Low Frequency Active Sonar

A low sonar is being used to detect enemy submarines by the United States Navy.  The sound has proven effective for find other submarines.  What they do not realize is this sonar is messing up the sonar that other whales and dolphins use.  The frequency is so loud that it can permanently harm and even kill whales and dolphins.  The animals sonar waves get intermixed with the waves from the Navy detecting machines and cause disorientation. The sonar waves can also kill whales and dolphins driving them to land.  Several law suites  have been filed and they have gotten the Navy to end testing early in Hawaii.  The testing was only ended early but will pick back up next year.  We need to find a lower level of sound we emit for our sonar to track other submarines.  Endangering our sea life is no way to try and keep our lives safer.
