Raymond Carhart

Raymond Carhart is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Raymond Carhart rather than just read about it. In short: Raymond Theodore Carhart (March 28, 1912 - October 2, 1975) was a Speech-Language Pathologist (SLP). As a founder and pioneer of the science, he is frequently referred to as the "Father of Audiology." Early life and education Carhart was born on March 28, 1912, in Mexico City to Raymond Albert and Edith (Noble) Carhart.

Key takeaways

Raymond Carhart belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Raymond Carhart to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Raymond Carhart from memory before moving on to harder problems.

Reference excerpt

Early life and education Carhart was born on March 28, 1912, in Mexico City to Raymond Albert and Edith (Noble) Carhart. Raymond Albert was a Methodist missionary whose own father, Albert Elijah Carhart, was a temperance preacher. Carhart studied at Dakota Wesleyan University (BA in Speech and Psychology, 1932) and at Northwestern University (MA, 1934, and PhD, 1936, in Speech Pathology, Experimental Phonetics and Psychology).

Research and career Carhart remained at Northwestern until 1944, first as instructor in Speech Re-education and later as Assistant (1940) and Associate (1943) Professor. He joined the US Army Medical Administrative Corps in 1944, working in Butler, Pennsylvania until 1946. He returned to Northwestern in 1947, where he remained until his death in 1975.

Carhart notch Carhart notch effect is a decrease in the bone-conduction hearing at the 2000 Hz region of patients with otosclerosis first reported by and therefore named after Raymond Carhart.

Worked examples

Example 1 — a first encounter with Raymond Carhart

Start with the simplest possible case. Write down what Raymond Carhart claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Raymond Carhart before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Raymond Carhart ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Raymond Carhart

In research: Raymond Carhart appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Raymond Carhart in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Raymond Carhart is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1912 births, 1975 deaths, Audiologists, so understanding it makes those chapters shorter.
In everyday life: Look for Raymond Carhart outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
