Describe infrasonic and ultrasonic waves and explain why humans can not hear them?
The human ear cannot detect all possible frequencies. It has evolved to detect frequencies of sounds that are the most useful to humans, and has a maximum frequency range of about 20Hz to 20kHz, which decreases as you get older, particularly at the higher end. Infrasonic describes sounds that are too low in frequency to be heard by the human ear, and ultrasonic describes sounds that are too high in frequency to be heard by the human ear. These sounds cannot be heard by the human ear because they are outside of its range of capability.
Which one of the following frequencies of a wave in the air can be heard as an audibke sound by the human ear?
The human ear can detect a wide range of frequencies. The lowest frequencies are around 16 to 20 Hertz while the highest can be as much 20,000 Hertz. As we get older, our high frequency limit tends to reduce so an older person may only hear sounds up to around 15,000 Hertz.
What wave speed can human hear?
It is not the speed that matters, but the frequency. Human ears can hear frequencies between about 20 and 20,000 Hz (vibrations per second). In older people, this range becomes less.
What is the range of frequency audible to human ears?
Approximately 20-20,000 Hz when you are young. When you get older, the range gets narrower - especially, you won't be able to hear the higher frequencies.
The upper range of human hearing is approximately Hz.?
The human hearing range is commonly given as 20 to 20,000 Hz, though there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal.

Why are tones of different frequency used during hearing tests?
Simply because the human ear can detect many thousands of different frequencies (typically 50Hz to 20,000Hz) Testing someone's hearing ability over a range of frequencies determines whether they can hear the normal spectrum of sound or not. As we get older - our hearing starts to fade - and we no longer hear the higher or low frequencies at the edge of the normal range.

How does the human life cycle change?
The human body constantly develops and changes throughout the human life cycle, and food provides the fuel for those changes. The major stages of the human life cycle include pregnancy, infancy, the toddler years, childhood, puberty, older adolescence, adulthood, middle age, and the senior years.
How does human development relate to older years?
Human development continues throughout life, including during older years. Older adults may experience physical, cognitive, and emotional changes that impact their overall well-being. It is important to support older individuals in maintaining their health, independence, and quality of life as they age.
