software framework that implements the PSDS.

Counter-battery missions became commonplace, also, and sound detection was used to locate enemy batteries. A Russian armoured car, 1919 Germany was far ahead of the Allies in using heavy indirect fire. The German Army employed and howitzers in 1914, when typical French and British guns were only and .

Wood, producing a prototype for testing in mid-1917. This work, for the Anti-Submarine Division of the British Naval Staff, was undertaken in utmost secrecy, and used quartz piezoelectric crystals to produce the world's first practical underwater active sound detection apparatus. To maintain secrecy, no mention of sound experimentation or quartz was made – the word used to describe the early work ("supersonics") was changed to "ASD"ics, and the quartz material to "ASD"ivite: "ASD" for "Anti-Submarine Division", hence the British acronym ASDIC. In 1939, in response to a question from the Oxford English Dictionary, the Admiralty made up the story that it stood for "Allied Submarine Detection Investigation Committee", and this is still widely believed, though no committee bearing this name has been found in the Admiralty archives.W.

Marie "Bobbie" Dennis Poland Fish (May 22, 1900 – February 2, 1989) was an American oceanographer and marine biologist best-known for her bioacoustics research. Her research on underwater sound detection allowed the United States Navy to distinguish enemy submarines from wildlife. The United States Navy awarded her its highest civilian award, the Distinguished Service Medal, in 1966 to recognize her contributions during her twenty-two years (1948-1970) leading the "Underwater Sound of Biological Origin" project for the Office of Naval Research. She also founded the Narragansett Marine Laboratory with her husband.

Once there, G-1 began her new career as an experimental and instructional submersible. She acted as a schoolship for the newly established Submarine Base and Submarine School at New London, training officers and men of the newly expanded submarine force. Concurrently, given the entry of the United States into World War I, G-1 tested submarine nets and detector devices for the Experiment Board. She served in a similar capacity at Nahant, Massachusetts, and Provincetown, Massachusetts, assisting the destroyer and steam yacht in the development and use of sound detection devices and experiments with the "K tube," a communications device.

Sir James Woodham Menter, (22 August 1921 – 18 July 2006) was a British physicist. He was born in Teynham, Kent and was educated at the Dover Grammar School for Boys, where he won a scholarship to study Natural Sciences at Peterhouse, Cambridge. His studies were interrupted by the Second World War, during which he was engaged on trials of Under Water Sound Detection systems at the Admiralty Research Station in Fairlie, Ayrshire. He completed his degree in 1945 and did a PhD on the subject of the use of the electron microscope to examine the micro-topography of surfaces.

Hot Spot has two main advantages over its competing technology, the Snickometer and Ultra Edge, which are sound-detection based system. These two systems often produce inconclusive results indicating contact (potentially any combination of bat, pad, feet shuffling, bat handle squeak) only, whereas the Hot Spot clearly shows exactly what that ball striked. Independent testing has shown Snickometer and other competing sound based technologies are susceptible to the concept of the "Phantom Snick", where the sound of the ball whooshing past the bat sometimes creates a sound, even when the ball does not touch the bat.

The first patent for an underwater echo ranging device was filed by English meteorologist Lewis Richardson a month after the sinking of the Titanic. The First World War stimulated research in this area. The British made early use of underwater hydrophones, while the French physicist Paul Langevin worked on the development of active sound devices for detecting submarines in 1915 using quartz. In 1916, under the British Board of Invention and Research, Canadian physicist Robert William Boyle took on the active sound detection project with A B Wood, producing a prototype for testing in mid-1917.

LM found no effective treatment, so she learned to avoid conditions with multiple visual motion stimuli, i.e. by not looking at or fixating them. She developed very efficient coping strategies to do this and nevertheless lived her life. In addition, she estimated the distance of moving vehicles by means of sound detection in order to continue to cross the street. LM was tested in three areas against a 24-year-old female subject with normal vision: ;Visual functions other than movement vision LM had no evidence of a color discrimination deficit in either center or periphery of visual fields.

The animal then jabs forward multiple times until it has a good grasp of its prey in its jaw and proceeds to shake its head from side to side until it tears off a chunk of flesh. A feeding frenzy, or large swarm of other sharks, then forms as the individuals sense the blood and bodily fluids released from the prey. Sounds of struggling prey also attract groups of sharks, suggesting they use sound detection for predation. Group feeding behavior such as pack hunting or communal scavenging was observed in a study in which pieces of the same stingray were found in the stomachs of several lemon shark individuals that were caught and examined.

During the Cold War, the United States wanted to learn more about Soviet submarine and missile technology, specifically ICBM test and nuclear first strike capability. In the early 1970s the U.S. government learned of the existence of an undersea communications cable in the Sea of Okhotsk, which connected the major Soviet Pacific Fleet naval base at Petropavlovsk on the Kamchatka Peninsula to the Soviet Pacific Fleet's mainland headquarters at Vladivostok. At the time, the Sea of Okhotsk was claimed by the Soviet Union as territorial waters, and was strictly off limits to foreign vessels, and the Soviet Navy had installed a network of sound detection devices along the seabed to detect intruders. The area also saw numerous surface and subsurface naval exercises.

On 11 January 1971, W. S. Sims left Mayport with personnel from the Key West Testing and Evaluation Detachment embarked. The project consisted of six cruises, numbered 0 to 5, where W. S. Sims operated with various types of submarines in order to determine the capabilities and limitations of the installed long range underwater sound detection equipment. The tests continued throughout the year and took the escort to such ports as New Orleans; Fredriksted, St. Croix; San Juan, Puerto Rico; and Nassau, Bahamas. The ship returned to Mayport in time for Thanksgiving and, between 22 November and 31 December 1971, was involved in a fleet standdown period, during which officials representing the squadron, flotilla, and type commanders conducted a series of inspections.

McNair's report on defending the coasts of Hawaii indicated that sufficient sound detection and illumination equipment like this was critical to success. The McNair board carried out numerous tests of coast artillery and bomber aircraft in a variety of conditions, and compiled tables and charts to depict the results. The panel concluded that coastal artillery was sufficient for shore defense, provided that adequate listening and lighting equipment for detecting and illuminating enemy ships and planes was available, and that bombers were less accurate, but more effective at destroying enemy ships at longer distances from shore, provided they could overcome obstacles including inclement weather. In addition to his work on the coastal defense problem, McNair was also responsible for directing a review of War Plan Orange, the Army and Navy joint defense plan for countering an attack on Hawaii by Japan.

Several were shot down in flames by British defenders, and many others destroyed in accidents. New designs capable of reaching greater altitude were developed, but although this made them immune from attack it made their bombing accuracy even worse. Countermeasures by the British included sound detection equipment, searchlights and anti-aircraft artillery, followed by night fighters in 1915. One tactic used early in the war, when their limited range meant the airships had to fly from forward bases and the only zeppelin production facilities were in Friedrichshafen, was the bombing of airship sheds by the British Royal Naval Air Service. Later in the war, the development of the aircraft carrier led to the first successful carrier-based air strike in history: on the morning of 19 July 1918, seven Sopwith 2F.1 Camels were launched from and struck the airship base at Tønder, destroying zeppelins L 54 and L 60.Robinson (1994), pp. 340–341. View from a French dirigible approaching a ship in 1918. Wreckage of Zeppelin L31 or L32 shot down over England 23 Sept 1916.
