Which high frequency sounds can dogs hear? Does that frequency hurt dogs' ears? How?
Dogs are renowned for their superior sense of smell, but they’ve got pretty sharp ears too. Compared to a human, a dog’s hearing range is approximately twice as wide. Dogs typically can detect sounds between 67-45,000 Hz, while humans can detect sounds between 64-23,000. In the upper frequencies of a dog’s hearing range, the sounds can cause a dog irritation and discomfort.Canine Hearing RangeWhile dogs are capable of hearing higher frequencies than humans, they by no means have the widest hearing range. Bats and whales can hear sounds up to 110,000 Hz, but are less capable of detecting lower range sounds.Volume Plus Frequency Equals DiscomfortIt is not merely frequency that causes a sound to be uncomfortable for a dog. The sound must reach a certain volume too. At sufficient volumes, frequencies above 25,000 Hz become irritating for dogs. The louder and higher those sounds are, the more uncomfortable for the dog they become. Dogs may whimper, whine and run away if confronted with a sufficiently loud and high-frequency sound.Practical ApplicationsHumans use high-frequency sounds to deter dogs from approaching, to distract dogs from misbehaving and to call them. Personal dog deterrents rely on blasting a loud, high-frequency sound to confuse, startle and irritate a dog. These sounds cause no permanent hearing damage and once the dog is out of range, he will settle down. In some scenarios, it’s important for an owner to signal to a dog using a sound that is distinctive. Dog whistles are extremely high frequency, in some cases, they are higher than 23,000 Hz and are inaudible to human ears. These sounds cut through ambient noise and are more easily discernible for dogs.It’s not All BadSounds of a frequency between 23,000-25,000 Hz are inaudible to humans, but are tolerable for dogs. In some cases, the sounds are appealing to dogs because they are distinct from the familiar range of sounds present in the human environment. Pet food manufacturers have experimented with including sounds in this frequency range in their adverts to attract dogs to the television set.
What are the best ways to get rid of bed bugs? How do you deal with one’s clothes in this situation? What about dry-clean only materials, or books? Will walking around an infested area with shoes on mean that the shoes are now infested?
You CAN get rid of bedbugs, although it is an uphill battle, the tiny bloodsuckers got time and patience on their side, they can survive for verrrryyyyy long periods without food(your yummy blood)!You will find it easier to get rid of them if you sleep on beds which are like thisBut, if you have beds like this then you will have difficulties.Follow the below steps if you have bed with legstake empty cans (1 for each leg, I used small empty paint cans) and fill them half with water and a few drops of turpentine oil and put them under each leg, the leg should be in the water, so that bugs which are not already in your bed don’t climb up and oil is there to discourage the ones which dare to swim across the water.Use an insect spray on every nook and corner of the bed to kill whatever bugs are already hiding in the bed, this has to be done several times so that any left out ones gets killed too.Get a roll of shrink wrap and wrap your mattress with several layers, this is to prevent the eggs and baby bugs hiding in mattress to escape. Warning: It would be uncomfortable to sleep on a shrinkwrapped mattress, but less so than getting your blood sucked.Keep an eye on shrink wrap, it may get torn due to you sleeping on it (and doing other fun activities if you are a couple), if you see it getting torn then replace it with new wraps.Make sure your blankets do not fall on the floor while you sleep at night, if your bed is set against a wall then move it away so bugs don’t climb on the bed from the wall.That’s it, you need to wait for a minimum of 6 months, I recommend at least 1 year, keep refilling the cans with water(it will evaporate), refill the oil too, and keep an eye on the bugs, if they are still biting you at night then there is a leakage somewhere, they are either still there hiding in your bed or in the blankets or coming up from some other place, wear the detective gloves and get on the job to plug the hole.If the empty paint cans look ugly under the bed, get creative, wrap up some decorative paper or something like that.This is a cheap fix but doable, I spent nothing less than 10K USD to get rid of the bug infestation, it was all waste till I used the method above.Good Luck!
