Applying physics against a noise problem

[claudiayolga]

Hi, first of all, excuse my very poor englishI have a big problem with a bar in front of my window, in the middle of a little park. They close very late (ignoring the closing hour stablished by the law) and they make a horrible noise. Here (in Spain), there is very passivity applying the anti-noise laws, and I decided to counter-attack with the same weapons...

I want to build a device to emit a sound cone in a controlled area with intensity and frequency so that it can be enough disturbing (and harmless!) to "convince" people stop making noise so late and go home. The persons are in a 30 meters radius.

The question is very simple: I don't ask you to tell me a step-by-step guide about constructing the device (anyway...this would be nice!) but only if this is feasible, and the possible difficulties building this device.

Thanks in advance!

PD: I am mathematician, so I think I can understand some science language.

No, it's not practical. It would just be a step in an escalating noise war, with the many people (them) able to step it up each time against the one (you).

Instead, I'd look into quieting your environment, at least until you can move to a better place. Earplugs work fairly well, but even better are the noise cancelling headphones from manufacturers like Bose. You can even play music through them, and the outside noise is gone.

I know it's a hassle, but it's your most practical and immediate solution until moving becomes practical.

Wow, a bit pricey, though...
