I'm doing an assessment at home on sound and sound insulatorsTo get a really high level I need to design some questions on this topicWe did an experiment (wrapping an electric bell in various materials and testing the best material for insulation) and the questions bit is part of the evaluation!! Please please soon!!! Thank you! xxxx
ok in basic terms to inform you Soda cans are produced from aluminum, no longer steel, in any different case they'd be very heavySo in case you may make your recycling greater helpful, it ought to be an identical fabricon the different hand, it can not be contaminated with oils, like tunain basic terms because of the fact those ones want a undeniable prewash it relatively is costlyby skill of how, washing the cans in basic terms make you waste water!!!, they're going to bathe them returned.
It depends upon your areaIn our area it's aluminum cans only; no foil, no aluminum baked goods tins, no aluminum screw caps, and no aluminum pots or pans in the aluminum recycling binOne area will accept some of these items as metal recycling; specially the pots and pansOne of the problems with foil based wrappers, wrapping paper, and decor is that the aluminum is often mixed in with other materialsIt is not readily extracted from the other materials.
The recycling scrap yards around here (in Southern Illinois) will not accept aluminum foil, or any of the other ultra-thin aluminum wrappers, lids, or packing foils But I have sold them the following types of aluminum items for recycling - aluminum cans, cast aluminum, extruded aluminum, aluminum screen wire, aluminum wire (insulated or not), aluminum breakage (parts containing a mixture of aluminum, steel, and other metals that has to be broken up mechanically to separate the aluminum out), aluminum air conditioning cores.
The real issue with recycling isn't what can or can't be recycledIt is about what is economical to recycleFoil and all those small things that you listed can be recycled, but it isn't very economical to do so, considering that they would need to be purified more than say, soda cansAlso, smaller bits of aluminum are more likely to turn into aluminum oxide, instead of melting into aluminumSo from a business standpoint, there are some things that can't be recycledHowever, if you found a backyard foundry in your location, I'm sure they would appreciate the extra metalYou would probably have this out through the grapevine, as not many people take an interest in foundries or metal casting.
Wrapping a bell in sound absorbant material, (ie: cloth, cotton, etc), will NOT give you accurate results because anything touching the bell will dampen the vibrationTo get accurate results, you need to enclose the bell in a box or other container, and line the box with the different materialsJust make sure that nothing touches the bell itself but it's supportIf you examine the internal construction of a high-qulity loudspeaker, you will see what I'm talking about.about The best sound insulation can be had by having layers: Starting with the sound absorbant material inside, a ridged inter-layer, another layer of sound absorbant and then another ridgid wall - the box it's inIf the box is completely closed, the bell should be completely enclosed and you should hear nothing, but a single rigid box with material on the inside will give you usable results for comparison.
