The ACME 636 had a big 10 dB drop when blown by a child instead of an adult, and the Fox40 micro/SOL rescue howler came in dead last with an 11 dB drop and a 1/2 mile range while most of the rest could reach out to 3/4 miles.


Actually, the SOL Rescue Howler numbers were quite similar to the ACR. For the SOL Rescue Howler, there was only a 3dB drop when blown by a kid, and the whistle was heard up to 3/4 mile. The only difference between these two whistles seems to be a slight difference in tone.

Note that he labeled the Fox 40 Micro in a confusing manner. That may be why you got the data mixed up.
