Title: Hearing Loop Questions
Post by: Adam Kane on June 18, 2018, 04:23:44 PM
So...

Gotta venue that may want us to install a loop system. I've worked with them before during new construction (under flooring, replacing when flooring dude cuts through it, etc). This place is finished. It's on a slab with expensive marble flooring that they aren't about to rip up. Running anything around the base of the room isn't an option as they don't want to see it. Base trim doesn't look like it will come off without damaging it.

There is attic access above the room. My question is: has anyone ever run a loop conductor around the perimeter of the ceiling? This room has a vaulted ceiling that is about 10' at the outside walls and 16' or so at the peak.

Any ideas would be welcomed. I go to meet with them next week.

What’s the length and width of the room? Those heights of ceilings should not pose a big problem...the 10’ end is closer to ear height than running at floor level, and even the 16’ peak isn’t much further. You might even get away with a perimeter loop

Approximately 60x60ft. The attic is wide open (I've been up there before doing other work) and getting the loop to encompass the seating area shouldn't be a problem.

Do you need to control overspill? Are there rooms attached that would be affected by the loop signal spilling into then? If not then a perimeter loop will work fine. Just get yourself a good loop tester to make sure you are outputting a decent signal. I use Signet loop amplifiers. Here you can download a calculator to determine which amp you need

Overspill is not likely an issue.

Thanks for the link!

Why not just do an RF system with Neck loops?

There are bound to be people without hearing aids that need hearing assistance as well.

I had considered this and was planning on proposing this as well. They seem pretty dead set on a loop, although I have no idea why.

Over here loop systems are in every church and public building. They are incredibly handy. Especially for older people, they don’t have to wear anything. Their hearing loop just automatically picks up the signal as soon as they are in range.

There is great reluctance on the part of those who *need* to use these systems to acquire and return venue/show specific ALS hardware.

There are also ADA requirement for full assistance kits of receivers and earphones, regardless of the method - RF, induction, IR.
