The human ear is most sensitive to noise in the 1000 - 5000Hz range. AVID's DIVA is more effective in this range where most noise cancelling systems are ineffective. Noises in this range include the annyoing effects of air jets and high frequency cabin noise. DIVA provides the passenger with a full range soundstage not possible with typical headsets. DIVA does not require batteries or supplemental power, it uses existing IFE equipment.
