The human ear is capable of hearing many of the sounds produced in nature, but certainly not all. Some low frequencies like a heart beat of 1 or 2 Hz can not be heard, just like sonar sounds produced by dolphins which are too high. Any frequency that is below the human range is know...
The answer lies within the fascinating world of the human hearing range. Our ears are capable of picking up a wide range of sounds: from the softest whisper to the loudest explosion. Understanding the different frequency ranges and their characteristics, as well as how our hearing works, can p...

While 20 to 20,000 Hz is considered to be the normal human hearing frequency range, this set of numbers isn’t the same for everyone—the frequency range of human hearing can change depending on age, continued exposure to loud noises or other hearing loss risk factors. As we age, the up...
Thehuman earis sensitive to sounds ranging in frequency from 20hertzto 20 kilohertz. Below about 1 kilohertz, frequency is signaled by the actual frequency of action potentials in the auditory nerve; above this frequency, however, it is the region of the basilar membrane that vibrates most that...
Although the sense of hearing is sensitive to a wide range of frequencies, there is an upper frequency limit. This limit is approximately 20 kHz for young human subjects and is gradually lowered with increasing age. The frequencies above 20 kHz are commonly referred to as ultrasonic frequencies....
of differentfrequencies, which are variouslyamplifiedby a hearing aid. The variation of amplification with frequency is called thefrequency responseof the aid. An aid need amplify sounds only within the range of 400 to 4,000hertz, although the components of speech cover a much wider range. With...
