Oh no, another ultrasonic pet

It's that time of year again, as we approach Bonfire Night (Nov 5th) in the UK. My dog gets scared to go out at night because of the fireworks and I am now scared to go outside due to the awful, shrill, ear-piercing wailings that are common place most evening. A little background by way of explanation. As stated, I have a dog. Now, if I want my dog to come, there is a simple process, roughly as follows: 1) I shout his name, possibly followed by additional verbiage such as "Come here" or "Come on then" 2) Dog hears me and asks himself whether there might be any food involved 3) Assuming no food involved, assess whether there are any further benefits to be obtained e.g. go for walk, get a big fuss etc. 4) Assuming no benefits then ask self "Can I be bothered to go over to him really?" and, generally, as a rule, take no notice. Note that at no point in this process is it necessary for anyone to emit a noise that would be audible only to bats. My dog, like all cats I have ever known, is perfectly capable of hearing the human voice in its natural form. So why then do people (okay, I'm mainly talking about ladies here) believe it necessary to raise the pitch of their voice to near ultrasonic frequencies when calling a cat? And why do they all seem to live near me? The annoying thing is however, that not being trained singers, these women are unable to reach such high notes without getting louder as the frequency rises. An example: A few nights ago, a neighbour calls out "Tippy" to her feline. This was done in what we would refer to as a "high pitched voice." Being a cat, it naturally ignored her. So we get the next shout of "Tippy" accompanied by some "kissing" sounds, but in a higher voice. No result. So, what does she do now? Well, obviously the failure is due to her cat not hearing in the normal human audio range so she goes for it big time and attempts a full octave rise in her voice along with a doubling of the volume. This in itself is painfull on the ears but she doesn't stop there and extends the shout to "TIPPEEEEEEE" - trying to increase the pitch even further until her voice cracks into a gtteral throaty mush. Now I know that comparing cats with dogs is not perfect but I can say the word "biscuit" or "pussy cat" in a perfectly normal voice and generate an instant reaction from my dog, with no soprano impressions whatsoever. Is it really so different for cats? I feel the need to experiment. So, I think I'm going to record a selection of low and high notes onto a tape and then experiment with any moggies that happen to wander into the back garden to see if either produces a stronger reaction. Anyone witnessing this may be excused for thinking that I am wearing headphones for some audio related purpose. Wrong. They will in fact be earmuffs to protect me in case "Tippee" is needed indoors again.
