A signal used by some assistive listening devices to send sound via infrared light waves
What is an infrared hearing system?
An infrared hearing system is an assistive listening device (ALD) that uses infrared light waves to transmit sound. This makes it ideal for people with hearing loss who want to hear sound in public places, such as theaters, churches, and classrooms.
How does an infrared hearing loop work?
An infrared hearing loop is a type of infrared hearing system that is installed in a permanent location. It consists of a transmitter, which sends out infrared light waves, and a receiver, which picks up the light waves and converts them into sound.
The transmitter is typically placed in a central location, such as the front of a room. The receiver can be worn by people with hearing loss, either as a part of their hearing aid or as a separate device.
When the transmitter is turned on, it sends out a beam of infrared light waves. The receiver picks up the light waves and converts them into sound. The sound is then amplified and delivered to the user’s ear.
What technology do audiologists use?
Audiologists use a variety of technologies to diagnose and treat hearing loss. Some of the most common technologies include:
- Immittance audiometry: This test measures the mobility of the eardrum and the compliance of the middle ear.
- Tympanometry: This test measures the pressure in the middle ear.
- Pure-tone audiometry: This test measures the softest sounds that a person can hear at different frequencies.
- Speech audiometry: This test measures how well a person can understand speech at different volumes and frequencies.
- Otoacoustic emissions: This test measures the echoes of sounds that are created by the hair cells in the inner ear.
What are the three types of hearing devices?
There are three main types of hearing devices:
- Behind-the-ear (BTE) hearing aids: These hearing aids are worn behind the ear and have a small receiver that sits in the ear canal.
- In-the-ear (ITE) hearing aids: These hearing aids are completely encased in the ear canal.
- In-the-canal (ITC) hearing aids: These hearing aids are smaller than ITE hearing aids and are partially inserted into the ear canal.
The type of hearing device that is right for you will depend on your individual needs and preferences. If you have a mild hearing loss, you may be able to get by with a smaller, less expensive hearing aid. If you have a more severe hearing loss, you may need a larger, more powerful hearing aid.
If you are not sure what type of hearing device is right for you, it is a good idea to talk to your audiologist. They can help you assess your needs and recommend the best hearing device for you.
If you are concerned about your hearing, it is important to see an audiologist for a hearing test. An audiologist can diagnose any hearing problems you may have and recommend treatment options, such as an infrared hearing system.
