Republic Services Training Center: 5 Seconds Less Echo
A trainer in a room of 60 has one job: be understood in the back row. Republic Services has eight training rooms in Grand Prairie, built for 20 to 60 people each. We put acoustic walls in all eight and took 5 seconds of echo out of them.
In a training room, if the back row can't follow, the training didn't happen.

THE SPACE
Eight Rooms, One Question: Can the Back Row Hear?
Republic Services trains people in eight rooms at its Grand Prairie center. The rooms hold 20 to 60 people each. In a room that full, a trainer's voice has to carry to the back, and it has to arrive clean.
Five seconds of echo came out of those rooms. That tells us how long speech was hanging in the air before, and why clarity was the problem to solve.
What was getting in the way:
-
Echo. Each word lands on top of the one after it.
-
Distance. The farther the seat, the worse it gets.
Eight rooms is eight chances to get it wrong. We treated them as one project.
THE RESULT
5 Seconds Less Echo
in 8 Rooms
5 sec reverb reduction | Better communication | Higher sound clarity
Reverb is how long sound hangs in a room after someone speaks. Less reverb means clearer speech.
TECHNICAL INSIGHTS
FAQ
How much did echo drop?
By 5 seconds, across eight training rooms.
Why walls?
Acoustic walls absorb sound at the surface where speech bounces. That keeps speech clear across the room.
Can you work room by room?
Yes. This project ran from 2023 to 2026.
