Hearing loss simulation (HLS)
The HLS of f ers a simulation of the hearing loss through the audiometric headphones or the high f requency
headset and is primarily aimed at the f amily members of the hearing impaired. It is a valuable tool as a
hearing loss in many f amilies may result in f rustrations and misunderstandings. Knowing what the hearing
loss sounds like gives an impression of what the hearing impaired goes through every day.

Open the AC440. To perf orm the HLS counselling, an audiogram is needed. You should theref ore
start by perf orming Air Conduction Audiometry (as described in section 1.6) or retrieving an old
audiogram in the List of historical sessions.

When an audiogram is present, enter the HLS screen by selecting Menu | Tests | HLS.
3)
Select headphones or inserts in the channel 1 output dropdown list.

the hearing impaired may not be able to hear anymore such as some speech sounds and other
sounds that are likely to occur in everyday surroundings.
6)
It may be advisable to start the simulation session by letting the relative listen to the input signal with
his or her natural hearing f or a moment. This is likely to have a strong ef f ect when having to compare
