      To explain, who we are: The IGZAB is an informal German interest group
      for the clarification of a low frequency noise, which might (!) be
      related to "The Hum" (compare Kokomo, Taos, Bristol, etc.)

      Introduction

      The HumSimulator was developed to simulate humming noise which is
      described on www.brummt.de. It should help each person, who suffer
      from hearing humming noise, to measure the frequency by comparing the
      sounds. Additionally it should be used to produce a replica of what
      the person is hearing. If these replicas are stored independently as
      wave files by different persons, they can be compared more objectively
      afterwards.

      The program generates a wavefile, which is played in a continuous
      loop. Special effort was done to calculate the wavefile in a way that
      the end perfectly fits to the beginning, which means that you do not
      realize the point where it starts again. The length of the wavefile
      should be typically 1 to 15 seconds. This length is called sound
      duration and can be set by edit / options / sound. Longer sound
      durations need more time to be calculated. In the sound options you
      also find the parameter transition. This is the time for the amplitude
      smoothly to go down and up at the beginning and end of each loop.
      Transition normally should be set to zero, except you hear a "click"
      at the beginning of each loop. (This problem only occured in earlier
      Versions of HumSimulator.)
