A soft atomic break 26 essence is placed within a solenoid having several hundred turns of fine wire. The roll winding is connected to a loudspeaker. Audible results of the Barkhausen Effect are produced past times tardily moving a permanent magnet toward the solenoid core. Influenza A virus subtype H5N1 loud rasping audio volition live on heard caused past times the domains aligning themselves.
