WideNoise是一款iPhone应用，它对噪音分贝值进行抽样测量，并将音量值显示在交互式地图中。
WideNoise is an iPhone application that samples decibel noise levels, displaying them on an interactive map.
五格信号强度的分贝范围很大，因为在信号好的地方精确测量信号并没有在信号差地方测量那么重要。
The decibel range for five bars of reception is so large because precise measurement in such an area is less important than in areas with poor reception.
在您手机漂亮的图形用户界面下，你的手机通过分贝来测量那五个信号格。
Underneath the pretty graphical UI, your cellphone measures those five bars in terms of decibels.
很明显，你可能很想知道，为什么iPhone不用更线性的方式来测量接收强度，每格表示的分贝值相同呢？
Obviously, you'd wonder why the iPhone wouldn't measure signal in a more linear fashion, where the decibel value for each bar is equal.
电视机和收音机加起来90或J 00分贝，某单位用来测量声音的响度。
TV sets and radios add up to 90 or J00 decibels, a certain unit used to measure the loudness of sound.
噪音测量装置：用于八小时工作小时之外测量噪音分贝量的仪器。
Noise DOSIMETER: Instrument used to measure in decibels the amount of noise an employee is exposed to over an eight hour work day.
它能精确测量任意波形的低频模拟周期信号并同时显示其有效值和分贝值。
It not only can measure the discretionary low frequency analog signals exactly, but also can simultaneously show their virtual values and decibels.
水下测量的分贝值不同于在陆地上测量。
Decibels measured in water are different from those measured on land.
它能精确测量任意波形的低频模拟周期信号并同时显示其有效值和分贝值。具有智能量程转换功能。
It not only can measure discretionary low-frequency analog signals exactly, but also can show their virtual values and decibels synchronously, which has the intelligent selectiveness of measure.
