• Any combined rating equal to or greater than six
offers excellent use.
• Any combined rating equal to five is considered
normal use.
• Any combined rating equal to four is considered
usable.
Thus, if you use an M3 phone with a M3 hearing
aid you will have a combined rating of six for
"excellent use." This methodology applies equally
for T ratings.
