Does your plasma tv make a buzzing sound?

From the experts:
Yes, some plasma TVs make a lot of noise at high altitudes. That noise is the mechanical ‘buzz’ created during the plasma’s on-off imaging cycles. At low altitudes, the air pressure is sufficient to keep the glass from vibrating very much. But at high altitudes, air pressure is lower, so the glass vibrates more – and you hear it.
