Hi,
I would be very curious about your experience using the EchoPhone with paraliminals. I have one which I have used with paraliminals, and it is hard for me to judge if it does make a difference. The sound is definitely more clear since the EchoPhone amplifies the higher frequencies.
It does make a difference with music since a lot of the information in music is conveyed in the high frequency range (10-20000 cycles per second). As to whether it increases the effectiveness of paraliminals (especially since the paraliminals are mostly in the voice, 300-3000 cycles per second ) frequencies is not apparent.
