STI Measurements

Sound installations for evacuation and broadcasting are used in various settings, including places of worship, hospitality venues, offices, greenhouses, courtrooms, retail environments, stations, airports, and healthcare institutions. These systems are crucial for ensuring clear communication with individuals present, particularly in emergency situations. In terms of safety, it is essential for evacuation and public address systems that announcements are clearly audible everywhere on the premises. Speech intelligibility is checked by measuring the Speech Transmission Index, STI for short. Following the measurement, the correct sound level can be figured out and the perfect settings of the audio equipment determined. In addition, STI measurements are also performed for the correct adjustment of Sound Masking systems. After all, the Sound Masking must be set so it works optimally. Only that way, the privacy of your visitors can be guaranteed and the concentration of your employees can be safeguarded.
