The annual extreme temperatures range from −29.1 °C (−20.4 °F) on 13 February 1940, to 40.1 °C (104.2 °F) on 20 July 2022 , and

9028-493: The central nervous system is activated by basic acoustical characteristics of music. By observing how the central nervous system, which includes the brain and spine, is influenced by acoustics, the pathway in which acoustic affects the mind, and essentially the body, is evident. Acousticians study the production, processing and perception of speech. Speech recognition and Speech synthesis are two important areas of speech processing using computers. The subject also overlaps with

9150-563: The city and the harbour. On 23 July 1943, the Royal Air Force and United States Army Air Force firebombing created a firestorm which spread from the Hauptbahnhof (main railway station) and quickly moved south-east, completely destroying entire boroughs such as Hammerbrook , Billbrook and Hamm South . Thousands of people perished in these densely populated working class boroughs. The raids, codenamed Operation Gomorrah by

9272-453: The city from most of its hinterland and reduced Hamburg's global trade. Since German reunification in 1990, and the accession of several Central European and Baltic countries into the European Union in 2004, the Port of Hamburg has restarted ambitions for regaining its position as the region's largest deep-sea port for container shipping and its major commercial and trading centre. Hamburg

9394-571: The city with the highest number of bridges in Europe, and with 5 of the world's 29 tallest churches standing in Hamburg , it is also the city with the highest number of churches surpassing 100 metres (330 ft) worldwide. Aside from its rich architectural heritage, the city is also home to notable cultural venues such as the Elbphilharmonie and Laeiszhalle concert halls. It gave birth to movements like Hamburger Schule and paved

9516-608: The coalition broke apart on 28 November 2010. On 7 March 2011 Olaf Scholz ( SPD ) became mayor. After the 2015 election the SPD and the Alliance 90/The Greens formed a coalition. Hamburg is made up of seven boroughs (German: Bezirke ) and subdivided into 104 quarters (German: Stadtteile ). There are 181 localities (German: Ortsteile ). The urban organisation is regulated by the Constitution of Hamburg and several laws. Most of

9638-438: The complete laws of vibrating strings (completing what Pythagoras and Pythagoreans had started 2000 years earlier). Galileo wrote "Waves are produced by the vibrations of a sonorous body, which spread through the air, bringing to the tympanum of the ear a stimulus which the mind interprets as sound", a remarkable statement that points to the beginnings of physiological and psychological acoustics. Experimental measurements of

9760-644: The construction of four vessels in the port. The Caledonia , a ship of 600 tons with 56 guns, and the Instuaration (later renamed the St. Andrew ), a vessel of 350 tons, were launched in March 1697. Upon the dissolution of the Holy Roman Empire in 1806, the Free Imperial City of Hamburg was not incorporated into a larger administrative area while retaining special privileges ( mediatised ), but became

9882-437: The course of the years, however, many different clubs and societies have been formed, to enable leisure activities without clashing with study obligations. One large event in the academic year is the "TAF ("Trimesteranfangsfeier" or "Start of term ceremony"). This takes place annually to greet the new students. It is organized by the members of the "Studentischer Konvent" and enjoys widespread popularity. The Studentischer Konvent

10004-501: The courses comply with the requirements of Hamburg's higher education legislation. The university is authorised to confer habilitations and doctoral degrees . On 11 June 1970, the Federal Minister of Defense at the time, Helmut Schmidt , for whom the university was later named and who later would become chancellor of Germany, published a decree that a university be established for the purpose of schooling certain members of

10126-536: The decree for the university's establishment. The idea of a university is his brainchild. Schmidt was present at the ceremony and was awarded an honorary degree. At the Helmut Schmidt University there is a specific organizational structure, in addition to the division between the areas of teaching and administration that is common to all universities, there is a military side, to accommodate the HSU's dual function as an educational establishment and

10248-536: The disciplines of physics, physiology , psychology , and linguistics . Structural acoustics is the study of motions and interactions of mechanical systems with their environments and the methods of their measurement, analysis, and control. There are several sub-disciplines found within this regime: Applications might include: ground vibrations from railways; vibration isolation to reduce vibration in operating theatres; studying how vibration can damage health ( vibration white finger ); vibration control to protect

10370-584: The emphasis is on logistics, business administration and economics, and political science. Gender topics have also been researched for years. The HSU is designed as a campus university, and its campus in the Wandsbek district consists of 3 parts. Studying activities take place on the premises of the former Douaumont barracks on the Holstenhofweg in Hamburg-Jenfeld. The university administration

10492-540: The first constitution of Hamburg . In 1356, the Matthiae-Mahl feast dinner for Hanseatic League cities was celebrated for the first time on 25 February, the first day of spring in medieval times. It continues today as the world's oldest ceremonial meal. In 1529, the city embraced Lutheranism , and it received Reformed refugees from the Netherlands and France. When Jan van Valckenborgh introduced

10614-456: The first World War. Sound recording and the telephone played important roles in a global transformation of society. Sound measurement and analysis reached new levels of accuracy and sophistication through the use of electronics and computing. The ultrasonic frequency range enabled wholly new kinds of application in medicine and industry. New kinds of transducers (generators and receivers of acoustic energy) were invented and put to use. Acoustics

10736-633: The focus is on the areas of professional and organizational education, adult education and history. The establishment of a uniform German Qualifications Framework in the context of the European Qualifications Framework may be traced back in no small part to the work of the professor for professional and organizational education in the working group of the Federal Ministry for Education and Research, through expert advice and support. In economic and management sciences,

10858-455: The historical origin of Hamburg. Acoustics Hearing is one of the most crucial means of survival in the animal world and speech is one of the most distinctive characteristics of human development and culture. Accordingly, the science of acoustics spreads across many facets of human society—music, medicine, architecture, industrial production, warfare and more. Likewise, animal species such as songbirds and frogs use sound and hearing as

10980-583: The latest territorial reform of March 2008, the boroughs are Hamburg-Mitte , Altona , Eimsbüttel , Hamburg-Nord , Wandsbek , Bergedorf , and Harburg .

View climate chart 1986–2016 or 1960–1990 On 31 December 2016, there were 1,860,759 people registered as living in Hamburg in an area of 755.3 km (291.6 sq mi). The population density was 2,464/km (6,380/sq mi). The metropolitan area of

11224-520: The main trade routes of the North Sea and Baltic Sea , quickly made it a major port in Northern Europe. Its trade alliance with Lübeck in 1241 marks the origin and core of the powerful Hanseatic League of trading cities. On 8 November 1266, a contract between Henry III and Hamburg's traders allowed them to establish a hanse in London. This was the first time in history that the word hanse

11346-605: The more desirable, harmonious notes. During the Islamic golden age , Abū Rayhān al-Bīrūnī (973–1048) is believed to have postulated that the speed of sound was much slower than the speed of light. The physical understanding of acoustical processes advanced rapidly during and after the Scientific Revolution . Mainly Galileo Galilei (1564–1642) but also Marin Mersenne (1588–1648), independently, discovered

11468-450: The navy (German: Marine), B battalion by a member of the air force (German: Luftwaffe) and C battalion by a member of the army (German: Heer). They usually also hold the title of Senior Branch Officer (i.e. Senior Naval/Air Force/Army Officer on Campus). Each battalion consists of several companies (German: "Studierendenfachbereichsgruppen", short: StudFBerGrp, lit.: "student subject area groups"), commandend by an army or air force captain or

11590-513: The office of the mayor, the meeting room for the Senate and the floor for the Hamburg Parliament . From 2001 until 2010, the mayor of Hamburg was Ole von Beust , who governed in Germany's first statewide "black-green" coalition, consisting of the conservative CDU Hamburg and the alternative GAL, which are Hamburg's regional wing of the Alliance 90/The Greens party. Von Beust was briefly succeeded by Christoph Ahlhaus in 2010, but

11712-1068: The population belonged to the North Elbian Evangelical Lutheran Church , the largest religious body, and 9.9% to the Roman Catholic Church . Hamburg is seat of one of the three bishops of the Evangelical Lutheran Church in Northern Germany and seat of the Roman Catholic Archdiocese of Hamburg . According to the publication Muslimisches Leben in Deutschland (" Muslim life in Germany "), an estimated 141,900 Muslim migrants (from nearly 50 countries of origin) lived in Hamburg in 2008. About three years later (May 2011) calculations based on census data for 21 countries of origin resulted in

11834-578: The population in 1350. Hamburg experienced several great fires in the medieval period. In 1189, by imperial charter, Frederick I "Barbarossa" granted Hamburg the status of a Free Imperial City and tax-free access (or free-trade zone ) up the Lower Elbe into the North Sea. In 1265, an allegedly forged letter was presented to or by the Rath of Hamburg. This charter, along with Hamburg's proximity to

11956-406: The private flats, 2 to 3 students will be accommodated together. In principle, every student receives a single room with area of 14 to 20 m (151 to 215 sq ft), mostly with en-suite bathroom and toilet. During the time of higher than usual student numbers however, there will inevitably be some instances where 2 students share a larger room. Residents may cook in the shared kitchens, where

12078-406: The propagating medium. Eventually this energy is transduced again into other forms, in ways that again may be natural and/or volitionally contrived. The final effect may be purely physical or it may reach far into the biological or volitional domains. The five basic steps are found equally well whether we are talking about an earthquake , a submarine using sonar to locate its foe, or a band playing in

12200-469: The quarters were former independent cities, towns or villages annexed into Hamburg proper. The last large annexation was done through the Greater Hamburg Act of 1937, when the cities Altona , Harburg , and Wandsbek were merged into the state of Hamburg. The Act of the Constitution and Administration of Hanseatic city of Hamburg established Hamburg as a state and a municipality. Some of

12322-435: The relationship between acoustics and cognition , or more commonly known as psychoacoustics , in which what one hears is a combination of perception and biological aspects. The information intercepted by the passage of sound waves through the ear is understood and interpreted through the brain, emphasizing the connection between the mind and acoustics. Psychological changes have been seen as brain waves slow down or speed up as

12444-492: The requisite military training with that unit, before being posted to the university and completing the academic education there, which is a part of the training for becoming an officer. The educational requirement for attending the HSU is a general higher education entrance qualification that is recognized by the law on higher education of the Free and Hanseatic City of Hamburg. Prior to their studies, soldiers must train at one of

12566-437: The short length of revision time and the fact that all the exams are "en bloc", resits are greatly feared by the students, particularly the engineering students. Resit exams occur during the exam block of the next term, and in this way a "bow wave" of an ever-increasing number of exams to take can accumulate, which may be very difficult to remain on top of. The standard period of study for the master's degree (the standard degree)

12688-485: The social life between studies and the Hamburg night life will take place. Due to structural changes in military training, several external residences had to be acquired including the former Lettow-Vorbeck Barracks, which is now used by the Federal Police (Bundespolizei). Another facility frequented by students and staff is the casino , the officer's club of the HSU (not a gambling establishment), located opposite

12810-444: The sound wave strikes the microphone's diaphragm, it moves and induces a voltage change. The ultrasonic systems used in medical ultrasonography employ piezoelectric transducers. These are made from special ceramics in which mechanical vibrations and electrical fields are interlinked through a property of the material itself. An acoustician is an expert in the science of sound. There are many types of acoustician, but they usually have

12932-416: The student is likely to successfully complete his or her studies in the near future. After completion of one's studies, that is after one has submitted one's final dissertation, the officer will return to a post in the army or the fleet relatively quickly, according to availability of vacant posts, the officer's leave entitlement and course plans. The award of the study diplomas always occurs in mid-October in

13054-411: The students may settle into their accommodation and receive an introduction to studying at the HSU from the more advanced students. In contrast to the semester format usually practised in Germany, a year at the HSU is divided into 3 terms (trimesters) which means that it consists not of a winter and summer semester, but of autumn, winter and spring terms, 3 blocks of 3 months each. There are no classes in

13176-468: The study of speech intelligibility, speech privacy, music quality, and vibration reduction in the built environment. Commonly studied environments are hospitals, classrooms, dwellings, performance venues, recording and broadcasting studios. Focus considerations include room acoustics, airborne and impact transmission in building structures, airborne and structure-borne noise control, noise control of building systems and electroacoustic systems. Bioacoustics

13298-467: The summer quarter (1 July – 30 September). This period may be used for performing required periods of practical training and internships, and for holidays. Exams are taken at the end of every term, and test the material that was studied in that term. In a few cases, exams at the end of a term may concern the material of more than one term. For the purpose of revision, one or two weeks in mid-December, late March and late June may be devoid of classes. Due to

13420-959: The three respective Officer Training school: for the Army in Dresden /('OSH'), for the Air Force in Fürstenfeldbruck ('OSLw') and for the Navy in Flensburg ('MSM'). During their stay at the HSU, military personnel are required to complete certain standard procedures every year. These include: On occasion: 53°34′04″N 10°06′26″E  /  53.56778°N 10.10722°E  / 53.56778; 10.10722 Hamburg Hamburg ( German: [ˈhambʊʁk] , locally also [ˈhambʊɪ̯ç] ; Low Saxon : Hamborg [ˈhambɔːç] ), officially

13542-456: The time varying pressure level and frequency profiles which give a specific acoustic signal its defining character. A transducer is a device for converting one form of energy into another. In an electroacoustic context, this means converting sound energy into electrical energy (or vice versa). Electroacoustic transducers include loudspeakers , microphones , particle velocity sensors, hydrophones and sonar projectors. These devices convert

13664-420: The ultrasonic frequency range. On the other end of the spectrum, the lowest frequencies are known as the infrasonic range. These frequencies can be used to study geological phenomena such as earthquakes. Analytic instruments such as the spectrum analyzer facilitate visualization and measurement of acoustic signals and their properties. The spectrogram produced by such an instrument is a graphical display of

13786-589: The university. A prerequisite for studying as a civilian at the Helmut Schmidt University is a business scholarship. These scholarships are usually awarded by foundations with close relationships to industry – thus, these students are at least indirectly being supported by their future employer, usually large companies. As of 2022 tuition costs are currently 2941 euros (humanities), 4403 euros (economics) or 3423 euros (engineering) per academic term . Academic degrees and titles obtained at HSU are equivalent to those awarded by state universities and are equally valid, since

13908-500: The verb ἀκούω( akouo ), "I hear". The Latin synonym is "sonic", after which the term sonics used to be a synonym for acoustics and later a branch of acoustics. Frequencies above and below the audible range are called " ultrasonic " and " infrasonic ", respectively. In the 6th century BC, the ancient Greek philosopher Pythagoras wanted to know why some combinations of musical sounds seemed more beautiful than others, and he found answers in terms of numerical ratios representing

14030-416: The wave interacts with the environment. This interaction can be described as either a diffraction , interference or a reflection or a mix of the three. If several media are present, a refraction can also occur. Transduction processes are also of special importance to acoustics. In fluids such as air and water, sound waves propagate as disturbances in the ambient pressure level. While this disturbance

14152-641: The way for bands including the Beatles . Hamburg is also known for several theatres and a variety of musical shows. St. Pauli 's Reeperbahn is among the best-known European red light districts. Claudius Ptolemy (2nd century AD) reported the first name for the vicinity as Treva . The name Hamburg comes from the first permanent building on the site, a castle which the Emperor Charlemagne ordered constructed in AD 808. It rose on rocky terrain in

14274-509: The world's largest transatlantic shipping company around the start of the 20th century. Shipping companies sailing to South America, Africa, India and East Asia were based in the city. Hamburg was the departure port for many Germans and Eastern Europeans to emigrate to the United States in the late 19th and early 20th centuries. Trading communities from all over the world established themselves there. A major outbreak of cholera in 1892

14396-408: Was a range of such Missingsch varieties, the best-known being the low-prestige ones of the working classes and the somewhat more bourgeois Hanseatendeutsch (Hanseatic German), although the term is used in appreciation. All of these are now moribund due to the influences of Standard German used by education and media. However, the former importance of Low German is indicated by several songs, such as

14518-609: Was badly handled by the city government, which retained an unusual degree of independence for a German city. About 8,600 died in the largest German epidemic of the late 19th century, and the last major cholera epidemic in a major city of the Western world. Hamburg was a Gau within the administrative division of Nazi Germany from 1934 until 1945. During the Second World War , the Allied bombing of Hamburg devastated much of

14640-590: Was suggested by Portuguese residents to bring visibility to the Portuguese community in Hamburg. Hamburg's Afghan community of about 50,000 people is the largest not only in Germany, but also in Europe. They first came to Hamburg in the 1970s before expanding during the Afghan conflict in the 1980s and 1990s where many Afghan migrants chose to live in Hamburg. After 2015 the Afghan population almost doubled due to

14762-659: Was surrendered to British Forces on 3 May 1945, in the Battle of Hamburg , three days after Adolf Hitler 's death. After the Second World War , Hamburg formed part of the British Zone of Occupation ; it became a state of West Germany in 1949. On 16 February 1962, a North Sea flood caused the Elbe to rise to an all-time high, inundating one-fifth of Hamburg and killing more than 300 people. The inner German border – only 50 kilometres (30 mi) east of Hamburg – separated

14884-534: Was used for the trading guild of the Hanseatic League . In 1270, the solicitor of the senate of Hamburg , Jordan von Boitzenburg , wrote the first description of civil, criminal and procedural law for a city in Germany in the German language, the Ordeelbook ( Ordeel : sentence). On 10 August 1410, civil unrest forced a compromise (German: Rezeß , literally meaning: withdrawal). This is considered
