Yes, virtually every system in your body is affected by sound. Many of your organs will perform better or worse given different sonic exposure. Your emotional state is completely affected by sound. Your thought process can be manipulated or crippled by sound. The US army in Iraq uses sonic weaponry and motivation regularly in engagements. You should be wary of any very loud, very high frequency or very low frequency sound. You shouldn't expose yourself to repetitive sound for long periods of time. Any time you experience a sudden change in your health or mental state you should remember to mention changes in the sound of your environment to your physician.
