little ideas

reducing sound through windows:

---double-glazed helps

---triple glazong adds very little extra suppression

---another layer 4 inches away helps a lot though

---layers that are different weight densities help a lot
(glass 1/8" and acrylic 1/8" <---1/2 the weight dens)
(glass 1/8" and glass 1/4" <----twice density)

---for low frequencies (truck rumbling, etc)
seal window well
