HI,

I'm doing some research on "perception of tempo" when listening music by headphones or over the speakers. I have some sound engineer friends claimed that they "perceived tempo changes" when listening by headphone and over the speakers.

When I meant by "tempo changes" here, is the "perception" the tempo
of the music is different when you listen via headphones and speakers.
(same piece of music)

It might sound " this is impossbile", but personally, me and a few
sound engineers do perceive some "Tempo changes" when listening by
headphones and speakers.

It's not a Drastic Tempo Changes, just the "perception" of the tempo is
different, either listening by headphones are faster; listening over
speakers are slower or vice verses."perception of tempo change"= e.g. Original music - 120 bmp;

Listening over speakers - perceived 120bmp; Listening by headphones-
perceived 125bmp

But certainly we are not sure how many ppl out there perceive the
same oracles or similar experience.

just wondering any of you hv similar experience??

p.s- I need to emphasize that is the "perception" of tempo is changing,
and not the actual tempo of music is changing
