Phantom vibration syndrome or phantom ringing is the sensation and false belief that one can feel one's mobile phone vibrating or hear it ringing, when in fact the telephone is not doing so.
Other terms for this concept include ringxiety (a portmanteau of ring and anxiety), hypovibrochondria (a mix of hypochondria and vibro) and fauxcellarm (a play on "false alarm").
Phantom ringing may be experienced while taking a shower, watching television, or using a noisy device. Humans are particularly sensitive to auditory tones between 1,000 and 6,000 hertz, and basic mobile phone ringers often fall within this range. This frequency range can generally be more difficult to locate spatially, thus allowing for potential confusion when heard from a distance. False vibrations are less well understood however, and could have psychological or neurological sources.
