Active duty, retired, military contracor, or even family members - have any of you been stationed at either : Kadena, Misawa, or Yokota? If you have -What was the base like?

sound is carry in by the air, any heat insulation prevent air getting in will block the sound inside the house, material that reflect the sound created more noise, there is a NCR rating, NCR rating range from 0 to 1, closer to 0, the material is perfect reflection, closer to 1, the material is perfect absorption, you need material with perfect absorption for quietness brick is 0.01 glass is 0.05 plywood is 0.15 cork wall tiles is 0.70 most of the house they hanged a drape (NCR rating is 0.55) to absorb the noise for heat insulation check the thermal resistance R value, you need high R value for less heat loss brick R 0.44 concrete 0.80 plywood 0.94 double glass 1.69 a normal house has a combination of brick (0.44) plus 2x4stud Fiberglas (11) plus drywall (0.45) has R 0.44+11+0.45 11.89 all the new condo emphasized on height and view installed with huge double glass (R 1.69) windows are wasting lots of heat, imagine if they used fiberglass wall with R 12, they will save lots of energynot too many website has a complete material listing of R value, check the library for HVAC or ASHRAE publications
