The arrangement of Noiseless Sound and Vibration High Speed Camera Recordings

Original language description

The high speed camera recordings require the use of intense illumination. When the vibration of a sound source element and sound has to be recorded simultaneously with high speed camera and microphone the audio record is affected by the noise of cooling fans of used devices e.g. a powerful lamp. The noiseless recording condition is essential in the usual sound and vibration causality studies. The paper presents a possibility of the noise elimination with Fans-off device used in the research of the causal relation between violin string vibration and tone sound. The high-speed camera is operating at 60 kfps which needs the illumination with high-power 1 kW spotlight. The device switches all cooling fans off for the necessary time periods prior the measurement and thus ensures an apparatus noiseless operation during the audio/video recording. After the recording the device automatically switches the fans on to ensure the proper equipment cooling. The device provides the audio/video triggering and synchronization as well. An example of result is presented; more about discovered causality see in Full Paper link at: http://viennatalk2015.mdw.ac.at/?page_id=13002&pap=36.
