Acoustic Applications

Here are the acoustic PULSE solutions that have specific relevance to the Aerospace/Defence industry:

Noise Source Identification (NSI) and Mapping
We offer a complete range of noise source location tools including PULSE Acoustic Test Consultant (ATC) designed to simplify NSI measurements and providing measurement guidance and validation tools. 3D mapping software allows the visualisation of sound fields and the calculation of partial or total sound power.

Acoustic Imaging
Our beamforming solution consists of a numerically optimised array with a powerful PULSE-based analysis and display package. This combination provides high quality results, practically free of the spurious results (Ghost images) that commonly affect beamforming measurements. Now, you can visualise the sound fields of both large objects such as trains, cranes, planes, and ships, and smaller objects, such as car engines, right up to 20 kHz.

Acoustic Material Testing
PULSE Material Testing is a complete system for making acoustic impedance, absorption or transmission loss measurements on material samples in the 50 Hz to 6.4 kHz frequency range. The system consists of PULSE Material Testing Program, our impedance or transmission loss tubes, and other items such as a precision power amplifier, cabling, and dedicated microphones.

NSI - Intensity Mapping

Noise Source Identification (NSI) is an important method for optimising the noise emission from a wide range of mechanical and electro-mechanical products like vehicle engines, components , aircrafts, appliances, power tools, industrial machinery, etc.

In addition, selective intensity may be used to further identify the internal root sources and radiation mechanisms involved. ...

Acoustic Material Testing

Improving cabin acoustic comfort by providing optimal acoustic material performance against weight and volume is one of today’s challenges in the ground transportation and aerospace industries. Protection against noise in dwellings and at the workplace most often requires the appropriate selection of noise-reducing treatments.

Noise control materials can be tested in terms of their ...
