Abstract
Objective To study the attenuation effects of headphones and insert earphones on sound of different frequencies in sound field testing.Methods 40 people with normal hearing were selected to measure the hearing thresholds without earphones of both ears under sound field conditions,and then wear headphones and insert earphones in both ears,when the earphones did not give sound,the hearing thresholds of both ears after wearing different types of earphones were measured under sound field conditions.Compare the attenuation effects of different types of earphones on sound of different frequencies under sound field conditions.Results The sound attenuation values of headphones in the 0.25-8 kHz octave range were 6.13±2.40 dB HL,7.00±3.36 dB HL,12.50±3.92 dB HL,18.75±5.03 dB HL,28.25±6.56 dB HL,17.50±5.99 dB HL,respectively;The sound attenuation values of insert earphones in the 0.25-8 kHz octave range were 16.88±5.27 dB HL,18.13±5.27 dB HL,22.38±4.08 dB HL,31.25±4.49 dB HL,36.13±5.49 dB HL,35.50±6.68 dB HL,respectively.Conclusion The attenuation effects of two different types of earphones at different frequencies are significant,The attenuation values of sound increased with the increase of frequency,and the effect is more significant in the range of 1-8 kHz,and the attenuation effect of insert earphones is significantly better than that of headphones.关键词
