Estimation of Acoustic Characteristics for Low-Frequency Sound-Absorbing Structure Samples with Different Hole Geometry by Transfer Function Method at High Sound Pressure Levels
The acoustic characteristics of low-frequency sound-absorbing structure test samples with extended necks under high sound pressure levels were examined. An assessment of acoustic absorption and viscous dissipative losses was conducted for samples with round holes and holes in the shape of a slot and a star-pentagram.
