Presumably because he didn't want it in the house noising things up, but that hints at the annoyance he has imposed on the rest of the neighborhood. It's not too bad unless you want to open your windows and let the breeze cool you off when inside instead of the ol' AC.
Anyway, the parrot itself isn't really all that annoying, but I'm having trouble resisting the urge to train it to say, "I hope my wife doesn't find out about this."
Is that so wrong?

Thereby eliminating incriminating tracks, etc.

Figure the length as stated and use 16 tubes instead of 32. The cutoff frequency will not be as sharp for each tube as to be disturbing and will enable the user to either hear or to narrowcast sounds readily enough.
The finished diameter would be somewhat larger than Rich's but with fewer tubes, it wouldn't become cumbersome. Using a funnel arrangement to guide the sound in or out would be simple to arrange also.
You could use it as a science fair project and impress your friends and parrots.

Capn Lazarus wrote:You probably would, Rich but we know you're using that as a bad example.
Your logic dictates material for the most efficient device possible--expedience would support less efficiency just to get the job done. You could even use PVC as 'proof of concept' and refine it later, if necessary.
I'll admit that I never thought of a shotgun speaker before this. The same design for an efficient directional mike is all I've considered. The same transducer could be used for both with a small sacrifice in efficiency.

Most mikes lack the area to radiate sound efficiently.
