以dB-SPL测量麦克风输入语音电平 [英] Measuring microphone input voice level in dB-SPL

问题描述

我发布了一个问题，以dB为单位测量扬声器的语音级别并得到答案，这是不可能的。我想开发一个测量声音的dB-SPL的应用程序。如果没有扬声器可以用麦克风这样做吗？请指导我这个问题！

I posted a question to measure speakers voice level in dB and got answer that it is not possible. I want to develop an application that measures dB-SPL of voices. If not possible with speaker is it possible with microphone to do so? Please guide me in this issue!

推荐答案

没有外部和校准设备仍然无法实现。你每天都要对麦克风进行校准，这不仅仅是从流中获取数字数据并通过某种算法运行它的简单问题。

It's still not possible without external and calibrated equipment. You're every day microphone is not calibrated and it's not just a simple matter of getting the digital data from the stream and running it through some algorithm.
