Question

old people cannot hear sounds even above

Answer 1

Answer:

Age-related hearing loss, called presbycusis, means that older people can't hear some high-pitched sounds they would have heard in their youth. Most people over the age of 18 cannot hear the 17,400 hertz tone in the video above.

Answer 2

Old people cannot hear sounds above 4000 Hz frequency.

Let's see a detailed explanation:

• Diminished hearing (or hearing loss) that appears in old age is also known as PRESBYCUSIS.

• In this condition, the cochlea in the inner ear is unable to hear high frequency sounds. However the low frequency sounds are well heard.

• In order to confirm the diagnosis, we usually perform PURE TONE AUDIOMETRY, in which sounds of a specific intensity and a frequency is given into the ear of the old person.

• Pure time audiometry shows a DOWN-SLOPING graph which confirms that with age, the ability to hear high frequency sound decreases.

• It is usually seen that frequencies above 4000 Hz are not well heard.
