Division 1.3

Hearing and speaking requirements

Sufficient hearing confirmed by an audiogram, i.e.:

• hearing good enough to hold a phone conversation and to be able to hear warning sounds and radio messages.

The following values should be taken as guidelines:

• the hearing deficiency must not be higher than 40 dB at 500 and 1 000 Hz,

• the hearing deficiency must not be higher than 45 dB at 2 000 Hz for the ear with the worst air conduction of sound,

• no anomaly of the vestibular system,

• no chronic speech disorder (given the necessity to exchange messages loudly and clearly),

• the use of hearing aids is allowed in special cases.
