Sound projector *parabolic*type*

[Sanon]

Hi Board,

Where can I get information regarding sound projection with parabolic reflectors . I need to know what equation governs the gain and at what frequency range.


Thanks in Advance

You can send the sound in microwaves. Does that make any sense to you (directionality), or what you want is different.

To me it makes sense . Micro intended as a fraction of the original sound ,I presume . And the parabolic shape acts as a conveyor .

No , I just want the sound from my speaker more directional to the listner. Microwave link is a different issue.

Hey Sanon,
something like this?

exactly , but design paramters and theory is what I need .

Hey sanon,
Most of the design details are laid out in the info on the site.
and this site has info on parabolic reflectors Instructions for Making Big Parabolic Reflectors
