브라운 노이즈 생성기

가장 깊은 노이즈. 브라운 노이즈는 옥타브마다 6dB씩 줄어 에너지 거의 전부가 저음에 삽니다. 먼 폭포, 비행기의 웅웅거림, 거센 바람 같은 소리. 쉭쉭거림 없는 저음입니다. 백색소음이 날카롭다고 느끼는 사람들의 최애.

브라운 노이즈란?

브라운(레드라고도 함) 노이즈는 옥타브마다 파워가 6dB씩 떨어지는 신호로, 핑크의 두 배 기울기입니다. 이름은 색이 아니라 브라운 운동에서 왔습니다. 수학적으로는 그 소리 자취, 즉 백색소음의 적분입니다.

귀에는 거의 모든 것이 아래쪽에 몰립니다. 웅웅거림, 우르릉, 먼 천둥. 고음이 워낙 적어 쉭쉭거림이 사실상 없고, 그래서 상당한 음량으로도 몇 시간이고 듣기가 가장 편합니다.

수면과 작업을 위한 깊은 배경

브라운 노이즈는 ADHD가 있는 사람들 사이에서 하나의 현상이 되었습니다. 낮고 일정한 울림이 머릿속 소음을 "꺼 주고" 집중을 가능하게 한다는 경험담이 수천 건입니다. 엄밀한 임상 연구는 아직 적으니 위험 없는 무료 실험으로 여기세요. 많은 이들이 그대로 정착합니다.

말소리 마스킹에는 백색보다 약합니다. 음성 주파수 대역의 에너지가 적기 때문이죠. 대화를 덮으려면 백색이나 핑크부터, 부드럽게 감싸는 배경을 원하면 브라운이 무적입니다. 주의: 노트북 스피커는 저음을 거의 재생하지 못합니다. 헤드폰이나 제대로 된 스피커로 들으세요.

브라운 노이즈 자주 묻는 질문

백색·핑크와의 차이는?

스펙트럼 기울기입니다. 백색 = 옥타브당 0dB(밝음), 핑크 = −3dB(균형), 브라운 = −6dB(깊고 어두움). 기울기가 가파를수록 쉭쉭거림은 줄고 저음은 늘어납니다.

ADHD에 효과가 있나요?

경험담은 많고 놀랄 만큼 한결같이 긍정적이지만, 브라운 노이즈만을 대상으로 한 통제 연구는 아직 부족합니다. 기제는 그럴듯합니다: 일정한 배경음이 자극 추구를 줄이고 방해 요소를 가립니다. 직접 시험해 보세요. 무료에 위험도 없습니다.

노트북에서 거의 안 들리는 이유는?

주 에너지가 200Hz 아래에 있는데 작은 스피커는 그 주파수를 물리적으로 재생하지 못하기 때문입니다. 남는 건 고음의 희미한 잔재뿐. 헤드폰이나 제대로 된 스피커라야 전모가 드러납니다.

밤새 틀고 자도 되나요?

네. 적당한 음량이라면 안전하며, 규칙은 다른 배경음과 같습니다: 필요 최소 음량, 편안함 우선. 깊은 배경음 덕에 갑작스러운 소리에 덜 깨는 사람도 많습니다.
