This paper discusses main requirements of PN-B-02151-4:2015 standard in relation to designing of rooms for speech. Main relations between room volume, reverberation time, background noise level and speech transmission index STI were described. Examples of measurements from two Cracow primary schools were also included.
Keywords: speech intelligibility, STI, reverberation time, background noise.
