An ex-captain of the Salem militia is infuriated by the increase of crime on the streets â HIS streets! Although the Vigilante was fired for his violent and rash methods of war, he still has a strong sense of justice, or so he tells himself. As the death toll in the Town rises, his anger only grows as he finds the killer's identity obvious.
Dogs hear at a wider range of frequencies than humans.The low end of the range is similar: 67 Hz, but dogs hear noises up to 45 kHz, while humans only hear sounds up to about 23 kHz. This means that they could be hearing and responding to sounds that we can't hear at all.
However, this results in extremely high frequencies, far higher than those that any known species can perceive (some bats can hear frequencies as high as about 250,000 Hz). Rodents can generally hear higher frequencies than humans. It's difficult to give an average frequency for the hearing ability of rats, but it would be much higher than for people. The hearing range for rats is about 200-75,000 Hz. Beyond that, I can't really answer your question, as I'm not really sure what you are requesting; hopefully this helps somewhat!
