分贝计HD提供了一种方法来衡量环境声级,显示近似分贝水平。
➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠➠
应用程序是基于目前的计算,以确定在分贝的声压级。
虽然我们已经测试专业设备的价值,我们不能保证
国际标准的绝对正确性。
它还提供了一个近似的“分贝指南”,让你知道什么样的声音水平对应到一个健康的危害。
特点:
►精确计算,在环境噪音分贝
►启动或停止分贝计临任何时间。保存和显示上次测量。
►你周围的声音水平,轻松测量!
►清洁和专业接口。
►平均值,峰值和最高水平显示。
►数字仪表包括平均,高峰和最大分贝值。
►易于阅读与优化新的Retina显示屏惊人的图形界面!
►刷新速率是可调
►设置重置为默认值。
►易于阅读的界面。
►手持分贝参考图表。
iPhone的内置麦克风是敏感的,从0到大约110分贝。
你为什么不得到0分贝读数在一个安静的房间吗?
分贝是一个实际测量声压
除了一个真空室或空间0 DB是不是真的可以读取。
平均安静的房间,将在40-50分贝范围。

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.
