What is a Hearing Aid?

A hearing aid is a small electronic device worn in or behind the ear to improve hearing. It amplifies some sounds so that someone with hearing loss may listen, talk, and fully engage in daily activities. 
A microphone, amplifier, and speaker are the three essential components of a hearing aid. The sound waves are converted to electrical impulses and sent to an amplifier via a microphone in the hearing aid. The amplifier boosts the signal’s strength before sending it to the ear through a speaker.

How does a hearing aid help in hearing IMPAIRMENTS and speech development?

Hearing aids are most beneficial for those who suffer hearing impairments/loss caused by damage to the tiny sensory cells in the inner ear known as hair cells. Sensorineural hearing loss is the technical term for this type of hearing loss. Disease, ageing, loud exposure, and certain medications can also cause harm.
Sound waves entering the ear are amplified by a hearing aid. The remaining hair cells detect the higher vibrations and process them into neural impulses and send them to the brain. More the damage to the child’s hair cells, the greater their hearing loss will be, and greater hearing aid amplification will be necessary to compensate.

The amount of amplification a hearing aid can produce, however, has practical limitations. Furthermore, there is no conversion of huge vibrations into cerebral impulses in the case of severe ear injury. Hearing aids would not be useful in this case.

Different Types of hearing aids:

Types of Hearing AidImageDescription
In-The-Ear (ITE) Hearing aid

These hearing aids are used to treat mild to severe hearing impairments/loss and fit entirely inside the outer ear. The electronic components are housed in a durable plastic casing. However, some ITE aids may have extra functions, such as a telecoil, which improves sound quality during phone conversations. Young children seldom utilise ITE aids since the casings must be replaced frequently as the ear grows.
Behind-The-Ear (BTE) Hearing aid

BTE hearing aids are made up of a hard plastic casing that is worn behind the ear and a plastic earmold that fits within the outer ear. The electrical components are kept hidden behind the ear in a casing. Sound goes from the hearing aid to the ear through the earmold. These hearing devices are useful for mild to substantial hearing loss by people of all ages.
Canal Aid

Canal aids come in two forms and fit into the ear canal. The in-the-canal (ITC) hearing aid is customised to a person’s ear canal size and shape. Hearing aids that are completely-in-canal (CIC) are practically invisible in the ear canal. For mild to moderately severe hearing loss, both forms are employed.
They are typically not advised for young children.
