床衝撃音レベルの評価指標及び主観評価との対応に関する研究

抄録

We experimented rating of impact sound pressure level by hearing impression with floor impact sound including life sound. And we select the best evaluation index that has a high correlation in hearing impression. As the result, it is shown that maximum A-weighted impact sound pressure level LA,Fmax is better for heavy impact source than L-Number, and arithmetic average of sound pressure levels in octave bands L (63-4k) is better for light impact source than L-Number. Next, we examined the correspondence of LA, Fmax, L (63-4k) and hearing impression.
