Acoustics Measurement of the soundabsorption coefficient and the acoustic im- pedance by the tube method
Provides specifications for instruments designed to measure acoustic impedance, acoustic admittance, or both quantities, within the human external ear
Specifications for Instruments to Measure Aural Acoustic Impedance and Admittance (Aural Acoustic Immittance)
Acoustics. Testing of architectural acoustics. Determination of sound absorption coefficient and impedance in a tube.
Instruments for the measurement of aural acoustic impedance/admittance
Instruments for the measurement of aural acoustic impedance/admittance (IEC 1027:1991)
传递函数法测定法向入射条件下吸声材料的吸声系数,涉及阻抗管的使用、两个传声器的位置和数字频率分析系统。本方法也能用来测定吸声材料的表面声阻抗率或表面声导纳率。由于吸声材料的声阻抗率与它的物理特性(诸如流阻、孔隙率、弹性模量和密度)有关,所以本标准规定的测量方法在有关的基础研究和产品开发方面
