Bryan Lockwood has written in with a tip on a site that makes it very easy to find out whether the mobile phone you are shopping for will be compatible with your hearing aids. PhoneScoop.com has a phone finder which lets you search for hearing-aid compatible phones, including their ‘M’ and ‘T’ ratings. When you get there, click ‘show all options’ and then scroll to the middle of the page where you will find a list under the heading Hearing Aid Compatible. Then you can check off the options you need. M3 or greater means your hearing aids microphones won’t get interference from the phone; T3 or greater means the phone will be compatible with the telecoils in your hearing aids which, if you have them, transmits the voice signal directly into your aids without distortion by the microphone. I’ve written a lengthier piece on finding the right mobile phone on the Healthy Hearing web site which gives more advice as well.
