Electroacoustic measurements

ISVR Consulting has extensive test facilities including Anechoic rooms and a Loudspeaker Listening Room. We also have a well equipped laboratory for electroacoustic test measurements on loudspeakers, microphones, headsets, headphones, telephones, handsets, alarm sounders, electronic sirens, pagers, ear-inserts and hearing aids. We also carry out direct speech intelligibility measurements of communications systems, and determine objective measures of intelligibility such as Articulation Index and the Rapid Speech Transmission Index (RASTI).
