why cant I hear certain tones and pitches at 40,that I could at 20 years of age, what happened?

Answer 1

Your going deaf. Always use hearing protection when exposed to noise above 80 db. Hearing loss is painless and you wont realize it until its to late. Its also irreversible.

Answer 2

There is a certain part of your inner ear that has tiny hairs that pick up certain pitches. Over time, if you are in situation where you are exposed to very loud noises, some of these hairs can become damaged or break off completely. The result of this is that you can no longer hear sounds at those corrosponding pitches very well any more. As you can guess, these hairs are not repairable, so the hearing loss is permanent.

The best thing you can do is always wear hearing protection in any case you may be exposed to loud noises, especially in situations where the noise may not be loud enough to hurt your ears, but the noise is prolonged for long periods, such as a machining or wood shop, or flightline.

Answer 3

When you grow older, your ears mature. After the age of 20, most people can no longer hear certain frequencies that they could as children or teenagers. There are some cases where few adults could still hear those frequencies after the age of 20, but that's related to science. Ever heard of the Mosquito ringtone? Teens use it because all it is is a frequency that most people over the age of 17 aren't supposed to hear because their ears have matured. Research it.

Answer 4

Generally, everyone loses some hearing as they age, especially when subjected to prolonged noise. I am seventeen and have noticed a difference over the last few years in my left ear from my violin. Also, you may lose hearing at a specific pitch, not just at the top or bottom of your hearing range. This corresponds to the theory that different parts of your inner ear "hear" different pitches.

Answer 5

It is probably an answer that you do not want to hear. A study was even done over this as well.

When you are young, the cilia(small hairs in your ear), are very sensitive. They allow you to hear a wide range of sound. As you get older, your cilia become damaged, and erode away. This is primarily due to either prolonged high decible sound. Or frequent very loud sounds.

For instance, if you were to be exposed to an explosion, your cilia would look like they were cut in half. They CAN regrow, and you can regain most of your hearing. However, if you are exposed to loud sounds for long periods of time, i.e. music, job, etc. Then your cilia wear down in a way that will not get better.

So, bottom line is when exposed to loud sound, over extended periods of time, your hearing will degrade.

Answer 6

Human ears consists of a tymapanic membrane which is very thin. it is a stretched membrane which is covers the auditory canal of our ears and vibrates according to the the disturbances caused in the air molecules. this membrane develops totally by the age of 3 yrs and works well till the age of 30. After that the membrane due to continuous vibrations starts to gets slackening. Due to this the membrane does not catch sounds which we can hear when we are at the ages of 20's.

Answer 7

everyone's hearing gets damaged over the years. particularly loud sounds, noises and bangs are damaging to everyone's hearing. If there are particular frequencies (tones) of these loud sounds, the damage to the hearing is at those frequencies. Also, the longer the time a person is exposed to loud sounds increases the permanancy of the damage. This is less of a physics question and more of a biology question. Read about hearing damage (temporary/permanent) and protection against it at the website under Source(s) below.

Answer 8

The mechanism in the human ear which detects different frequencies deteriorates with age, Usually the high pitches go first.

Answer 9

surely it has something to do with age yet that's no longer the determining ingredient. it is genuine that as you become older you start to lose your listening to. merely like eyesight, reminiscence, notwithstanding. yet merely like eyesight, you're able to desire to be 95 and nevertheless have extra useful eyesight than a 20 3 hundred and sixty 5 days previous. it is not moving into spite of the undeniable fact that it would desire to take place. what i'm attempting to assert is which you won't be in a position to anticipate merely because of the fact somebody is older (instructor, determine, ???) it would not promptly imply they are in a position to't hear your telephone.

Answer 10

after you become a certain age(17-23) a certain sound you cannot hear anymore. some devices use these technologies to keep teens from unwanted areas.
