Audio TalkBox

Contract short description

TalkBox ir akustisko signālu ģenerators runas saprotamības mērījumiem evakuācijas un paziņojumu sistēmās, kā arī telekonferenču vai citu audio sistēmu līmeņa izlīdzināšanai. Tas ļauj veikt pilnīgu runas saprotamības STI novērtējumu no runātāja mikrofona līdz klausītāja ausīm
