Aircraft noise reduction refers to the various methods and technologies employed to decrease the noise produced by aircraft during takeoff, flight, and landing. Noise from aircraft can impact communities near airports and contribute to environmental noise pollution. As a result, effective noise reduction strategies are crucial for enhancing the quality of life for nearby residents and meeting regulatory requirements. Key strategies for aircraft noise reduction include: 1. **Aircraft Design Improvements**: Newer aircraft models are often designed with quieter engines and aerodynamics that minimize noise.
Adaptive noise cancelling (ANC) is a technology used to reduce or eliminate unwanted ambient sound, primarily in audio applications such as headphones, earbuds, and hearing aids. Unlike passive noise cancellation, which relies on physical barriers to block sound, ANC actively counteracts noise using electronic methods. Here's how it generally works: 1. **Microphone Input**: ANC systems are equipped with microphones that pick up the ambient noise in the environment.

The specific definition and context can vary depending on the setting: 1. **Urban Planning**: In cities, quiet areas may be zones specifically set aside to reduce noise pollution from roads, construction, or other urban activities. These areas might be designated for residential purposes, parks, or natural preserves.
A silent disco is a unique dance party concept where attendees listen to music through wireless headphones instead of a traditional sound system. At a silent disco, multiple DJs can play different music simultaneously, allowing participants to choose their preferred channel and switch between them as they wish. This creates an individual listening experience while still fostering a communal atmosphere. Key features of a silent disco include: 1. **Headphones**: Guests wear wireless headphones equipped with adjustable volume controls and the option to switch between different music channels.
The Fresnel (symbol: F) is a unit of measurement used in optics to express the amount of light reflected or transmitted at an optical boundary, such as the interface between two media with different refractive indices. More specifically, it is often associated with the Fresnel equations, which describe how light behaves when it encounters an interface between two different media, providing the reflection and transmission coefficients for the light wave.

Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
