追求粉噪音/棕噪音助眠（比纯白噪音更低沉、更适合遮盖交通低频噪音）需确认参数表明确标注色噪类型，多数廉价款只有单一白噪音；标准解决路径：确认色噪种类→测试外放音质有无循环→检查是否支持整晚常开→按场景选电池或USB

Unverified如果你主要需要低沉的棕噪音或粉噪音来助眠，这款提供了多档低频选项，比只有白噪音的机器更适合对高频声敏感的人82% similarUnverified白噪音（均匀）掩蔽高频杂音好，粉噪音/棕噪音低频更强、更适合掩蔽交通/低沉环境噪音；出行掩蔽车厢发动机声优先选带棕噪音/粉噪音的机型81% similarUnverified冥想音箱应优先选择支持粉噪/棕噪的机型而非仅白噪音，棕噪(brown noise)低频能量集中在500Hz以下，对屏蔽环境低频干扰(如空调、车流)和助眠效果优于白噪音81% similarUnverified解决浅眠/环境噪声干扰的标准路径：先判断噪声类型——间歇性突发噪声（关门、脚步）用白噪音机掩蔽效果好；持续低频噪声（马路、空调外机）需白噪音机+隔音耳塞或降噪耳机组合，单靠白噪音机对低频掩蔽有限81% similar
