In this video I explore the possibility of making DIY sound absorption panels on a budget, later comparing them to much more expensive acoustic foam. The results are pretty amazing!

There have been many comments pointing out that my test only measures transmission and not reflection, so is essentially unsuitable for my initial testing goal. While this is partly true, testing reflection is pretty difficult to do in a home environment, and the only way to do it that I can think of would be to spend a long time in the middle of a field with a powerful speaker and mic rig, which is really beyond the scope of what I was prepared to do for the video.

My tests are not rendered pointless however – it would do no good to have only measured reflection, as the thinnest lightest material would have won (like foam), as nothing would have bounced back. Reflection and transmission need to be tested together to measure how much sound passes through, and how much sound is reflected back – this should give an indication of how much sound is absorbed by a given material.

Regardless, only testing the transmission doesn’t affect the outcome of the project at all, as any sound waves reflected by the panels themselves would have theoretically bounced off the wall anyway – again this is why reflection wasn’t tested, as it doesn’t matter so much for a panel setup (though would matter very much for a vocal booth).

Open to hear any thoughts about it though! Keep up the great discussion.

STORYLINE
The European Union banned imports of baby food containing Chinese milk on Thursday as a toxic chemical that was illegally added to China’s dairy supplies turned up in sweets and other Chinese-made goods that were quickly pulled from stores worldwide.
The 27-nation EU adds to the growing list of countries that have banned or recalled Chinese dairy products because of the contamination, which has killed four Chinese babies and sickened 54-thousand.
In addition to the ban, the European Commission called for more checks on other Chinese food imports.
Sanlu is at the centre of the tainted milk crisis.
In Hebei province, AP Television pictures show consumers returning powered milk to Sanlu staff.
Chinese baby formula contaminated with melamine has been blamed for the deaths and illnesses in China.
Health experts say ingesting a small amount of the chemical poses no danger, but melamine, used to make plastics and fertiliser, can cause kidney stones and lead to kidney failure.
Infants are particularly vulnerable.
In the southern Chinese territory of Macau, authorities found melamine in samples of a popular chocolate-filled Koala-shaped cookie made by Lotte China Foods Co. Tests found melamine in the cookies were at levels 24 times the safety limit, the Macau government reported.
The company is a member of Tokyo-based conglomerate Lotte Group.
Hong Kong supermarkets also removed the popular Japanese brand of chocolate-filled cookies from shelves on Friday.
All European Union imports of products containing more than 15 percent of milk powder will have to be tested under the new rules due to come into force Friday.
Food safety experts in the EU, which imports about 21,500 tons of Chinese confectionary products, said there is only a limited risk in Europe from the food imports.
But the European Commission says it is acting as a precaution in the face of the growing health scare.
“The European Commission is assessing the potential risk for human health, it is considering regular testing of imported products and since there is special health risk for children,” EU Trade Commissioner Peter Mandelson said at a news conference.
