Qsources – Precision Excitation for Noise & Vibration Engineering
Create the excitation. Measure the response. Understand the source.
Qsources’ offer’s specialized acoustic and structural excitation technologies to engineers who need more than a conventional sound source or vibration shaker. Designed to support accurate, repeatable measurements, Qsources solutions help investigate how structures vibrate, how sound travels, and how products respond to controlled excitation.
A key differentiator is the combination of compact design, integrated force sensing, and patented self-aligning suspension in its structural shakers. This helps reduce setup complexity and unwanted mechanical loading during modal testing and vibro-acoustic investigations. Its acoustic sources provide measurable volume acceleration or reference sound power for advanced acoustic analysis.
Technologies That Make the Difference
Structural Excitation – Small Shakers, Detailed Structural Insights
Qsources structural shakers are designed for applications where conventional shaker setups can be difficult to install, particularly in confined spaces or when measurements are needed at multiple locations. Depending on the model, integrated force and acceleration sensing supports frequency response function (FRF) measurements, experimental modal analysis, transfer path analysis, inverse load identification, and CAE model correlation.
Acoustic Excitation – Controlled Sound for Quantifiable Measurements
Qsources acoustic sources go beyond simply generating sound. Selected models provide real-time volume acceleration signals, supporting reciprocity measurements, vibro-acoustic modal analysis, and sound power investigations. Dedicated reference sources support sound power measurements, while the Qohm and Qoms2 address building and room acoustic applications.
