The wireless industry is committed to providing a selection of compatible phones for those customers with a hearing impairment. These ratings have been developed to assist hearing aid device users in finding phones that may be compatible with their particular hearing aid device. From this page you can access a series of questions and answers related to hearing aids and wireless phone interactions; obtain a list of wireless phones that may offer T-coil coupling and/or may have potentially lower levels of interference; obtain a list of useful accessory options.

The Federal Communications Commission (FCC) has passed a set of rules designed to make mobile phones more accessible to persons with disabilities. The FCC created a rating system to help consumers with hearing disabilities find a phone that will work with their hearing aids. Wireless phones rated "M3" or "M4" meet the FCC requirements for hearing aid compatibility and are likely to generate less interference with hearing aid devices. "M" refers to using the phone with a hearing aid in the microphone setting. The higher the "M" rating, the more likely it is you will be able to use the phone with your hearing aid on the microphone setting. Thus, M4 is the "better" or higher of the two ratings. "M" refers to using the phone with a hearing aid in the microphone setting. The higher the "M" rating, the more likely it is you will be able to use the phone with your hearing aid on the microphone setting.

What is a "T" Rating? "T" refers to using the hearing aid set on telecoil. The higher the "T" number the more likely you will receive better interoperability performance between your phone and hearing aid on the telecoil setting. Thus the T4 is the ‘better’ or higher of the two ratings. Reduced feedback and reduced background noise are additional benefits of using a hearing aid set on telecoil during phone use. To determine the likelihood of successful cell phone use with your hearing aid, add the "T" rating number of the cell phone to the "T" rating number of your hearing aid.

Hearing Aid Users - Selecting the best phone for you

Because hearing loss is so individual, no hearing aid and wireless phone combination can be guaranteed to work for everyone, however this information can be used to point hearing aid users in the right direction. Consumers should always try a phone to see if it works for them.

Frequently Asked Questions

Q. What does hearing aid compatibility (HAC) mean for wireless devices (e.g., Cell Phones and PDAs)? A. The Federal Communications Commission (FCC) defines HAC for wireless devices in terms of two parameters; radio-frequency (RF) emissions and telecoil coupling. Cell phones are tested to see if they comply with the FCC’s definition of hearing aid compatibility.

Q. How will I know if a wireless device is rated for HAC? A. Information about whether a wireless device is rated for HAC can be found in three places:
1) on the display cards next to devices in service provider operated retail stores,
2) on the packages containing wireless devices, and
3) in the product’s manual or packaging insert. The packages and display cards will be labeled with an "M" and/or "T" and a rating number. Only devices that are rated for HAC will be labeled in this way. If you see an "M3", "M4 T4" or "T3" label on the display card or packaging then the device is HAC compliant. If you have questions about the rating of a wireless device, ask the service provider or device manufacturer for more information.

Q. What does an "M3" or "M4" on the label mean? A. "M" refers to the device’s RF emissions level, and means the device is intended for use with hearing aids in microphone mode. The higher the "M" rating number on the device, the more likely you will be able to use the device with your hearing aid on the microphone setting.

Q. What does a "T3" or "T4" on the label mean? A. "T" refers to the device’s telecoil coupling ability, and means the device is intended for use with hearing aids in telecoil mode. The higher the "T" rating number on the device, the more likely you will be able to use the device with your hearing aid on the telecoil setting.

Q. Are there wireless devices I can use with my hearing aid on the telecoil setting? A. Quite possibly. The FCC requires that wireless devices be rated for HAC specifically for hearing aids in telecoil mode. These devices are labeled with ratings of T3 or T4.

Q. Do the HAC ratings guarantee that I will be able to use a cell phone with my hearing aid? A. Wireless devices that are rated for Hearing Aid Compatibility (HAC) should improve usability for hearing aid users. However, because of the highly individualized nature of hearing loss and hearing aids there is no guarantee.

Q. May I try a wireless device before I buy it? A. Yes, it is advisable to try a wireless device with your hearing aid in the store before making a purchase. It’s best to try several devices before buying to find the best match with your hearing aids. Visit a full service carrier store and ask to try devices that have been designated as "hearing aid compatible."

Q. Can I return a phone if it does not work for me after purchase? A. It depends on the return policy. Be sure to understand the return policy, as well as, any early termination fees before signing up for any cell phone or service. Since a cell phone’s RF emissions can change depending on your location, be sure to fully evaluate your listening experience outside the store during the return period.

Q. Who manufactures wireless devices that have been approved as HAC by the FCC? A. All major handset manufacturers are required to offer HAC-compliant devices and may also offer hands-free accessories to improve usability.

Q. Do HAC compliant wireless devices look any different from other devices? A. No. Q. Does the information in this brochure apply to cochlear implants also? A. Cochlear implants are not regulated by the FCC and therefore are not rated. However, devices rated for HAC may make it more likely that a cochlear implant user will be able to use a cell phone with minimal interference either on the M or T setting. The same rule of thumb applies though – try before you buy. Try before you buy. It’s best to try several phones before making your purchase to find the best match with your hearing aid.

Q. Are devices rated for HAC more expensive than devices without hearing aid compatibility? A. No, the range of features and functions of wireless devices will impact the price, but hearing aid compatibility will not. Service provider owned and operated stores will offer a range of devices with varying features and prices.

Q. I already have a wireless device. May I trade it in for a hearing aid compatible device? A. You will need to consult with your service provider.
Q. What if I cannot find a wireless device that works with my hearing aid? A. You can check with your hearing healthcare professional to determine if there is a hearing aid option for you that may work better with wireless devices. Some telecoil users may find that accessories such as neckloops may further assist with their use of wireless devices.

Q. How can I be "hands free" while using my wireless device? A. Many states now require "hands free" driving while using wireless devices. If you use a telecoil, you may be able to use a neckloop. If you use the microphone mode in your hearing aid, you may be able to use the speaker phone function available on some wireless devices. If there is a Bluetooth accessory for your hearing aid, it may be able to work with Bluetooth enabled wireless devices. Remember safety first while driving.

Q. What is a telecoil? A. A telecoil is a small device that is built into some hearing aids for use with the telephone as well as assistive listening devices. To use the telecoil, generally either the hearing aid is switched to the "T" position or a button on the hearing aid is pushed to select the telecoil program. Some newer hearing aids will automatically switch to telecoil mode when using a phone. The telecoil picks up magnetic fields generated by telephones and converts these fields into sound. Telecoils are particularly useful for telephone communication because they permit the volume control of a hearing aid to be turned up without creating feedback or "whistling," and background noise can be reduced especially when using cell phones in noisy places. To determine whether your hearing aid contains a telecoil and how it is activated, ask your hearing health professional.

Q. What does hearing aid compatibility (HAC) mean for hearing aids? A. Using the same measurement standard that wireless devices use to test for HAC, hearing aids can also be tested and rated for compatibility. This standard measures and rates the hearing aid’s immunity to the typical electromagnetic outputs from wireless devices. An M1 or T1 is the poorest immunity rating, and an M4 or T4 is the best immunity rating. Your hearing healthcare professional may assist you in determining if your hearing aid has been rated.

Q. How do I know if my hearing aids will work with a particular cell phone? A. If your hearing aid is rated for HAC like many wireless devices are, then there is a method for prediction: just add the rating of your hearing aid to the rating of the wireless device. A hearing aid rated M2 and a wireless device rated M3 combine to a give an M rating of 5 and would likely provide "normal" use. An M rating combination of 6 would likely provide "excellent performance". The same would be true of T ratings. The higher the combination, the better the user experience is likely to be. Every individual’s hearing loss is unique so ratings do not guarantee performance. Source: http://www.accesswireless.org/hearingaid/

“My old hearing aids would move around when I chew food and they made my ears itchy and sweaty. They were not comfortable and, for that reason, I wouldn’t wear them all the time.”

“I hear better with the Delta’s and I’m more comfortable. I’m not even aware that I’m wearing them. It’s the greatest thing. You put them on and forget about them. There’s no comparison between these aids and my old aids.”

Annette M. in Sun City Center

“Absolutely wonderful. The entire staff is exceptionally friendly and they just bend over backwards to help you. I’ve never witnessed anything like it in any other hearing center I’ve visited. The place is just phenominal. It’s been three weeks since I got them (OTICON DELTA’S) and I’m still euphoric. I’m hearing sounds I haven’t heard in years. It’s wonderful. I’ve had tinnitus for over twenty years, and that can drive you crazy. I was also having dizzy spells. Since I’ve gotten my hearing aids, all that has stopped!”

Ken F. in Wesley Chapel

“I bought Oticon Delta hearing devices a year ago. I’m very happy with them, are comfortable to wear and cut out background noise.”

Mary K. in Sun City Center

“Dr. Sims was very helpful and my hearing aids work great! I didn’t realize how many sounds I was missing. Oticon Delta- Great!”

Vera R. in Tampa

“Dr. Sims’s kindness brought more pleasure than words can express”

“God Bless You”

Gabriela S. in Tampa

“Dr’s. Clark and Sims have expressed deep concern over Martha’s condition. We both want to thank them for their feelings and for the aid they let Martha borrow. The entire staff needs to be commended for their attitude and caring for us”.

“Thank you”

Rod R. in Tampa

“I’m pleased to relate a few of my pleasures after having bought my Oticon Delta hearing aids. They have helped me improve my lifestyle. They have helped me hearing the TV and my friends and family have been happy due to the same measure of tuning. I can communicate personally with my friends knowing I understand what they are saying to me.”

Elizabeth C. in St. Augustine

“My thanks to Dr. Jeffrey Clark for all the time he spent getting just the right aids for me! This office is very prompt on appointment times avoiding long waits and this office’s employees are very helpful when a call is necessary.”

“After trying out several other aids I was fitted with the open ear OTICON Delta hearing aids. I find them so easy to place in the ear and by matching the color of my hair behind my ear they are undetectable. I wear eye glasses for close reading and they are on and off all the time with no problem with the aids coming off- I highly recommend them!”
