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.
Humans cannot hear sounds of every frequency. The range of hearing for a healthy young person is 20 to 20,000 hertz. The hearing range of humans gets worse with age. People lose the ability to hear sounds of high frequency as they get older.he range of hearing for a healthy young person is 20 to 20,000 hertz. The hearing range of humans gets worse with age.
