Profoundly or severely deaf

You can apply for a National Concession bus pass if you are profoundly or severely deaf:

Hearing loss is measured in decibels across the normal hearing spectrum, as dB HL (Hearing Level). People are generally regarded as having a severe hearing loss if it reaches 70-95 dB HL and a profound loss if it reaches 95+ dB HL. The Department advises that the statutory minimum concession should be made available to people in these categories.
There is no statutory registration system for deaf people. However, many will be registered on a voluntary basis with their local authority social services department. The register is open to people who have varying degrees of hearing loss, so in checking the register a local authority is advised to check that the applicant is profoundly or severely deaf before issuing a national concession bus pass.
As in the case of blind and partially sighted people, local authorities may, where appropriate, require applicants to provide evidence of registration before issuing a pass, or evidence that they could register, for example, an audiological report, or a report from an aural specialist.

Based on the guidance are you profoundly or severely deaf?
