最适合屏蔽街道噪音的声音
交通、汽车喇叭、警笛、施工、大声叫喊。城市街道噪音无休无止且毫无规律——这种组合恰恰让你的大脑无法适应。
How sound helps
低频声音遮蔽: 低频噪音——交通轰鸣、邻居的低音、暖通空调的嗡嗡声、楼上的脚步声——比高频声音更容易穿透墙壁和地板。白噪音（所有频率能量均等）在遮蔽这些低音为主的干扰方面效果较差。棕色噪音将能量集中在低频段（每倍频程-6分贝），使其成为遮蔽城市环境噪音最有效的选择。

Setup guide
将音箱放在窗户附近。尽可能关上窗户。厚窗帘可以额外减少5-10分贝的物理噪音。将窗帘与声音遮蔽结合使用效果最佳。
推荐声音
brown noise
Traffic rumble sits in the 60-500 Hz range. Brown noise's low-frequency emphasis directly targets this.
Recommended: 50-65 dBrain sounds
Broad masking plus an evolutionary comfort signal: "you're inside, you're safe, the weather is keeping others away."
Recommended: 50-60 dBpink noise
For street noise that includes voices and horns (higher frequency). Pink noise's balanced profile covers a wider range than brown.

专业建议
双层玻璃窗可以将外部噪音降低25-35分贝。配合50分贝的棕噪音音箱，大多数街道噪音都会变得难以察觉。
常见问题
为什么街道噪音比室内噪音更让人烦躁？
不可预测性。你的大脑会适应持续的声音，但无法适应不可预测的声音（喇叭、警笛、叫喊声）。声音遮蔽能降低这些突发噪音的相对响度。

What volume should I use for street noise?
For street noise, set your volume to 50-65 dB. This range is based on acoustic research — loud enough to mask distracting noise, quiet enough to avoid auditory fatigue during extended listening.
