Research on the computation model of low-frequency noise tonality

  • For the low-frequency noise,the subjective tonal sense will be significantly improved when the tonal part which has higher sound pressure level near the center frequency is changed,including peak sound pressure level rais-ing and peak shape sharpening.Therefore,the impact of the peak signals must be fully taken into account for tonality model.Some consideration has been made for the current model in this aspect,however,the models are instability and a certain bias has presented with subjective results.In this paper,the existing model has been modified based on experimental research and analysis for Chinese people.
