噪声级计或声压级计(SPL 计)使用智能手机或平板电脑麦克风来测量环境噪声,以分贝 (dB) 为单位。与实际的声级计(dB Meter)相比,该噪声级计或声级计的分贝(dB)值可能会有所不同。现在您可以使用智能手机轻松执行噪声测量。 警告 分贝计或声级计(dB 计)的值不如实际的声压级计(SPL 计)、声级计、分贝计或噪声...

SPL Meter 是一款适用于 iPhone、iPad 或 iPod touch 的专业级声级计,也称为分贝计或 dB 计。 以传统模拟 SPL 计为模型,我们忠实地再现了这些仪表中的所有特性和品质,包括弹道、范围、滤波器和衰减率。 在底层,我们拥有先进的基于 DSP 的算法,符合或超过 ANSI / IEC 1 类标准。从 iOS 6 开始,我们可以禁用...
Making a SPL dB Meter In the 1980s, there was no internet as like today and so the sources of entertainment were televisions, radios and cassette players. When I was a kid, we had an audio cassette player. We used it to play songs but my imagination was always fixed to its VU meter...
噪声就不说了,音乐为啥要分贝仪,其实就是大致保持75dba左右的声音,比较利于听到和混音师一样的三频分布。 等响曲线导致,人听歌音量越高,低频和高频就更响亮。听音音量太低,人会感觉低频和高频不够,需要eq调整。 然后安卓我试了SPL Meter,支持校准,SPL A C None,SPL A。但是用了发现根本用不了,因为只在大小...
'Name','Sound Pressure Level Meter'); In an audio stream loop: Read in the audio signal frame. Play the audio signal to your output device. Call the SPL meter to return the equivalent-continuous sound pressure level in dB. Display the sound levels using the scope. Update the scope only...
The meter displays either sound pressure level (SPL), time-average equivalent sound level (Leq) or sound exposure level (LE) according to the selection made on the buttons below the display. In Leqmode the figure can be either the level since the last meter start or reset or a rolling fi...
Call the SPL meter to return the time-weighted, equivalent-continuous, peak, and maximum time-weighted sound levels in dB. Display the sound levels using the scope. As a best practice, release your objects once complete. Get while ~isDone(source) x = source(); player(x); [Lt,Leq,Lpe...
