Measurement System for Sound Level Difference Between Rooms
The RIONOTE Multifunction Measurement System can be used for measuring the sound insulation between rooms, using a sound generator (with speaker).
In order to facilitate system setup and eliminate the need for cabling between rooms, the microphone signal can be transmitted wirelessly by the Wireless Dock SA-A1WD to the RIONOTE unit for processing. The illustration below shows a system where the microphone in the source room and receiving room respectively is connected to a wireless dock with amplifier unit, to perform 1/3 octave band analysis of the sound in each room. Because the RIONOTE has wireless capability, it can be taken outside of the rooms under measurement. While being transmitted wirelessly, the measurement data are also saved on an SD card in the amplifier unit of the wireless dock, to prevent data loss in case of an interruption of the radio connection during measurement. When the measurement is completed, the measurement data in the amplifier unit are downloaded to the RIONOTE unit. Up to four RIONOTE units can be connected wirelessly to the SA-A1WD, making it possible to perform sound measurement and analysis in up to 16 channels (4 channels x 4 units). (For 1/3 octave band analysis, the maximum is 3 channels x 4 units = 12 channels.) System Diagram
