General Hearing Aid Overview
Hearing aids are portable devices you wear in or behind your ear to hear more clearly. They amplify and process sounds so that a person with hearing loss can communicate and participate in daily activities more easily. In quiet or noisy environments, hearing aids can help people to hear more of what they want to hear, and less of what they don’t.
Simply stated, hearing aids consist of a microphone, flexible printed circuit board, battery and receiver.
- First, the microphone picks up the sound from the environment and converts it into an electrical signal. Hearing aids can have more than one microphone, which is referred to as a directional microphone system. This system is designed to prioritize sound in front of the listener, key for maintaining comfort in noisy environments. Digital technology converts the incoming signal from the microphones into digital code. That code is then analyzed and adjusted based on the listener’s environment and degree of hearing loss.
- The flexible printed circuit board consists of more than 60 different components and integrated circuits. It is often thought of as the brains of the hearing aid. The flexible printed circuit board contains both the digital signal processing chip and the radio used to communicate with an iPhone or Android telephone.
Fun fact: The processing power of the printed circuit board inside the newer hearing aid is magnitudes greater than the computers aboard the Apollo 11 space shuttle that landed on the moon!
- The battery provides the power for the hearing aid.
- The receiver converts the amplified electrical signal into sound and delivers it into the ear without distorting or limiting the sound.
There are several types of hearing aids, each with their own specific benefits. Let’s explore each type:
