Unverified电机功率越大越安静的说法错误：静音取决于电机质量、减震和跑带材质，交流电机(AC)比直流电机(DC)更耐用安静但更贵重，家用DC电机做工好也能控制在65分贝以下84% similarUnverified直流变频电机（DC）配合无刷设计比交流电机（AC）静音约5-10dB且能耗低约60%，追求静音优先选DC无刷81% similarUnverifiedDC直流节能与低噪音正相关但成本更高：AC交流机型便宜但最低档噪音大、能耗高，不适合宠物24小时开启；预算有限且只是偶尔用可选AC，长期养宠选DC80% similarUnverifiedDC直流电机低噪静音但价格更高、最大风量往往略逊；AC交流电机风量猛且便宜但噪音大。宠物家庭优先静音选DC，纯粹为通风降温且宠物耐噪可选AC79% similarUnverified追求安静的家庭不建议买AC电机高转速机型：AC电机满负荷揉面噪音常达75-85dB，DC电机及带减震设计的机型噪音明显更低75% similar
