A human baby can typically hear frequencies ranging from about 20 Hz to 20,000 Hz. However, newborns may have better sensitivity to higher frequencies compared to adults. By the age of 4-6 months, their hearing range is similar to that of adults.
Adults, usually older than 30, cannot hear some of the frequencies that younger people can. It is usually a symptom of age.
Most people can hear frequencies ranging from about 20 Hz to 20,000 Hz, with the ability to hear higher frequencies decreasing with age.
Humans can typically hear frequencies ranging from about 20 Hz to 20,000 Hz. However, the ability to hear higher frequencies tends to decline with age, and some individuals may not be able to hear frequencies at the extremes of this range.
The highest frequency that a human can typically hear is around 20,000 Hz. However, this ability tends to diminish with age, and many adults can only hear frequencies up to around 16,000-18,000 Hz.
As people age, their ability to hear high frequencies diminishes. This is due to natural changes in the inner ear that occur with age, such as the loss of hair cells that are responsible for detecting high-pitched sounds. Younger individuals can typically hear frequencies up to around 20,000 Hz, while older adults may only be able to hear frequencies up to around 12,000-14,000 Hz.
Some animals can hear higher frequencies than humans can. This is why animals can hear things like dog whistles, and we can't hear them. In all, animals can hear differently than humans in the way that they can hear more. Some animals can hear lower frequencies than humans can. Elephants can hear much lower frequencies than humans.
As humans age, the ability to hear high frequencies diminishes due to natural changes in the inner ear. This process is known as presbycusis. High frequency ring tones typically fall within the range that becomes more difficult for adults to hear as they get older, which is why they may have trouble hearing them.
Generally, frequencies above 20,000 Hz are considered too high for humans to hear. This range is known as ultrasonic frequencies and is beyond the typical hearing range of most adults. However, some animals, such as bats and dolphins, can detect sounds at much higher frequencies.
Frequencies too low for people to hear are called infrasound. These frequencies are below the audible range of human hearing, which typically ranges from 20 Hz to 20,000 Hz.
Humans can typically hear frequencies in the range of 20 Hz to 20,000 Hz, with the ability to hear higher frequencies declining as we age. This range is often used as a standard for audio equipment and music production.
There are some higher frequencies that only children can hear but adults cannot (the Viet Cong took advantage of this; children would assist patrols by telling them when they heard whistling. The patrol would shoot blindly straight up in the air and endanger the bombing aircraft that were flying over).
