Describe the different types of hearing aids.
- Conventional analog hearing aids: These aids are designed with a certain frequency that is based on the individual’s audiogram. This type of aid will basically amplify all sounds in the same way. This is the least expensive type of hearing aid and is appropriate for many types of hearing loss.
- Analog programmable: This hearing aid has a microchip that enables the hearing aid to be programmed to meet the needs of different listening environments. For example, one setting can be programmed for a noisy environment and another for a quiet environment. Based on the individual’s hearing loss, the hearing aid is programmed for the different environments using a computer.
- Digital programmable hearing aids: This device has all of the features that an analog programmable device has, but uses digitized sound processing to convert sound waves into digital signals. This highly specialized device has a computer chip that analyzes the sounds in the environment and automatically adjusts to provide a clear, distortion-free, amplified signal.
