Ear Trumpet
An ear trumpet is a tubular or funnel-shaped device which collects sound waves and leads them into the ear. They were used as hearing aids, resulting in a strengthening of the sound energy impact to the eardrum and thus improved hearing for a deaf or hard-of-hearing individual. Ear trumpets were made of sheet metal, silver, wood, snail shells or animal horns. They have largely been replaced in wealthier areas of the world by modern hearing aid technology that is much smaller and less obtrusive, albeit more expensive. A sound trumpet does not "amplify" sound. It takes the sound power received over a large area and concentrates it into a smaller area. The received sound is louder, but no power has been created in the process. History The use of ear trumpets for the partially deaf dates back to the 17th century.Howard, Alexander.

Joshua Reynolds
Sir Joshua Reynolds (16 July 1723 – 23 February 1792) was an English painter, specialising in portraits. John Russell said he was one of the major European painters of the 18th century. He promoted the "Grand Style" in painting which depended on idealization of the imperfect. He was a founder and first president of the Royal Academy of Arts, and was knighted by George III in 1769. Early life Reynolds was born in Plympton, Devon, on 16 July 1723 the third son of the Rev. Samuel Reynolds, master of the Plympton Free Grammar School in the town. His father had been a fellow of Balliol College, Oxford, but did not send any of his sons to the university. One of his sisters was Mary Palmer (1716–1794), seven years his senior, author of ''Devonshire Dialogue'', whose fondness for drawing is said to have had much influence on him when a boy. In 1740 she provided £60, half of the premium paid to Thomas Hudson the portrait-painter, for Joshua's pupilage, and nine years later a ...

Midwife
A midwife is a health professional who cares for mothers and newborns around childbirth, a specialization known as midwifery. The education and training for a midwife concentrates extensively on the care of women throughout their lifespan; concentrating on being experts in what is normal and identifying conditions that need further evaluation. In most countries, midwives are recognized as skilled healthcare providers. Midwives are trained to recognize variations from the normal progress of labor and understand how to deal with deviations from normal. They may intervene in high risk situations such as breech births, twin births, and births where the baby is in a posterior position, using non-invasive techniques. For complications related to pregnancy and birth that are beyond the midwife's scope of practice, including surgical and instrumental deliveries, they refer their patients to physicians or surgeons. In many parts of the world, these professions work in tandem to provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stethoscope
The stethoscope is a medical device for auscultation, or listening to internal sounds of an animal or human body. It typically has a small disc-shaped resonator that is placed against the skin, and one or two tubes connected to two earpieces. A stethoscope can be used to listen to the sounds made by the heart, lungs or intestines, as well as blood flow in arteries and veins. In combination with a manual sphygmomanometer, it is commonly used when measuring blood pressure. Less commonly, "mechanic's stethoscopes", equipped with rod shaped chestpieces, are used to listen to internal sounds made by machines (for example, sounds and vibrations emitted by worn ball bearings), such as diagnosing a malfunctioning automobile engine by listening to the sounds of its internal parts. Stethoscopes can also be used to check scientific vacuum chambers for leaks and for various other small-scale acoustic monitoring tasks. A stethoscope that intensifies auscultatory sounds is called a phonen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinard Horn
A Pinard horn is a type of stethoscope used to listen to the heart rate of a fetus during pregnancy. It is a hollow horn, often made of wood or metal, about long. It functions similarly to an ear trumpet by amplifying sound. The user holds the wide end of the horn against the pregnant woman's abdomen, and listens through the other end. History The Pinard horn was invented by Dr. Adolphe Pinard, a French obstetrician, during the 19th century. Pinard was an early supporter of advancements in prenatal care, including closer fetal health monitoring. The invention came about in 1895. Current use Pinard horns continue to be used around the world, particularly by midwives, but also by doctors and nurses. It provides an alternative to the more expensive Doppler foetal monitor. Another alternative is the fetoscope, which is a stethoscope designed for auscultating fetuses. Below is a quote from a midwife in Mexico describing using the Pinard horn: A Pinard horn may be used to determin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ludwig Van Beethoven
Ludwig van Beethoven (baptised 17 December 177026 March 1827) was a German composer and pianist. Beethoven remains one of the most admired composers in the history of Western music; his works rank amongst the most performed of the classical music repertoire and span the transition from the Classical period to the Romantic era in classical music. His career has conventionally been divided into early, middle, and late periods. His early period, during which he forged his craft, is typically considered to have lasted until 1802. From 1802 to around 1812, his middle period showed an individual development from the styles of Joseph Haydn and Wolfgang Amadeus Mozart, and is sometimes characterized as heroic. During this time, he began to grow increasingly deaf. In his late period, from 1812 to 1827, he extended his innovations in musical form and expression. Beethoven was born in Bonn. His musical talent was obvious at an early age. He was initially harshly and intensively tau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
