Easy -to -use kit portable impedance meter for non -destruction and acoustic material tests
Hottinger Brüel & Kjær
About This Product
■ 9737 type portable impedance meter
This kit quickly measures the sound characteristics of the material without removing the material sample. This kit is composed of easy-to-use handheld device, LAN-XI data collection front end, and PC software. Since the object can be measured in the actual situation, it is ideal for verification after mounting acoustic materials and quality control after all manufacturing processes are completed.
■ Characteristics
This kit is composed of two micro hons, sound sources, and hand -helped impedance meters, including integrated sensors for measuring the temperature, temperature, pressure, and relative humidity. The impedance meter is connected to one front-end unit consisting of a LAN-XI oscillator module and a power amplifier contained in a convenient double LAN-XI casing.
Flat flange is designed for the optimal sealing and removable, so it is replaced with a panel that is completely adhered to a custom -made Bay -curved flange and completely adhered to the aircraft acoustic liner. You can maximize it.
■ Functional
・ Measure up to 155DB SPL
・ The 29mm inner diameter tube achieves optimal performance from 500Hz to 6,400 Hz, and can be measured to 50 Hz when combined with a wider optional tube.
・ Measurement of composite materials and direction -sensitive materials
・ Measurement by wide band, pure sound, or user -defined sound source
・ Calculation of nonlinear resistance change due to sound speed
・ Options for looping with increased OASPL or pure sound SPL
・ Sample holder in the tube correction with flange
■ Major acoustic parameters required in the actual environment
・ Impedance spectrum vs Overall sound pressure level (Oaspl) and acoustic resistance vs sound speed
・ Sound pressure and sound speed spectrum on the sample surface
・ Sound absorption rate
・ Acoustic reflection coefficient
・ Normalized impedance and advice
・ Acoustic resistance as a function of acoustic speed
・ Acoustic speed as a function of frequency
・ Single -layered perforated board sound effective opening area (acoustic Poaeff)
・ NFL characteristics of Acoustic R105, single -layered and multiple freedom panel
