Do all hearing aids work the same way?
The inside mechanisms of hearing aids vary among devices, even if they are the same style. Three types of circuitry, or electronics, are used: • Analog/Adjustable: The hearing aid dispenser determines the volume and other specifications you need in your hearing aid, and then a laboratory builds the aid to meet those specifications. The hearing aid dispenser retains some flexibility to make adjustments. This type of circuitry is generally the least expensive. • Analog/Programmable: The hearing aid dispenser uses a computer to program your hearing aid. The circuitry of analog/programmable hearing aids will accommodate more than one program or setting. If the aid is equipped with a remote control device, the wearer can change the program to accommodate a given listening environment. Analog/programmable circuitry can be used in all types of hearing aids.
No. Hearing aids work in many different ways to provide the needed and desired speech signals to the listener. Some hearing aids deliver sound through the air, some deliver sound through bone conduction. Some hearing aids use FM signals, some use electro-magnetic signals (T-coils). Most hearing aids use digital technology, although some still use analog technology…some hearing aids use noise reduction technology, others don’t! In brief, there are dozens of varieties and alternatives in the way hearing aids work!
Hearing aids work differently depending on the electronics used. The two main types of electronics are analog and digital. All hearing aids, regardless of technology, are designed to increase the volume of sounds reaching the ear by electronic amplification. In order to achieve this, a hearing aid needs three basic components: • One or more microphones to gather sound waves and convert them to electrical impulses • An amplifier to increase the strength of the signal • A miniature speaker, which converts that electric signal back into acoustic energy, producing amplified sound waves that travel directly to your eardrum. The difference between analog and digital hearing aids is how the energy is amplified. Analog vs. Digital Analog hearing aids use a continuously varying electrical signal to produce sound. Digital hearing aids change the electrical impulses into binary code (zeroes and ones), and these numbers are analyzed by a microprocessor within the hearing aid.
