72-76 MHz is an FM bandwidth used by some ALDs, or ALSs.

Although other users may share that band, interference is seldom a problem.

That band is used by most of the FM systems designed for people with hearing loss and until recently was unchallenged as the right place for assistive technology.

Receivers and transmitters in the personal ALD category which use 72-76 MHz are typically the size of a large beeper, and are not suitable for use in booted or embedded receivers that are now available in the 216-217 MHz FM band. Still, the can perform quite well, with little difference (if any) in actual sound quality when compared with the more expensive and convenient 216-217 MHz band equipment.

Users must choose the best "user interface" for them, a choice which may include: neckloop, silhouette, DAI or even headphones.

For those on a strict budget, some applications (like radio transmission of your TVs audio) to a small receiver driving a neckloop, silhouette, DAI or even headphones, you might look into 900 MHz systems marketed to the general public. They are not meant specifically for hard of hearing use, but can work well in limited situations and are dramatically cheaper than the other options, often costing less than $100 for both transmitter and receiver.
