Telephone Communication

[defscarlett]

I have searched every corner of the internet, or so it seems, looking for this information and I just can't seem to find reliable information. I'm looking for hard numbers on how communication over the phone is different than face to face communication in relation to the below quote.

7% of the message is transferred and understood by the actual words used, 38% is transferred as a result of the way the words are spoken and a massive 55% by body language

I'm finding numbers listed in some articles and power points on slide share, but they are not sourced and the numbers are so dramatically different that I'm not sure what is reliable and what's not.

Anyone have any ideas where I can find this information, or good search terms to use?

Did you see this

The 'Mehrabian formula' (7%/38%/55%)
