【摘要】：目的探討音樂測試材料在可接受噪聲級(acceptable noise level,ANL)測試中應(yīng)用的可行性。方法選取國家普通話水平測試用短文朗讀作品、普通話音樂、伴奏音樂三種音頻材料,制作成ANL測試材料,背景噪聲采用目前國際上通用的多人談話的語頻噪聲(babble噪聲),對40例聽力正常青年進行ANL測試并分析結(jié)果。結(jié)果普通話短文測試材料、普通話音樂測試材料和伴奏音樂測試材料下得到的最舒適響度級(most comfortable loudness,MCL)分別為39.10±7.43、43.85±9.53、44.10±10.83dB HL;最大背景噪聲級(background noise level,BNL)分別為37.91±8.65、44.52±11.23、43.65±12.89dB HL;ANL值(MCL-BNL)分別為0.98±4.90、-0.90±3.78、0.45±4.65dB。普通話音樂測試材料和伴奏音樂測試材料下的MCL值和BNL值均高于普通話短文測試材料(P0.05),但普通話音樂測試材料與伴奏音樂測試材料下的MCL值、BNL值均無統(tǒng)計學(xué)差異(P0.05),三種測試材料之間的ANL值均無統(tǒng)計學(xué)差異(P0.05)。結(jié)論音樂測試材料可應(yīng)用于可接受噪聲級測試;在音樂測試材料下MCL值和BNL值更高,提示正常人對音樂的接受度更高,音樂測試材料有無歌詞對ANL測試結(jié)果沒有影響。
[Abstract]:Objective to explore the feasibility of music test materials in acceptable noise level (acceptable noise level,ANL (acceptable noise level test). Methods three kinds of audio materials, namely, short text reading works, Putonghua music and accompaniment music, were selected for the national Putonghua proficiency test to make ANL test materials. the background noise was based on the babble noise, which is commonly used in the world at present. 40 young people with normal hearing were tested by ANL and the results were analyzed. Results the most comfortable loudness levels of Putonghua short text test materials, Putonghua music test materials and accompaniment music test materials were 39.10 鹵7.43, 43.85 鹵9.53 and 44.10 鹵10.83dB HL;, respectively. The maximum background noise level (background noise level,BNL) was 37.91 鹵8.65, 44.52 鹵11.23, 43.65 鹵12.89dB HL; ANL (MCL-BNL) was 0.98 鹵4.90, 鈮，
