★声级计(SPL - 声压级)是一种可以测量分贝(dB)的实际声级计的应用程序。声计也被称为声级计,分贝计(分贝计),噪音计,声压级计(SPL计)。
★它使用的内置麦克风和示出的参考。我们曾校准与分贝实际声级计许多Android设备。
★你要知道,内置麦克风进行比对,以人声(赫兹300-3400,40-60分贝)。因此最大值由硬件限制的限制,并且非常大的声音(100+分贝)不能被识别。
★请记住,这只是一个设备的乐趣和请使用它作为一个的辅助工具。
根据听力学美国科学院★噪音水平分贝(dB):
140分贝 - 枪声,焰火
130分贝 - 风炮,救护车
120分贝 - 喷气式飞机起飞
110分贝 - 音乐会,汽车喇叭
100分贝 - 雪地摩托
90分贝 - 电动工具
80分贝 - 闹钟
70分贝 - 交通,真空
60分贝 - 正常交谈
50分贝 - 雨量适中
40分贝 - 安静的图书馆
30分贝 - 耳语
20分贝 - 叶生锈
10分贝 - 呼吸

★ Sound Meter (SPL - sound pressure level) is an app which can measure the actual sound level meter with decibels (dB). Sound meter is also known as sound level meter, decibel meter (dB meter), noise meter, sound pressure level meter (spl meter).
★ It uses your built-in microphone and shows a reference. We had calibrated many android devices with the actual sound level meter with dB.
★ You have to know that the built-in microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore the maximum values are limited by the hardware limitation, and very loud sound (100+ db) cannot be recognized.
★ Remember that it's only a device for fun and please use it as an auxiliary tool.
