Hearing Aids Working
All hearing aids have a few features in common. First, each hearing aid has a microphone to pick up sounds and convert the sound waves into electronic signals. Next, the signals are sent to an amplifier, which magnifies, or increases the volume of the signals. Finally, the signals are sent into the ear through a speaker. The other component that all hearing aids have in common is a battery that powers the device.
Hearing Aids use either analog or digital technology to magnify sound. Basic analog technology increases the volume of all sounds equally. In practice, this means that loud sounds may require a manual volume adjustment in the hearing aid, so basic analog hearing aids work best for people who use them in relatively quiet situations.
Let us start our tour of Hearing Aids Working by looking at the human ear itself.Sound travels through the air in waveforms, and these are gathered in by the ear and altered, before being sent to our brains to be interpreted. That is their purpose in life, so now let’s see how the ears achieve their goal.For this, the ear is divided up into three different parts; the outer ear, the middle ear, and the inner ear.

Deafness and Hearing Loss
Deafness is a condition wherein the ability to detect certain frequencies of sound is completely or partially impaired. When applied to humans, the term hearing impaired is rejected by the Deaf Culture movement, where the terms deaf and hard-of-hearing are preferred.
Hearing sensitivity is indicated by the quietest sound that an animal can detect, called the hearing threshold. In the case of humans and some animals, according to the Hearing Aids this threshold can be accurately measured by a behavioral audio gram.
Normal hearing thresholds within any given species are not the same for all frequencies. If different frequencies of sound are played at the same amplitude, some will be perceived as loud, and others quiet or even completely inaudible. Generally, if the gain or amplitude is increased, a sound is more likely to be perceived. Ordinarily, when animals use sound to communicate, hearing in that type of animal is most sensitive for the frequencies produced by calls, or in the case of humans, speech. All levels of the auditory system contribute to this sensitivity toward certain frequencies, from the outer ear's physical characteristics to the nerves and tracts that convey the nerve impulses of the auditory portion of the brain.
A hearing loss exists when an animal has diminished sensitivity to the sounds normally heard by its species. In humans, the term hearing impairment is usually reserved for people who have relative insensitivity to sound in the speech frequencies.
