分贝仪高清提供了一种方法来测量环境噪音水平，显示了近似的分贝水平。
＃＃ ＃＃＃＃ ＃＃＃＃ ＃＃＃＃ ＃＃＃＃ ＃＃＃＃ ＃＃＃＃
该应用程序是基于当前的计算，以确定在分贝的声压级。
虽然我们使用专业的设备进行测试的值，我们不能保证
绝对正确性国际标准。
它还提供了一个近似的“分贝指南” ，让你知道什么声音级别对应一个健康的危害。
特点：
*在分贝的环境噪声的精确计算
*启动或停止分贝仪临的任何时间。最后的测量值被保存和显示。
*测量声级在你身边，轻松！
*清洁和专业的界面。
*平均，峰值和最大电平显示。
*数字仪表，包括平均值，峰值和最大分贝值。
*易于阅读的界面与新的Retina显示屏优化的惊人的图形！
*清爽率可调
*将设置重置为默认值。
*易于阅读的界面。
*手持分贝的参考图。
内置麦克风iPhone的是从0到约110分贝敏感。
你为什么不得到一个0分贝读数在一个安静的房间吗？
分贝是声压级的实际测量
而除了真空室或在空间0分贝是不是真的可以读取。
一个普通的安静的房间将在40-50 dB范围内。
Decibel Meter HD provides a way to measure environmental sound levels, showing the approximate dB level.
The app is based on the current calculations to determine the sound pressure level in dB.
Although we have tested the values with professional equipment, we cant ensure the
absolute correctness by international standard.
It also provides an approximate "decibel guide", so that you know what sound levels correspond to a health hazard.
FEATURES:
* Accurate calculation of the ambient noise in dB
* Start or stop Decibel Meter Pro any time. The last measurements are saved and displayed.
* Measure the sound levels around you, with ease!
* clean and professional interface.
* Average, Peak and Max level displays.
* Digital meter including average, peak and max decibel values.
* Easy to read interface with amazing graphics optimized for the new Retina display!
* Refreshing-rate is adjustable
* Reset settings to defaults.
* Easy to read interface.
* Handy decibel reference chart.
The iPhones built in microphone is sensitive from 0 to approximately 110 decibels.
Why arent you getting a 0 decibel reading in a quiet room?
A decibel is an actual measurement of sound pressure
and aside from a vacuum chamber or out in space 0 dB is not really possible to read.
An average quiet room will be in the 40-50 dB range.
