hey guys(and gals)
I am getting ready to sound proof my genset box, what materials have yall used that worked great. Ihave seen some designs thru the thread search but am now looking for materials to use or where to buy.
thank you in advance

Foam covered lead sheet. All others pale in comparison. "Search" the web, as it's expensive. ...JJ |

We used a vinal coverd lead sheet type stuff to isolate computer noise in a studio. It worked great! I am planning to contact our old engineer and ask where it came from. I need some too. If I find anything out, I'll repoprt back. |

screw trying to figure out where to find it, that's easy, focus on how to pay for it.

Dick Wright at Wrico sells a foam that has a very dense polymer in the middle of it. It appears to work really well, but I cannot offer a comparison with the lead sheet.
I have seen it specutlated that using the foam / plywood and some of the cement backer board would also be effective. Masonry has long been used to effectively block sound. Its main drawback is weight, but in small amounts it might be worth it.
Another source is this company in Oregon, they have a range of soundporoofing products.

A company called Soundown in MA is a great info source and has products I have used for 30 years.
Just as in a battery , LEAD does the work , so the best noise controll will have lead at 2lb per sq ft ,2 inch foam and the facing of your choice.
Works for me,

Would it be worth the work to get a bunch of old lead pipe and melt it down and make your own sheet? I know where I could get a ton lead. |

I think the alloy of the pipe is much harder than what is used for sound control. Sheet lead is soft enough to almost stretch it with a firm push of the thumb.
Keep in mind what the sound engineer is trying to achieve.
As I understand it, in the lead/foam systems, lead doesn't deaden sound it "absorbs" the energy, but being metal, it passes the sound right thru in fairly efficient fashion, but not like the ringing of a bell*. The way the system works together is the lead, moving in response to the sound energy, changes the frequency due to its mass but also transmits the motion to the foam. The foam, by flexing, converts the motion energy to heat.
So the "vibration path" is sound source to lead (changes freq due to mass effects) to foam rubber to "heat", and results in less or "no" sound.
Onward and Upward

* Lead to silver bells are a poor comparision. Lead bells would go "thunk" but that's because its elastic properties are less than a nice silver bell and lead doesn't resonate like silver will. At the same time, lead passes the sound thru pretty well. |

I don't believe the lead in the deadening sheets is plain sheets of lead, but rather an amalgam of lead and rubber or some polymer bonded to the foam sheet.
