最适合屏蔽楼上脚步声的声音
脚步声、拖椅子声、物体掉落声。楼上传来的撞击噪音直接通过天花板结构传导——这是最难遮蔽的噪音类型之一,因为你不仅能听到还能感受到。
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
如果可能的话,让音箱朝向天花板,或者放在高架子上朝上播放。声音需要在你和天花板之间的空间与噪音相遇。
推荐声音
brown noise
Footstep impacts are primarily low-frequency (below 500 Hz). Brown noise's deep profile directly targets this range.
Recommended: 50-60 dBrain sounds
The randomness of heavy rain mimics the irregular pattern of footsteps, making them less distinguishable.
Recommended: 50-60 dBfireplace sounds
Crackling fire includes random low-frequency pops that mask impact sounds. More pleasant than pure noise for evening/sleep use.
Recommended: 45-55 dB立即试听

专业建议
地毯和软装家具能吸收反射的撞击声。将物理吸音(地毯、窗帘、软垫家具)与声音遮蔽结合使用效果最佳。
常见问题
为什么我能听到楼上的每一步,却听不到隔壁的声音?
撞击噪音通过建筑结构传导——天花板/地板就像一面鼓膜。空气传播的噪音必须穿过空气间隙,而墙壁能更有效地阻挡。撞击噪音在物理上需要质量和解耦来阻止。

What volume should I use for upstairs neighbours?
For upstairs neighbours, set your volume to 50-60 dB. This range is based on acoustic research — loud enough to mask distracting noise, quiet enough to avoid auditory fatigue during extended listening.
