Disposable vs. Rechargeable Hearing Aid Batteries

All hearing aids require a power source, but many modern hearing aids have the option of either a disposable or rechargeable battery. Which option is the best for you?

Benefits of Rechargeable Batteries:
1. Convenient – Instead of having to frequently repurchase batteries over the lifespan of the hearing aid, you simply charge the hearing aid at night while you sleep. The hearing aid then has battery power for up to 30 hours on a single charge. The internal battery can be charged thousands of times before needing replacement. 
2. Easy to Use – Disposable hearing aid batteries are very small and can be difficult to change for some people. Rechargeable hearing aids easily pop into a charger, so there is no fumbling with small pieces.
3. Environmentally Friendly – Given that most disposable hearing aid batteries last about 5-7 days, you will ultimately throw away hundreds of batteries over the lifespan of hearing aids if you use that option. Although hearing aid batteries can be recycled, disposable batteries create much more waste over the lifespan of a hearing aid compared to 2 rechargeable batteries. 

Benefits of Disposable Batteries:
1. More portable – Disposable batteries are much easier to take on the go, since you don’t have to pack the charger with a power cord. A pack of disposable batteries is small enough to easily fit in a pocket or wallet.  
2. Little downtime – When disposable batteries die, it’s as simple as changing to a new battery in a matter of seconds to power your hearing aids again. When the charge dies on rechargeable hearing aids, it typically takes a couple of hours for the hearing aids to fully recharge, which is especially inconvenient if you don’t have your charger with you. 
3. Different hearing aid style options – Certain styles of hearing aids, such as tiny invisible in the ear hearing aids, are only able to be powered by disposable batteries. Other types of hearing aids, such as behind the ear styles, typically have the option of either rechargeable or disposable batteries. 

The best hearing aid battery option for you is a matter of lifestyle and personal preference. An audiologist can help you decide what the best choice is to fit your needs. 

Types of Hearing Protection

One of the prominent causes of hearing loss is excessive noise exposure. For many patients, they have grown up hunting and target shooting, or have worked many years in a very noisy job. Unfortunately, one the damage from noise has been done, there is no way to reverse it. Instead, we ask all of our patients to use hearing protection when they are going to be around excessive noise.

There are different types of hearing protection. The one that works the best is the one that you will wear consistently and properly.

Styles:

  • Over the ear: These devices look like headphones, or are sometimes referred to as “Mickey Mouse ears” due to their bulk.  These cover the external part of the ear and block out many external sounds.
  • In the ear (non-custom): These devices are generally available at drug stores and are made of foam or plastic.  Non-custom devices fit into the ear with a tight fit and come in an array of sizes.
  • In the ear (custom): For a more secure fit, custom molded hearing protection can be made. This requires a silicone-like mold of your ear to be made, then sent to an outside company for crafting. These are typically a rubber-like material.

Types of Sound reduction: Hearing protection can be divided into two categories of sound reduction; active and passive.

  • Passive: Passive hearing protection uses the physical piece as the method of blocking the sound. These are less expensive than active hearing protection as there is no electronics within the devices. The foam hearing protection that is seen at drugs stores is a form of “passive” hearing protection. Passive hearing protection can be custom and non-custom.
  • Active: Active hearing protection uses not only the physical properties of the device, but also electronics to reduce sound.  Active hearing protection uses external microphones to analyze sounds in the surrounding area, then shut off when a loud sound is identified. Many hunters utilize active hearing protection to hear their environment, but the sound of the firearm is reduced. Active hearing protection can be custom or non-custom.

Here are some situations where Hearing protection should be utilized:

  • Hunting/shooting
  • Power tools, including lawn mowers
  • Noisy work environments – factories, mills, military, aircraft

If you are interested in custom hearing protection, JHBI can help. We are able to take custom molds and order both active and passive hearing protection.
