The design is indeed simple. I'm sure other designs would work well too, but not only is the correct pitch important, but it must have a way to convey this pitch to the lungs. One wonders if an electrical vibrator pitched to the right frequency would do the job. It would likely be more expensive to produce, but could have the advantage of being tunable in case some people have lungs with cilia that vibrate at a slightly different wavelength. Hard to believe that every single human has lungs tuned to 16 mhz exactly, but maybe at that low threshold accuracy is not as important.
