Reference excerpt

A karaoke box (カラオケボックス, karaoke bokkusu) is a type of karaoke establishment commonly found in Asia, the United States and Canada. It originated in Japan, and is now popular worldwide, particularly in Asia. Karaoke boxes consist of multiple rooms containing karaoke equipment, usually rented out for a period of time. A typical karaoke box establishment contains 10–20 (or more) such rooms, that can be themed so that each room has a different feeling or can be a traditional karaoke box, as well as have a main karaoke bar area in the front. Karaoke box establishments often sell beverages, and sometimes food, but sometimes the establishment offers free refreshments. Many people of all ages enjoy karaoke as a pastime in Japan, as it still has a significant influence in the Japanese music scene and tourists are attracted to it as well. While people visit and enjoy karaoke boxes with family and friends, people also go by themselves and are able to enjoy the comfort of performing in the room by themselves. There is also a different style of karaoke, the traditional type where the patrons sing in front of everyone, that is also still offered in popular entertainment areas.

A new style of karaoke booth has appeared in Chinese shopping malls; customers can enter a booth, similar to a photo-booth, that allows them to perform different songs. It is suitable for use by one or two people. The booths are cheaper than the traditional karaoke box, as customers do not have to rent a room but just go in and sing a number of songs. The booths are very similar to the karaoke boxes but on a more intimate scale, with at least 20,000 booths running with an estimated CN¥3.18 billion (US$477 million) in 2017. The booths have an air conditioner, seats for the customers, the karaoke equipment, and headsets. Another recent trend is offering boxes for daytime meetings for businesses who need a cheap business room. There has also been conversation about fire safety with karaoke boxes after an arson in Hong Kong which led to public concern about their safety. One test recreated an establishment with three boxes and a corridor, in a remote location in China, with the intention of testing a real-time fire in a karaoke establishment. There has also been additional research about karaoke boxes as to ensure the safety of the customers in evacuation research about widening the length of hallways. The term karaoke box is primarily used in Japan, Hong Kong and Macau. Karaoke box establishments are commonly known as KTV (an abbreviation of karaoke television) in Taiwan, China, Cambodia, Myanmar, Singapore, the United States and Canada, videoke in the Philippines, noraebang (노래방) in South Korea (literally meaning singing room), hwamyŏn panju ŭmaksil (화면반주음악실) in North Korea (literally meaning screen accompaniment music room), karaoke room in Vietnam, and karaoke club in Sri Lanka. It is also common to simply abbreviate it as K in Hong Kong Cantonese, often when used as a verb, for example 去K歌 (to go K songs) or 去唱K (to go sing K).

Worked examples

Example 1 — a first encounter with Karaoke box

Start with the simplest possible case. Write down what Karaoke box claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Karaoke box 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 Karaoke box 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 Karaoke box

In research: Karaoke box appears in science 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 Karaoke box 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: Karaoke box is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cantonese culture, Chinese culture, Culture of Cambodia, so understanding it makes those chapters shorter.
In everyday life: Look for Karaoke box 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.
