The SM50 was designed from the ground up by the inventors of STIPA, and is a fully compliant STI - Speech Transmission Index measuring device as specified in IEC-60268-16 4th ed. (2011). It offers two STI measuring modes: a quick screening mode, optimized for ease of use and for quick use, and a "Pro" mode that offers the most complete and versatile functionality of any Speech Transmission Index measurement to date. In addition, the SM50 is a fully IEC 61672 compliant Class 2 Sound Pressure Level meter
