Description
Please also check out my latest design, a Long Range Dog Whistle at 7,000 Hz. Please download here.  | I have also developed real Ultrasonic dog whistles at 20,000 Hz and above, which you can find here.  |
Dog owners no longer need separate whistles!
This whistle can be blown from either side and combines a standard double tone whistle (4 kHz) with a high pitched dog whistle at 10 kHz. Sturdy and compact. Two variants included, one with a frequency imprint and one without. Since you might not hear the high pitched dog whistle at all (depending on your age), use a freqency measuring app for testing. I use this android app.
Warning:
The whistle is very loud which can harm the ears, so please protect your ears and don't use it near other people or animals! The high pitched dog whistles may seem quiet to you, but that's because humans (especially in old age) perceive higher sounds less loudly or not at all - unlike many animals and younger people.
