An example of this quieter approach is MAG’s SILENS noise- cancelling system that reduces cabin noise to a level that allows passengers to talk to one another without headsets. The proprietary system features:
• Minimum cabin noise and vibration levels • Minimum impact on cabin dimensions • Reduced time for installation and removal • Ease of access for maintenance • No weight increase
SILENS dramatically reduces the cabin decibel level to the 77-76 dB range, and expects to have this down to the 71-69 dB range in the near future. MAG ensures they meet their own standards by measuring every aircraft for quietness before delivery.
