The "head shadow" effect refers to the way sound waves are affected by the shape and position of a person's head, creating a phenomenon that influences how we perceive the direction of sounds. When sound waves travel toward a listener, the head can block certain frequencies or reduce the intensity of sound coming from one side compared to the other. This results in a difference in sound intensity and timing between the ears, which the brain interprets to locate the sound source.
Macrosonics is a term that refers to the use of very low-frequency sound waves, typically below the range of human hearing (20 Hz), for various applications. This technology is often explored in fields such as medicine, engineering, and environmental science. In medicine, macrosonics can be utilized for therapeutic purposes, such as in ultrasound treatments or non-invasive procedures that target tissues without causing damage. In engineering, it can be applied for material testing and analysis.
The noise floor refers to the level of background noise in a system or environment that can affect the performance and clarity of signals being processed or transmitted. It is an important concept in various fields, including telecommunications, audio engineering, and electronics. Here are some key points about the noise floor: 1. **Definition**: The noise floor is the measure of the sum of all unwanted signals (noise) within a given bandwidth, typically expressed in decibels (dB).
A radio noise source is a device or system designed to generate random electromagnetic noise across a certain frequency range, typically within the radio frequency (RF) spectrum. This noise can serve various purposes in telecommunications, electronics, and research. Here are some key points about radio noise sources: 1. **Types of Noise**: The noise created by such sources can include thermal noise, shot noise, and flicker noise, among others. Each type has unique characteristics and can be useful for different applications.
Time Gain Compensation (TGC) is a technique used primarily in radar and sonar systems, as well as in imaging and acoustic applications, to enhance the quality of the received signals. The purpose of TGC is to compensate for the loss of signal strength due to signal attenuation as the signal travels through a medium (like water or air) or as it propagates over distance.
The term **epitranscriptome** refers to the complete set of chemical modifications of RNA molecules present within a cell, tissue, or organism. It encompasses various post-transcriptional modifications that can occur on RNA, similar to how the term **epigenome** relates to modifications on DNA. Key aspects of the epitranscriptome include: 1. **Chemical Modifications**: RNA can undergo several types of modifications, such as methylation (e.g.

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
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.
