newbie Q.. i'm guessing the way to power the 5v parts of the circuit is to use a resistor to drop the ~10v you feed to those cheesy amp chips.. i ran the ~5v from my batts to those parts, and into a voltage booster to provide the 10v, it ain't working but i'm waiting on an oscilloscope to find out where. wondering if my inexperience with multivoltage circuits is the problem.

Long Range Acoustic Device (LRAD) is an acoustic hailing device, sound cannon and sonic weapon[1] developed by LRAD Corporation. Law enforcement organizations and the manufacturer claim that LRAD systems are primarily designed for long-range communications[2] however, the device has an extremely high decibel capacity, and is controversially used as a less-lethal weapon for crowd control. According to the manufacturer's specifications, the systems weigh from 15 to 320 pounds (6.8 to 145.1 kg) and can emit sound in a 30-60° beam at 2.5 kHz.[3] The manufacturer also produces systems for public address and mass notification use that broadcast 360°.[4] LRAD systems are used by law enforcement, government and defense agencies, as well as maritime and commercial security companies to broadcast audible notifications and warnings over distance. LRAD systems are also used to deter wildlife from airport runways, wind and solar farms, nuclear power facilities, gas and oil platforms, mining and agricultural operations, and industrial plants.

using a 555 for generating a stable 40khz is a BAD IDEA. It is not stable, it is not accurate. In fact the components you have used would theoretically give you ~44.5Khz, which when fed to 40khz ultrasonic transducers would result in an output at LEAST 10dB down. With precision generator and with proper tuning you would achieve at least 10x the power.

It is because of invasion right, then in the end its like i am the laughing stock in their view right due to they have the same belief? If i have this i will shoot around as revenge but who witness this to ignore, even if i am being claimed as the attacker of their life when its their misfortune? So it became logic that i am the criminal/startertotrybully if i attack back the way of reaching sound to mental attack right?

An acoustic corner reflector would efficiently reflect the sound directly back at the LRAD source as long as the reflector faces were larger than about a wavelength (for 1Khz sound, that would be about 1 foot). If you built a roughly human sized corner reflector with a hard front surface and sound adsorbing foam backing, (and wore earplugs), it should do a pretty effective job of blocking the high frequency LRAD sound while making the LRAD operator quite uncomfortable from the reflected sound.
