Aerospace & Defence Acoustic Imaging Solutions

Acoustic imaging is a specialised technology that combines an array of precision microphones with high‑resolution optical imaging to locate and visually represent sound sources on complex structures. In aerospace and defence environments, this capability is essential for pinpointing noise emissions, structural defects, leaks, and other anomalies that traditional measurement techniques cannot reliably reveal.

An acoustic camera generally consists of a microphone array and an optical camera whose data is simultaneously acquired to give a representation of the location of the sound sources. Acoustic imaging enables you to pin-point the exact position of any noise emitting sources wherever it comes from on the aircraft.

Why Does Acoustic Imaging Matter in Aerospace & Defence?

In modern aerospace and defence engineering, acoustic imaging plays a central role in rigorous testing, development and maintenance processes:

Noise Source Localisation: Acoustic imaging allows engineers to pinpoint sound emission points anywhere on aircraft structures or defence hardware with exceptional clarity, aiding NVH (noise, vibration and harshness) analysis and structural integrity assessments.
Fault Diagnosis: Advanced imaging systems help detect mechanical deterioration, airframe leaks, partial electrical discharge, and other latent issues before they escalate into critical failures.
Enhanced Safety and Compliance: By visualising acoustic signatures, teams can validate design changes, support certification processes and ensure that noise or vibration issues comply with regulatory and operational standards.

How Does Acoustic Imaging Work?

An acoustic camera uses a dense array of microphones to capture sound waves across a broad frequency range. By processing these signals with advanced beamforming and visualisation algorithms, the system produces a colour‑coded map that shows the precise location and intensity of sound sources overlaid on live images of the test object.

This method provides real‑time feedback, enabling faster fault identification and deeper insight into complex acoustic behaviours in aircraft engines, structural panels, and defence systems.

Applications Across Aerospace & Defence

Aircraft Design and Production:
Acoustic imaging supports both prototype evaluation and production quality control by identifying and mitigating noise sources that could affect performance, comfort or certification.

Maintenance, Repair and Overhaul (MRO):
MRO teams use acoustic imaging to inspect engines, turbines and airframes for wear, fatigue and hidden faults without disassembly, reducing downtime and inspection costs.

Systems Integration:
For integrated defence systems and avionics, imaging tools contribute to ensuring that mechanical and electronic subsystems operate within acceptable noise and vibration limits.
