Even in a […]
Assessment of noise with respect to its effect on the intelligibility of speech
International Standard ISO/TR 3352:1974 “Acoustics – Assessment of noise with respect to its effect on the intelligibility of speech” provides methods for measurement and assessment of noise with respect to intelligibility. Example For a speech interference level of 35 dB, the maximum distance at which raised voice is considered to be satisfactorily intelligible is 15 […]
