A hearing aid is a battery operated device inserted either into or behind the ear that amplifies and changes sound to allow for improved communication. For people with hearing loss, hearing aids may be required for one or both ears. All hearing devices have the same three basic components:
- a microphone that picks up the sound and allows it to be converted to an electrical signal
- an amplifier that increases the size of the electrical signal
- an earphone that converts the increased electrical signal back into sound.
There are many different types of hearing aids with some examples including:
- computerised aids which can be programmed specifically for each individual
- wide dynamic range compression aids which amplify soft sounds and lessen loud sounds
- directional microphone aids which allow the listener to switch between all direction listening and directional listening
- noise reduction aids which reduce background noise
- multiple channel aids which allow for each part of the signal to be adjusted independently, particularly useful for use with mobile phones and other technology
- water resistant aids which allow for use in damp conditions.
Workplace solutions and adjustments
For a person who has a hearing difficulty, a hearing aid may assist them to communicate more effectively in the workplace. However as hearing aids are considered medical aids, funding is not available for these through the Employment Assistance Fund.
Financial assistance may however be available from the Australian Government via the Hearing Services Voucher scheme providing the person meets the eligibility criteria. For more information see the link in the related links section.
There are various other options that can also assist someone with a hearing difficulty in the workplace including:
