8.2.1.1: hardware with speech output typically held to the ear must allow conversational gain of 18 dB or more (ANSI/TIA-4965 fixed and TIA-5050 mobile handsets are deemed to comply). 8.2.1.2: where volume is incremental, at least one step must give 12 dB of gain above the lowest setting.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
