There are many options for assistive listening technologies. This blog post provides a comparison between the three technologies used in assistive listening.
(NOTE: When this article was originally written the percentage of Tele-Coil equipped hearing aids in the U.S. were fairly low, but now most hearing aid manufacturers are offering this technology and the percentages are increasing)
This chart offers a side by side comparison of some of the considerations for each type of technology.
|Consideration||RF Technology||Infrared Technology||Induction Loop Technology|
|Can be used with a hearing aid that has a “T” switch without ANY other equipment||No||No||Yes|
|Can be used with a hearing aid that has a “T” switch but requires a neck loop plugged in to an FM or IR receiver||Yes||Yes||Not Applicable|
|Relative convenience level for individuals with a hearing aid that has a “T” switch||Medium||Medium||Very High|
|Relative convenience level for individuals with a hearing aid that DON’T have a “T” switch||Medium||Medium||Medium|
|Relative cost of installation for a new building||Low||Medium||High|
|Can be used for applications beyond assistive listening such as audio description, language interpretation, etc.||Yes||Yes||No|
|Maximum number of simultaneous channels||6||32||1|
|Secure. Signal does not travel outside the room||No||Yes||No|
|Relative audio quality||High||High||Medium / High|
|May interfere with equipment within the facility (such as a mixing console)||No||No||Yes / Possible|
