Post Subject: Horn against unwanted noisePosted by JAVAD on: 11/13/2010

[We are faced with a situation of unwanted noise that is coming from a rock concert at the 100 meters away from our place which is about 200*200 meters area , the power of the noise at my place is about 90 db . the noise source is being broadcast ed by speakers in 180 degree angle . I want to know that what are the proper ways of silencing this unwanted noise or at least reducing the effects on my side ,with different technology that is able to mask or reduce or silence this noise. what is the best way ,defensive or offensive to stop the noise effects and what are the proper equipments for this situation.I want to see what should be the proper size and exact horn that I can use to make a sound that can overcome the unwanted noise coming to me or can make silence.what are the mathematics of horn and what should be the frequency of the sound.
