What is Assistive Listening Devices

An assistive listening device (ALD) is type of device that can help you function better in your day-to-day communication situations. An ALD can be used with or without hearing aids to overcome the negative effects of distance, background noise, or poor room acoustics. So even though you have a hearing aid, ALDs can offer greater ease of hearing (and therefore reduced stress and fatigue) in many day-to-day communication situations.

Hearing aids + ALDs = Better listening and better communication!

Types of ALDs

  • Personal frequency modulation (FM) systems
  • Infrared systems
  • Induction Loop Systems
Personal frequency modulation (FM) systems:

FM System Improves the Signal-To-Noise Ratio and thus the user’s ability to understand Speech in Noise. Three major Facts as background noise, Reverberation and distance are influence the SNR & Quality of Speech Signal. By developing the Signal of interest via FM (Radio Wave) The strength and quality of sound remain constant across the distance from the speak to the hearing impaired individual. FM System consists of a transmitter with a microphone and a speaker, which pick up the signal via radio wave directly from the transmitter.

MOULDS/ Noise Plugs

“Ear mould is a device worn inserted into the ear for sound conduction or ear protection. Earmolds are anatomically shaped and can be produced in different sizes for general use or specially cast from particular ear forms. Some users specify how hard or soft they want their mould to be, an audiologist can also suggest this. As a conductor, it improves sound transmission to eardrums. This is an essential feature to diminish feedback paths in hearing aids and assure better intelligibility in noisy-environment communication. The main goal in wearing earmolds is to attain better user comfort and efficiency. Earmolds (and their tubes) often turn yellow and stiff with age, and thus need replacement on a regular basis. The job of making earmoulds is very time consuming and skilful, each one is made individually.

There are special kinds of moulds which can be used for ear protections by normal hearing individuals, for more information please contact our Audiologists.”

Hearing Aids Batteries

Hearing aids require a lot of power and energy. For this reason, zinc air batteries are most often used because they produce a large amount of energy despite their very light weight.

Each hearing aid requires a specific battery size and, thanks to customer feedback, companies have now adopted a universal system to help customers better remember and match their battery with their aid. Hearing aid battery sizes can now be identified on all battery manufacturers’ packaging using the following colors.

  • Yellow – Size 10 (230)
  • Orange – Size 13
  • Brown – Size 312
  • Blue – Size 675

Battery Tips

  • Always keep hearing aid batteries away from children and pets.
  • Never place or carry batteries near metal objects such as coinage as it may cause them to short-circuit, which can cause leakage or explosion.
  • Zinc air batteries have a peel-off tab that exposes the battery to air. The tab should only be removed when the user is ready to replace the battery, because putting the tab back on has no effect since the battery has already been activated.
  • To maximize the life of your hearing aid battery, it is best to read all literature and manuals to ensure maximum safety and efficiency.
