Acoustic performance: 67 Hz cut-off frequency, 22 dB(A) background noise, accredited ISO 3745 Class 1 verification. Room 6.56 × 5.56 × 3.83 m, broadband absorbent lining, full structural isolation from the building, decoupled test bed, acoustic motor enclosures and shaft silencers. Instrumentation: 10 IEC 61672 Class 1 microphones, triaxial accelerometers, Simcenter SCADAS Mobile (16 channels). For testing under load, the chamber operates together with the NAIePWT e-axle test rig (2 hub dynamometers, 500 kW / 3.19 kN·m each), whose dynamometers sit outside the room, acoustically isolated.
