最好的声级计

最佳音效仪表（SPL - 声压级）是一个应用程序，它可以测量分贝（dB）的实际声级计。声音米也被称为声级计，分贝计（分贝计），噪声计，声压级米（SPL米）。

它采用的内置麦克风和示出的参考。我们已经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（300-3400Hz，40-60dB）。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辅助工具。

根据美国听力学学会噪声分贝（dB）的级别：

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

百分贝 - 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 - 正常的对话

50分贝 - 雨量适中

40分贝 - 安静的图书馆

30分贝 - 耳语

20分贝 - 叶锈

10分贝 - 呼吸

Best 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.

Levels of Noise In decibels (dB) according to American Academy of audiology:

140 dB - gun shots, fireworks

130 dB - jackhammers, ambulance

120 dB - jet planes taking off

110 dB - concerts, car horns

100 dB - snowmobiles

90 dB - power tools

80 dB - Alarm clocks

70 dB - traffic, vacuums

60 dB - normal conversation

50 dB - moderate rainfall

40 dB - quiet library

30 dB - whisper

20 dB - leaves rusting

10 dB – breathing
