I'm not sure of anything definitive, but a more credible explanation is that it is some type of sonic monitoring trying to spy upon diplomats via laser micropho

  If this is true, why does the count of injured diplomats keep rising? Can’t they just shut the malfunctioning devices off? ...boosting the number of Americans affected this “sonic device” to 25 from 21, with reports of cases occurring in the last several weeks, according to two sources.

  If we're going to speculate, one could speculate that it was an anti-spying device which inadvertently caused these issues. If you want privacy you can either try to build isolated structures or rooms, or you can try to overwhelm the listener with noise. The US has employed both techniques previously. What if they were trialing a new defensive (anti-spying) technology that went wrong? The US government has certainly gone strangely quiet on this incident.

  If it was a laser microphone (or any microphone that used EM energy to monitor someone) it would require so much energy that you would not only melt whatever you pointed it at but also probably break it.

    Why, you only need to measure distance precisely to get the vibrations of a surface which is totally possible with a laser. Laser microphones do exist.

      They do exist but the point raised is that for the laser microphone to induce the effects reported the laser would have to contain enough energy such that the laser would instead be so powerful that it vaporized any glass surface it was pointed at and overheat the laser source.
