Combining filters. Filters work together, and ear-level choices must match the same ear. Greyed-out choices have no matching members with your other selections. Choose Any, or use the clear button in a field, to remove one filter. Clear all filters resets the whole search, including the member comparison and the Show only choices.
Show only. Active in the last 90 days uses the member’s last forum visit. Hearing aids in profile includes current and past devices shared publicly.
Categories and matching. Categories explain the pattern; matching compares the actual curves and can pair opposite ears. With no other filters selected, every category is available to browse, and some categories may have no member-shared audiograms yet.
Derived loss types. Sensorineural includes labeled presumptions when no bone-conduction data is entered, including normal/near-normal hearing. Partial or uncertain bone measurements can leave the type unknown. Conductive (presumed) uses repeated air–bone gaps in unmasked bone results; masking and ear assignment are unverified.
