How to Use
Echofone |
| |
|
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.
