完美探針表

★最佳声表（SPL - 声压级）是一种可以用分贝（dB）测量实际声级计的应用程序。声表还被称为声级计，分贝表（dB表），噪音计，声压级表（spl meter）。

★使用内置麦克风测量环境噪音分贝（dB），并显示一个参考值。我们用实际的声级计用dB校准了许多Android设备。

★最佳声表功能：
- 表示分贝
- 显示当前噪声参考
- 显示最小/平均/最大分贝值
- 按图显示分贝
- 可以校准每个设备的分贝
- 对声级变化的快速反应

★美国音乐学院的噪音水平分贝（dB）：
140分贝 - 枪炮，烟火
130分贝 - 手提电脑，救护车
120 dB - 喷气飞机起飞
110 dB - 音乐会，汽车喇叭
100 dB - 雪地车
90 dB - 电动工具
80 dB - 闹钟
70 dB - 交通，真空
60 dB - 正常对话
50 dB - 中度降雨
40 dB - 安静的图书馆
30分贝 - 耳语
20分贝 - 生锈
10 dB - 呼吸

★关于最佳声表的重要信息：此工具不是用于测量分贝的专业设备。您必须知道内置麦克风与人声相配（300-3400Hz，40-60dB）。因此，最大值受硬件限制，并且无法识别非常响亮的声音（100+ db）。
记住，声表应用只是为了乐趣，请使用它作为辅助工具。

★ 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 to measure environmental noise decibels (dB) and show a value for reference. We had calibrated many android devices with the actual sound level meter with dB.

★ Features of Best Sound Meter:
- indicates decibel by gauge
- display the current noise reference
- display min/avg/max decibel values
- display decibel by graph
- can calibrate the decibel for each devices
- quick reaction on sound level change

★ 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

★ IMPORTANT information about Best Sound Meter: This tool is not a professional device to measure decibels. 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 sound meter app is only for fun and please use it as an auxiliary tool.
