Using the portable XL2 provides accurate measurements on-site and immediately provides a detailed view of the acoustics”. Moon reported: “Our customers find the convenience of the handheld XL2 Acoustic Analyzer to be particularly interesting as opposed to using Smaart Live Software. The second half of the seminar was devoted to building acoustic applications for airborne and structure-borne sound insulation measurements.

Furthermore Moon showed how to quickly verify 100V lines using the impedance test of the handheld Minirator MR-PRO. How to measure and improve speech intelligibility was discussed, identifying the parameters that most influence the intelligibility sound pressure level, reverberation time RT60, signal-to-noise ratio, delay lines etc. It allows to evaluate the effect of room modes upon the clarity of sound reproduction. Short window length in seconds, used for peak and trough RMS measurement. Statistics are calculated and displayed for each audio channel and, where applicable, an overall figure is also given. A CD containing unique test signals is available. Display time domain statistical information about the audio channels. T 60 0.163 V / ( S a) s (9) a 18 for the Example 2 room with T 60 630 ms. In the first block he introduced the XL2 Analyzer as the portable solution for on-site commissioning and service of electro-acoustic sound systems. The sound decay time or reverberation time T 60 is related to the average wall absorption coefficient a by Sabines formula. Simple Measurement of Speech Intelligibility lead the participants through the workshop.

The half-day workshop covered the commissioning, setup and service of installed sound systems, supported by the handheld XL2 Audio and Acoustic Analyzer.Ĭustomers joined the seminar from a variety of industries, such as broadcasters and technicians from major movie theatres and concert halls. Sovico stages NTi Audio seminar in Korea The Korean NTi Audio Partner, Sovico, held an audio-acoustic measurement seminar on the 26th September 2013.
