Re: [Phys-L] non-linear ears.

Yesterday, my G-E Dr. and I went outside, so he could remove his mask; much improved.

If three ask, I’ll place the cloth mask (and an N95, separately, of course) over my Vernier audio sensor …...…...

bc thinks is Covid "up side”, and wonders which will be better, square or sweep.

p.s. Today almost enjoyed the NCNAAPT Zoom meeting and wonder when Zoom will add sub-titles.
