It is Illegal to jam the phone signal in case of emergencies AFAIK. Not aware of it being illegal to jam recording devices in such an environment in which they do outline (somewhere) no recording allowed in the theatre. Audio is an odd thing in law - in the UK I can record many things audio more than you would legaly be allowed to video. But privacy laws are the ones that curtail video recordings mostly and with that - this kinda sits on the other side of the fence. However - public nuisance may prove an area and pets may well dislike this, so if anything it may be classed as an assault upon an animal. Depending upon the impact upon animals like dogs. So my main concern would be public area's with people using guide dogs - will this cause the dog distress and what would be the impact. So I'd imagine already laws that may see this fall foul of - but like many things it will be how it is used and not ownership.
