perception

In a recent discussion we talked about (as often happens) the unreliability of our senses as objective evaluation systems, and the voluntary but above all involuntary effect of the context and secondary information that the brain processes and of which we are almost never perfectly aware ...

If someone prefers let’s say 5 dB more bass than me, is this purely ‘taste’ or is it because they perceive less bass than me and require more for it to sound ‘right’? Same goes for all other frequencies. I’m sure this has been researched. I know participants in the Harman studies had varying...

Hello everyone! Today I am asking for your help in a research study for a class on research methods. Participation will not require anything from you except some time and a computer with web browsing and audio playback capabilities. Permission to post this here has been provided by Amir, for...

I did a small experiment with a little python code. I generated two pairs of signals, for each of them the first being a square signal, and the second signal with the same absolute frequency spectrum but with different phase. I did the first one in a non linear way, by adding a phase delay of...

Introduction In the engineering of electronic devices for music production or reproduction all designers are faced with the problem of minimizing the different forms of distortion inexorably introduced by their creations on the audio signal. They are commonly classified into two categories...

A recent discussion on the Benchmark's AHB2 discussed the consequences of an amp with measuring THD of -100 vs one with -120 dB. Although unstated, I perceived that the real issue was the audibility spurious sound energy. This got me thinking about how sound levels work across the audio...

My goal is a good-natured, civil, fun, back and forth about scientists and engineers. If this thread becomes hostile or endless back and forth sniping, I’ll beg Amir or Thomas to move it to fight club, or just delete it. Forty years ago, I started working in a Tokamak Fusion Research Lab. Since...
