声音计也被称为声压级计(SPL计)、噪音计、分贝计(dB计)、声级计或声音计。这是一个非常有用的应用程序,可以进行声音测试或测量环境噪音(噪音测试)
噪音计或声压级计(SPL计)使用智能手机或平板电脑的麦克风来测量环境噪音,单位为分贝(dB)。这个噪音计或声音计的分贝(dB)值可能与实际的声音计(dB计)有所不同。现在您可以轻松地使用智能手机进行噪音测量。
注意事项
分贝计或声音计(dB计)的值并不像实际的声压级计(SPL计)、声音计、分贝计或噪音计那样精确,这是因为大多数设备的麦克风都是针对人声进行校准的。为了解决这个问题,使用实际的声音计或声压级计(SPL计)在开始使用前尽可能调整分贝误差。如果您没有实际的声压级计(SPL计),可以去一个非常安静的地方,那里听不到声音,并将读数调整到20~30dB。
特点
