Question

In baseball games when the annoucer talks into the speaker, why does it sorta echo? and it sounds a little diffenrent?

Thanks. i know it proabbly isn't but would it even be possible for me to make it echo when i talk into a speaker?

Thanks.

Answer 1

It echos because you are hearing the sound from more than one PA speaker and the speakers are at different distances from each other so the sound arrives at your ears at different times.  The sound could also be reflecting of a distant object and bouncing back.  Stadium sound often has a lot of echos.

If you download the program "Audacity" it has a variable echo effect.  Yes, you can add echo to your voice.
