What does the abbreviation STS in relation to hearing stand for?
STS stands for standard threshold shift, which is the criteria for measuring occupational hearing loss. It is an average shift from the baseline measurement in either ear of 10 dB or more at 2000, 3000 and 4000 Hz. These frequencies are the most important frequencies in communication and the most sensitive to damage by industrial noise exposure.
A sensorineural hearing loss is most often associated with loss of hearing sensitivity in which of the frequency ranges?
high frequency sounds
Which ear problem is most serious?
Hearing loss
What causes neural hearing loss?
Permanent neural hearing loss most often results from damage to the acoustic nerve and the parts of the brain that control hearing. Strokes, multiple sclerosis , and acoustic neuromas are all possible causes of neural hearing loss.
What is the maximum range of sound frequencies that human can hear?
most people hear frequencies between 20 and 20,000 Hz
What is residual hearing?
This is the term used to describe the hearing that remains after a hearing loss occurs. Most people with significant hearing loss still have some residual hearing that can be stimulated by amplifying sound using a hearing aid. . www.medel.com.ar/ENG/US/50_Resources/010_glossary.asp
What dB hearing needs a hearing aid?
Various dB losses require a hearing aid. The question isn't so much what decibel loss requires a hearing aid, but at what point does your hearing interfere with your life enough that a hearing aid would prove beneficial. Because people are different, hearing aid manufacturers intentionally design an array of hearing aids suited to mild (least-affected grade of hearing loss) loss to severe. Additionally, different models of hearing aids may effect when you might wish to purchase a hearing aid. For example, original hearing aids were analog, so they were made with a specific hearing loss in mind. If your hearing changed past a reasonable range covered by your hearing aid, it might have been necessary to purchase a new one. Now, analog programmable hearing aids are adjustable, and can be programmed by an audiologist to suit your fluctuating hearing loss. Finally, and most expensively (also: what I wear) are digital programmable hearing aids. My audiologist is able to test my aided and un-aided hearing, compare it to my hearing aid programs (plugged into the computer) and change my hearing aid levels very quickly. As someone with a permanent progressive loss, this type of hearing aid is helpful because my hearing aid adjusts as my hearing does. In general, it is advisable to get a hearing aid if you have trouble hearing, if your hearing loss is affecting your relationships with others, if your safety is affected while driving, working, or at home, or if you are unable to adjust to a more physical form of communication (cued speech, American/British Sign Language, SEE, Simultaneous Communication, lip-reading, etc.). As far as hearing levels go, a minimum loss is 26-45 decibels, and your purchase of a hearing aid truly depends on the above questions as to whether or not it will be beneficial. If you believe you have a hearing loss, please consult an Ear/Nose/Throat specialist to rule out any other possibilities besides a permanent hearing loss. After that, take their advice regarding seeking out an audiology specialist to assist you in choosing which particular device would be most beneficial to you!
Why humans not listen to very low frequency vibrations?
Most humans are incapable of hearing frequencies slower than about 20 Hz.
By the age of 60 what have most people lost half of?
Unfortunately, most people by the time they hit 60, have lost half of their hearing. The ones that suffer hearing loss can now get hearing aids.
What is a channel in a hearing aid?
The frequencies which the human ear can hear are from approximately 1 Hz to about 16000 Hz (cycles per second) for most hearing aids. When this band of frequencies is split up into smaller bands, say, for example, 1000 Hz wide, the hearing aid now has 16 bands or "channels". This is done because the greater the number of channels, the more accurately one can modify the gain selectively in each channel to improve the ability of the hearing impaired person to hear frequencies where he/she has impaired hearing.

Will a hearing aid help people with mild hearing loss?
Yes. It will give them better hearing. (But, speak a touch louder) The most common type of hearing loss is nerve loss or sensorineural loss. Hearing aids are usually the best method for treating this type of loss and can significantly improve hearing abilities.
How can a bacterial infection cause hearing loss?
Sudden hearing loss--at least 30dB in less than three days--is most commonly caused by cochleitis, a mysterious viral infection.
