Signia pure primax 7 (119/60)

what are the 119\60 numbers designating?

Page 34 of Product Portfolio Spring 2017 (fullscreen it’s a wide page) second column Medium 60 receiver 119 dB.

I have seen all that before, just never knew what the # designated, So medium receiver? with a 119 db max output? I guess this will handle my hearing loss. Looks like the lows are on the upper end and my high freq. loss is on the low end of working spectrum? .
Thanks again!

Also, the low end of working spectrum changes depending on what type of dome you wear (open/closed fit). Here’s more info (beginning on page 4) for the receivers;
