Question about Swissinno Solar Ultraschall Tiervertreiber, Marder- & Katzenschreck

It's a disgrace that Galaxus sells such devices! They torture animals AND humans! But the cat still poops at the neighbours' house. Why they still run the cat scare at all is a mystery to me. It doesn't serve its purpose and instead puts an enormous burden on all of us.
Same with the leaf blowers: Noise!!! They also whirl up harmful particles and destroy (the habitat of) micro-organisms.
Such devices should be banned!

I have heard some of these things loud and clear. I don't think the sound will be that ultra. I would also like to know how many dB they work at. Because I suspect that they are above certain limits... but no one has checked that yet ;P right?

Environmental protection-environmental pollution should actually be called that.

Simply put, it is a loudspeaker that produces unpleasant noise for certain animals. So if a dog or cat is confronted with such a device in its environment, it can cause damage to health. I have also heard of people suffering from hearing damage.

To your further remarks: I hardly believe that a cat suffers from tinnitus from a bat, a whale or a tree ;-)

How is this animal distributor supposed to have an impact on the environment?

Ultrasonic waves are not uncommon in nature. Depending on the species, the localisation calls of bats have ultrasound components of up to 200 kHz in the frequency spectrum. Moths hear in the ultrasonic range up to frequencies of 200 kHz. Toothed whales, especially dolphins, use echolocation for orientation and especially for locating their hunting prey. The frequency of the clicking sounds is between 120 and 180 kHz. Mice and rats communicate by means of calls in the ultrasonic range (ultrasonic vocalisations). In rats, for example, prosocial ultrasonic vocalisations with a frequency of about 50 kHz trigger social approach behaviour.

Trees produce sounds in the ultrasonic range when there is a lack of water. The sounds occur when, during drought, the water strand in the vessels that carry the absorbed water from the roots to the tree tops and leaves breaks off. This causes cavitation bubbles to form, which briefly cause the walls of the water-bearing vessels to vibrate. The intensity of the sounds depends on the size of the vessel and the degree of dryness.

The ultrasonic frequency of the animal repellent is between 13-60 kHz. Are animals harmful to the environment?
