• Resumen

  • To get more sustainable building acoustics design and realisations, vibration velocity level is an interesting airborne sound insulation estimator, facing classical sound pressure level-based methods. However, the right sensors and data acquisition systems employment must be the proper one for the application. Instrumentation inherent noise is critical when dealing with high insulation ratings. Testing of limit minimum measurement levels is suggested and analysed.

    Results show arranged typical set-ups performance, and a use proposal is recommended.
