Can you hear "ultrasonic" pest repellents?
I’m not asking if the human race as a whole can hear them, I just want to know how many of YOU can hear them. I’m dogsitting right now, and this person has a couple Viatek ultrasonic pest repellers. I can most definitely hear them, and they’re quite annoying. BEEEEEEEP……..BEEEEEEEP……BEEEEEEEP…..but VERY high-pitched, and with a very steady beat. I KNOW they are the pest repellers, because it’s louder when i put my ear up to them. I had no idea what the sound was when I first walked in. In reminds me in a way of the sound a muted TV makes when you turn it on.
I have heard the ultrasonic dog trainer thing at work, the PetAgree, but I always figured the batteries were going dead, and thus the pitch was lower. These things are NOT going dead, as they are plugged into the wall.
So…can anyone else hear those types of things, or am I just some sort of freak of nature? o.O
Just though I might add…I was curious, and I recorded it on Audacity with my computer, and it says it’s approximately 33 kHz. Good lord, I had no idea. And I also realized – I can’t -always- hear it. I was blasting Les Mis soundtrack as high as I could all day today, and I can’t hear it at all at the moment. Its particularly loud and obnoxious in the morning.
And the ultrasonic dog trainer at work – that’s even high pitched, I wonder just how high it is?
