Default Re: Radio 5 Live Echo (Empty Hall) Effect ?

Hello Mike,

I think it may depend to some extent what you define as an echo.
But apart from that I think your alternative suggestion may be true also.
Mike
I based my figure of 100mS on this Wikipedia article (See the paragraph titled 'echo, in acoustics'), and on having a vague recollection of having seen that figure mentioned elsewhere!

Whilst it may be possible to hear delays of less than 100mS on very short, non-repetitive sounds, for most normal situations in which echo occurs, I think it probably isn't.

Regards,

Dave.
