I'm working on a project where we are trying to prototype a whistle that works at the lowest possible air pressure and still produce an audible sound.

Any suggestions on whistle type? and any additional factors or insight that might help, would be appreciated.

Assume, Open air 72 degree Fahrenheit environment using very consistent airflow of regular 72 degree Fahrenheit air.

    $\begingroup$ Where do you get 27mph wind would apply a pressure of 2 pounds per square feet? I do not have the rep to down vote yet. $\endgroup$ – paparazzo Jan 10 '18 at 22:35

    $\begingroup$ I see you are asking a lot of questions about whistles. It seems like you're creating an XY-problem and you want the whistle to do something very specific. If you can tell us what you want to do with the whistle, maybe we can be of better assistance. $\endgroup$ – ChP Jan 11 '18 at 11:06

Native american flutes from: Intraoral Pressure in Ethnic Wind Instruments Clinton F. Goss.

This study measured intraoral pressure when playing six classes of ethnic wind instruments (N = 149): Native American flutes (n = 71) and smaller samples of ethnic duct flutes, reed instruments, reedpipes, overtone whistles, and overtone flutes.

I unfortunately mis-clicked your review (I should have rejected it), but you can still fix it by removing your unneeded comment, and fixing some other things in the post (convert the URL to a link, capital letters, and so on). If you really want to insert something invisible into a post, you can insert a html comment (<!-- comment -->). But it is unneeded in this case, because the post needs many fixes besides yours, too. $\endgroup$ – peterh - Reinstate Monica Jan 11 '18 at 5:47

  • $\begingroup$ @agentp O.k.! By improving an edit can I make it accepted on the spot. :-) Tyvm :-) $\endgroup$ – peterh - Reinstate Monica Jan 11 '18 at 12:56
