A hearing aid is a device that is designed for improving hearing of a hearing loss person by making audible sound. It helps the deaf people when they are facing trouble in hearing sound and communicate with anyone. Hearing aids are like a miniature PA system with four basic components: microphone, amplifier, a speaker, and power supply.

2. What are hearing aids?
A hearing aid is a device that is designed for
improving hearing of a hearing loss person by
making audible sound. It helps the deaf people
when they are facing trouble in hearing sound and
communicate with anyone. Hearing aids are like a
miniature PA system with four basic components:
microphone, amplifier, a speaker, and power
supply.

3. Wireless Hearing Aids
In digital world, most of modern hearing aid
have wireless capabilities.Wireless
technology allows two hearing aids to
operate together as one complete system,
instead of acting as two independent
devices. The sound input to both hearing
aids is shared and decisions about the digital
sound processing are based on the
combined information.

4. Hard-wired Hearing Aids and Wireless Hearing
Aids
People that use hard-wired hearing aids may experience a number
of issues including sound reverberation and an adverse signal-to-
noise ratio.Using the remote microphone that comes with wireless
hearing aids is advantageous because there is much less background
noise as well as reverberation.With remote microphones it is also
easier to understand words from a distance.

5. Wireless Hearing Aids and Sound Systems
Users that take advantage of Bluetooth technology can connect
their hearing aids to a computer, listen to phone conversations
with both ears, listen to televisions directly and access music
directly from their smartphones.In many cases this allows
hearing aid devices to serve as more convenient replacements
for headphones speakers.

6. Wireless Hearing Aids Compatibility
Hearing aid compatible phones have an
internal feature which electromagnetically
transfers sound signals directly to hearing
aids and cochlear implants equipped with
telecoils. Many people report feedback or
"squealing" when they place the handset of
the telephone or mobile phone next to their
hearing aid.

7. Convenience
wireless capability may also result in hearing aid features that
improve convenience. Some wireless hearing aids may be set up so
that when a we push a program button or change the volume
control on one hearing device, the change is automatically
implemented on the other side. Another feature made possible by
wireless communication is the selection of a program button in one
hearing aid and a volume control in the other hearing aid of the
matched set.

8. Connectivity
Wireless hearing aids are often capable of wirelessly
communicating with external devices as well as with each other.
There are a variety of technologies that make this possible, the
most common of which are electromagnetic fields, frequency
modulation and Bluetooth.

9. Advantage of having Wireless hearing aids
Wireless hearing devices offer a number of advantages
over non-wireless hearing aids.
● Connect Quickly and Easily
● Help for Directional Microphones
● Personalized Control
● Make Workouts Fun Again
● Crisper Sound
● Added Convenience
