风扇声等于白噪音吗？
风扇声包含宽频声音，但机械嗡鸣与经过过滤的音色，使它不像纯白噪音那样均匀。
睡前风扇声
不用让真实风扇一直运转，也能听熟悉的稳定风扇声。选择预设、调节音量，为睡前或专注工作设置定时。
睡前风扇声
四种熟悉的风扇声音
Box Fan is broad and steady, Desk Fan is lighter, Air Conditioner adds a lower mechanical bed, and Deep Fan emphasizes a softer low-frequency hum.
These generated profiles avoid short recording loops and continue until you stop them or the timer ends.
遮蔽房间里不规律的声音
A consistent fan-like sound can make traffic, hallway movement, or household changes feel less abrupt. Set it only as loud as needed to soften those changes.
The same steady background can also make a workspace feel more consistent when speech or small environmental sounds are distracting.
常见问题
哪种风扇预设最低沉？
“低沉风扇”和“空调”侧重较低频率；“桌面风扇”更轻，“方箱风扇”更宽厚。
不打开真实风扇也能听风扇声吗？
可以。页面打开期间，声音由浏览器生成，不控制也不需要实体风扇。
风扇声会重复吗？
它由循环噪音缓冲和稳定音调生成，设计时尽量避免明显的短录音接缝。
