People tend to talk louder on a cell ohone than in conversation for a technical reason: They cannot hear themselves throught the earpiece. In land phones, a second signal or echo is bounced back throught the earpiece giving it a more natural sound. Not so in cell phones (something to do with signal or bandwith or something)
