Room Impulse Response Measurement with MATLAB code

 

 

Impulse response measurement of my dormitory room with white noise, logarithmic chirp, and maximum length sequence (MLS)

 

First peak detection for each measurement

They all showed the same initial delay of the first peak of 186.6-7 ms.

The distance between the speaker and microphone was 60.0cm, which is the distance that sound propagates within about 1.75ms. (for the typical speed of sound in air 343m/s)

The error of 185ms might be due to the latency of the sound system of my laptop.
