Dolphin researchers have used Cyberfin, but so far have not reported on its usefulness. It drives your entire body with dolphin sounds coupled with the feeling of floating in water. It's a complete body experience, a complete immersion. You feel the vibration of the sounds, you feel the echolocation. Jennifer Hruska composed a musical score to compliment the audio-effects track.
Binaural recording is common in virtual-reality games.
Unlike stereo sound, which splits sounds from different sources onto different tracks, binaural recording records sounds exactly as they are heard. Microphones are placed inside the technician's ears so that the recording captures the natural distortions the ear makes on sounds, which indicates to the listener whether a sound is coming from ahead or behind. A person using Cyberfin not only sees and hears bubbles, but even experiences the sensation of them flitting across the skin. Whereas virtual realities have tended to be raucous environments that agitate users, people report feeling intensely relaxed and calm after their virtual swim. She says children and adults report enjoying the experience.
