Echofone extends your hearing perception to frequencies which are ordinarily well above your hearing range. Incoming high-frequency sound is converted to ultrasound and transmitted to transducers which contact your face. The ultrasound travels though your skin into the inner ear, where it is perceived as high frequency audible sound. Integrated with high quality stereo headphones, the Echofone headset provides a full spectrum audio experience.
Echofone was originally designed as a research tool to provide accurate perception of dolphin sounds. In fact, if you've ever had the opportunity to swim with dolphins and hear their echolocation sounds, you will be amazed by the accuracy of Echofone's sound reproduction. By allowing you to perceive spatial information embedded within high frequencies, music and sounds gain dimension. You can actually sense where the instruments are located in a recorded orchestration when perceived through the Echofone. If you have any high frequency hearing loss, such as damaged caused by exposure to loud sounds, Echofone allows perception of the full dynamic range of music without missing the high frequencies.
The Echofone package includes high fidelity stereo headphones with ultrasound transducers, an audio CD of dolphin sounds and music composed using dolphin sounds as instruments, a user's guide, a set of independent transducers for experimentation, and a cable to connect the Echofone to any headphone or line-out audio source.
