Mobility Testing

In mobility testing, accelerance, mobility and compliance functions are calculated. For structures with well-separated modes, estimation of natural frequencies and damping ratios is possible. Often done during troubleshooting using hammer testing.

Type 4720 - Echo Speech Source

Echo Speech Sound Source outputs calibrated signals for measuring a range of speech intelligibility parameters in conjunction with DIRAC 6. The received signal is picked up by a microphone and analyzed in DIRAC, which calculates an accurate qualification of the speech intelligibility through various parameters such as the Speech Transmission Index (STI).

With a calibrated speech source there is no need for external

equalizers or speech level adjustment. The signal can be set at an elevated level, making STI measurements possible - even if the background noise is significant. DIRAC 6 recognizes the output level and corrects calculations appropriately.

For STI measurements, it contains pink MLS signals. The MLS is far less intrusive than an e-sweep signal. In addition Echo Speech Source can be used to set the volume of PA systems using a male speech signal with a standard level of 60 dB(A) at 1 meter.
