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 postioned 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.
