The Echo Speech Source features 5 different, calibrated signals, that DIRAC room acoustics software can calculate into speech intelligibility parameters.
The modulation transmission indices for the 7 octave band frequencies can be processed to arrive at the Speech Transmission Index (STI), which takes into ...
The parameters validated were the reverberation time and the speech intelligibility. Brüel & Kjær's ODEON version 10.0 was the simulation software used to ...
Software to measure room acoustical parameters in the field or laboratory according to ISO 3382 (room acoustics), ISO 18233 (analysis methods) and IEC 60268-16 ...
Junto con DIRAC 6, puede realizar mediciones de STI (índice de transmisión del habla). El software reconoce automáticamente el nivel de salida de habla y ...
We can understand the effect of absorption by measuring, at a given position in a room, the sound pressure level caused by a steady sound power source. Instead ...
The minimum range for ISO 3382-1 is the full octave bands from 125 Hz to 4 kHz, and for speech transmission index (STI) measurements, the 8 kHz full octave band ...
The. PB word score correlates well with an index of speech intelligibility, the speech transmission index (STI). (Ref.[3]), as shown in Fig.2. The measurement ...
DIRAC, running on a laptop, switches on the speaker test signal and instantly calculates the speech intelligibility indices from the sound level meter.
