1
There are several different types of noise and they're categorized by color.
2
The most common are white, pink, and brown noise, each defined by the way it distributes power to frequencies across the audible spectrum.
3
Here's what that means.
4
White noise distributes power to every frequency equally, but it tends to sound harsh to us
5
because the shape of our ears makes us more sensitive to higher frequencies than lower ones, and that makes them sound louder, even though the power distribution is equal.
6
Pink noise adjusts for this.
7
boosting the harder to hear low frequencies, and then reducing power proportionally as frequency goes up, to give each octave of noise approximately equal energy.
8
This ends up sounding more balanced to our ears, even though it's actually skewed.
9
Brown noise takes this idea even further, resulting in a low, ocean -like rumble that a lot of people find relaxing.

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법
쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
