Acoustic Testing for Launch Qualification and High-Intensity Noise Environments 

Precise DFAT and RFAT control with high-throughput data acquisition for spacecraft acoustic qualification.

Acoustic testing is essential for launch qualification, validating how spacecraft and payloads respond to high-intensity noise. Our platform supports Direct Field Acoustic Testing (DFAT), Reverberant Field Acoustic Testing (RFAT), octave band analysis, sound intensity measurement and advanced acoustic analysis. With DFAN and RFAN control, synchronized data acquisition and deep post-processing, m+p international delivers precise acoustic environments, stable spectral shaping and high-confidence results for vibration and acoustic load qualification.

Launch vehicles generate extremely high sound pressure levels and broadband acoustic loads that must be reproduced consistently in DFAT or RFAT conditions.

m+p DFAN and RFAN provide stable spectral control with multi-microphone feedback, delivering accurate DFAT and RFAT environments for launch qualification with consistent OASPL and octave-band performance.

Loudspeaker distortion, microphone drift and energy absorption by large payloads can destabilize octave bands during high-intensity acoustic testing.

Dynamic equalization ensures precise octave band shaping, keeping SPL and spectral content within tight tolerances during DFAT, RFAT and progressive wave tube acoustic testing.

Large spacecraft structures can amplify acoustic loads through resonance, creating local stresses that must be understood for safe deployment.

Combined acoustic excitation and accelerometer data provide clear correlation between acoustic loads and structural resonances, supporting acoustic resonance testing and advanced acoustic analysis.

Some launch qualification scenarios require simultaneous acoustic loads and vibration excitation to simulate realistic launch conditions.

m+p systems synchronize shaker vibration with DFAT or RFAT noise fields, enabling accurate combined-load simulation for noise and vibration testing under true launch conditions.

Broadband noise alone cannot reproduce the slow, high-energy acoustic components present during launch events.

Sine Burst and Sine Beat profiles generate controlled quasi-static acoustic loads, enabling realistic simulation of low-frequency pressure events during acoustic vibration testing.

Launch qualification requires large, synchronized datasets from microphones, accelerometers and environmental sensors.

All channels are recorded in parallel at high resolution, enabling detailed FFT analysis, octave band analysis, sound intensity measurement and sound quality analysis in the Analyzer.

DFAT and RFAT depend on uniform distributed acoustic fields, which must be validated before running qualification levels.

m+p tools support sound power analysis, sound intensity scanning and microphone array evaluation, ensuring uniformity requirements for DFAT testing and reverberation chamber testing are met.

Facilities operating multiple acoustic rigs or test rooms need centralized visibility and process automation.

CODA and the REST API provide remote monitoring, automated control and full traceability, allowing labs to scale DFAT and RFAT testing without increasing operational workload.

Acoustic laboratories rely on climate chambers, amplifiers, signal routing systems or external measurement hardware requiring synchronization.

Digital I/O integration enables coordinated control of amplifiers, chambers and auxiliary equipment, supporting complex acoustic simulation workflows and launch readiness testing.
