Deaflympic eligibility requires a hearing loss of at least 55 dB in the better ear, and all hearing aids and cochlear-implant processors must be removed during competition so that every athlete competes under the same silent conditions.
The eligibility standard
Two rules together define who may compete:
- A hearing loss of at least 55 dB in the better ear. The threshold is measured on the ear that hears more, not the ear that hears less.
- No amplification during competition. Hearing aids, cochlear-implant external processors and any other hearing device must be taken off before the athlete competes.
Notice how carefully the word "better" is doing its job. Suppose the criterion used the worse ear: an athlete with a totally deaf left ear and perfectly normal hearing on the right would qualify — and would then have an enormous advantage in an event where nobody else can hear the starter. Anchoring the standard to the better ear guarantees the loss is substantial in both ears, so the field is genuinely level.
The second rule closes the other loophole. A modern hearing aid or cochlear implant can restore a great deal of functional hearing; an athlete wearing one would hear the gun, the referee's whistle and their opponents' movements while nobody else could. Removing all devices makes the silence equal.
What that silence changes about the sport
Because no athlete can rely on sound, the Deaflympics replaces every auditory cue with a visual one:
- Starts are signalled by a flashing light rather than a starter's pistol.
- Officials use flags and hand signals instead of whistles.
- Team communication happens visually — through sign language and eye contact rather than shouted calls.
This is why the Deaflympics is run as its own Games rather than as a category within the Paralympics: the entire competition environment, not just the classification, has to be adapted.
Why the other thresholds are wrong
| Option | Why it fails |
|---|---|
| (a) 25 dB | Only a slight loss. Athletes with near-normal functional hearing would qualify, defeating the purpose of the Games. |
| (b) 40 dB | A real but moderate loss — still below the prescribed standard. This is a distractor built from a lower audiometric grade. |
| (c) 55 dB | ✓ The prescribed threshold, measured in the better ear. |
| (d) 90 dB | A profound-loss threshold. Setting the bar this high would exclude a large number of genuinely deaf athletes who are well below 55 dB in both ears — far stricter than the actual rule. |
