描述
★最佳聲表（SPL - 聲壓級）是一種可以用分貝（dB）測量實際聲級計的應用程序。聲表還被稱為聲級計，分貝表（dB表），噪音計，聲壓級表（spl meter）。
★使用內置麥克風測量環境噪音分貝（dB），並顯示一個參考值。我們用實際的聲級計用dB校準了許多Android設備。
★最佳聲表功能：
- 表示分貝
- 顯示當前噪聲參考
- 顯示最小/平均/最大分貝值
- 按圖顯示分貝
- 可以校準每個設備的分貝
- 對聲級變化的快速反應
★美國音樂學院的噪音水平分貝（dB）：
140分貝 - 槍砲，煙火
130分貝 - 手提電腦，救護車
120 dB - 噴氣飛機起飛
110 dB - 音樂會，汽車喇叭
100 dB - 雪地車
90 dB - 電動工具
80 dB - 鬧鐘
70 dB - 交通，真空
60 dB - 正常對話
50 dB - 中度降雨
40 dB - 安靜的圖書館
30分貝 - 耳語
20分貝 - 生鏽
10 dB - 呼吸
★關於最佳聲表的重要信息：此工具不是用於測量分貝的專業設備。您必須知道內置麥克風與人聲相配（300-3400Hz，40-60dB）。因此，最大值受硬件限制，並且無法識別非常響亮的聲音（100+ db）。
記住，聲表應用只是為了樂趣，請使用它作為輔助工具。

★ 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.
