Analog Hearing Aids vs. Digital Hearing Aids

When selecting the best hearing aid for you, there are many options. So how do you know which option to choose? Regardless of style or placement in your ear, there are two main ways that hearing aids can work. They can either be analog or digital. Both types of hearing aids run on batteries, with the distinct difference between the two is they use different types of technology to deliver sound. We’ll walk through the benefits of each here on our blog.

Analog Hearing Aid

These are the first hearing aids, developed in the early 1900s. They used to be the only type available until digital hearing aids were released in the mid-1990s. These original hearing aids convert sound waves into electrical signals which are then amplified and transmitted back to the ear. These hearing aids can be made custom to any ear, and the noise transmission can be altered based on different environments. Some individuals prefer analog hearing aids because they generally are more affordable, and can be more powerful than digital hearing aids. There is, however, sometimes a cracking or popping noise that can occur with these hearing aids. Depending on the user’s preferences, they might prefer this sound over the digital hearing aid option.

Digital Hearing Aid

Digital aids do not use electrical signals, but instead function by converting sound waves into numerical codes and then amplifying them. One benefit of using a digital hearing aid is that the sounds waves and amplification can be controlled more specifically, and the hearing aid can be programmed to focus on sounds coming in from specific directions. However, because of this process, some also say that the digital noise transmitted in their hearing aid can be more difficult to understand than that of an analog hearing aid. It can be less clear depending on their typical environment and overall preferences. One of the significant benefits of digital hearing aids is the customization and flexibility of sound transmissions which may be the selling point for some users.


Regardless of which type of hearing aid you choose, your hearing aid should be comfortable and altered based on your hearing preferences. Most hearing aid brands offer 30-60 day trial periods so you can test the differences between options and choose the best fit for you and your life. Be sure to consult with your doctor to help make the right choice. Hearing aids can be a very beneficial investment and can improve the quality of life and increase the ability to communicate and socialize for all individuals.
