The
Echofone will greatly enhance
music and sounds of many kinds from a variety of sources,
however, following the recommendations below will assure
listening enhancement.
Use a quality audio source - As
Echofone
enhances the high frequencies in
audio, a player that provides good response in the high-end is
preferable. A quality CD player, DVD player, or DAT player
will provide exceptional results. Use quality recordings.
Experiment with the ultrasound transducers - The ultrasound
transducers can demonstrate Echofone's ability to generate the sensation of sound
without any mechanical stimulation of the listener's eardrums.
To experiment with this phenomenon, try plugging your ears
while the transducers are positioned on your forehead; you will
perceive the sound without using your ears at all.
Listen for special enhancement - Much information about the
position of sounds in the recording environment is encoded in
the overtones. These overtones can often be above your normal
hearing range, however with the
Echofone you will be
able to perceive them. This perceptual expansion adds a sense
of depth to many recordings. For example, you can close your
eyes and perceive where instruments in a recorded orchestra
actually are in space.
Contrast listening with and without
Echofone - When listening using the
Echofone transducers
you may disengage the ultrasound component of the sound by
turning the "Trode" volume knob all the way to the left. This
allows you to quickly contrast the
Echofone enhanced sound with normal headphone
sound. The results are often surprising. You will perceive a
loss of tone, crispness and depth without the
Echofone ultrasound engaged.
