barrage jamming

The neighbors are told abc will put them up in a hotel, otherwise, they are stuck to deal with the noise, intrusion and aggravation of these fiascos. Granted, one family wins out but, the neighbors pay a big price. Don't expect your local government or the folks from ABC to give a darn if you have pets that a hotel won't take or work from home...they don't make any particular effort to keep the noise from beeping trucks, or to stop the curious from parking any where they darned please.

Honk if you love noise pollution "noise affects more people than any other pollutant the more you make NOISE the faster you lose your VOICE Your HONKERS make me go BONKERS All NOISE is waste.

So maybe a device which has a microphone built into it - such as a mobile phone - was being used with a loudspeaker connection to the car stereo? It might be possible for someone else to give you a better answer than this one if this question could be edited to say what other devices are being used near to the car stereo.
