  1. Digital Speech Level Analyser Gives you the information you need about Speech Performance ... FAST ...

  2. DSLA: A Precision Instrument • Purpose-designed (not based on a PC sound card) • 24-bit A-D and D-A conversion technology • Noise floor lower than -80dBm for balanced input • Dynamic range greater than 110dB for balanced input (noise floor to clipping) • The best quality platform available

  3. DSLA Speech Quality Display MOS prediction Reference surface – transmitted signal Degraded surface – received signal Error surface

  4. Wireless Network Hands-free Hands-free DSLA Handset port PC Ethernet Speech Quality Analysis for Handset to Handset Path (Same Location) Using One DSLA

  5. Wireless Network PSTN DSLA Analogue phone line Hands-free Phone line port Handset port PC Speech Quality Analysis for PSTN to Handset Path (Same Location), Using One Digital Speech Level Analyser (DSLA)

  6. Wireless Network DSLA Hands-free Handset port PC PC Hands-free Speech Quality Analysis for Handset to Handset Path (Different Locations), Using Two Digital Speech Level Analysers (DSLA) DSLA Handset port

  7. Wireless Network PSTN PC DSLA Phone line port PC Hands-free 9-18 Vdc input for vehicle use Speech Quality Analysis for PSTN to Handset Path (Fixed & Mobile Locations), Using Two Digital Speech Level Analysers (DSLA) DSLA Handset port

  8. Base Station Emulator Audio IN OUT Head & Torso Simulator (HATS) and Associated Components Handset Testing using Acoustic Test Components and Digital Speech Level Analyser (DSLA) Chamber

  9. Base Station Emulator Audio OUT IN DSLA Artificial Ear type 4185 or 4195 Mic. Pre-amp., 2690 PC Handset under test Artificial Mouth, 4227 Power Amp., 2716 Chamber Handset Testing using B&K Acoustic Test Components and Digital Speech Level Analyser (DSLA)

  10. Base Station Emulator Hands-free kit Audio IN OUT Head & Torso Simulator (HATS) and Associated Components Handset Testing using Acoustic Test Components and Digital Speech Level Analyser (DSLA) Chamber or vehicle

  11. Base Station Emulator Audio IN OUT 3 4 Degraded file Equalised file 2 Equalised reference signal (artificial mouth complement) 5 Degraded file, for comparison with wide-band reference Acoustic Chamber Head & Torso Simulator (HATS) and Associated Components Use of DSLA Equaliser to compensate for response of Artificial Mouth 1 Wide-band reference signal on PC

  12.
