This is translated from Dutch.

I am postman. Where I post delivery is a cat repellent. This device emits a beep painful. The noise caused me tinnitus and ear pain. The volume of the Solar Garden Guard is 140 decibels. 1500m2 area. The total range is 39 meters. More people have this nuisance? The sound resembles the Mosquito against loitering.

I'm sorry, I have no experience with cat repellents. I am a cat owner and would not use them. However, I do use insect and rodent repellents that plug into the outlets. They are supposed to be hypersonic, heard by the insects and rodents but are not supposed to be heard by humans. They are easily heard by humans at a very high pitch from a distance of a few feet. I try to keep them in places that are blocked by furniture or other types of barriers. These do not 'repel' my cat and I'm not even sure if she hears it. I've heard that these repellers used in the yard for cats, dogs, moles etc. do not even work but I don't know. They are very irritating sounding and I agree that the beep can be painful. Since you are exposed for a very short duration, it sounds like there may already be an underlying problem with tinnitus or hyperacusis and the repellent is either more noticeable as a result or is making it worse. Talk with your employer, they may be able to do something to get the homeowner to stop or maybe the city can do something. Have you been tested by an audiologist? Good luck.

In Kent, a school child has to cover her ears every time she walks past a house that has a cat deterrent. She says she does not like the sound. Her mother cannot hear anything so does not know how loud the sound is or where it comes from. The cat deterrent is in a plant pot near the ground, so it is close to the young child's ears.

In London, a 4 year old child was playing in front of a cat deterrent. Her parents had no idea that the 4 year old could hear it. The 12 year old came home and asked the parents why the cat deterrent made a noise, and this was when they realised that their 4 year old was playing in front of a loud noise that she could hear. They got rid of the cat deterrent.

In London, children living next to bird deterrents had ear pain, tinnitus, nausea even vomited when the neighbours who installed the bird deterrents refused to turn them off.

etc etc

The elderly in particular use a cat-deterrent in their garden. It is a small apparatus with a speaker attached to it. It produces a high-pitched bleep of more than a 100 decibel. The sound is mostly only audible for children, youngsters and people with ears that are still good. Many cat-deterrents use the same noise as the Mosquito. The sound causes pain in the ears, headache, and ringing in the ears. If you have any complaints consult your GP and make mention of it on social media!

120 decibel.

140db's! would scare anything and possibly result in problems. Have you ever been anywhere near one of those tree mulchers/shredders even for a second or two. Regarding the cat watcher well it probably highlights the stupidity of humans who invented this thing and those who approved of its use. Don't like cats! well there are many things you can do to keep them out of your yard without scaring the daylights out of everybody and everything.

Pieptonen I would say that depending on the amount of time somebody was exposed to the noise would probably determine the degree of damage to their hearing system. It is important however that you understand anxiety and worry will always impact on ones perception of tinnitus
