Every pound is important. Before you decide to use only material specified for use in an aircraft check it's weight. Remember 5 pounds here and 5 pounds there starts adding up.

Has anybody added sound deadening material directly to the aluminum skins, behind the interior upholstered side panels? Maybe the trade off between reduced decibels and added weight is not enough to justify it. I was just looking in an industrial supply catalog for other items (as part of my job, NOT airplane parts) when I came across sound deadening material, and wondered if there is an equivalent aircraft grade?
