- Page 4 The Speech Transmission Index (STI) is a quantitative method of measurement covered in the International Electrotechnical Commission (IEC) standard 60268-16. These Gold Line meters require the use of a STI-PA test signal which was developed by TNO Human Factors Research Laboratories in the Netherlands, in conjunction with Bose and Gold Line.
- Page 5 STI measurements can be made without significant training. Once the STI-PA signal has been input to the system under test, a single button push on the DSP2B/BP will produce the STI, which can be converted CIS as specified in IEC standard 60849. The test only requires about 15 seconds.
