Facilities and Instrumentation
The Fluids, Acoustics & Vibration group is equipped with advanced instrumentation and facilities for the experimental analysis of noise, vibration, and fluid–structure interaction. Our laboratory supports research, development, and consultancy projects across a wide range of sectors, including aerospace, automotive, manufacturing, and the built environment.
Our test infrastructure includes a variety of ISO and ASTM-compliant apparatuses for acoustic material characterisation, sound power measurement, airflow resistance, and dynamic mechanical analysis. These standardised setups enable reliable and reproducible testing in accordance with industry norms. Prototype and material testing services are available through Trinity College Dublin’s consultancy office.
