Other features

Some features that come with some hearing aids make it easier to hear in certain settings. Features include the following:

• Noise reduction. All hearing aids cut noise some. How much they cut it varies. Some also cut wind noise.
• Directional microphones. This feature involves two or more microphones. They can pick up sound from all around or from just one direction, such as in front of you. Directional microphones can improve hearing in places with a lot of background noise, such as a crowded restaurant.
• Rechargeable batteries. Some hearing aids have batteries the user can recharge. Rechargeable batteries can make hearing aids easier to use because there's no need to change the battery.

• Telecoils. This feature makes it easier to hear when talking on a telephone that works with telecoils. The telecoil picks up the sounds instead of the microphone.

  Telecoils also pick up signals in public places that have special sound systems, called induction loop systems. These systems may be in places such as churches, theaters, and airports.

• Wireless connectivity. Many hearing aids work with devices that use Bluetooth. Devices include cellphones, music players, computers, and televisions.
• Remote controls. Some hearing aids come with a remote control. This lets you adjust features without touching the hearing aid. Some hearing aids connect wirelessly to a cellphone and have an app that allows use of the cellphone as a remote control.
• Variable programming. Some hearing aids can store settings you program ahead of time for certain listening needs.
• Synchronization. If you wear two hearing aids, this feature makes them work together. So if you change the volume or the program for one hearing aid, you also change the other hearing aid. This makes the hearing aids easier to manage.
