"<p>声强, 也称为声学强度，是指单位面积内声波在垂直于该面积的方向上所携带的功率。声强的国际单位制，是瓦特每平方米。</p>" }, { "question": "什么是声强级别?", "answer": "<p><strong>声强级&nbsp;(SIL)</strong> 是声强值相对于参考声音强度值的相对值(对数)。</p>" }, { "question": "声强和声压相同吗?", "answer": "<p>声强 与声压的物理量不同。人的听觉对与声强有关的声压直接敏感。在消费类音频电子产品中，电平差异称为&ldquo;强度&rdquo;差异，但声强是一个专门定义的量，不能由麦克风简单的感知。</p>" }, { "question": "测量声强需要什么设备?", "answer": "<div>\n <div class=\"group w-full
