Noise-cancelling Headphones
Noise-cancelling headphones are headphones that suppress unwanted ambient sounds using active noise control (ANC). Active noise cancellation makes it possible to listen to audio content without raising the volume excessively. In an aviation environment, noise-cancelling headphones increase the signal-to-noise ratio significantly more than passive noise attenuating headphones or no headphones, making hearing important information such as safety announcements easier. Noise-cancelling headphones can improve listening enough to completely offset the effect of a distracting concurrent activity. Theory To cancel the lower-frequency portions of the noise, noise-cancelling headphones use active noise control. A microphone captures the targeted ambient sounds, and a small amplifier generates sound waves that are exactly out of phase with the undesired sounds. When the sound pressure of the noise wave is high, the cancelling wave is low (and vice versa). The opposite sound waves collide ...

ADHD
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterised by symptoms of inattention, hyperactivity, impulsivity, and emotional dysregulation that are excessive and pervasive, impairing in multiple contexts, and developmentally inappropriate. ADHD symptoms arise from executive dysfunction. Impairments resulting from deficits in self-regulation such as time management, inhibition, task initiation, and sustained attention can include poor professional performance, relationship difficulties, and numerous health risks, collectively predisposing to a diminished quality of life and a reduction in life expectancy. As a consequence, the disorder costs society hundreds of billions of US dollars each year, worldwide. It is associated with other mental disorders as well as non-psychiatric disorders, which can cause additional impairment. While ADHD involves a lack of sustained attention to tasks, inhibitory deficits also can lead to diffic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autistic People
Autism, also known as autism spectrum disorder (ASD), is a neurodevelopmental disorder characterized by differences or difficulties in social communication and interaction, a preference for predictability and routine, sensory processing differences, focused interests, and repetitive behaviors, which may include stimming. Formal diagnosis requires significant challenges in multiple domains of life, with characteristics that are atypical or more pronounced than expected for one's age and sociocultural context.(World Health Organization: International Classification of Diseases version 11 (ICD-11)): https://icd.who.int/browse/2024-01/mms/en#437815624 Motor coordination difficulties are common but not required for diagnosis. Autism is a spectrum disorder, resulting in wide variations in presentation and support needs, such as that between speaking and non-speaking populations. Increased estimates of autism prevalence since the 1990s are primarily attributed to broader crite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neurodivergent
The neurodiversity paradigm is a framework for understanding human brain function that considers the diversity within sensory processing, motor abilities, social comfort, cognition Cognition is the "mental action or process of acquiring knowledge and understanding through thought, experience, and the senses". It encompasses all aspects of intellectual functions and processes such as: perception, attention, thought, ..., and Attention, focus as neurobiological differences. This diversity falls on a spectrum of neurocognitive differences. The neurodiversity paradigm argues that diversity in neurocognition is part of humanity and that some neurodivergences generally classified as disorders, such as autism, are differences with strengths and weaknesses as well as disabilities that are not necessarily Medical model of disability, pathological. The neurodiversity movement started in the late 1980s and early 1990s with the start of Autism Network International. Much of th ...

Insomnia
Insomnia, also known as sleeplessness, is a sleep disorder where people have difficulty sleeping. They may have difficulty falling asleep, or staying asleep for as long as desired. Insomnia is typically followed by daytime sleepiness, low energy, irritability, and a depression (mood), depressed mood. It may result in an increased risk of accidents of all kinds as well as problems focusing and learning. Insomnia can be short term, lasting for days or weeks, or long term, lasting more than a month. The concept of the word ''insomnia'' has two distinct possibilities: insomnia disorder (ID) or insomnia symptoms, and many abstracts of randomized controlled trials and systematic reviews often underreport on which of these two possibilities the word refers to. Insomnia can occur independently or as a result of another problem. Conditions that can result in insomnia include psychological stress, chronic pain, heart failure, hyperthyroidism, heartburn, restless leg syndrome, menopause ...

Earplug
An earplug is a device that is inserted in the ear canal to protect the user's ears from loud noises, intrusion of water, foreign bodies, dust or excessive wind. Earplugs may be used as well to improve sleep quality or focus in noisy environments. Since they reduce the sound volume, earplugs may prevent hearing loss and tinnitus (ringing of the ears), in some cases. US Occupational Safety and Health Administration requires hearing conservation programs which include the provision of hearing protection devices (HPDs). But this does not mean that OSHA considers HPDs to be effective. History The first recorded mention of the use of earplugs is in the Greek tale ''Odyssey,'' wherein Odysseus's crew is warned about the Siren (mythology), Sirens that sing from an island they will sail past. Circe, their hostess, tells them of the Sirens' bewitching song that makes men drive their boats ashore and perish. She advised Odysseus to fashion earplugs for his men from beeswax so they would n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Class (aviation)
First class (also sometimes branded as a suite) is a travel class on some Airliner, passenger airliners intended to be more luxurious than business class, premium economy, and economy class. Originally, all planes offered only one class of service (often equivalent to the modern business or economy class), with a second class appearing first in 1955 when Trans World Airlines, TWA introduced two different types of service on its Lockheed L-1049 Super Constellation, Super Constellations. On a passenger jetliner, ''first class'' usually refers to a limited number (rarely more than 10) of seats or Aircraft cabin, cabins toward the front of the aircraft which have more space and comfort, including better service and increased privacy. In general, first class is the highest class offered, although some airlines have either branded their new products as above first class or offered business class as the highest class. Propeller airliners often had first class in the rear, away from the no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Business Class
Business class is a travel class available on many commercial airlines and rail lines, known by brand names that vary by airline or rail company. In the airline industry, it was originally intended as an intermediate level of service between economy class and first class, but many airlines now offer business class as the highest level of service, having eliminated first class seating. Business class is distinguished from other travel classes by the quality of seating, food, drinks, ground service and other amenities. In commercial aviation, full business class is usually denoted 'J' or 'C' with schedule flexibility, but can be many other letters depending on circumstances. Airlines History Airlines began separating full-fare and discounted economy-class passengers in the late 1970s. In 1976, KLM introduced a Full Fare Facilities (FFF) service for its full fare economy-class passengers, which allowed them to sit at the front of the economy cabin immediately behind first clas ...
