Noise Expert (acoustical engineers) measured the Field Sound Transmission Class (FSTC) for seven different walls in a Lockheed Martin office building. The building was going to be remodeled and some of the rooms were going to have sensitive activity that required an FSTC 50.
Noise Expert conducted noise and vibration measurements and evaluation in an office complex in Scottsdale, Arizona. A free weight gym is located between two offices. The clients in the gym regularly drop heavy weights that cause the floor to vibrate in the adjacent office spaces. One solution for the vibration transfer though a shared concrete floor is to float the gym floor.
