白噪音、粉红噪音、雨声为何能帮助专注与放松？本文解释掩蔽噪音的原理，给出番茄工作法与音效搭配的实操建议，帮你进入心流。
突然的、间歇性的环境噪音最容易打断注意力。白噪音/粉红噪音以平稳的频谱掩蔽突发声响，降低大脑被「惊动」的频率，从而营造更连续的专注背景。有人用它屏蔽办公室交谈、咖啡馆嘈杂或家人活动声。
以 25 分钟专注 + 5 分钟休息为一个循环，配合稳定的背景音效更容易进入状态。专注段用较中性的白/粉噪，休息段换成轻松的自然声，形成节奏暗示。每天 4–6 个循环，长休息 15–30 分钟。

因人而异。部分人更易被音乐分心，平稳噪音反而帮助专注；建议多档音量与类型试用找到适合自己的。
以能盖过突发杂音但不刺耳为准，一般中等偏低即可，长时间聆听尤其不宜过大。
合理音量、适当休息下通常无碍；避免长时间高分贝佩戴耳机。
Why do white/pink noise and rain sounds aid focus and relaxation? Learn the masking principle and practical Pomodoro pairings to reach flow — with free local tools.
Sudden, intermittent sounds break attention most. White/pink noise masks those spikes with a steady spectrum, so your brain gets startled less — a smoother backdrop for concentration against office chatter or café noise.
Run 25-minute focus sprints with 5-minute breaks; a steady soundscape eases you in. Use neutral white/pink noise during focus, switch to gentle nature sounds on breaks to cue the rhythm. Aim for 4–6 cycles with a longer 15–30 min break.
Mix and balance many sounds with Noise Mixer; keep the screen awake with Keep Awake for long reading; plan focus windows with Time Tools. All run locally in your browser, no uploads.
It varies — some get distracted by music and focus better with steady noise. Try levels and types to find yours.
Just enough to mask sudden noise without being harsh; keep it low-to-medium for long sessions.
At reasonable volume with breaks, generally fine; avoid long, loud headphone sessions.
