This distance, called critical distance d < sub > c </ sub >, can be specified as a function of room volume and reverberation time using Sabine's approximation:

Due to public demand, it was actually published on their return to Britain – much to Sabine's surprise.

Attempts to do this had been made in the eighteenth century, but it was not until Sabine's lifetime that precision instruments were available to allow sufficiently accurate measurements to be made.

Sabine's appointment was violently attacked by Charles Babbage, the father of the computer, ( largely on account of his associations with the Royal Society, whose scientific credentials Babbage did not recognise ) in a pamphlet entitled Reflections on the Decline of Science in England, and on Some of its Causes.

The result was Sabine's magnum opus: as complete a magnetic survey of the globe as was then humanly possible.

The first was soon after the Committee's formation, in 1963, when 16 species were removed: Red-crested Pochard, Snow Goose, Pectoral Sandpiper, Mediterranean Gull, Sabine's Gull, Melodious Warbler, Icterine Warbler, Yellow-browed Warbler, Northern Goshawk, Golden Eagle, Red Kite, Kentish Plover, Crested Tit, Bearded Tit, Marsh Warbler and Dartford Warbler.

Two branches of Sabine's work are notable: Determination of the length of the seconds pendulum, a simple pendulum whose time period on the surface of the Earth is two seconds, that is, one second in each direction ; and his research on the Earth's magnetic field.

While most of his research bears on the subjects just mentioned, other research deals with the birds of Greenland ( Sabine's Gull is named for him ), ocean temperatures, the Gulf Stream, barometric measurement of heights, arc of the meridian, glacial transport of rocks, the volcanoes of the Hawaiian Islands, and various points of meteorology.

The results of Sabine's magnetic researches were published in the Philosophical Transactions of the Royal Society.

In 1879 Sabine's wife, Elizabeth Leeves, died.

The tails of all but three species are rounded ; the exceptions being the Sabine's Gull and Swallow-tailed Gulls, which have forked tails, and the Ross's Gull, which has a wedge-shaped tail.

The Sabine's Gull is a small gull.

Occasionally individual Sabine's Gulls can be seen off other coasts such as the northeastern United States or further east in Europe, typically following autumn storms.

The Sabine's Gull breeds in colonies on coasts and tundra, laying two or three spotted olive-brown eggs in a ground nest lined with grass.

The Sabine's Gull is usually treated as comprising a monotypic genus, it is only placed within the genus Larus when the genus is enlarged.

Mitochondrial DNA studies confirmed this, and the closest relative of the Sabine's Gull is now thought to be the Ivory Gull, another Arctic species.

The Sabine's Gull is a small gull, in length and weighing.

This gull is traditionally believed to be most closely related to either the kittiwakes, Sabine's Gull, or Ross's Gull.

Structurally, it is most similar to the kittiwakes ; however, recent genetic analysis based on mtDNA sequences shows that Sabine's Gull is the Ivory Gull's closest relative, followed by the kittiwakes, with Ross's Gull and Swallow-tailed Gull sharing a clade with these species.

It is especially well known for its bird-life and over 200 species have been recorded at Ogston including Wilson's Phalarope, Sabine's Gull and Long-tailed Skuas.

On January 14, 1986, Balavoine, Sabine, a female reporter and her cameraman got aboard Sabine's Chopper to attend a football match.

The news of Sabine's and Balavoine's deaths plunged the country in deep grief, and the accident remains unexplained today.

It is while supervising this project that he died tragically in the crash of Sabine's Ecureuil in Mali.

Sabine's younger sister, Carmen, is also a professional tennis player.

The reverberation time RT < sub > 60 </ sub > and the volume V of the room have great influence on the critical distance d < sub > c </ sub > ( conditional equation ):

An attempt to provide for the reproduction of the reverberation was tried in the 1970s through quadraphonic sound but, again, the technology at that time was insufficient for the task.

The stage was altered acoustically with double plywood semi-circular partitions that separated the orchestra into five sections to increase reverberation.

Kevin Bowyer recorded Kaikhosru Sorabji's First Organ Symphony on it in 1988, for which the organ was an " ideal choice "; the notes to the recording describe the church as " acoustically ideal, with a reverberation period of 3½ seconds ", and notes that the organ has " a luxuriousness of tone " and " a range of volume from practically inaudible to fiendishly loud ".

The signature sound was characterized by a modulated (" granulized ") bassline, notable sidechain techniques, minimalist hitting and a heavy amount of reverberation used on either riffs or robotic voices.

The distinctive reverberation on the early hit records by Bill Haley & His Comets was created by recording the band under the domed ceiling of Decca's studio in New York, located in a former ballroom called The Pythian Temple.

In 2001, a 6000-pipe symphony organ was installed, designed and built by Johannes Klais Orgelbau in Bonn and specially tailored to the hall's reverberation chambers.

To increase reverberation, the stage was altered acoustically with five double plywood partitions that separated the sections of the orchestra.

He described hearing three shots that came from either the Depository on his left or near the mouth of the Triple Underpass railroad bridge on his right ; he was unsure because of the reverberation from the shots.

Another test was carried out in a room with a reverberation time of 1. 6 ms.

In the late 1960s it was reconstructed to solve acoustic problems of reverberation.

The pre-delay reverberation technique, recorded in part by Manning on the tracking session, had been used at Artie Fields productions in Detroit in late 1950s, and at Columbia Records ; it was also used by Wolfrum and others for numerous productions and commercials previous and after the release of this project including the Marvin Gaye What's Going On project, with orchestration also recorded at United.

The effect was very basic: a few low-grade inputs with only equalisation and reverberation to manipulate.

Historically, and implied by the word Opinion in its name, MOS was a subjective measurement where listeners would sit in a " quiet room " and score call quality as they perceived it ; per ITU-T recommendation P. 800, " The talker should be seated in a quiet room with volume between 30 and 120 m < sup > 3 </ sup > and a reverberation

Putnam was the first person in the US to use artificial reverberation using echo chambers for commercial recording ( the BBC's Broadcast House Studio in Savoy Hill, London, used for both broadcasting and commercial recording, being the first anywhere to use purpose made echo chambers with both echo send and returns and cue sends and multi-band EQ, and recording to disc and tape as early as 1931.

An onsite reverberation chamber tuned with fiberglass panels for the specific acoustical configuration was combined with the first commercial use of a digital delay line, the Lexicon DD1, then fed to the side and overhead speakers.

At that time the store area was reduced to three floors and additional panes of glass were put around the Grand Court on floors four and five, greatly enhancing the reverberation of the room.

The only known previous example was the Mormon Tabernacle where, it was said that one could hear a pin drop from the stage to the top balcony, although the chamber suffered from excess reverberation.

Just a few months later, in 1932, the PB-31 was replaced by the 44A, which was enormously successful and highly regarded for its smooth tone and defined pattern control, which not only reduced the effects of reverberation on soundstages, but also offered higher gain before feedback in live sound applications.

Ladytron's mix of " Like Eating Glass " replaces the lead and rhythm guitars with looped synthesisers and adds a large amount of reverberation to the vocals ; the resulting effect was described by Pitchfork Media's Nitsuh Adebe as " walking out of your apartment and thinking you can hear Bloc Party playing a festival six blocks over ".
