Hearing Loss Simulation Test
The HLS offers a simulation of the hearing loss through the audiometric headphones or the high
frequency headset and is primarily aimed at the family members of the hearing impaired. It is a valuable
tool as a hearing loss in many families may result in frustrations and misunderstandings. Knowing what
the hearing loss actually sounds like gives an impression of what the hearing impaired goes through
every day.
