单词 Decibel Scale
释义

Decibel Scale

原声例句
传说之境

The decibel scale is what's used to measure the loudness of a sound and it's important to note that the scale is logarithmic.

分贝刻度是用来测量声音的响度的,而且重要的是要注意这个分贝刻度表呈对数曲线。

Life Noggin

And this is usually represented by the nonlinear decibel scale, where a normal conversation is around 60 decibels and a rock concert is around 120 decibels.

这通常由非线性分贝标度表示,其中正常的对话约为 60 分贝,摇滚音乐会约为 120 分贝。

经济学人 Science and technology

In air, this reduction would make a sound seem one-quarter as loud (since the decibel scale is logarithmic, every ten decibels lost roughly equates to a reduction by half in volume).

在空气中,这种减弱会使声音听起来只有原来的四分之一(因为分贝尺度是对数的,每损失十分贝大约相当于音量减少一半)。

分贝 Decibel

(重定向自Decibel Scale)

分贝(decibel)是量度两个相同单位之数量比例的单位,主要用于度量声音强度,常用dB表示。「分」(deci-)指十分之一,个位是「贝」或「贝尔」(bel,纪念发明家亚历山大·贝尔),但一般只用分贝。

常用的空气参考声压为p_{\mathrm{ref}} = 20 µPa(微帕斯卡)(rms),它通常被认为是人类的最少听觉响应值(大约是3米以外飞行的蚊子声音)。最完善的水平测量,测量1帕斯卡等于94分贝声压级。在其他介质,如水下,1微帕斯卡更为普遍。这些标准被ANSIS1.1-1994.所收录。

Decibel 分贝

(重定向自Decibel Scale)
Ejemplo que muestra 10 log10 x, x. Es más fácil de entender y comparar 2 o 3 dígitos que comparar 10 dígitos.

The decibel (dB) is a logarithmic unit used to express the ratio of two values of a physical quantity, often power or intensity. One of these values is often a standard reference value, in which case the decibel is used to express the level of the other value relative to this reference. The number of decibels is ten times the logarithm to base 10 of the ratio of two power quantities, or of the ratio of the squares of two field amplitude quantities. One decibel is one tenth of one bel, named in honor of Alexander Graham Bell; however, the bel is seldom used.
