Horizontal and vertical flank sound test stands (building acoustics)

The test stand is used to measure the horizontal and vertical standard edge sound level differences. The test stand complies with the requirements of DIN EN ISO 10140-5. The removable wall elements on the vertical test stand allow the specimen to be mounted in a test opening between two decoupled rooms.

For the measurement of the standard edge sound level difference, a broadband noise is radiated via a loudspeaker in the transmitter room.
