Frey discovered that the microwave auditory effect, i.e., the reception of the induced sounds by radio-frequency electromagnetic signals heard as clicks and buzzes, can be blocked by a patch of wire mesh (rather than foil) placed above the temporal lobe.&lt;p&gt;I&amp;#x27;m ready &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;static.tvtropes.org&amp;#x2F;pmwiki&amp;#x2F;pub&amp;#x2F;images&amp;#x2F;weirdalfoil_2322.jpg&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;static.tvtropes.org&amp;#x2F;pmwiki&amp;#x2F;pub&amp;#x2F;images&amp;#x2F;weirdalfoil_232...&lt;/a&gt;</text><parent_chain><item><author>QAPereo</author><text>&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;en.wikipedia.org&amp;#x2F;wiki&amp;#x2F;Microwave_auditory_effect&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;en.wikipedia.org&amp;#x2F;wiki&amp;#x2F;Microwave_auditory_effect&lt;/a&gt;&lt;p&gt;This is the best bet I&amp;#x27;ve seen since this story broke.</text></item><item><author>mccoyspace</author><text>This is such a fascinating (and disturbing) situation.
