白噪音、粉红噪音和棕噪音有什么区别?
白噪音更明亮,能量在各频率间均匀分布;粉红噪音和棕噪音依次减少高频,因此听感更柔和、更低沉。
选择听起来最舒适的噪音颜色,保持低音量,为睡前、专注或需要安静的房间提供稳定背景。
White noise spreads energy evenly across the audible spectrum, producing a bright, consistent hiss that can cover sudden environmental sounds.
Pink and brown noise reduce higher frequencies progressively, creating softer and deeper tones. Grey noise is shaped to feel more even to human hearing. Preference matters more than choosing one universally best color.
Start at a low volume and raise it only enough to make intermittent background sounds less noticeable. The goal is a stable backdrop, not a loud foreground sound.
Use the timer when you want the sound to fade from your routine after you settle. Stop listening if the volume feels uncomfortable or leaves your ears ringing.

没有适合所有人的最佳颜色。如果觉得白噪音刺耳,可先试粉红或棕噪音,再选择低音量下听起来舒适的那一种。
成年人可使用舒适的低音量,但整夜播放并非必要。希望安定下来后停止时,请使用定时功能。
