As a person grows older, their hearing usually becomes worse, and they have a more difficult time hearing high frequency sounds. There is no relation to a specific age as this inability to hear high frequency sounds is affected by the kinds of sounds that a person's hearing is subjected to.
Hearing damage is greatly increased by loud noises and loud music.
Hearing damage can also cause a person to hear noise that is not actually there. This type of damage is called 'tinnitus'. It can sound like a ringing in the ears that never goes away, and is most noticeable when in a quiet room.
Hearing protection should be used to prevent hearing loss and tinnitus from loud noises and loud music.
There are several ways to reduce hearing damage.
-Reduce the level of the noise
-Reduce the amount of time that you are exposed to the noise
-Use hearing protection to reduce the loudness of the noise
-Increase your distance away from the noise
I have the same thing. I think since I am AIM running in the background, it might be someone signal thats theyve come online.... just a theory
Discipline the dog firmly but gently. Replace and move the computer cables out of reach from the dog (you can also buy repellent in a pet store which tastes very bad to the dog).
1. Velcro was made because in 1941 a Swiss engineer, George De Mestral.after returning from a hunting trip with his dog in the Alps. He took a close look at the Burrs (seeds) of that kept sticking to his clothes and his dog's fur.
There are many places on the Internet where one can find great Burberry dog supplies. One can find great Burberry dog supplies at popular on the web sources such as Amazon and eBay.
Trailing Cables are cables that are not secured in to a safe place. these cables often hazardous to to Animals and persons. eg. a pet dog bites an electrical cable and got shock to death or someone falling over cables crossing a room on the floor
yes
We can not hear dog whistles because they are far too high pitch (they are out of our hearing range). However, dogs can hear this and they respond to it as if it was a regular whistle, returning to their owner or turning their attention back to the owner. Dog whistles are also designed not to annoy other people.
Dogs have a broader frequency range than humans. The dog whistle is a very high frequency. Women can hear higher frequencies than men. Some women can hear dog whistles. Men generally cannot hear dog whistles.
Yes.
Most humans can't, however as dog whistles are just above the TYPICAL range for human hearing, a few can. All humans that can hear dog whistles have hearing ranges that are slightly above normal. Many of these people are young, mostly kids, as humans naturally loose portions of their hearing as they age. Most have lost the ability to hear this range by the completion of puberty. Some other sounds that people that hear dog whistles will typically hear are the driver circuitry on an old CRT based TV, charging circuits for strobes, failing hard drives...
"no because a dog whistles frequency is so high that no person can hear it no matter how hard you blow" You could possibly hear some sound... most dog whistles work in the range of 16-22 kHz and the human hearing range tops out around 20kHz so if your hearing is very good it may be possible to hear the whistle's lower frequencies.
Dog whistles emit high-frequency sounds that are often too high for humans to hear. These sounds can get a dog's attention and may make them bark or respond in other ways, depending on how they are trained to react to the whistle.
Dog whistles inflict pain upon the dog with their high frequency noise. The use of dog whistles in dog training is cruel and archaic.
Dog whistles emit high-frequency sounds that are not easily heard by humans but are audible to dogs. When a dog hears the sound of a dog whistle, it can be a distraction that interrupts their barking behavior. Over time, with consistent use, dogs can learn to associate the sound of the whistle with the command to stop barking, leading them to stop barking when they hear it.
Because dogs can hear higher than humans, so it attracts there attention.
It's unknown exactly how many vibrations per second a dog whistle is. But since humans can hear only from about 20-20,000 vibrations per second, a dog whistle must have more vps. Therefore, a dog whistle can range anywhere from about 40,000 vps-about 100,000 vps.
Depending on what type of dog whistle, they probably can hear at least some of the sound frequencies. Although I know of no research on this particular subject it is entirely likely that they can.
