I don't know any venue that has ALD to begin with.
I am sure some people confuse an ALD with an IEM too
In the United States, since 2010, the Americans with Disabilities Act requires that any public entertainment space using amplified sound must offer Assisted Listening Devices to people with hearing impairments. So if you are in the USA, that means pretty much every place that has amplified concerts or sporting events anywhere near you will offer ALDs or risk being in non-compliance with the ADA.
If you are not in the USA: never mind.
Lastly, I know some professional musicians who need both an IEM and an ALD, even if they don’t realize it yet. (Because they have damaged their hearing)
