Abstract

We examine the acoustic characteristics of wind tunnels with and without acoustic foam liners, illustrate how the aeroacoustics of the liner can control the sound in the facility, and provide analytical evidence on the existence of the acoustic impedance of the liner in altering the dipole strengths of the wall’s roughness sources that produce sound in the facility.
