How are your speakers hooked up? If they are part of your computer then you might get your virus scan done as there are various computer viruses that will produce wierd/interesting noises.. If the speakers are attached and activated solely through a stereo amp then you may suspect an EM (electro-magnetic) pulse which may have a number of different sources. Or...you could have experienced an unexplained bit of phenomena...possibly related to your meditations. Why is this being posted here? I'm moving it... (IMG:

PS After reading your other posts it comes to mind that when I (and others) start meditating using various chakras and energy flows you (we) could experience a number of sounds that will appear to originate from the world around us. The sounds of gulls crying, the sounds of bells or even the sounds of crickets or moving air/water. These sounds can be quite prominent when we rouse the energies of the kundalini or activate the paths of the Ina(sp?) or pingala(sp?) which crisscross around the central channel sushema (sp?). Well...before I completely bollux up this thread, I'll leave you to the 'experts'! Good Luck! (IMG:
