My motivation for the first ADA Calculator was simple. I simply knew there had to be a solution to repeatedly answering the question, “What do I need to do to meet the ADA’s Assistive Listening requirements?”
Every day I was grabbing the 2010 chart and a calculator and running through the math for someone. It got to be a redundant task pretty quick. I knew there had to be a better way; I just had to define it.
I originally created a short spreadsheet that covered up to five hundred seats. When a call came in exceeding the chart, I would take a few minutes and extend it out a little farther. Then it struck me. What if I took it out to 100,000 seats, and gave it pop-up window functionality?
First, select the calculator type, USA (for Americans with Disabilities Act - ADA), California (for California Building Code), or Australia (for Australia's Disability Discrimination Act 1992). Enter the seating capacity and the number of minimum assistive listening devices required and the minimum number of neck loops will automatically populate based on the calculator type selected.
