Hearing Aid Compatibility

Using a wireless phone can sometimes be challenging for people who use hearing aids. To reduce these difficulties, the wireless industry, consumer groups, and the FCC have established standards to ensure more devices are hearing-aid compatible (HAC). Today, many HAC devices are available, making it easier for users with hearing aids to find a compatible phone.

Understanding device compatibility ratings

When selecting a phone for use with hearing aids, look for its compatibility rating. Two standards are commonly used:

2011 ANSI Standard: The most widely used standard, with ratings for device compatibility and reduced interference.
2019 ANSI Standard: A newer standard that includes additional requirements, such as volume controls. However, most devices on the market are still certified under the 2011 ANSI Standard.

2011 ANSI standard ratings

Phones certified under the 2011 ANSI Standard include two ratings:

1. M-Ratings: Reduced interference

M-Ratings measure how well a phone minimizes interference with hearing aids.

M3 or M4 ratings meet FCC requirements.
- M4 indicates the highest level of reduced interference.
A higher M-rating means the device is less likely to cause buzzing or whining noises.
Hearing aid immunity to interference also plays a role. Check with your hearing device manufacturer or health professional to learn about your device’s immunity.

2. T-Ratings: Compatibility with telecoils

T-Ratings measure how well a phone works with hearing aids equipped with telecoils.

T3 or T4 ratings meet FCC requirements.
- T4 indicates the best compatibility.
Telecoils help hearing aids pick up sound directly from phones and assistive listening devices, reducing background noise.

Not all hearing aids have telecoils, so confirm with your hearing aid provider if this feature applies to you.

2019 ANSI standard

Devices certified under the 2019 ANSI Standard will be labeled as "Hearing Aid Compatible (HAC)." This standard includes:

Reduced interference and improved compatibility.
Volume controls for easier use with or without hearing aids.

As the 2019 standard is relatively new, not all phones currently meet its requirements.
