Tin foil hat radio with a metal bucket. The AM radio is completely inside a metal enclosure. This leads to a noticeable reduction in signal strength received by the AM radio. The efficiency of a metal enclosure in blocking electromagnetic radiation depends on the thickness of the foil, as dictated by the "skin depth" of the conductor for a particular wave frequency range of the radiation. For half-millimetre-thick aluminum foil, radiation above about 20 kHz (i.e., including both AM and FM bands) would be partially blocked, although aluminum foil is not sold in this thickness, so numerous layers of foil would be required
Tin Foil Phoenix August 2002. The deal guaranteed the release of their debut album in the United States, Canada, the United Kingdom, Australia, Germany, Belgium, Luxembourg and the Netherlands. In February 2002, the name of the band changed from Sonic Bloom to Tin Foil Phoenix because of legal concerns over the name expressed by their international label affiliate, Roadrunner Records. Their first full-length album, "Living In The Shadow Of The Bat", was released on September 14, 2004 by 604/Universal. They have a new single called 'Have A Nice Day' on their MySpace and their second album "Age Of Vipers" is set for release
